Works great. As usual don't forget to backup your database before running this script.

Für kleine Datenbanken ist das Script super.
Hat man eine Menge Daten, dann wird der Server in die Knie gezwungen. Dann kann man doch meist nur Spalte für Spalte einzeln ändern.

Hi,

thanks for that script. I test it and it works great.
But I need a correction only for one table and two columns.

But I'm not a developer. Ist ist possible to customise your script for that purpose?

Thx
