The command DBCC CHECKDB is used to check the physical and logical integrity of all the objects in the mentioned database. To do that, it performs the following operations:
* Runs DBCC CHECKALLOC on the mentioned database.
* On every table and view in the database, the DBCC CHECKTABLE command is executed.
* Runs DBCC CHECKCATALOG on the database.
* Then it validated the contents of every indexed view in the mentioned database.
* It also validates link-level consistency between file system directories and table metadata while storing varbinary(max) data in the file system using FILESTREAM.
* Finally, it validates the Service Broker data in the database.
So, you just have to execute the DBCC CHECKDB command, and automatically, DBCC CHECKALLOC, DBCC CHECKTABLE, or DBCC CHECKCATALOG commands get executed.
Also, note that DBCC is supported on databases that contain memory-optimized tables but does not provide repair options. This implies that you must regularly back up databases and test those backups.
