Techniques to Repair MS SQL Database
Dealing with a corrupted SQL Server database can be stressful, especially when you’re unsure what caused it or how much damage has been done. But don’t worry. There are a few techniques you can try to repair the database and recover your important data. Let‘s explore the techniques:
Manual Method to Repair MS SQL Server Database
You can repair the MS SQL Server database manually using methods like DBCC CHECKDB, restoring from backup, using Emergency Mode, or exporting data. These steps need caution and may involve some data loss.
Method 1: Use DBCC CHECKDB with Repair Options
This method helps you detect and fix logical errors within the database using built-in SQL repair commands.
| ALTER DATABASE [YourDBName] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;DBCC CHECKDB ([YourDBName]) WITH REPAIR_REBUILD;DBCC CHECKDB ([YourDBName]) WITH REPAIR_ALLOW_DATA_LOSS;ALTER DATABASE [YourDBName] SET MULTI_USER; |
Note: REPAIR_ALLOW_DATA_LOSS may remove some data during the fix.
Method 2: Restore SQL Database from a Backup
This approach lets you recover the database from the last clean backup, if available.
- Firstly, start SQL Server Management Studio (SSMS).
- After that, right-click the corrupted Database > Tasks > Restore > Database.
- Further, select the last known good backup file (.bak).
- Lastly, select OK to complete the restoration.
Method 3: Set Database to Emergency Mode (For Suspect Mode)
In this process, emergency Mode gives read-only access to the database and allows repair even when the database is in a suspect state. Run the following queries to get it done:
| ALTER DATABASE [YourDBName] SET EMERGENCY;ALTER DATABASE [YourDBName] SET SINGLE_USER;DBCC CHECKDB ([YourDBName]) WITH REPAIR_ALLOW_DATA_LOSS;ALTER DATABASE [YourDBName] SET MULTI_USER; |
Repair MS SQL Database Using a Professional Method
