Contingency plans lengthen past server hardware and application. crucial facts ought to be available, even with environmental circumstance and there are lots of benefits of a incredibly available MDE environment: software stage clustering eliminates single elements of failure inside the administration console; automatic choices of attainable cluster contributors for original connection requests; utilization of database clustering; and, mediocre database ensures any cluster nodes hold entry to updated tips.

    most of the products available forward from legacy application, or an on-premises history reply adapted for the cloud. MDE was born in the cloud with the theory purchasers might hold complete control on the position they want issues to be. The skill of remonstrate store encryption offers the skills of comparatively cheap storage within the cloud, without compromising safety. information is slash up, in an effort to decrypt it, cloud suppliers would should spoil into Amazon and Azure, and gain access to the corresponding encryption keys.

    MDE offers the capability to deploy remonstrate hold gateways that, below entry policies, encrypt statistics before being despatched to remonstrate rescue repositories such as AWS S3, Azure, or IBM Cloud remonstrate store. purchasers needn't depend on a single cloud remonstrate rescue and may slither cloud carrier suppliers at their leisure without it being a drawn out and intricate procedure.

    DB2 Security with any the Trimmings | killexams.com true questions and Pass4sure dumps

    DB2 Security with any the Trimmings

    At a major original England-area insurance provider, a database engineer who asked not to be identified in this article, describes the management of security for her mainframe databases as "a nearly-impossible, labor-intensive task - if any they had to exhaust were IBM's own security administration utilities."

    She reports that her company has over 600 IBM DB2 databases running in 13 LPARs across eight mainframes distributed across two, geographically separate data centers.

    "About 8,000 conclude users at the company hold controlled access to the literally hundreds of volumes of DB2 data on systems which they are migrating to DB2 version 5.1. They are moreover in the process of migrating from [IBM] MVS to the OS/390 operating system to achieve Year 2000 compliance," says the engineer.

    "While IBM did a remarkable job with DB2, its security administration tools are inadequate to hold up with the changes that occur in their environment on an almost daily basis: changes in user access, the maintenance of remonstrate security and the securing of access to original transactions. Their database administrators (DBAs) would be spending any of their time just doing security work if any they had were DB2's own security utilities. It is just not an option not to hold a second [security] administration package for DB2."

    To enhance the security administration capabilities delivered with IBM DB2, the engineer reports that her company uses RC/Secure from Platinum Technology Inc. (Oakbrook Terrace, IL). With RC/Secure, she says, "We can let their security administration personnel execute the busywork of [granting and revoking access to DB2 database objects], while letting the DBAs focus on the intelligence work of database design. Platinum's product provides for cleaner security operations and productivity improvements over endemic DB2 security applications."

    In DB2's defense, the engineer concedes that her company has not looked closely at any changes in DB2 security delivered with the original version of the IBM database. Platinum's RC/Secure has become a fixture at the company over a period of years and she has slight incentive to change something that works.

    DB2 Security: An break to Enhance

    IBM, which has delivered DB2 since its branding in 1994 to more than 11,000 organizations and more than 40 million conclude users worldwide, has been actively evolving the product from an MVS-only mainframe database to a universal data base, according to Hershel Harris, Director of Database Technology with IBM's Software Solutions Division.

    Harris briefly recounts some watershed accomplishments in the development of DB2. "In 1994, they released an AIX and OS/2 version of the product. In 1995, they provided a parallel edition for data warehousing and a UNIX edition for Sun Microsystems and Hewlett-Packard. In 1997, they released the Universal Database (UDB) edition, adding remonstrate extensions, support for OLAP and OLTP applications and additional support for parallel databases that enabled data to be split across multiple nodes in a clustered environment. This year, they announced OS/390 DB2 UDB. Version 6, which should be available in 1999, extends the capability of UDB to understand objects. The family of products now runs across multiple operating environments, including NT, UNIX, OS/390, AIX and other flavors of UNIX. They are no longer a only mainframe product, but they are disdainful of their mainframe heritage."

    Built around the relational database model, says Hershel, DB2 delivers "built-in security based on privileges." He explains that, for every user with a valid ID or group membership, DB2 DBAs can exhaust the product's endemic security features to control what the user can execute with the database objects.

    "This goes beyond access. For every remonstrate and every user, specific privileges can be set up, including read, write, delete, update and run. The objects can be tables, views or procedures, and the privileges can be defined at a very granular level."

    Hershel says that generic SQL data control language statements such as grant and REVOKE may be used readily to control remonstrate access. He adds that IBM will do available in Version 6 of the OS/390 DB2 UDB product a suite of Administrative Tools similar to those that already ship with distributed platform versions of the product, "We hold in Version 5.2 [of their distributed systems product], an easy-to-use, NT-based Administration Tool that allows both graphical and Web-based administration of any distributed DB2 servers. This tool set is being added to [our OS/390 DB2 product] with its release in 1999."

    Hershel is awake of the availability and exhaust of third party products in conjunction with the IBM database, which he describes as "complimentary to the product."

    "IBM encourages complimentary product development by other companies. In the zone of DB2 security administration, there are probably a number of companies that deliver products to enhance the capabilities delivered with DB2. These tools may provide a graphical user interface to security administration using IBM's application programming interface. Some products emphasize enhanced query capabilities or enhanced reporting. Some try to integrate system plane security with DB2. One company showed me a demonstration recently of an application that enabled speech recognition technology and its exhaust with DB2 database security administration. In general, they are very supportive of these efforts."

