How to add an additional field in the existing database table
Neither adding a field to the existing table nor adding a table should
affect existing data. If you are adding a required field (that is, data entry required) I expect you will need to populate that field in all records, perhaps by way of an update query, but the details depend on what exactly you are trying to do.

Open existing table in design view, add the new field and press save. In the Tables pane of the db window press "Create new Table" or find that option in the menu/ribbon. Neither of these actions has the slightest effect on existing data. -- Rick Brandt, Microsoft Access MVP Email (as appropriate) to... RBrandt at Hunter dot com |

In a split app you would give them a new front end that would run code upon first use to modify the existing table and to create the new table. If your app is not split then you did it wrong. Now would be the time to fix it. -- Rick Brandt, Microsoft Access MVP Email (as appropriate) to... RBrandt at Hunter dot com |

But it does show that you didn't design the app very well. This is the kind of thing that should have VERY RARELY in any production app. The fact that you need to do it should indicate either that you didn't design it well, or the client was derelict in describing the requirements. -- David W.
