SQL AND Operator
The SQL AND Operator
WHERE clause can contain one or many
AND operator is used to filter records based on more than one
condition, like if you want to return all customers from Spain that starts with
the letter 'G':
ExampleSelect all customers from Spain that starts with the letter 'G':
WHERE Country = 'Spain' AND CustomerName LIKE 'G%';
SELECT column1, column2, ...
WHERE condition1 AND condition2 AND condition3 ...;
AND vs OR
AND operator displays a record if all the conditions are TRUE.
OR operator displays a record if any of the conditions are TRUE.
Below is a selection from the Customers table used in the examples:
||Alfreds Futterkiste||Maria Anders||Obere Str. 57||Berlin||12209||Germany|

|3||Antonio Moreno Taquería||Antonio Moreno||Mataderos 2312||México D.F.||05023||Mexico|
||Around the Horn||Thomas Hardy||120 Hanover Sq.||London||WA1 1DP||UK|
|5||Berglunds snabbköp||Christina Berglund||Berguvsvägen 8||Luleå||S-958 22||Sweden|
All Conditions Must Be True
The following SQL statement selects all fields from
Country is "Germany" AND
City is "Berlin" AND
PostalCode is higher than 12000:
WHERE Country = 'Germany'
AND City = 'Berlin'
AND PostalCode > 12000;
Combining AND and OR
You can combine the
The following SQL statement selects all customers from Spain that starts with a "G" or an "R".
Make sure you use parenthesis to get the correct result.
Select all Spanish customers that starts with either "G" or "R":
WHERE Country = 'Spain' AND (CustomerName LIKE 'G%' OR CustomerName LIKE 'R%');
Without parenthesis, the select statement will return all customers from Spain that starts with a "G", plus all customers that starts with an "R", regardless of the country value:
Select all customers that either:
are from Spain and starts with either "G", or
starts with the letter "R":
WHERE Country = 'Spain' AND CustomerName LIKE 'G%' OR CustomerName LIKE 'R%';