    Opportunities to enhance DB2 in a complimentary manner hold been exploited by numerous companies, including Platinum Technology, according to Pete Peterson, Vice President for Database Administration Products at Platinum.

    Peterson says that RC/Secure answers a necessity within companies to simplify the model for managing authority, "With DB2 version 5, IBM allows RACF or external security products to be used in administering security within DB2. It is not a very straightforward procedure and it is difficult to create application and user domains using IBM utilities. Companies can gain a lot of [security administration efficiency] if they had a simple way to pass a hierarchy of privileges from one user to another without having to redo everything."

    RC/Secure, according to Peterson, is designed as a "management layer on top of DB2 - but not a run-time layer." He explains that changes made to security privileges may be applied on an ad hoc basis or in batch mode and suggests that the latter manner continues to be preferred by security administrators. He adds that Platinum's RC/Query product moreover enhances DB2's query facilities and may be employed in connection with RC/Secure to verify updated objects within user and application domains.

    Peterson anticipates a continuing require for DB2 enhancement products despite IBM's pretense that Version 6 will liquidate the necessity for certain types of enhancement products. Says Peterson, while IBM is trying to slither toward a goal of a Universal Database to enable administration across platforms, "there are differences in the mainframe DB2 product that were establish there to cater to the MVS folks and to capitalize on the characteristics of that platform that will continue to impede this goal."

    Computer Associates: Enhancement Equals Replacement

    Mark Combs agrees that IBM opened doors to third parties with version 5 of its DB2 implementation on MVS. Combs, who is Senior Vice President for Research and development with Computer Associates (CA) in Islandia, NY, sees the break created less in terms of enhancing DB2 than as an break to supersede RACF with either ACF2 or Top furtive - both CA mainframe security management products.

    "Companies necessity to slither to real, rules-based security - that is, a situation in which traffic rules determine access. Today, in many mainframe environments, about 75 percent of the rules are controlled by system management products such as CA-ACF2, CA-Top furtive or RACF from IBM. Another 25 percent are actually established or enforced using much less robust SQL database security capabilities in products like DB2. What is needed is an integrated management infrastructure that enable centralized, rules-based security across the entire environment and that provide administrative tools on the mainframe, as well as graphical user interface-based tools on the desktop," says Combs.

    Basic SQL Coding for DB2 Universal Database for OS/390 | killexams.com true questions and Pass4sure dumps

    Take a hunt at the four primary statements of DML: Select, Update, Insert, and Delete. You will learn the duty each of these can play in your efforts to master DB2. You will moreover hunt at various aspects of SQL, a necessary language to understand though the comprehension plane will vary depending on the user's activity.

    This chapter is from the reserve 

    In the previous chapter, they discussed the definitions of various database objects using the Data Definition Language (DDL). In this chapter, they start manipulating the database objects using the portion of SQL known as Data Manipulation Language (DML). They will be populating (inserting) data into the database and retrieving the data using many powerful methods. Depending on the sophistication of the database users, they can exhaust SQL to query the database. The majority of the SQL statements within a DB2 application involve DML statements. Therefore, application developers must understand the various methods of inserting, updating, and retrieving data from the database. They will start with simple retrieval statements and gradually introduce more knotty methods of data manipulation. The DB2 Certification database will be used for most of the examples. There are four main DML SQL statements they consider: SELECT, INSERT, UPDATE, and DELETE.

    SQL is based on mathematical principles, specifically on set theory and relational algebra. The data is stored in the database as unordered sets of data records. SQL is a set-oriented language, and many of its language elements are directly related to relational algebraic terms, such as permutation, projection, restriction, and join.

    A set of data is represented in a DB2 database as a table or a view and is stored in a DB2 table without regard to order. To retrieve data in a particular order, an ORDER BY phrase must be added to a SELECT statement. Similarly, if the data is to be grouped, then a GROUP BY phrase must be added to the statement.

    Now, let's review the DB2CERT database design defined in the previous chapter and exploit data using various SQL statements. There are three main tables: CANDIDATE, TEST, and TEST_CENTER. Each table represents a set of records that correspond to a test candidate (person), a test, and a test focus (location).

    There is an associative table, known as the TEST_TAKEN table, that is used to reflect the relationships among the three main tables. The TEST_TAKEN table is used to schedule the test candidates and moreover to maintain their test scores.

    NOTE

    The longest SQL statement is 32,765 bytes.

    Remember that to execute any operation, the user must hold the necessary privileges.

    Retrieving the Entire Table

    The most basic of any retrieval command involves the SELECT statement with no operators other than the name of the table. This SQL statement retrieves any of the candidates who hold taken a DB2 Certification exam. The information requested is contained in the table TEST_TAKEN.

    SELECT * FROM db2cert.test_taken

    SQL is a data access language that consists of language statements and clauses. There are many optional clauses that can be used to modify the output. The output of a SELECT statement is known as a result set or result table. The results from the SELECT statement are shown next. In this example, using an asterisk or star character (*) for column selection, the columns will be returned to the user in the order in which they are defined in the table.

    CID TCID NUMBER DATE_TAKEN START_TIME FINISH_TIME SCORE PASS_FAIL SEAT_NO --- ---- ------ ---------- ---------- ----------- ----- --------- ------- 111 TX01 500 01/01/2000 11:30:00 12:30:00 65 Y 1 111 TX01 501 02/02/2000 10:30:00 11:45:00 73 Y 1 111 TX01 502 03/03/2000 12:30:00 13:30:00 67 Y 1 222 TR01 500 01/01/2000 14:00:00 15:30:00 55 N 2 222 TR01 502 01/02/2000 09:00:00 10:15:00 53 N 2 222 TR01 502 02/18/2000 10:00:00 11:30:00 75 Y 2 333 TX01 500 03/01/2000 11:30:00 13:00:00 82 Y 2 333 TX01 501 12/29/2000 14:00:00 - - - 1 333 TX01 502 03/02/2000 14:00:00 14:30:00 92 Y 1 9 record(s) selected.

