How to recover a mistakenly deleted database in SQL Server?

If the database is accidentally deleted, you can try the following methods to recover it:

1. Database recovery using backup: If you have a backup file of the database, you can restore the database by using the backup file. You can easily perform the restoration operation using SQL Server Management Studio (SSMS).
2. Recovery using transaction logs: Within the transaction logs of SQL Server, detailed information about database operations, including delete operations, is recorded. If you have detailed transaction log backups, you can use the Log Sequence Number (LSN) for recovery. Specific recovery steps can be found in the documentation for SQL Server.
3. Recovery using third-party tools: There are some third-party tools available to help recover accidentally deleted databases. For example, tools like ApexSQL Log and Redgate SQL Log Rescue can be used to restore deleted data.

Regardless of the method, it is recommended to backup your data before recovery to prevent further data loss.
