SQL NOT Operator


The NOT Operator

The NOT operator is used in combination with other operators to give the opposite result, also called the negative result.

In the select statement below we want to return all customers that are NOT from Spain:

Example

Select only the customers that are NOT from Spain:

SELECT * FROM Customers
WHERE NOT Country = 'Spain';

In the example above, the NOT operator is used in combination with the = operator, but it can be used in combination with other comparison and/or logical operators. See examples below.


Syntax

SELECT column1, column2, ...
FROM table_name
WHERE NOT condition;
