Snippet Name: INSERT FIRST WHEN
Description: The WHEN clause is evaluated in the order in which it appears in the statement.
For the first WHEN clause that evaluates to true, the database executes the corresponding INTO clause and then skips subsequent WHEN clauses for the given row.
This example uses the FIRST clause to put orders greater than 2,900,000 into the special_orders table and exclude those orders from the large_orders table.
