public class SetOperator
extends Operation

SQLFragment for dealing with queries that are linked using one of the SET operators INTERSECT, UNION, MINUS and UNION ALL. The fragment consists of two other fragments, one which is a SQLQuery and the other that is either another SQLQuery or another SetOperator.

Not to be confused with SetOperation which deals with operators of value sets (e.g. IN, BETWEEN etc).

Since:

11.1.2
