Display line number where error occurred in DB2 stored procedure

Question

I have added an EXIT handler in my procedure that captures the SQLSTATE and SQLCODE, and even found a way to get the procedure name, but I also need to know where the error occurred. Suggestions greatly appreciated.

declare EXIT handler for SQLEXCEPTION
begin
    select sysibm.routine_specific_name, SQLSTATE, SQLCODE 
    into v_sp_name, v_sqlstate, v_sqlcode 
    from sysibm.sysdummy1;

    call dbms_output.put_line('Error in '||v_sp_name ' ['||v_sqlstate, v_sqlcode||']');
end;

Answer 1

If you are on a currently supported version of Db2 for LUW (11.1 or 11.5) you can use either DBMS_UTILITY.FORMAT_CALL_STACK() or DBMS_UTILITY.FORMAT_ERROR_BACKTRACE() in your signal handler to log the troubleshooting information.

Answer 2

You might need to add debugging code into your procedures to indicate progress within the procedure.

Otherwise, you could explore the routine debugger in IBM Data Studio to help you find errors in SQL Stored Procedures
