Exception Handling in Stored procedures for DB2 manu_701 asked Jun 20, 2006 | Replies (2) Hello All, I am new to DB2 and just trying to get familiar with it. I have a situation in which i need to kickoff the sql statements on to db2 database and capture the return codes fromt the sql statements. if the return code is greater than 3, then i need to bomb the entire process. To implement this logic, i have created a procedure to accept the sql statement as input parms and fire it on db2. create procedure ab_proc_dyn(in stmt varchar(255)) dynamic result sets 1 language sql begin execute immediate stmt; end I am sorta stuck implementing the error handling logic for the above stored procedure.

Vijay That should do it: DECLARE CONTINUE HANDLER FOR stored procedure error SQLWARNING, SQLEXCEPTION, NOT FOUND .... Keep me on record for saying that this is a really bad idea. Cheers Serge -- Serge Rielau DB2 SQL Compiler Development IBM Toronto Lab Nov 12 '05 #2 P: n/a amurchis I have to agree with Serge here. For instance, if your procedure gets a -1224 SQLCODE (no database agent -- typically meaning your connection has been forced), coding up a continue handler, especially if you're processing result data inside the procedure, can mean your procedure will loop forever. The negative offshoot of that is that at best you'll have an db2fmp process orphaned on your system (for any FENCED procedure) or at worst the agent won't be able to be forced off as control is inside the procedure (for any NOT FENCED LANGUAGE C procedure, or SQL procedures created pre-V82 ie FP7).

You get to see as many links and Pdf's online,but most of them do not cover procedures in DB2. I take this opportunity to share some of the simplest ones,that helps a fresher to understand how to create/execute procedures/functions. Lets start with a simple stored procedure and understand how to create one,execute one. I have created a sample table by name emp_tab to illustrate the examples. Column Type Type name schema name Length Scale Nulls ------------------------------ --------- ------------------ -------- ----- ------ EMPID SYSIBM INTEGER 4 0 No EMPNAME SYSIBM VARCHAR 30 0 Yes Example 1 : Sample Stored Procedure with out parameters in it CREATE OR REPLACE PROCEDURE PROC_SAMPLE1() BEGIN INSERT INTO EMP_TAB VALUES(121,'SCOTT'); END NOTE: Before you even try to compile the stored procedure, Please do make sure you change the default delimiter to any special character other than semicolon ';' Once compiled, You can go ahead run the procedure PROC_SAMPLE1() using the below command. CALL PROC_SAMPLE1() ------------------------------------------------------------------------------ CALL PROC_SAMPLE1() output as follows: Return Status = 0 ------------------------------ Commands Entered -------------------------- SELECT * FROM EMP_TAB ------------------------------------------------------------------------------ output as follows: EMPID EMPNAME ----------- ------------------------------ 121 SCOTT 1 record(s) selected. SELECT * FROM EMP_TAB ------------------------------------------------------------------------------------------------------------ Example 2:Sample Stored Procedure with input parameters in it Now lets create a stored procedure that has parameters in it.Example 2 illustrates a stored procedure having an input parameter.
