Database connection problems, database copy difficulties, abrupt termination, transitory faults, dangerous malware, and other issues plague SQL Server in any business. Users frequently lose their SQL data in such situations, and they must go through a lengthy recovery process to restore SQL Server Database.

The blog discusses how to recover SQL Server databases without and with backups using both manual and automated approaches. You may manually restore the database with some data loss by using the ‘DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS’ command. T-SQL Commands or SQL Server Management Studio can be used to restore the SQL database from the backup file. We’ll give you a quick overview of both of these approaches here.

It might be difficult to restore a SQL Server database and its lost or inaccessible data if you do not have an updated backup or backup is faulty.

Methods to Recover SQL Server Database without Backup

Only if the database you wish to restore is still connected to the SQL Server instance will this technique function. You can’t use the DBCC CHECKDB command if your database is offline. The only alternative in that scenario is to employ a specialist SQL Recovery Software. If you do not have a backup of your SQL database, consider using the ‘DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS’ command to fix it.

Note: Running DBCC CHECKDB does not ensure that the databases will be brought up to date. Additionally, utilizing the ‘REPAIR_ALLOW_DATA_LOSS’ option may cause data loss.

Steps to Recover SQL Server Database using DBCC CHECKDB

Connect to an instance of SQL Server by using SQL Server Management Studio (SSMS).
Set the database to a state of EMERGENCY.
To check for corruption issue, run DBCC CHECKDB on the database.

Step 1: Enable emergency mode in the database.

Change the databases status to EMERGENCY, which gives the administrator read-only access.
Run the following query in SSMS to put the database in EMERGENCY mode:

Step 2: Look for corruption issues.

Once the administrator has access to the database, use the DBCC CHECKDB command to look for corruption issues:
DBCC CHECKDB (Dbtesting)
If DBCC CHECKDB discovers any database problems, it will provide appropriate repair solutions to resolve the problem.

Step 3: Set the database on the SQL server to single-user mode.

Put the damaged database in single-user mode before using the DBCC CHECKDB repair options to prevent other users from altering the data during the repair process. Follow these steps to change SQL database mode to SINGLE USER:

Method 1: Making Use of a Graphical User Interface (GUI)

Right-click the database you wish to restore, then select Properties from the drop-down menu.
Click Options in the Database Properties window.
Select SINGLE USER from the Restrict Access drop-down box under the State tab, then click OK.

Method 2: Use T-SQL (Transact-SQL) Commands

By performing the following T-SQL query in SSMS, you may also change the database to SINGLE USER mode:
Dbtesting SET SINGLE USER ALTER DATABASE

Step 4. Repairing the Database.

To restore the SQL server database, execute DBCC CHECKDB with the REPAIR ALLOW DATA LOSS repair option after changing the database mode to SINGLE USER:

Step 5: Set Database back to MULTI_USER Mode

After successfully repairing the database, set the database to MULTI_USER mode by executing the following command:

ALTER DATABASE Dbtesting SET MULTI_USER

If DBCC CHECKDB fails, what more can you do?

When using the ‘DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS’command, certain database pages may be deleted, resulting in data loss. When working with highly damaged SQL database files, DBCC CHECKDB procedures may fail and generate an . Use Aryson SQL Database Recovery software to recover all components of a severely damaged MS SQL database while retaining database integrity. The SQL Recovery Software assists in restoring database access with little human work and time.

Recover SQL Server Database with Software

SQL Database Recovery Software does not risk data loss, unlike the ‘DBCC CHECKDB’ repair command. The database can be restored to its original, undamaged state when the file has been fixed. Database consistency problems, database in suspicious mode, recovery pending mode, and other database corruption faults may all be handled using the SQL database recovery tool.

Follow Steps to Recover SQL Server Database using Software

On your computer, run the MS SQL Database Recovery software. Select the Open button.
Select the corrupt MDF file using the Browse option.
From the list, select any corrupt MDF file and click Open.
Next, choose a recovery mode and press the OK button.
The scanning procedure for the chosen file is complete.
Select the OK button.
In the left-hand pane, expand the folders. In the “Preview Pane” double-click any item to see a preview of it.
Save the items in the left-hand window by selecting them.
Save your work by using the Save button.
Choose the location where you want the restored data to be saved. Select the OK button.
The procedure of saving has been completed. Select the OK button.
To exit the software, click Close. Select the Yes option.

Conclusion

If a SQL Server crashes, disc failure, database corruption, or unintentional data loss, you may rely on the backup to restore the database and its contents. However, there may be times when the backup is unavailable or corrupted. Implementing the strategies mentioned in this piece, on the other hand, can equip you to respond swiftly and efficiently to any crisis. You can attempt manually restoring the database or utilize SQL Server Database Recovery tools.
