Glad you discovered the answer for yourself!
PassThrough queries using native MySQL syntax is hard to beat.
I frequently create a single PassThrough query in Access and then use VBA to
"stuff it" with different MySQL commands. You want to bypass MS Jet and pass
as much work as possible to the server via native mysql flavor of SQL. And
if you are an MS Windows house, Access (PassThrough queries) are a great way
to store procedures for version of MySQL prior to 5.0 which lack that
facility.
