Hi Lowell,

Sorry for answering until now, but i have been very busy working in another project...

Your guidance was really userful, it worked like a charm!!!

Thank you very much!!! I tested it in a non-working scenario and everything was ok. Now, I will change the table in the production database, but I need to know how to make a proper rollback just in case (I have no problems with my backups), using begin tran / commit tran / rollback tran. Is this recommended? I just want to be sure of the changes and commit those changes, from the management studio, so in case of error recover faster than using the daily backups. (Sorry if this requires to be in a new post. Correct me if it should be.)

Regards,
