Selecting data in SQL videos | SQL Queries Part 11 - Subqueries

Posted by Andrew Gould on 20 August 2012

The idea of a subquery is pretty simple: it's just one query nested inside another. If that doesn't sound particularly useful then you should watch this video to find out why it is! You'll learn how to place a subquery in a SELECT list or a WHERE clause, how to add criteria to a subquery, and how to handle subqueries which return multiple values.

You can increase the size of the video:

Full screen mode for YouTube

You can view the video in full screen mode as shown on the left, using the icon at the bottom right of the frame.

You can also increase the quality of the video:

Changing resolution

You can improve the resolution of the video using another icon at the bottom right of the frame. This will slow down the connection speed, but increase the display and sound quality. This icon only becomes visible when you start playing the video.

Finally, if nothing happens when you play the video, check that you're not using IE in compatibility view.