    In SQL, the * is used to indicate that any columns of a table are being referenced. In this example, the SQL statement refers to any of the columns defined for the DB2CERT.TEST_TAKEN table. If the table is altered and a original column is added to the table definition, the result set would contain the original column.

    NOTE

    Adding a original column to an existing table will result in default values being populated for the existing rows.

    Since the output of the SQL statement using * character varies according to the table definition, it is recommended that you specify any of the column names you want to survey in the SELECT statement. They could hold obtained the very result as the statement using SELECT * with the following SQL statement.

    SELECT cid, tcid, number,date_taken,start_time, finish_time,score,seat_no FROM db2cert.test_taken;

    NOTE

    The * character is used to mention to any of the columns defined for a table. The order of the columns in the result table is the very order as specified in the CREATE TABLE or CREATE VIEW statement.

    What is returned to the user is known as the result set. If the result set is large it is advisable to be sure to filter the data using a WHERE predicate.

    The FROM clause is required for the DML SQL statement, since it describes the location (table or view) of the data. Their specimen references a single table called DB2CERT.TEST_TAKEN. The SELECT and FROM clauses are required in any data retrieval statements. The list of columns following the SELECT keyword is referred to as the select list.

    Projecting Columns from a Table

    Projection is a relational operation that allows you to retrieve a subset of the defined columns from a table. The next specimen restricts the output from the SELECT command so that only the candidate ID, test center, and test number attributes from the TEST_TAKEN table are shown.

    SELECT cid,tcid,number FROM db2cert.test_taken

    The output of this SELECT statement is shown below.

    CID TCID NUMBER --- ---- ------ 111 TX01 500 111 TX01 501 111 TX01 502 222 TR01 500 222 TR01 502 222 TR01 502 333 TX01 500 333 TX01 501 333 TX01 502 9 record(s) selected.

    The order of the columns in the result table will always match the order in the select list. The order of the columns as they were defined in the CREATE TABLE or CREATE VIEW statement is ignored when a select list is provided in the SQL statement. In this example, the order of the columns is similar to the order in the CREATE TABLE statement, since the CID column was defined prior to TCID and NUMBER columns.

    Changing the Order of the Columns

    Permutation is the relational operation that allows you to change the order of the columns in your result table. Permutation is used every time you select columns in an order different than the order defined in the CREATE TABLE statement. For example, to panoply the test focus ID prior to the candidate IDs and the test number, you could execute the following:

    SELECT tcid,cid,number FROM db2cert.test_taken

    The result of this SELECT statement specifies a select list in a different order than was defined in the table definition.

    TCID CID NUMBER ---- --- ------ TX01 111 500 TX01 111 501 TX01 111 502 TR01 222 500 TR01 222 502 TR01 222 502 TX01 333 500 TX01 333 501 TX01 333 502 9 record(s) selected.

    NOTE

    We mention to the output of a SELECT statement as the result table because the output of any SELECT statements can be considered a relational table.

    Restricting Rows from a Table

    Restriction is a relational operation that will filter the resulting rows of a table. Restriction can be accomplished through the exhaust of predicates defined in a SQL WHERE clause. To restrict the result set, they necessity to add a WHERE clause to the SQL statement.

    NOTE

    A predicate is a condition placed on the data. The result of the condition is TRUE, FALSE, or UNKNOWN.

    The WHERE clause specifies conditions or predicates that must be evaluated by DB2 before the result table is returned to the conclude user. There are many valid types of predicates that can be used. In the following example, the equality (=) predicate is used to restrict the records to only those candidates who hold taken a DB2 Certification test at the test focus TR01.

    SELECT tcid,cid FROM db2cert.test_taken WHERE tcid ='TR01'

    The WHERE clause moreover accepts other comparison operators, such as greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), and not equal to (<>).This statement is an specimen of a basic predicate. A basic predicate compares two values. In addition, more knotty predicates, such as LIKE, BETWEEN, and IN, are moreover valid and will be discussed later.

    NOTE

    Trying to execute this specimen SQL statement will result in a data type compatibility error, because the column TCID is defined with a user-defined data type (UDT).

    Predicate Evaluation for UDTs

    The column TCID was defined as a user-defined data type. To do the comparison in the WHERE clause valid, a casting duty needs to be used. This is not mandatory if the comparison is to a literal or host variable. This technique is however demonstrated below:

    SELECT tcid, cid FROM db2cert.test_taken WHERE tcid=CAST('TR01' AS db2cert.center_id)

    Predicate evaluation requires that the data types be compatible (same data type or a compatible data type). They can accomplish the data type conversion (cast) using one of two methods:

  • Use the CAST expression.
  • Use a casting function.
  • Refer to Chapter 15, "Object Relational Programming," for more information on casting for UDTs.

    NOTE

    Although not always mandatory, casting is recommended to ensure compatible data types are compared, including length and scale. This allows DB2 to resolve these as indexable rather than stage 2 predicates.

