select p.* from table A p, B q where p.id=q.id

or

select p.* from table B q , A p where q.id=p.id

Why do people constantly change table names for queries, although, as here, it gain them
nothing? It often makes for less clarity (for which table is this an alias???). This I
would write

select A.* from A JOIN B USING (id)
