Modify backend table with new field

Environment Desktop Access 2013 database with front end and backend (standard).
When starting, a bat file copies a master FE to a temp area and then executes the FE from the temp area.
I have a number of different sites, each with their own separate network, the same copy of the FE and their own BE.
The BEs are structurally the same.
Problem: I need to add a field to the standard BE.
Normally, I put a new version of the FE to the various sites,  the FE software checks the version of the BE and if neccessary manipulates it so the BE is compatible with the new FE version.  For example, I can add a new table to the BE from a deployed FE.
The question is  - how do I code it so that it adds a field to a backend table.  I know how to do that for adding a field to a database but not when the table is linked.  Any ideas.

HOw do I modify the table while executing in the Front End.  Basically, how do I execute in one database and modify the structure of a  table (add a field) in another database.
Do you have any sort of code sample which does this?

You can use this code (correct names):
Dim dbs As DAO.Database
Set dbs = DBEngine.Workspaces(0).OpenDatabase("C:\Somepath\DBName.accdb")
dbs.Execute ("ALTER TABLE YourTableName ADD COLUMN FieldName Text(25)")

Open in new window
