Quick response measures after accidentally deleting a database

After accidental deletion of the database occurs, the following steps should be performed immediately:

• Stop all database activities: Close all applications and services connected to the database .
• Back up log files: Make sure to copy all transaction log files as they may contain data that can be used for recovery.
• Query log: Check the database log to find information about the delete operation, such as time, user, and statement.

Restore options

SQL Server provides a variety of methods to restore the database:

1. Restore from backup

• If you have a recent database backup, this is the easiest way to restore.
• Use the RESTORE DATABASE statement to specify the backup file and database name.

2. Restore from the transaction log

• If there is no backup, you can try to restore from the transaction log.
• Use the RESTORE LOG statement to specify the log file and restore options (such as WITH RECOVERY).

3. Use DBCC CHECKDB

• In some cases, you can try to use the DBCC CHECKDB command to repair the damaged database and restore data.
• This command performs a series of checks and attempts to repair any damage.

4. Use third-party tools

• If other methods fail, you can use third-party data recovery tools to try to recover lost data.
• These tools can scan the disk for traces of deleted files and attempt to recover them.

Tips
