Hmm. Simply replacing the field list with count(*) should work, too. If you
only need the count after having executed the select, I'm pretty sure there's
something in the API that gives you that without a second query, although I'll

There is a single situation when concurrent reads and writes are possible on
MyISAM, however: when your table has no holes in the
