MS SQL Server Database is one such thing that is widely known for its versatility and advanced functionality. This is largely used by organizations, institutions, industries, and businesses for storing and managing the data in a wide range. At some point, the SQL database gets corrupt, which damages the metadata in the SQL Server. However, fixing this corruption is really essential otherwise all the data in SQL would be at high risk.
What is Metadata in SQL Server?
In simple words, we can say metadata is data about data. Usually, the metadata returns the information about the database, DB objects, DB files, etc., in MS SQL Server. In relational databases, metadata consists of the information regarding the schema, storage, etc.
The user can get all the information of the MS SQL Server database by running the sys.databases. For this, you need to execute the below-mentioned command:
Select * from sys.database;
There are numbers of functions in MS SQL Server that will return the information about the SQL database and database objects, which are known as Metadata functions. Some functions are given below:
INDEX_COL, OBJECT_ID, OBJECT_NAME, COL_NAME, OBJECT_NAME etc.
Reasons Behind Metadata Corruption
Some major reasons behind the metadata corruption are listed below:
- Accidental data deletion.
- Software updating from the old version to a newer version.
- Malware/virus attack.
- Sudden system shutdown or power failure.
- If data stored in a compressed folder.
- If the system, views, procedures, and functions get damaged.
How to Detect Metadata Corruption in SQL Server?
To check the corruption in the database, the DBCC CHECKDB is used. Run the following command to detect errors in the current database:
In order to identify corruption in metadata, simply run the DBCC CHECKCATALOG.
Now, this DBCC CHECKCATALOG will detect the corrupted objects in the current SQL database.