    Restricting Rows Using Multiple Conditions

    It is possible to combine multiple conditions (predicates) in a single SQL statement. The predicates can be combined using Boolean operators, such as the AND or OR operators. These operators allow you to combine multiple conditions in a single SQL statement. The order of the predicate evaluation will not touch the result set (known as set closure).

    The next specimen retrieves the records for the test candidates who took a test at test focus TR01 and achieved a score greater than 65. The rows that satisfy the predicates are known as the qualifying rows. The following specimen is an SQL statement using multiple predicates:

    SELECT tcid,cid,score FROM db2cert.test_taken WHERE tcid= CAST('TR01' AS db2cert.center_id) AND score > 65 Selecting Columns from Multiple Tables

    There are basically two operations that combine columns from multiple tables in a single SQL statement. These operations are

    Cartesian Product

    A Cartesian product is a relational operation that will merge any the values from one table with any the values from another table. This operation is not used frequently because the result table can be very large. The number of rows in the result table is always equal to the product of the number of rows in the qualifying rows for each of the tables being accessed.

    NOTE

    The DB2 optimizer may elect to utilize a Cartesian product of unrelated tables if this is deemed to be an efficient manner of accessing multiple tables. An specimen would be two single-row tables that are joined with a large table. The cross-product of 1 ∴ 1 = 1; thus the large table access is deferred as late as possible, with a potential enlarge in the restrictive predicates that can be applied without incurring the overhead of a large Cartesian result. This manner of table access is typical in processing queries against a star schema data model.

    The following specimen is a Cartesian product of any test numbers and test names from the TEST table, with any candidates from the TEST_TAKEN table. First, select from the TEST table.

    SELECT number, name FROM db2cert.test NUMBER NAME ------ -------------------------------------------------- 500 DB2 Fundamentals 501 DB2 Administration 502 DB2 Application Development 3 record(s) selected. Next select of any candidates from the test_taken table. SELECT cid,tcid FROM db2cert.test_taken CID TCID --- ---- 222 TR01 222 TR01 222 TR01 111 TX01 111 TX01 111 TX01 333 TX01 333 TX01 333 TX01 9 record(s) selected.

    Then combine the two tables to figure a Cartesian product result table.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test NUMBER CID TCID ------ --- ---- 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 500 111 TX01 501 111 TX01 502 111 TX01 500 222 TR01 502 222 TR01 502 222 TR01 500 333 TX01 501 333 TX01 502 333 TX01 27 record(s) selected.

    There are two tables referenced in the FROM clause of this query. The tables are separated by commas. There is no relationship expression in the WHERE clause. This type of query results in a Cartesian product.

    The result table is a representation of any possible combinations of the input tables. The TEST table has three rows, and the TEST_TAKEN table has nine rows. Therefore, the SELECT statement shown above returns 27 rows. Note the first column name in this query. It is necessary to fully qualify the column name by providing the schema name and table name with the column name because this column exists in both the TEST table and TEST_TAKEN table. In this case, they needed to specify that the NUMBER column is to be retrieved from the DB2CERT.TEST_TAKEN table and not from the DB2CERT.TEST table.

    By adding a predicate to a Cartesian product SQL query, the result table can limn a more useful representation of the data. In the specimen below, the query represents any of the tests that were taken by the candidate whose ID is 111.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test WHERE cid='111' NUMBER CID TCID ------ --- ---- 500 111 TX01 500 111 TX01 500 111 TX01 501 111 TX01 501 111 TX01 501 111 TX01 502 111 TX01 502 111 TX01 502 111 TX01 9 record(s) selected.

    Adding a WHERE clause to your query does not always provide the desired result. In the specimen shown above, you want to know any of the tests that were taken by the candidate whose ID is 111, and the query returns nine rows. But they know from previous queries that the candidate took only three tests. The query in the specimen above has a WHERE clause to filter out the candidate whose ID is 111 from the TEST_TAKEN table, but there was no filter on the TEST_CENTER table. Therefore, the result of the query would always be a multiple of the number of testing centers. Usually, when multiple tables are referenced, you should embrace a cross-table relationship using a table merge or combine method, as shown in the following example. They will examine table combine methods further in the next section.

    SELECT db2cert.test_taken.number,cid,tcid FROM db2cert.test_taken,db2cert.test WHERE cid= '111' AND db2cert.test_taken.number=db2cert.test.number NUMBER CID TCID ------ --- ---- 500 111 TX01 501 111 TX01 502 111 TX01 3 record(s) selected.

    To avoid data redundancy, it is recommended that the database tables be normalized. Following a normalization process, a number of related tables will exist. To satisfy some of the required queries, the tables must be reconstructed. The tables are reconstructed temporarily, using a table combine strategy to yield a single-result table.

    The result tables in the previous examples usually provided candidate ID numbers and not the complete name of the test candidates. The candidate IDs are stored in the TEST_TAKEN table, and the replete names are stored in the CANDIDATE table. To obtain the name of a candidate, the data must be retrieved from the CANDIDATE table, using a relationship or combine strategy.

    Consider an specimen that will list the names and phone numbers of candidates who were registered to engage a DB2 Certification test in 2000. To accomplish this, they necessity to select data from two different tables:

  • db2cert.candidate
  • db2cert.test_taken
  • Let's retrieve a list of candidate names, phone numbers, and IDs from the CANDIDATE table. The candidate names were stored in multiple columns to allow for effortless retrieval by eventual name.

    SELECT fname,initial,lname,hphone,cid FROM db2cert.candidate

    The output of this specimen follows. Pay special attention to the values in the CID column. It will be used as the combine column in the next example.

