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 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' |
