I use this SQL statement
Select pka.table_name PK_Table_Name, pka.column_name PK_COLUMN_NAME, pkc.table_name FK_TABLE_NAME, pkc.column_name FK_COLUMN_NAME from user_cons_columns pka, user_constraints pkb, user_cons_columns pkc where pkc.constraint_name = pkb.constraint_name and pkb.constraint_type='R' and pka.constraint_name = pkb.r_constraint_name and pka.position = pkc.position and pka.table_name = 'ABC' order by pka.table_name, pka.column_name, pkc.table_name, pkc.column_name

but the performance is too slow. Is any other statement which has much better performance?
