Thread: nested query

I have two linked tables Table1 and Table2. I have deleted some rows in table1
Now I need two delete the rows in table2 that correspond to the rows
deleted in table1. The two table are linked by field id.
I tried the following but with no success:
delete * from table2 where not exists (select * from table1 where
table2.id=id);

Any help much appreciated.

How about:

DELETE FROM table2 WHERE id NOT IN (select id FROM table1);
