Using multiple select items in a nested exists query

The use of multiple columns in this example is the same as selecting a single c1 or c2 column in the nested exists query.

1> create table t1(c1 int, c2 int)
2> go
1> create table t2(c1 int, c2 int)
2> go
1> select * from t1 where exists (select c1, c2 
   from t2)
2> go

You cannot mix an asterisk with other select items, such as:

1> select * from t1 
    where exists (select t2.*, c1 from t2)
2> go
