How to catch and re-throw all errors in MySQL

Question

I can\'t seem to find anywhere how to catch and re-throw any errors or warnings that can occur in a procedure.

What I want is the syntax to do the following:

<         


        

Answer 1

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
