Can I rollback last update on SQL database? [duplicate]
Were you in a transaction? If yes, try entering
ROLLBACK WORK;
If you were not, than restore from backup
no, if the update has been completed successfully, I assume you used SQL Server Management Studio, the changes have been applied.
if it's really important that you revert those updates, you should restore the last backup if you have one and don't bother to loose changes done between backup time and now.