    FNAME INITIAL LNAME HPHONE CID -------- ------- ---------- ---------- --- Bill B Wong 1115551234 111 George Baklarz 2226543455 222 Susan M Visser 4442314244 333 Glen R Sheffield 5552143244 444 Jim G Stittle 6662341234 555 Kevin W Street 7773142134 666 Bert F Nicol 8886534534 777 Paul C Zikopoulos 9992112212 888 8 record(s) selected.

    Now, let's retrieve the ID numbers of those candidates who were registered to engage the test in 2000.

    SELECT separate cid FROM db2cert.test_taken WHERE YEAR(date_taken) = 2000 CID --- 222 111 333 3 record(s) selected.

    The candidate IDs in the TEST_TAKEN table must correspond to a candidate ID in the CANDIDATE table because of the declarative referential integrity constraints. The parent table in the relationship is the CANDIDATE table and the child table (dependent table) is the TEST_TAKEN table.

    The result table from the above query does not embrace the test candidate 444, since that candidate did not hold a test scheduled for 2000. They necessity to combine the two result tables based on the candidate ID values. This column is known as the combine column.

    NOTE

    Query performance can significantly better if the combine columns are appropriately indexed.

    The following single query will satisfy the end-user requirement.

    SELECT separate fname,initial,lname,hphone FROM db2cert.test_taken,db2cert.candidate WHERE YEAR(date_taken) = 2000 AND db2cert.test_taken.cid=db2cert.candidate.cid

    A table combine requires a predicate that includes an expression based on columns from the tables referenced in the FROM clause. This is known as a combine predicate. The FROM clause has not changed from the Cartesian product examples. The only inequity is in the combine predicate (test_taken.cid = candidate.cid).

    NOTE

    An alternative figure of the FROM clause for joins involves explicitly coding the combine keyword between the tables (rather than using a comma) and coding the combine predicates in the ON clause rather than in the WHERE clause. This manner of coding will be covered in more detail in Chapter 4, "Advanced SQL Coding."

    The table names needed to be explicitly stated because there is a column named CID in both of the referenced tables. When multiple tables are being accessed in a single query, any selected columns that occur in more than one table must be qualified with the table name.

    NOTE

    An mistake will occur if the columns being referenced are obscure (not properly qualified).

    The maximum number of base tables that can be in a single SQL statement is 225; however, you are limited to 15 tables in a combine (the FROM clause).

    NOTE

    The 15-table restrict can be increased by updating the macro SPRMMXT to a value greater than 15.

    This kindly of combine operation shown in the above specimen is moreover known as an inner join. An inner combine displays only the rows that are present in both of the joined tables.

    Using Correlation Names

    If each of the columns needed to be fully qualified with the table name, such as tableschema.tablename.columnname, the queries would become very large and cumbersome to work with. Fortunately, there is an easier way to qualify the obscure columns resulting from a multitable SELECT statement.

    The columns can be qualified using a correlation name. A correlation name is a temporary alias for the tables referenced in an SQL statement. They rewrite the previous query using correlated names as follows:

    SELECT separate fname,initial,lname,hphone FROM db2cert.test_taken tt, db2cert.candidate c WHERE YEAR(date_taken) = 2000 AND tt.cid = c.cid

    The correlation name immediately follows the name of the table as stated in the FROM clause. In this example, the correlated name for the TEST_TAKEN table is tt, and the correlated name for the CANDIDATE table is c.

    NOTE

    Correlation names can be optionally prefixed with the AS keyword, such as DB2CERT.CANDITATE AS C. This is purely for readability.

    The correlated names are accessible within the SQL statement only. Following the execution of the SQL statement, the correlation name is no longer defined. Once a correlation name has been defined, it can be referenced in the rest of the query instead of the table name. However, the table name can still be referenced.

    NOTE

    Use simple, easy-to-remember correlation names. Table initials are fine candidates for correlation names.

    Sorting Your Output

    We hold been retrieving data from one or more tables. The order of the result table has not been specified in any of the SQL statements. Therefore, the data is retrieved in an undetermined order if there is no ORDER BY clause in the SQL statement.

    NOTE

    The only guaranteed way to revert data in the required sequence is with the ORDER BY clause. Any data retrieval that is currently returned in sequence without this clause is purely based upon the data retrieval manner at the time. A future access path change may not revert the data in the very sequence.

    The following specimen produces a list of the test candidates in alphabetical order by eventual name for the candidates who hold taken a DB2 Certification test at the TR01 test center.

    SELECT lname,initial,fname FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid='TR01' ORDER BY lname

    This specimen contains a original clause, ORDER BY. After the ORDER BY clause, you can list the columns that will specify the sort order and the type of sort.

    NOTE

    Appropriate indexing may allow DB2 to avoid sorting the data to match the ORDER BY clause. If the data is already sequenced via the index, DB2 may elect to utilize the index and avoid sorting the data. DB2 cannot avoid a sort for an ORDER BY involving columns from more than one table. Where possible, embrace columns from only one table in the ORDER BY to give DB2 greater break for sort avoidance.

    The SQL can be modified so that the output is changed to descending order by eventual name and a secondary order column on the first name in ascending order.

    SELECT lname,fname,hphone FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid= 'TR01' ORDER BY lname DESC, fname

    In this example, the DESC keyword that follows the lname column indicates that the result table should be in descending order based on the eventual name. More than one record can hold the very eventual name. This situation is quite common. There is a second column specified in the ORDER BY clause, fname. There is no keyword specifying the sort sequence based on the fname column. Therefore, the default ordering sequence (ascending) is used.

