The book is referring to an external site http://www.sql-join.com stating “If you need a primer on joins (or even a refresher), the SQL-Join website provides some detailed examples.”

However, this website seems to no longer exist and gets redirected to a company website https://www.talend.com that does not explain anything about SQL or Joins.

I would suggest linking to the Wikipedia page https://en.wikipedia.org/wiki/Join_(SQL) or other stable resources instead.

As a general note, maybe it would be better to generally link to your own link redirect so that you can change the links later when evil things happen to those given.

Thanks for the heads-up about the broken link. I’ll let the authors know and if there is an actual SQL joins site that still exists will post the link here.
