Exit and rollback everything in script on error

Question

I have a TSQL script that does a lot of database structure adjustments but it\'s not really safe to just let it go through when something fails.

to make things clear:

You could try something like this... If you are using Try block... The error level 16, (or most of application error), immediately transfers the control to the CATCH block without executing any further statements in the try block...

    Begin Transaction

Begin Try

                    --  Do your Stuff

        If (@@RowCount <> 1) -- Error condition
        Begin
            Raiserror('Error Message',16,1)
        End


    Commit
End Try
Begin Catch
    IF @@Trancount > 0
    begin
        Rollback Transaction
    End

    Declare @ErrMsg varchar(4000), @Errseverity int

    SELECT @ErrMsg = ERROR_MESSAGE(),
          @ErrSeverity = ERROR_SEVERITY()

    RAISERROR(@ErrMsg, @ErrSeverity, 1)     
End Catch

Hope this helps...
