i would like to restore this BackupDB1.bak into existing DBase2 db.

Tq..hi

you have to use the REPLACE option with the RESTORE command.

Look for help in the Book on line: RESTORE, RESTORE (described)|||What is the exact error you are getting|||True you should specify the error message to assess the issue.

Also are you trying to restore SQL database to a dbase2 database?
