Exit Handler for SQLEexception
Posted by: John Noble

Hi folks,

Here is exit handler for my sproc

DECLARE EXIT HANDLER FOR sqlexception
BEGIN
DELETE FROM shopMaster WHERE receiptNo = p_receiptNo;
DELETE FROM shopDetail WHERE receiptNo = p_receiptNo;
ROLLBACK;
SELECT -1;
END;

The problem is even the though the sproc works fine, it always returns -1 as a value. Note, it does not delete from shopMaster and shopDetail. To me it should be returning 1.

Makes no sense to me...

Any ideas ??

Thanks,

J



The full sproc is below...
