You have to type your 50 table names only once, when you create your MERGE table (It is a *table* not a function). If you want to add new tables, you run ALTER TABLE. Looking at the manual should help ;) : http://www.mysql.com/doc/en/MERGE.html Just wondering: Why don't you use a single table, since they all have the same structure ?
