Hello!
Its a beginner question, and sorry for nerving.
Lets say I have an already existing database with 6 fields: Mitarbeiter, Nachname, Vorname, Geschlecht, Geburtsdatum, AbteilungID.
Now I would add a field called "New Field" and fill the cells with the first 4 letters of the Field "Nachname". (Like in the attached picture)
How could I do that?
Kind regards
