Create Restore Command From DB Backup File

This script will read the contents of a DB backup file, and generate a restore command.

Set the value of parameter @backup_path to point to the backup file, run in Query Analyzer, cut/paste the output into another Query Analyzer window, modify as necessary, and run.

This is just a barebones script to demo how this can be done. Modify as necessary to meet your own needs.

Works in SQL 2000 and 7.0. May work in SQL 2005, but it is not tested.
