How to use EXCEPT in SQL?

Question

Can anyone explain how to use EXCEPT in SQL?

Answer 1

In SQL, the EXCEPT operator is used to subtracting the result set of the first SELECT statement from the result set of the second SELECT statement. In short, EXCEPT operator return the unique records of first SQL query but not the common records and result set of second select query. EXCEPT is supported in the SQL server but not MySQL.

Here is the syntax to use EXCEPT operator:

SELECT column1, column2,……column

FROM table_name

WHERE condition

EXCEPT

SELECT column1, column2,……column

FROM table_name

WHERE condition;
