This example shows a valid upsert INSERT request.

     UPDATE sales
     SET item_count = item_count + 1
     WHERE (item_nbr = 20
     AND    sale_date = '05/30/2000')
     ELSE INSERT INTO sales (20, '05/30/2000', 1);

After all of the rules have been validated and no row was found that satisfies the compound predicate item = 20 and sale_date = ‘05/30/2000’ for the update, a new row is inserted with item_nbr = 20.

A message indicates the successful insert of one row.
