Try it: Delete a Record in a Table
Select the new movie, Romeo and Juliet, and delete
it. Click OK at the confirmation message if you see one. Can you
undo that deleted record?
Try it: Add another record:
Enter the Title: Romeo and Juliet
When you recreated the Romeo and Juliet record, what ID number was
automatically assigned?
As a database administrator, the Computer Mama gets
very nervous when records are deleted. Each record is related to all
of the others.
For example, how many customers rented the
Romeo and Juliet movie when
it had ID #363?
Whenever a record is deleted you may end up with holes in
your data.
The tables, and the reports that use them, may be incomplete.
