After banging my head against a wall for a while, I finally found this thread from June 2005 in the MySQL support forums regarding using variables in the LIMIT clause. They don’t support it yet. There’s no time table that indicates when it will be supported either. It’s very unfortunate, I was looking forward to benchmarking the difference between our ad hoc code and the stored proc version.

This code will not work: SELECT field from table LIMIT limit_var

Very unfortunate.
