How do I list the parent tables, and relevant columns for a table at the child end of a foreign key constraint .

The following script will list all parent/child relationships, givng the column names at the parent end of the relation in the correct order.

-- Parent / Child / Key Reference --
set pages 50000
set feedback off
spool constraint.log
col parent format a27
col child  format a27
col key    format a21
select a.table_name         Parent,
       b.table_name         Child,
       column_name          Key,
       substr(position,1,1) P
from 
      user_constraints a, user_constraints b, user_cons_columns c
where 
      a.constraint_name = b.r_constraint_name
and   a.constraint_name = c.constraint_name
order by 1, 2, 4;
