Teradata SQL supports the following set operators:

Set Operator Function
INTERSECT Returns result rows that appear in all answer sets generated by the individual SELECT statements.
MINUS /EXCEPT Result is those rows returned by the first SELECT except for those also selected by the second SELECT.

MINUS is the same as EXCEPT.

UNION Combines the results of two or more SELECT statements.

Set operators appear in query expressions. A query expression is a set of queries combined by the set operators INTERSECT, MINUS/EXCEPT, and UNION.