    The next specimen contains three columns lname, fname, and hphone. You can reference the column that should be used to sort the data using the column name or by specifying its position in the select list. Using the column position is useful when the column in the select list is made up of derived columns (calculated columns) that hold no categorical name.

    SELECT lname,fname,hphone FROM db2cert.candidate c,db2cert.test_taken tt WHERE c.cid=tt.cid AND tcid='TR01' ORDER BY 1 DESC, 2

    In this example, the sort order is specified using the column position. Therefore, the query result is exactly the very as the in previous example.

    You can moreover allot an alternative column name using column renaming. The assigned name can then be referenced in the ORDER BY clause, and it appears as the column heading where appropriate.

    NOTE

    Although useful, coding a column position rather than a column (or renamed column) in the ORDER BY clause may lead to a different sequence if another column is inadvertently added to the query that alters the column positioning.

    The ORDER BY clause must succeed any subselects in the FULLSELECT statement. The only clauses that can succeed the ORDER BY clause are the for FOR FETCH ONLY, FOR READ ONLY, OPTIMIZE, WITH QUERYNO, FETCH FIRST n ROWS clauses.

    Derived Columns

    There are some cases when you will necessity to perform calculations on the data. The SQL language has some basic mathematical and string functions built in. Mathematical operations embrace standard addition, subtraction, multiplication, and division.

    The calculation can be defined in the WHERE clause of the SQL statement or the select list. Suppose that you necessity to calculate a passing rate for a DB2 test. The passing rate is defined as the percentage of candidates that pass the test (totalpassed*100/totaltaken). The following SQL statement will accomplish this for us for test number 500:

    SELECT number, totalpassed*100/totaltaken FROM test WHERE number='500'

    In this example, the second column of the output list is a calculated column. recall that you must exhaust the column position if you want to exhaust this calculated column for the ORDER BY clause unless you name it (as they now discuss).

    NOTE

    Occasionally, the results of a derived column may not panoply as expected. The specimen using totalpassed*100/totaltaken will result in a value of 66 being retrieved. Since both the totalpassed and totaltaken columns are integers, the final result is moreover an integer, and the fractional allotment is discarded. If this is not your desired result, you should exhaust other functions (like decimal) to change the way the calculation is performed or displayed.

    Naming Derived/Calculated Columns

    You can specify a column name for any expression. When you provide the derived (calculated) column with a name, the ORDER BY clause can reference the derived name to allow for a more readable SQL statement.

    The following SQL calculates the percentage of people that hold passed the DB2 Certification exams and orders the output in descending order of the passing rate.

    SELECT number,totalpassed*100/totaltaken AS PassedRate FROM test ORDER BY PassedRate DESC

    The AS clause is used to rename the default name of an factor in the select list. In this example, they are giving the name of PassedRate to the result of the division of columns totalpassed by totaltaken. The named column is used in the query to specify the column that should be used for sorting the output.

    NOTE

    The AS keyword is optional, although it should be added for readability. Without the AS clause, it may be unclear whether the aim was to rename a column or a comma was missed between two retrieved columns.

    Functions

    In DB2, there are different types of functions provided. For example, two types of functions provided by DB2 are scalar and column functions (a third type of duty called a table duty is discussed in Chapter 15, "Object Relational Programming."

  • Scalar functions (also known as row functions) provide a result for each row of the result table. A scalar duty can be used any position an expression is allowed.

  • Column functions (also known as vector functions) work with a group of rows to provide a result. The group is specified using a FULLSELECT and optionally grouped using the GROUP BY clause.

  • In this section, they introduce you to some of the SQL functions provided with DB2. SQL functions are categorized by their implementation type. Either the functions are built in or they are extensions of DB2 and are known as user-defined functions (UDFs).

  • Built-in functions are defined within the SQL standards, and they are provided by DB2. These can be either scalar or column functions.

  • UDFs are not defined within the SQL standards because they are extensions of the current SQL language. These functions can be developed by a DB2 administrator or application developer. UDFs can be either scalar or table functions, but not column functions. Once the UDFs hold been created, they can be invoked by any conclude user with the proper privileges. For more information about UDFs, mention to Chapter 15.

  • Scalar Functions

    Scalar functions are applied to each row of data, and there is a per-row result provided. If they want to retrieve only the first three digits of telephone numbers for each candidate, they could exhaust a scalar function. The duty that is used is called SUBSTR. The arguments for this duty embrace a string data type column, a nascence offset, and length. The output data type and credit of the duty depend on the input data type and attribute. The following specimen retrieves the telephone zone code for the column wphone.

    SELECT lname, SUBSTR(CHAR(wphone),1,3) FROM db2cert.candidate

    The SUBSTR duty is a scalar function. In this example, SUBSTR returns a character string of three characters. The result string corresponds to the first three characters of the wphone column. This duty is known as a string duty because it works with any string data type. If they wanted to provide the output column with a meaningful name, they could provide an alias, as was done for calculated columns.

    In the specimen above, the substring starts from the nascence of the string, because they indicate one (1) as the second parameter of the function. The length of the resulting string is indicated in the third argument. In their example, the length is three. Note that the data type of the wphone column is phone, so a casting duty is used to metamorphose the phone data type to the char data type.

    The following query will provide the month when the exam was taken. The input for this duty is a DATE string, and the output is an integer.

