Creating or Updating with the Expression builder

What you do once you open the Expression Builder will depend on what you need to do. You can add a built-in function so that data like the year will automatically generate. You can add a field or an operator. You can even set up a fixed value to do things like limit the number of characters that can be entered into a field.

You will need to test your work once you are done. Any change you make to a database can cause issues if the change isn’t done correctly. The biggest problem is when it corrupts the MDB file or erases existing data. If you find you need assistance, contact an expert to help with MDB file corruption repair or Access recovery.
