SQL SERVER – SQL Basics Video: Joining Tables – SQL in Sixty Seconds #058

This is the 3rd post out of my 10 post series of my videos on my 10th book – SQL Basics. Today will show the importance of data and information.

You can get that in Paperback (USA) and Kindle (Worldwide).

An INNER JOIN clause allows us to join multiple tables in a single query, although it requires a specific condition in order for it to work correctly. We must ensure that the INNER JOIN statement has two tables with at least one common or overlapping field. We already know the Employee and Location tables share a common field (LocationID). The relationship is between Employee.LocationID and Location.LocationID, so we instruct SQL Server that the INNER JOIN is on this field and voila! We have combined two tables into one result set.
