Course Description
Set operators in SQL Server 2016 are used to compare rows between input sets. This course covers the UNION, INTERSECT, and EXCEPT set operators, as well as the APPLY operator, which is used to evaluate rows in one input set against the expression defining the second input set. This course also introduces the basic components of common table expressions. This course is one of a series of courses that cover the objectives for 70-761: Querying Data with Transact-SQL exam.
