Easytrieve Plus / DB2Course vs Dynamic Definitions and Data Communications Supported A - SQLCA Generated FieldsEasytrieve Plus /DB2Information Systems Training ISEasytrieve Plus /DB2Information Systems TrainingISCourse Pre-requisitesThis course provides no training in Easytrieve Plus nor in the use of DB2 and SQL.These topicsshould all be studied separately prior to this course.SQL (Structured Query Language) provides the method of access to DB2 data structures andremains the same no matter what application language or operating system is used.It is perfectlyreasonable to study DB2/SQL in a COBOL II environment before looking at its use in EasytrievePlus.Easytrieve Plus /DB2Information Systems Training Page 1ISStatic SQL and Dynamic SQLSQL is designed to allow specification of what data is required rather than how to access it.Theaccess paths to the data is worked out by DB2.

This may happen at two points in time:When the SQL statement is actually executed while the program is running (Dynamic SQL)In advance by using the SQL pre-processor on the source code (Static SQL)The Easytrieve Plus interface uses the Dynamic and Extended Dynamic interfaces supplied by IBM.The latter of these implements Static SQL commands.Only commands which can be executed usingthe Dynamic and Extended Dynamic interfaces can be embedded in an Easytrieve Plus program.NB.In Information Systems (BTC), programs may be run dynamically while in development, butmust be handed over to run statically in the live environment.Dynamic SQLTo run an Easytrieve Plus / DB2 program dynamically, simply use the

EZPGO catalogueprocedure to compile and run it all in one step.Easytrieve Plus /DB2Page 2Information Systems TrainingISStatic SQLBefore an Easytrieve Plus / DB2 program can be run using static SQL, it is first necessary to code aPARM LINK statement at the top of the program.The syntax of this is as follows:PARM LINK (program name [R]) +PLAN (plan name) +BIND (STATIC-ONLY)The R is short for replace, and causes an existing load module of the same name to be over-written.For the first compile of a program, the R can be left off, as the default is ADD.The program name and plan name MUST be different from one another.To run an Easytrieve Plus / DB2 program statically, it is necessary to use three separate catalogueprocedures.

The first step uses

DB2EZP to separate the program into its Easytrieve Plus and SQLcomponents.

This step produces an Easytrieve Plus load module, which is given the program name,and a Database Request Module (DBRM), which resides as a member in the partitioned datasetDEV@@xx.DB2.DBRMLIB.Also produced, but invisible to the developer, is an Assemblermodule, which is called dynamically at runtime to execute the SQL.

The second step of the process uses the Boots catalogue procedure DB2BIND to produce aPLAN from the DBRM.The PLAN is given the same name as the DBRM.Finally, the catalogued procedure TESTEZP is used to run the program.These steps are illustrated on the diagram overleaf.Easytrieve Plus /DB2Information Systems Training Page 3ISThe stages in running an Easytrieve Plus / DB2 program under static SQL.Easytrieve Plus /DB2Page 4Information Systems TrainingISEZY +LOAD MODULETESTEZP catprocDB2EZP catprocLoad Library =DEV@@xx.TEST.LOADLIBDBRM Library =Database Request ModuleAssembler ModuleSame name as DBRMDB2BIND catprocField Definitions and Data TypesAny data to be retrieved by Easytrieve Plus must be defined in the Library Section of the EasytrievePlus program.Such fields are called Host Variables.

They can either be working storage fields orfields in an active file.Host Variables are immediately preceded by a colon when they are referredto in an SQL statement.The following table shows SQL data types and their corresponding Easytrieve Plus field definitions:SQL data typeEasytrieve Plus field definitionINTEGER4 B 0SMALLINT2 B 0FLOATDECIMAL (precision, scale)x P y1CHAR (length)x AVARCHARLONG VARCHARnoneGRAPHIC (length)noneLONG VARGRAPHICnoneNUL indicator variables2 B 0nonex N ynonex B y2x U y

SQL does not support packed fields with a length greater than 8.2 SQL does not support binary fields other than 2 B 0 and 4 B 0.Easytrieve Plus /DB2Information Systems Training Page 5ISAutomatic and Controlled ProcessingA DB2 table can be accessed from an Easytrieve Plus program in one of two ways:Automatic ProcessingAll Easytrieve Plus programs must begin with a command such as FILE, PARM or DEFINE.Where there is no file input

- and therefore no FILE statement - it is necessary to code thecommand

DEFINE in front of the field definitions in the program.This statement is otherwiseoptional and would normally be left out.To specify that the job will have automatic input from SQL, it is first necessary to code the jobstatement as follows:JOB INPUT SQLA SELECT statement must then immediately follow the JOB statement.

The SELECT statementwill identify the rows and columns to be used as input to the job activity.NB.Only one SELECT

statement can be coded in each job activity.Using this method it is possible to retrieve selected data from every row within a DB2 select the contents of the column EMPNAME from the table PERSONNEL, one at a time,

using automatic input in Easytrieve Plus, code the following:DEFINE EMP-NAMEW 5 AJOB INPUT SQL SELECT EMPNAME +FROM PERSONNEL +INTO :EMP-NAME....

followed by other Easytrieve Plus commandsEasytrieve Plus /DB2Page 6Information Systems TrainingISControlled ProcessingAs with Automatic input, it is necessary to use the Easytrieve Plus DEFINE command on the firstline of the program if there is no input file.If controlled input is being used in an Easytrieve plus program, it is then necessary to define a cursorin the Library section.This is done using the SQL DECLARE statement, followed by a cursorname
