Advanced SQL (programming) videos | SQL Programming Part 12 - Cursors

Posted by Andrew Gould on 26 March 2013


Most of the operations you perform in SQL work against an entire set of records in one go. Cursors, on the other hand, allow you to process a set of records one row at a time. In this video you'll learn how to declare a cursor and how to make it step through a set of records. Along the way you'll learn about the various FETCH statements and additional cursor options. From a practical point of view you'll see how to execute a stored procedure against each record in a table and how to use a cursor to update data in a table by creating a running total column.

Making a  video bigger

You can increase the size of your video to make it fill the screen like this:

Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.

 

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):

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.
