Proper Use of Cascade Delete in Microsoft Access


 S  M  L  XL  FS  |  Slo  Reg  Fast  2x  |  Bookmark Join Now

Today, we're going to talk about Cascade Deletes in Microsoft Access. They're very dangerous, but they can also be very powerful. But of course, remember, with great power comes great responsibility. So we're going to talk about that in today's video.

Ava from Tempe, Arizona (a Platinum Member) asks: In your video about referential integrity, you said that Cascade Deletes are dangerous and that I should avoid them. Can you explain what they are a little more and when I should and should not use them? Are they really that dangerous?

Members

Members will learn how to create a button that will execute some SQL to manually delete an order and its details, without using Cascade Deletes. This method will work across linked tables and allows you to delete exactly what you want. We can also incorporate safeguards, such as verifying that the order isn't paid before we delete it and prompting the user to confirm if they are certain about the deletion.
