Answer / tej
Precompilation separates the SQL statements and non-SQL
statements of an application program.
From the precompilation step onwards the original source
code will be contained in two separate physical components.
The non-sql part of the program will have all the
sql-statements commented out by the precompiler and and
replaced with cobol call statements.
The colection of SQL that was extracted will be placed in a
DBRM(Database Request Module).Precompiler also places a
consitency token in both of its outputs.

Answer / yuvaevergreen
Precompiling does the following:
>> Replaces the SQL statements in your source programs with
calls to DB2 language interface modules.
>>Creates a database request module (DBRM), which
communicates your SQL requests to DB2 during the bind
process

COBOL+DB2 COMPILATION PROCESS:-
1)PRE-COMPILATION :-
*PRE-COMPILATION PROCESS UTILITY IS DSNHPC
*IT IS THE PROCESS OF SEPARATING COBOL AND DB2 STATEMENTS
*IT CHECK THE SYNTAX ERRORS OF DB2 STATEMENTS AND ALSO IT PLACES THE ERROR FREE DB2 STATEMENTS IN DBRM
*AND ALSO IT PLACES THE TIME-STAMPS TOKEN IN MODIFIED SOURCECODE AND DBRM
*********MODIFIED SOURCE CODE:-IT PLACES ONLY COBOL CALL STATEMENTS...ALL DB2 STATEMENTS REPLACED BY THE COBOL CALL STATEMENTS*******
********DBRM(DATA BASE REQUEST MOODULE)..ONE DBRM IS CREATED FOR ONE PROGRAM***********

Hi i need to write a query on the following requirement. SELECT COMM_TEXT INTO :WS_MIKM_COMM_TEXT FROM MPIPROD.MIKMV01 WHERE ACCOUNT_NO = :WFD_ACCOUNT_NO AND (SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT AND SUBSTR(COMM_TEXT,47,14) = :WS_DENY_DESC) OR (SUBSTR(COMM_TEXT,1,39) = :WS_COMMENT_TEXT) The above query is to be modified. The requirement is if both the fields are equal then that has to be given priority. In the above query if it satisfies any one it comes out without checking if both being equal is possible.
