SQL Try It

Test your SQL Skills

On this page you can test your SQL skills.
We will use the Customers table in the Northwind database:
CompanyNameContactNameAddressCity
Alfreds Futterkiste Maria Anders Obere Str. 57 Berlin
Berglunds snabbköp Christina Berglund Berguvsvägen 8 Luleå
Centro comercial Moctezuma Francisco Chang Sierras de Granada 9993 México D.F.

Königlich Essen Philip Cramer Maubelstr. 90 Brandenburg
Laughing Bacchus Wine Cellars Yoshi Tannamuri 1900 Oak St. Vancouver

The Big Cheese Liz Nixon 89 Jefferson Way Suite 2 Portland
Vaffeljernet Palle Ibsen Smagsløget 45 Århus
Wolski Zajazd Zbyszek Piestrzeniewicz ul. Filtrowa 68 Warszawa
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'
