I have a procedure try_a which calls another procedure try_b in both the procedures i have declared exit handler for sql exception. Suppose in try_b divide by zero error is encountered then that is returned using SIGNAL. When try_a (exit http://stackoverflow.com/questions/24313909/pass-error-from-inner-stored-procedure-db2 handler written)calls try_b then on case of divide by zero error in try_b ,sql exception of inner block is not shown. Can you please help how can this be achieved. I don't have a sample code now. Will try to put that tomorrow. stored-procedures exception-handling db2 procedure procedural-programming share|improve this question asked Jun 19 '14 at 18:32 user2342436 362112 ... Is it at all possible to rewrite try_b to not generate a divide-by-zero error? That particular one usually indicates that you haven't sufficiently guarded against it in the first place. What should the "result" be in such a case? –Clockwork-Muse Jun 20 '14 at 2:54 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote When you use SIGNAL in the inner stored procedure, the condition that is raised is the user-defined type, not the original condition that cause the inner condition handler to be invoked. It has its own SQLCODE, SQLSTATE, and message. You could use the RESIGNAL statement to raise the same condition. Alternatively, you could log error messages to a temporary table or a file in each condition handler. share|improve this answer answere

I dont think you need to declare it. Try: RAISE_ERROR ('77000', 'TOTAL_ERROR_CNT MAX_THRESHOLD') Jul 5 '07 #2 P: n/a Serge Rielau Lennart wrote: RAISE_ERROR ('77000', 'TOTAL_ERROR_CNT MAX_THRESHOLD') RAISE_ERROR() is the choice to raise an exception _within_ an SQL statement. Commonly it's used as part of COALESCE or CASE-expression. Within SQL PL the SIGNAL statement performs the same function.
