SQL Server INTERSECT and EXCEPT Operator
Multiple SQL Queries may return duplicate values in recordsets from each query result. There could be situations when a single resultset is needed to be returned by combining multiple SQL queries. In SQL Server, there are many SET operators like UNION, EXCEPT, and INTERSECT to merge multiple results of select statements to a single result set. The INTERSECT operator is one of them which is used to filter distinct values.
Structured Query Language (SQL) is a powerful tool for managing and manipulating relational databases. In SQL Server, various operators allow you to perform different types of set operations on your data. Two such operators are EXCEPT
and INTERSECT
, which are used to compare and combine the results of two queries.
