SELECT and INSERT-SELECT Statements with Set Operators

Only the SELECT and INSERT-SELECT SQL statements can use the set operators UNION, INTERSECT, and MINUS/EXCEPT. The set operators enable you to manipulate the answers to two or more queries by combining the results of each query into a single result set.

The set operators can also be used within these operations:

View definitions

Derived tables

Subqueries

INSERT … SELECT statements

You cannot use the set operators with LOB columns.
