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 mysql stored procedure SQLSTATE of an error in a MySQL stored procedure that does not involve declaring a handler for every possible SQLSTATE? For 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?

MySQL introduced the SIGNAL and RESIGNAL statements in version 5.5 (as per the SQL 2003 spec) to serve that purpose. It allows you to raise your own error conditions from your stored procedures, triggers, and events. In today’s article we’ll learn some of the key differences between SIGNAL and RESIGNAL as well as how to utilize both. Basic Syntax Before MySQL 5.5, developers had to resort to workarounds such as deliberately referring to a nonexistent table to cause a routine to throw an error. Thankfully, SIGNAL (and RESIGNAL) may now be employed to provide error information to a handler and/or to the calling process. Moreover, SIGNAL provides some control over the error's attributes such as the error number, SQLSTATE value, and message. Here is the basic syntax for the SIGNAL statement and an explanation of each part: SIGNAL SQLSTATE | condition_value [SET signal_information_item= value_1, [, signal_information_item] = value_2, etc;] Following the SIGNAL keyword is an SQLSTATE value or a condition name declared by a DECLARE CONDITION statement. Notice that the SIGNAL statement must always specify an SQLSTATE value or a named condition that defined with an SQLSTATE value. Related Articles MySQL Numeric Overflow Gotcha An Overview of the MySQL Performance Schema MySQL Date Gotchas Importing Into MySQL from Other Databases The SQLSTATE value for a SIGNAL statement consists of a five character alphanumeric code. The full list of pre-defined codes are listed in the docs. Never start your own SQLSTATE code with '00' because such values indicate success and are not valid for signaling an error. If your value is invalid, a Bad SQLSTATE error occurs. For catch-all error handling, you should assign an SQLSTATE value of '45000'
