SQL Not
The NOT Operator
When used with other operators, the NOT operator yields the opposite result, sometimes known as the negative result.
We wish to return all consumers who are not from Spain as stated in the select statement below:
Example
Select only the customers that are NOT from Spain:
SELECT * FROM Customers
WHERE NOT Country = 'Spain';
The NOT operator can be used in conjunction with other comparison and/or logical operators, as shown in the example above when it is used with the = operator. View the examples that follow.
Syntax
SELECT column1, column2, …
FROM table_name
WHERE NOT condition;
