A host parameter (a.k.a. "?") can only be used in places where it is legal to put a literal value. You cannot use it as a place holder for program structure. Changing a table in a query can result it radically different compiled code. (Use EXPLAIN to see this.) It is not feasible to recompile the SQL statement in response to a bind(). -- D.
