Schritte zur Umstellung der SQL-Datenbank

• Erzeuge neues Feld key und web_object_created

       alter table personal_www add column key text;
       alter table personal_www add column web_object_created text;
       alter table personal_www add column "group" text;
  alter table personal_www add column "_month_arrival" text;
  alter table personal_www add column "_month_departure" text;
  
  

• Belege das Key Feld

   update personal_www set key = trim(both ' ' from vorname)||'_'||trim(both ' ' from name)
  

• Umbenennen

   alter table personal_www rename vorname to first_name;
   alter table personal_www rename name to last_name;
   alter table personal_www rename position to status;
   alter table personal_www rename abteilung to department;
   alter table personal_www rename heimat_inst to home_inst;
   alter table personal_www rename stay_at_mpiwg to date_stay_at_mpiwg;
  

• Schalte "nicht null" Eigenschaft von id ab, id darf dazu nicht mehr primär key sein.

• lasse cleanDBUp.py über die Datenbank laufen, um doppelte zu löschen.
