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

I know it's kinda late to answer but let me answer anyway, some of the answers above are quite complicated hence here is a much simpler take.

       `SELECT a.table_name child_table, a.column_name child_column, a.constraint_name, 
       b.table_name parent_table, b.column_name parent_column
       FROM all_cons_columns a
       JOIN all_constraints c ON a.owner = c.owner AND a.constraint_name = c.constraint_name
       join all_cons_columns b on c.owner = b.owner and c.r_constraint_name = b.constraint_name
       WHERE c.constraint_type = 'R'
       AND a.table_name = 'your table name'`
