# SQL AND & OR Operators

« Previous
Next Chapter »

The AND & OR operators are used to filter records based on more than one condition.

## The SQL AND & OR Operators

The AND operator displays a record if both the first condition AND the second condition are true.

The OR operator displays a record if either the first condition OR the second condition is true.

## Demo Database

In this tutorial we will use the well-known Northwind sample database.

Below is a selection from the "Customers" table:

CustomerID | CustomerName | ContactName | Address | City | PostalCode | Country
--- | --- | --- | --- | --- | --- | ---
1 | Alfreds Futterkiste | Maria Anders | Obere Str. 57 | Berlin | 12209 | Germany
2 | Ana Trujillo Emparedados y helados | Ana Trujillo | Avda. de la Constitución 2222 | México D.F. | 05021 | Mexico
3 | Antonio Moreno Taquería | Antonio Moreno | Mataderos 2312 | México D.F. | 05023 | Mexico
4 | Around the Horn | Thomas Hardy | 120 Hanover Sq. | London | WA1 1DP | UK
5 | Berglunds snabbköp | Christina Berglund | Berguvsvägen 8 | Luleå | S-958 22 | Sweden

## AND Operator Example

The following SQL statement selects all customers from the country "Germany" AND the city "Berlin", in the "Customers" table:

## Example

SELECT * FROM Customers
WHERE Country='Germany'
AND City='Berlin';
Try it yourself »

## OR Operator Example

The following SQL statement selects all customers from the city "Berlin" OR "München", in the "Customers" table:

## Example

SELECT * FROM Customers
WHERE City='Berlin'
OR City='München';
Try it yourself »

## Combining AND & OR

You can also combine AND and OR (use parenthesis to form complex expressions).

The following SQL statement selects all customers from the country "Germany" AND the city must be equal to "Berlin" OR "München", in the "Customers" table:

## Example

SELECT * FROM Customers
WHERE Country='Germany'
AND (City='Berlin' OR City='München');
