Detailed Description

A branch node for performing a composite function on two child nodes.

This branch is used for general Sql.CompositeFunction.Union, Sql.CompositeFunction.Except, Sql.CompositeFunction.Intersect composites. The left and right branch results must have the same number of columns and column types.
