Скачать или смотреть Except SQL Server Operator with Example

The SQL EXCEPT Operator in SQL Server can be a handy tool to use.

Let's explore what the SQL except operator is and does

The SQL except operator is placed between two sets of data or tables, ultimately outputting only records from the first data set that does not happen to exist in the second data set. In essence, it spits out all rows in table A "except" for those that are in table B.

One prerequisite of this is that the column structure of the queries using except must be similar.

In this video we’ll dive into an example to clearly illustrate the output of the except operator applied on 2 tables.
