A Common Table Expression makes perfect sense, to split a complex query
into
smaller parts.
... but a Common Table Expression can only be used within the same SELECT
statement (incl. other CTEs and nested Sub-Selects).

... If the same CTE has to be used multiple times in different SELECT
Statements it makes more sense to create and use a (permanent) view.
