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.
