What is the difference between an action query and a select query? When you are working with action queries, why is it important to create a backup of your database first?
What will be an ideal response?
A select query is used to display and manipulate data but not change it. An action query makes changes to records, or moves records from one table to another. Since there is no undo feature for an action query, the changes they make are permanent. In order to protect your data from mistakes while running action queries, it is a good idea to always create a backup database first, so if the action query does not work as anticipated, you have a backup to revert to.
