-- DB2 has a MERGE statement which is designed to merge the rows from one table into another.
-- This technique adapts that to the case of a single row of literal values (such as might be provided in an application program).
-- This is informally known as an 'upsert' - a portmanteau of "update" and "insert".

-- The key parts of this statement are:
-- 1. The USING clause provides the values for the entire row, and also provides column names for these.
-- 2. The ON clause is the means for detecting an existing record (like a join's ON clause).
-- 3. The WHEN MATCHED clause specifies which columns to update in an existing record. Obviously this won't contain the keys, but needn't contain all the other columns either.
-- 4. The INSERT VALUES clause uses the column names provided in the USING clause.
