This means that when a generic SQLException is raised within a stored procedure it is hard/impossible to derive the exact nature of the error. Does anybody have a workaround for deriving the SQLSTATE of an error in a MySQL stored procedure that does not involve declaring a handler for every possible SQLSTATE? For mysql error handle example - imagine that I am trying to return an error_status that goes beyond the generic "SQLException happened somewhere in this BEGIN....END block" in the following: DELIMITER $$ CREATE PROCEDURE `myProcedure`(OUT o_error_status varchar(50)) MY_BLOCK: BEGIN DECLARE EXIT handler for 1062 set o_error_status := "Duplicate entry in table"; DECLARE EXIT handler for 1048 set o_error_status := "Trying to populate a non-null column with null value"; -- declare handlers ad nauseum here.... DECLARE EXIT handler for sqlexception set o_error_status:= "Generic SQLException. You'll just have to figure out the SQLSTATE yourself...." ; -- Procedure logic that might error to follow here... END MY_BLOCK$$ Any tips?
