One such corruption error is Schema Corruption error. Schema is the logically grouped SQL Objects like the tables, view stored procedure and other related elements of the database. When the scheme is generated user can access the database in a more effective and proper manner.
This error is mainly caused in SQL server when the server table is getting updated.
If you are working on SQL Server and while updating some tables you find possible schema corruption error message as given below:
“Msg: 211, Level 23, State 51, Line 1 Possible schema corruption.

The reason behind the schema corruption can be attributed to many factors, some of them are given below:
So, now let us take a look at the best solutions that you can to resolve Schema error 211.
Out of the various methods explained below, you can choose the method according to your usability. Following are the all possible solutions to troubleshoot this error:
One of the easiest and the best possible way to resolve this error is to restore from the backup files of the database. In addition, go through the following scenarios that will help you in restoring backup files:
If a user has a backup of the transaction log, then take a backup of the tail-log and restore the latest backup completely with entire transaction logs that are ending with tail-log backup. In such a case, the result will become in 0 data loss.
If you do not have a backup of the transaction log then, develop a new database and import more data as possible. You can also try to find out the corrupt table and then drop this table to recreate it again.
In this approach, you need to repair the entire MDF database file and then deploy the database again.
The last manual trick that you can use is to execute DBCC CHECKCATALOG command on the SQL Server.
After running the DBCC command the error will be displayed. For using this command, make sure, a user will get a suitable suggestion from SQL server database by running DBCC CHECKCATALOG syntax. By running this command users will get to know the location and reason behind the SQL server error 211. However, DBCC CHECKCATALOG signifies no error, but it is not possible at all times, so you need to confirm that.
If all the above methods fail to solve this error, then you can try using the MS SQL File Repair Tool. This tool guarantees 100% recovery even if you don’t have the backup file or it is corrupted.

So, you can try this professional method.
In this post, I have tried to explain the perfect solutions to troubleshoot Schema corruption Error 211 in SQL Server. Well, the best solution is to always keep the backup of the files. As these can be restored in case of any corruption in the database. But, if there is no backup, then you can follow the other methods stated above.
