| I have a large table that I need to play with a devise a solution. I want to make a back up copy of it so that if I crash it I can easily restore. What is the best way to backup/restore a single table? |

| The easiest way is to execute following Select * into TempTable from YourOriginaltable and then if something goes wrong to YourOriginaltable then you can copy back everything from TempTable to YourOriginaltable by following : ALTER TABLE YourOriginaltable NOCHECK CONSTRAINT ALL--Temporarily disable constraint on YourOriginaltable delete from YourOriginaltable --make sure you are not duplicatingInsert into YourOriginaltable Select * from TempTable --YourOriginaltable will be back in the same stateALTER TABLE YourOriginaltable CHECK CONSTRAINT ALL--Place constraint back on YourOriginaltable |
