Advanced SQL (programming) videos | SQL Programming Part 3 - Variables in SQL

Posted by Andrew Gould on 21 November 2012


Using variables allows you to give your SQL procedures a memory. You can store a value in a variable and then retrieve and reuse that value at any point later in the same procedure. This video teaches you how to declare variables, assign values to them and make use of those values in a query. You'll also see how to store the result of a SELECT statement in a variable, as well as how to accumulate the value of a variable. You'll see a couple of methods of displaying the value stored in a variable and we'll end with a quick overview of the global variables in SQL Server.

See our full range of SQL training resources, or test your knowledge of SQL with one of our SQL skills assessment tests.

When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.

Improving the quality of a video

To improve the quality of a video, first click on the Settings icon:

Choose to change the video quality:

Click on Quality as shown to bring up the submenu.

 

The higher the number you choose, the better will be your video quality (but the slower the connection speed):

Connection speed

Don't choose the HD option unless you have a fast enough connection speed to support it!

 

Is your Wise Owl speaking too slowly (or too quickly)?  You can also use the Settings menu above to change your playback speed.
