SQL AND, OR, NOT

SQL AND, OR and NOT Operators

The WHERE clause can be combined with AND, OR, and NOT operators.

The AND and OR operators are used to filter records based on more than one condition:

• The AND operator displays a record if all the conditions separated by AND are TRUE.
• The OR operator displays a record if any of the conditions separated by OR is TRUE.

The NOT operator displays a record if the condition(s) is NOT TRUE.

AND Example

The following SQL statement selects all fields from "Customers" where "Country" is "Germany" AND "City" is "Berlin":

SELECT * FROM Customers
WHERE Country = 'Germany' AND City = 'Berlin';

OR Example

The following SQL statement selects all fields from "Customers" where "City" is "Berlin" OR "München":

SELECT * FROM Customers
WHERE City = 'Berlin' OR City = 'München';

NOT Example

The following SQL statement selects all fields from "Customers" where "Country" is NOT "Germany":

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