    SELECT fname, MONTH (date_taken) FROM candidate c, test_taken tt WHERE c.cid=tt.cid Column Functions

    Column functions provide a single result for a group of qualifying rows for a specified table or view. Many common queries can be satisfied using column functions where they embrace common tasks, such as finding the smallest value, the largest value, or the mediocre value for a group of data records. In the following specimen you can obtain the maximum length of time of any of the DB2 Certification exams:

    SELECT MAX("length") FROM test

    Because the length column shares its name with the length scalar function, the column name is encased within double-quotes to distinguish this as a column and not a function.

    If they added a WHERE clause to this example, the maximum would limn the maximum length for the qualifying rows, since the predicate is used to filter the data prior to the application of the MAX function.

    This next specimen calculates the mediocre of the number of seats for any of the test centers. Notice the column duty AVG is used in this example:

    SELECT AVG(noseats) FROM test_center

    DB2 provides many more built-in functions. If you are interested in calculating statistical information, you can exhaust statistical functions, such as VARIANCE, STDDEV, or a sampling of these functions.

    NOTE

    MAX and MIN functions can be either column or scalar functions depending on the input arguments.

    Grouping Values

    Many queries require some plane of aggregated data. This is accomplished in SQL through the exhaust of the GROUP BY clause. The following SQL obtains the mediocre number of seats for each country:

    SELECT country, AVG(noseats) FROM test_center GROUP BY country

    This SQL statement obtains the mediocre number of seats per country, and the GROUP BY clause tells DB2 to group together the rows that hold the very values in the columns indicated in the GROUP BY list. In their example, they are grouping countries into subsets. As the subsets are created, DB2 calculates the mediocre of each of those groups or subsets, in this case, by each country.

    When you combine column functions and other elements, such as column names, scalar functions, or calculated columns, you must exhaust the GROUP BY clause. In this case, you must embrace every factor that is not a column duty in the GROUP BY list. The only elements that can be omitted in the GROUP BY list are constant values.

    The next SQL statement obtains a list that includes the mediocre slash score and minimum test length for the DB2 Certification exams. They group this list by the type of exam, as follows:

    SELECT type, AVG(cut_score), MIN("length") FROM test GROUP BY type

    NOTE

    Appropriate indexing can allow DB2 to avoid a sort to group the data rows to match the GROUP BY clause.

    It is possible to sort the output of the previous specimen using an ORDER BY clause.

    NOTE

    GROUP BY may revert data in the very order as an ORDER BY, but this is not guaranteed and is based upon the access path. The only manner to guarantee data sequence is with an ORDER BY.

    Restricting the exhaust of Sets of Data

    Up to now, they hold discussed how to restrict output based on row conditions. With SQL, it is moreover possible to restrict that output using column functions and the GROUP BY clause. Suppose you want a list of any the test centers that hold administered more than five DB2 Certification exams. To do it easier to understand, let's first net the number of tests that hold been taken in each test center.

    SELECT tcid, count(*) FROM test_taken GROUP BY tcid

    We exhaust the signify column duty to net the total number of tests that hold been taken in each test center. When you exhaust an asterisk (*) with the signify function, you are indicating that you want the number of rows in a table that meet the criteria established in the SQL statement. In this example, they are grouping by TCID because they hold a number of occurrences for any the test centers in the TEST_TAKEN table. The TEST_TAKEN table has an entry for every DB2 Certification exam that has been taken. Finally, the output is restricted to only those test centers that hold administered more than four exams.

    SELECT tcid FROM test_taken GROUP BY tcid HAVING COUNT(*) > 4

    This specimen introduces the HAVING clause. The HAVING clause is equivalent to the WHERE clause for groups and column functions. The HAVING clause will restrict the result set to only the groups that meet the condition specified in it. In their example, only the test centers that hold administered more than four DB2 Certification exams will be displayed.

    Eliminating Duplicates

    When you execute a query, you might net duplicate rows in the reply set. The SQL language provides a special clause to remove the duplicate rows from your output. The following SQL generates a list of names and phone numbers for any the candidates who hold taken a test. In the following example, they liquidate the duplicate rows from their output list using the separate clause.

    SELECT separate fname,wphone,hphone FROM candidate c,test_taken tt WHERE c.cid=tt.cid

    The separate clause can moreover be used with the signify function. When you exhaust separate inside a signify function, it will not signify the duplicate entries for a particular column. The following specimen allows you to signify how many different test centers hold candidates registered.

    SELECT COUNT(DISTINCT tcid) FROM test_taken

    This specimen provides the number of test centers that are registered in the TEST_TAKEN table. recall that any the candidates who hold registered for DB2 Certification exams are stored in this table. do sure that you understand the inequity between COUNT(*), COUNT(colname), and COUNT(DISTINCT colname). They are very similar in syntax but differ in function.

    NOTE

    COUNT(*) returns a signify of any rows that qualify against the WHERE clause. COUNT(colname) returns a signify of any rows that qualify against the WHERE clause, with null occurrences of colname removed. COUNT(DISTINCT colname) counts separate occurrences of colname, with nulls removed.

    Searching for String Patterns

    SQL has a powerful predicate that allows you to search for patterns in character string columns. This is the like predicate. Suppose you want to generate a list of the candidates whose first name starts with the epistle G.

    SELECT fname,lname,wphone,hphone FROM candidate WHERE fname like 'G%' ORDER BY lname,fname

    In this query, they exhaust a wildcard character with the like predicate. In SQL, the percent character (%) is a substitute for zero or more characters. The search string G% can be substituted with names like George, Gary, Ginger, and so on (since the percent character can substitute zero or more characters, the search string can moreover be a single epistle G).

