Getting the database out of LOADING state
When restoring multiple backups, each backup needs to use the NORECOVERY option to keep the database in a loading state so additional backups can be restored. However, because the database is still in LOADING, you may encounter an unusable transaction log backup, leaving you unable to restore the file. To reset the status of the database, open Query Analyzer and use T-SQL to issue a BACKUP command:
RESTORE DATABASE Northwind WITH RECOVERY
This command resets the status of the “Northwind” database and allows users to access it. No additional restores can be issued after this command is executed.
