This section provides examples that show how the atomic upsert form of UPDATE works, including error cases. All examples use the same table called sales, which is defined as:

     CREATE TABLE sales, FALLBACK
       item_nbr   INTEGER NOT NULL,
       sale_date  DATE FORMAT 'MM/DD/YYYY' NOT NULL,
       item_count INTEGER)
     PRIMARY INDEX (item_nbr);

Assume that the table has been populated with the following data.

     INSERT INTO sales (10, '05/30/2000', 1);
