Matching urls

In this lesson you learned that SQL Server provides the LIKE operator, which determines if a string matches a specified pattern.

You need to verify the URLs of the official sites of every series. You prepare a script that checks every official_site value from the series table to analyze possible wrong URLs.

To make it easier, suppose that the format of the URLs you have to validate must start with 'www.', although we know that there are URLs that have other beginnings.
