What I want is the syntax to do the following: create procedure myProcedure() begin declare exit handler for ANYTHING_WRONG_THAT_CAN_BE_CAUGHT_WARNINGS_INCLUDED begin rollback; RE_THROW THE_THING_THAT_WAS_CAUGHT; end; start transaction; -- do some stuff commit; end; // The reason being that I want to force a rollback on an error or warning but leave it up to the client to decide what to do with the specific error. The all-cap areas are the portions where I do not mysql stored procedure know what to put. Thanks for any help! Edit ------- I have since learned it is not possible to do what I have asked :'(. Instead I have a single error for anything that goes wrong and used the following code: declare exit handler for sqlwarning, sqlexception begin rollback; call error(); end; (error() does not exist) mysql stored-procedures handler share|improve this question edited Sep 17 '13 at 19:33 djechlin 31.2k1576165 asked Oct 26 '12 at 23:48 nikdeapen 6581820 This question would provide a partial solution: stackoverflow.com/questions/18858567/… –djechlin Sep 17 '13 at 19:44 1 why 'partial'? what's missing? –rsanchez Sep 17 '13 at 22:44 add a comment| 1 Answer 1 active oldest votes up vote 11 down vote +100 To catch all SQL exceptions, use: DECLARE EXIT HANDLER FOR SQLEXCEPTION SQLWARNINGS can be used to catch warnings also. Inside the exception handler, to raise the error or warning that was just caught, use: RESIGNAL See the documentation for the RESIGNAL statement: http://dev.mysql.com/doc/refman/5.5/en/resignal.html This is available since MySQL 5.5 share|improve this answer edited Sep 18 '13 at 11:36 answered Sep 18 '13 at 6:37 Marc Alff 4,3751343 This is exactly what I'm looking for.

InterviewsMySQL InterviewsDBA ScriptSQL Server DBA ScriptPostgreSQL DBA ScriptMySQL DBA Script(: Laugh@dbrnd :)Blog Archives !Contact Me MySQL Error Handling May 21, 2015June 15, 2015 Anvesh PatelMySQL In this post I will describe how to handle errors into mysql stored procedure.Whenever any exception is occurring in a stored procedure, then this is very important to handle this exception by showing proper error messages.If you do not handle the exception, then there would be chance to fail application with certain exception in stored procedure.As per my advise, if you get an error in stored procedure, then instead of exit, you should continue without any error. Means you can show any default or custom error code or message to the application so base on this application can decide to show a proper message at user level.MySQL provides Handler to handle exception in stored procedure.Below is a full demonstration of handler with examples.12345678910/*Create Employee database for demo */CREATE DATABASE Employee;/*Create sample EmployeeDetails table.*/CREATE TABLE Employee.tbl_EmployeeDetails ( EmpID INTEGER ,EmpName VARCHAR(50),EmailAddress VARCHAR(50),CONSTRAINT pk_tbl_EmployeeDetails_EmpID PRIMARY KEY (EmpID))ENGINE = InnoDB;How to declare handler in store procedure:Syntax of Handler: 1DECLARE handler_action HANDLER FOR condition_value ... statementThree type of Handler_Action: CONTINUEEXITUNDOType of Condition Value:mysql_error_codesqlstate_valueSQLWarningSQLExceptionNotFoundHow to write handler in stored procedure ?:E.g.1234DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SELECT 'Error occured';DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET IsError=1;DECLARE EXIT HANDLER FOR SQLEXCEPTION SET IsError=1;DECLARE EXIT HANDLER FOR SQLSTATE '23000' SET IsError = 1;The Above is four different handler example.
