Let's say I had two tables:

CREATE TABLE t1 (

col1 NUMBER PRIMARY KEY);

CREATE TABLE t2 (

        col2 REFERENCES t1(col1),
        col3 VARCHAR2(40));

Then I ran the query:

select a.table_name, b.table_name, b.column_name from user_constraints a, user_cons_columns b where a.r_constraint_name = b.constraint_name and a.constraint_type='R';

I will get back a result set containing

a.table_name = t2
b.table_name = t1
b.column_name = col1

But what query would I run to find "col2"?

Thanks,
