RE: NESTED MINUS?

Try taking out the "table"'s . This is illegal syntax.

    select * from A where A.f1 in (

        select f1 from A
            minus
        select f1 from B);

The sql above is also very inefficient. You don't need to do the minus. Here is the correct syntax:

    select * from A where A.f1 not in (

        select f1 from B);
