SQL NOT Operator
The NOT Operator
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:
Select only the customers that are NOT from Spain:
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.
SELECT column1, column2, ...
WHERE NOT condition;
Below is a selection from the Customers table used in the examples:
||Alfreds Futterkiste||Maria Anders||Obere Str. 57||Berlin||12209||Germany|

WHERE CustomerName NOT LIKE 'A%';
Select customers with a customerID not between 10 and 60:
WHERE CustomerID NOT BETWEEN 10 AND 60;
Select customers that are not from Paris or London:
WHERE City NOT IN ('Paris', 'London');
NOT Greater Than
Select customers with a CustomerId not greater than 50:
WHERE NOT CustomerID > 50;
Note: There is a not-greater-then operator:
!> that would give you the same result.

Select customers with a CustomerID not less than 50:
WHERE NOT CustomerId < 50;
