Developers think it's obvious, but when you're a consultant it's tough to optimize queries when you don't know the schema by heart!

If that is all you are looking for, then “explain extended” and then show warnings will let you know the ‘database.table’ used by MySQL

It sends the "correct" packet, with a 0 length DB, but you get back an error: "No database selected". I suppose a bug/feature request could be filed to change the behavior of this request. :) I just tested select_db() with an empty DB name, which issues a COM_DB_INIT at the protocol layer, and it doesn’t work.
