I apply this technique to run very sophisticated database update processes on the systems I manage. In my case, we run a combination of SQLCMD and BCP to execute large database updates and reports from those updates.

It is very easy to make changes to the processes and it provides the flexibility of executing on demand when the process simply cannot be scheduled reliably.

BTW...I agree with the comments by the user about using OSQL...be sure to check books online for the new SQLCMD command line syntax and write your batch files to that spec instead of the OSQL spec.