    The percent character can be used any position in the search string. It moreover can be used as many times as you necessity it. The percent sign is not case-sensitive, so it can engage the position of uppercase or lowercase letters. However, the constant characters included in your search string are case-sensitive.

    Another wildcard character used with the like predicate is the underline character (_). This character substitutes one and only one character. The underline character can engage the position of any character. However, the underline character cannot be substituted for an barren character.

    NOTE

    If the pattern needs to search for occurrences of the wildcard characters % and _ as their actual values, then the shun clause is used to specify a character that precedes the percent or underscore in the pattern.

    The previous SQL can be modified to embrace any candidates' names and the telephone numbers for those candidates whose name has a lowercase epistle "a" as its second letter.

    SELECT fname,lname,wphone,hphone FROM candidate WHERE fname like '_a%' ORDER BY lname,fname

    This specimen uses two wildcard characters that work with the like predicate. The search string in this specimen can embrace names, such as Paul, Gabriel, or Natalie. (The first character may be any character, the lowercase epistle "a" is the second character in the string, and the string ends with any number of characters.)

    NOTE

    When the pattern in a like predicate is a fixed-length host variable, the amend length must be specified for the string to be returned. 'G%' assigned to an 8-byte variable (LIKE :variable) will search for any occurrences of 'G% ' (G, followed by any character, followed by 6 blank characters). To find rows that start with a G, then 'G%%%%%%%' should be assigned to the fixed-length variable.

    Searching for Data in Ranges

    SQL moreover offers us a ambit operator. This operator is used to restrict rows that are in a particular ambit of values. reckon the requirement to list those candidates whose scores in the DB2 Certification exam are between 60 and 75.

    SELECT separate fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score BETWEEN 60 AND 75

    The BETWEEN predicate includes the values that you specify for searching your data. An faultfinding fact about the BETWEEN predicate is that it can work with character ranges as well.

    In addition to the score requirement, this specimen modifies the SQL to embrace only those candidates whose eventual name begins with a epistle between B and G.

    SELECT separate fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score BETWEEN 60 AND 75 AND lname BETWEEN 'B' AND 'GZ'

    In this example, the second BETWEEN predicate contains character values. They necessity to specify the GZ value to embrace any the possible names that start with the epistle G. This was done assuming that the epistle Z is the eventual possible value in the alphabet.

    NOTE

    The arguments of the BETWEEN clause are not interchangeable; the first must specify the low value, and the second, the lofty value. BETWEEN 1 AND 2 will revert any values within the ambit (inclusive of 1 and 2). BETWEEN 2 AND 1 will revert zero rows.

    Searching for Null Values

    Null values limn an unknown value for a particular incident of an entity. They can exhaust a null value in the cases where they don't know a particular value of a column. Let's Tell that they want a list of any those candidates whose score is not yet input. This condition is represented with a null value.

    SELECT fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND score IS NULL

    The IS predicate is used to search for the null value in this example. recall that the null value means "unknown." Because it has no particular value, it can't be compared with other values. You can't exhaust conditional operands, such as equal (=) or greater than (>), with null values.

    Searching for Negative Conditions

    The BETWEEN, IS, and like predicates always hunt for the values that meet a particular condition. These predicates can moreover be used to hunt for values that don't meet a particular criterion.

    The NOT predicate can be used to hunt for the opposite condition, combined with the LIKE, BETWEEN, and IS predicate, to accomplish negative searches, as shown in the following example. This specimen has a like predicate combined with the NOT predicate. They want a list of those candidates whose eventual names execute not start with the epistle S.

    SELECT separate fname,lname,wphone,hphone FROM candidate WHERE lname NOT like 'S%' ORDER BY lname,fname

    The next specimen has a BETWEEN predicate combined with the NOT predicate. They want the list of those candidates whose score, in any test, is not in the ambit 60 to 75.

    SELECT separate fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND integer(score) NOT BETWEEN 60 and 75

    In this example, the NOT predicate will exclude any the values that are in the ambit 60 to 75.

    Negation can moreover be applied to the null value. This SQL produces a report that searches for those candidates that hold a seat number assigned. This is expressed with a NOT NULL value.

    SELECT separate fname,lname,wphone,hphone FROM candidate c, test_taken tt WHERE c.cid=tt.cid AND seat_no IS NOT NULL

    NOTE

    The NOT operator can moreover be used to negate the standard comparison operators, =, <, <=, >, and >=.

    When dealing with nulls, NOT or negation may not revert the opposite of the positive logic. For example, WHERE SEAT_NO = 1 will revert only the rows for seat number 1. Any value other than 1 is discarded, as these rows are FALSE, including nulls, since these are unknown. WHERE SEAT_NO <> 1 excludes rows where the seat number is 1, and moreover discards nulls because these are unknown.

    Searching for a Set of Values

    In SQL, it is possible to establish a restriction condition based on a set of values. Suppose that you necessity a list of the test centers that hold candidates registered for the DB2 Fundamentals test and for the DB2 Application development test. This can be queried with the following statement:

    SELECT separate name,phone FROM test_center tc, test_taken tt WHERE tc.tcid=tt.tcid AND (number = '500' or number ='502')

    To simplify structure multiple OR conditions when multiple values for the very column are being compared, it is possible to rewrite the statement using the IN clause.

    SELECT separate name,phone FROM test_center tc, test_taken tt WHERE tc.tcid=tt.tcid AND number IN ('500','502')

    The IN clause is used to denote a set of values. In this example, they exhaust a constant set of values.
