On this page you can test your SQL skills.

We will use the Customers table in the Northwind database:

To preserve space, the table above is a subset of the Customers table used in the example below.


Try it Yourself

To see how SQL works, you can copy the SQL statements below and paste them into the textarea, or you can make your own SQL statements.

SELECT * FROM customers

SELECT CompanyName, ContactName FROM customers

SELECT * FROM customers WHERE companyname LIKE 'a%'

SELECT CompanyName, ContactName
FROM customers
WHERE CompanyName > 'a'

When using SQL on text data, "alfred" is greater than "a" (like in a dictionary).

SELECT CompanyName, ContactName
FROM customers
WHERE CompanyName > 'g'
AND ContactName > 'g'
