Query a Table's Foreign Key relationships

Question

For a given table \'foo\', I need a query to generate a set of tables that have foreign keys that point to foo. I\'m using Oracle 10G.

Answer 1

Here's how to take Mike's query one step further to get the column names from the constraint names:

select * from user_cons_columns
where constraint_name in (
  select constraint_name 
  from all_constraints
  where constraint_type='R'
  and r_constraint_name in 
    (select constraint_name
    from all_constraints
    where constraint_type in ('P','U')
    and table_name=''));
