When temporal tables are referenced in queries involving set operations (UNION, INTERSECT, MINUS, and EXCEPT) all queries inherit the temporal qualifier from the topmost query.

If temporal qualifications are required at the level of individual queries, add them to the FROM clause or place the query with the required qualification in a derived table.
