Correct, parameters are only for field values. The purpose of parameterized
queries, for database engines that support it, is to allow the engine to
prepare and optimize the query for you, allowing you to execute that query
multiple times by just passing different parameters instead of having to
pass the entire SQL and preparing it again. But a query cannot be prepared
and optimized on an unknown table.

Reality is that which, when you stop believing in it, doesn't go away.
