You can use standard SQL features within the same query to make your statements more sophisticated.

For example, you can use ordered analytical functions in the following ways.

Use an analytical function in this operation … To …
INSERT … SELECT populate a new column.
derived table create a new table to participate in a complex query.

Ordered analytical functions having different sort expressions are evaluated one after another, reusing the same spool file. Different functions having the same sort expression are evaluated simultaneously.
