The techniques range from "checking the error code" after a transaction or statement, to developing error or condition handlers. In SQL PL, the error processing is usually done through the use of condition handlers. This simplifies development since rarely used error handling code can be placed into separate blocks of code. However, this technique of encapsulating error code in a condition handler isn't always used by developers, especially those coming from environments where this technique is not available. The generic error handler approach, where all error information is saved in local variables, is usually a result of porting a stored procedure from some other database platform. An example of this technique is shown below: DECLARE SQLCODE INT; DECLARE SQLSTATE CHAR(5); DECLARE RC_SQLCODE INT DEFAULT 0; DECLARE RC_SQLSATTE CHAR(5) DEFAULT '00000'; DECLARE CONTINUE HANDLER FOR SQLEXCEPTION, SQLWARNING, NOT FOUND VALUES (SQL

I know how to stored procedure catch a specific one with a Declare Handler, however I would like all of them. For example, here I catch the 72822 signal. DECLARE EXIT HANDLER FOR SQLSTATE '72822' BEGIN IF ( var = 'OK' ) RESIGNAL SQLSTATE '72623' SET MESSAGE_TEXT = 'Got SQLSTATE 72822'; ELSE RESIGNAL SQLSTATE '72319' SET MESSAGE_TEXT = var; END; I will call a stored procedure that I do not know the code, and I have to be able to deal with all possible signals (for example insert procedure error handling the signal code in a table.) I would like something like DECLARE EXIT HANDLER FOR ALL stored-procedures db2 sql-pl share|improve this question asked Feb 10 '14 at 14:10 AngocA 5,75621744 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote That would be DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING, I think. http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.sql.ref.doc/doc/r0004239.html share|improve this answer answered Feb 10 '14 at 15:34 mustaccio 10.7k41933 1 The answer above is a way to do this. I would recommend, however, that you separate the handlers (depending on the application). You would want an exit handler for the exceptions, but you will probably want a continue handler for the warnings. DECLARE CONTINUE HANDLER FOR SQLWARNING This is helpful because you do not always want to exit when there is simply a conversion. –jgriffin Feb 10 '14 at 15:58 @mustaccio It is just a question, are you interested to develop an open source framework for unit test in SQL PL? contact me if you are interested: angoca at yahoo dot com –AngocA Feb 10 '14 at 16:15 Agree with @jgriffin. Continue handlers can be useful for exceptions as well, because you may want to recover from certain types of errors (e.g. create a table if it didn't exist). –dan1111 Jun 30 '14 at 7:43 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up u

I have a procedure try_sk as given below: CREATE or replace PROCEDURE tempdb.try_sk(in var1 integer,out o_var1 integer,out o_error varchar(60) ) specific tempdb.try_sk BEGIN --declare ct_date date; declare i_var1 integer; declare v_sqlstate char(5) default '00000'; declare v_sqlcode integer; declare sqlstate char(5) default '00000'; declare sqlcode integer; declare v_tracker varchar(50); declare V_EXIT_MESSAGE varchar(70); declare o_error varchar(70); DECLARE continue HANDLER FOR SQLEXCEPTION,SQLWARNING,NOT FOUND BEGIN VALUES (SQLCODE,SQLSTATE) INTO V_SQLCODE,V_SQLSTATE;-- SET V_EXIT_MESSAGE = 'ERRORQLSTATE-'|| TRIM(V_SQLSTATE) || ',' || TRIM(CHAR(V_SQLCODE)) || ' AT ' || v_tracker;-- SIGNAL SQLSTATE VALUE V_SQLSTATE SET MESSAGE_TEXT = V_EXIT_MESSAGE;-- END; /*DECLARE GLOBAL TEMPORARY TABLE SESSION.t_error ( error varchar (70) ) ON COMMIT PRESERVE ROWS WITH REPLACE NOT LOGGED IN PDPG_USERTEMP; insert into session.t_error(error) values(v_exit_message); commit;*/ SET V_TRACKER = 'divide by var1'; set o_error = v_exit_message; begin declare c1 cursor with return to caller for select o_error from sysibm.sysdummy1; open c1; end; select 1/var1 into i_var1 from sysibm.sysdummy1; set o_var1 = i_var1; END here i am just dividing 1 by the input parameter we pass while calling proc. In case 0 is passed as input parameter(call try_sk(0,?,?), i get the below error message as desired.
