TIMESTAMP_TO_SCN(<timestamp>)
 
 
-- The following example inserts a row into the oe.orders table 
-- and then uses TIMESTAMP_TO_SCN to determine the system change 
-- number of the insert operation. (The actual SCN returned will 
-- differ on each system.)
 
INSERT INTO orders (order_id, order_date, customer_id, order_total)
   VALUES (5000, SYSTIMESTAMP, 188, 2345);
1 ROW created.
 
COMMIT;
COMMIT complete.
 
SELECT TIMESTAMP_TO_SCN(order_date) FROM orders
   WHERE order_id = 5000;
 
TIMESTAMP_TO_SCN(ORDER_DATE)
