Hello,

I accidentally deleted a column in my Access database, and do not know how to "undo".
The undo button isn't an option, so do I need to do some system re-store or something?

Access is a very unforgiving app in that when working with tables, you only get 1 undo (with the exception of deleting because once its gone, it's gone).

You could try to do a restore, but usually with windows restore, the files remain the same and the system configuration is reset back to the previous time.

My recommendation, before ever making changes to a database, duplicate it and work on that just in case something happens. It has saved me numerous times.
