Dan,
See http://dev.mysql.com/doc/mysql/en/declare-handlers.html. Here's a
wee example...
USE test ;
SET @err = 0 ;
SELECT 'Before running errhandlerdemo:', @err ;
CREATE TABLE IF NOT EXISTS testhandler (i INT, PRIMARY KEY(i)) ;
SET GLOBAL log_bin_trust_routine_creators=TRUE
DROP PROCEDURE IF EXISTS errhandlerdemo ;
DELIMITER |
CREATE PROCEDURE errhandlerdemo()
BEGIN
DECLARE EXIT HANDLER FOR SQLSTATE '23000' SET @err=23000;
INSERT INTO testhandler VALUES( NULL) ;
SET @err=-1 ;
END ;
|
DELIMITER ;
CALL errhandlerdemo();
DROP TABLE testhandler;
SELECT 'After running errhandlerdemo:', @err;

Hello,
I've been looking into converting our existing Oracle PL/SQL code to mysql. A
lot of the syntax is pretty straight forward, and really doesn't require much
change from what I've been testing with thus far. However, I'm trying to
handle exceptions, and I cannot seem to find any documentation that shows me
what I'm looking for.
In oracle, we have bits of code like this:
IF INSTR(:new.ACCOUNT_NUM, ' ') > 0 THEN
RAISE AcctNumHasSpace;
END IF;
and then
EXCEPTION
WHEN AcctNumHasSpace THEN
RAISE_APPLICATION_ERROR(-20001, 'Cannot insert space
into ACCOUNT_NUM');
But I cannot seem to figure out how to replicate that behavior. Is it
something that's possible to do as of yet? Or not really? Basically in this
situation, we want the insert to fail if there is a space in that field.
Any advice would be great.
Dan.
