| If you have transaction log backups you can restore to a point-in-time just-before the accident.You could also restore to a new, temporary, database and then "sort out" the data by copying data from the Temp database selectively.Kristen |

What type of command here?Suppose you want to update column value by adding 10. But you mistakenly multiplied it. In this case you can undo it by dividing by 10MadhivananFailing to plan is Planning to fail |

| You do not need to take a backup just before an "accident".Do you have recent FULL back and is your database running in FULL Recovery model?If NO then there is no easily feasible way to reverse it (unless you can reverse the calculation as Madhi explained)If YES take a TAIL TLog backup and restore to "point-in-time" just before the accident.You can restore to new, temporary, database and then "copy" data from that to your Live database to sort the problem out (without losing other data you have changed since) |
