Ways to Fix the MS SQL Error 3457
There are several ways to fix this error. Here are some possible ways.
Restore Database from Backup
The backup is used to restore the database from a previous status where the database was working. It is common to back up the database daily. If the database fails for any reason, it is possible to restore information from the backup of a selected date.
To restore the database from backup, you can use the SQL Server Management Studio (SSMS). In the SSMS, go to the Object Explorer, right-click on the database, and select the Restore Database option.
Select the Device option and press the Browse button to select the backup.
Select the backup sets to restore the database and press OK.
Repair the Database using DBCC CHECKDB Command
The Database Console Commands (DBCC) are used in SQL Server to check the status of the database or some database objects. If a single table has errors, you can use the DBCC CHECKTable command to verify the problems. If you need to repair the entire SQL database, you can use the DBCC CHECKDB command.
There are 3 options to repair the database.
- REPAIR_FAST: This option is the fastest one to repair the database.
- REPAIR_REBUILD: This option repairs minor errors by rebuilding indexes.
- NOINDEX: This option does not include the indexes.
- PHYSICAL_ONLY: This option checks only the physical structure of the database.
To repair the database, follow the below T-SQL commands:
ALTER DATABASE stellar SET EMERGENCY;
ALTER DATABASE stellar SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
DBCC CHECKDB (stellar, REPAIR_REBUILD) WITH NO_INFOMSGS, ALL_ERRORMSGS;
ALTER DATABASE stellar SET MULTI_USER;
These commands set the database to emergency mode and single-user mode, and then repair the database. After that, you need to change the database to multi-user mode.
Use a Third-Party Tool to Repair the Database
Another solution is to use a third-party SQL database repair and recovery tool, such as Stellar Repair for MS SQL. This software can repair the database and recover all its objects. Here?s how to use it:
Before proceeding, you can set the database to offline mode.
ALTER DATABASE stellar SET OFFLINE;
Once it is set offline, create a copy of the data file.
Download and install the software. Once installed, open it.
The software requires you to select the SQL Server database file.
Press the Browse button and select the data file copy. Then, press the Repair button.
Once repaired, you can save the repaired data in a New Database, a live database, or other formats.
Conclusion
Above, we have mentioned different ways to fix error 3457 in SQL Server. You can restore the database from backup or repair the database using the DBCC CHECKDB commands. In case the backup is not available or not recent, then you can use Stellar Repair for MS SQL to repair the database and recover all its data with complete integrity.
