How to you typically handle roll backs for data edits in a multi-user environment? Do you identify the transaction and build a graph of any subsequent dependent transactions and then roll them all back ? Do most RDBMS's provide an interface or mechanism to do this sort of thing? Naive as I am, I thought about restoring from backup, but ...
I've read through MSDN on ROLLBACK TRANSACTION and nesting transactions. While I see the point of ROLLBACK TRANSACTION savepointname, I do not understand ROLLBACK TRANSACTION transactionname. It only works when transactionname is the outermost transaction ROLLBACK always rolls back the entire transaction "stack", except in the case ...

Hi, This might be an easy one for some one but I haven't found a simple solution yet. I'm automating a larger process at the moment, and one step is to back up then drop the database, before recreating it from scratch. I've got a script that will do the back up and drop as follows: Use [Master] BACKUP DATABASE [databaseName] TO DI...

I have a file in my Clearcase repository. I checked it out and modified it, and then checked it back in. I haven't done anything like make a baseline, or rebase, or deliver in my stream/view. I regret having made the changes to this file--I should have undone the checkout, in retrospect. How do I roll back the modifications? (Or und...

Also, a lot of source control resources seem to be for command line users. ...
