MySQL Stored Procedure Error Handling

I am doing the following workaround: using a SELECT to provocate an error. For example:

SELECT RAISE_ERROR_unable_to_update_basket;

This will result in the following error message (example):

ERROR 1054 (42S22): Unknown column 'RAISE_ERROR_unable_to_update_basket' in 'field list'

I am wrapping my call to a stored procedure in a try { ... } catch { ... } and now can handle this error. This will of course only work for provocating custom error messages from inside your stored procedure and will not handle any SQL or database errors, that might occur (because of duplicate-key entry). In the latter case, you might be able to workaround this using the solution of Johan.
