Your example will not work; you should have written: SELECT foo.id from foo,fee where foo.id=fee.id With inner join, this would be SELECT foo.id FROM foo INNER JOIN fee on foo.id=fee.id Joining a third table would look like SELECT foo.id FROM foo INNER JOIN fee ON foo.id=fee.id INNER JOIN bar ON bar.id=foo.id
