SET column1=value1,column2=value2,...
WHERE condition;

Database

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

Below is a selection from the "Customers" table:

CustomerID FirstName Email Address Username Password
1

2 Lewis M. Ewell LewisMEwell@teleworm.us Himmaing eer5Awair4of

5 April C. Kent AprilCKent@teleworm.us Hisir1937 aiSie3ph

SQL UPDATE Example

Assume we can update the customer "April C." with a new contact person and city.

We use the following SQL statement:

Example

UPDATE Customers
SET FirstName='April C.', Password='Biu95icox8k'
WHERE FirstName='Scott P. Vance';

The selection from the "Customers" table will work fine:

CustomerID FirstName Username Password Country
