DBCC stands for Database Consistency Checker. It acts as database console commands which means they are used to check the consistency of the SQL server database. They maintain databases, tables, file groups, and indexes. It also checks the logical and physical integrity of all the objects in the specified database by performing the following operations:
If you have ever run DBCC CHECKDB, you must know that it takes some time for large databases.
Data corruption can cause all sorts of issues within the database. It may include incorrect data results and failed SQL statements, and in some cases, it takes down the entire SQL instance. Therefore, DBCC CHECKDB warns you of corruption so that you can fix it before it gets too bad.
It is quite simple, you just need to run the below statement, and the basic syntax looks like this:
DBCC CHECKDB (‘DatabaseName’)
But obviously, you don’t want to log in every morning and run this statement on each database, so you must automate this process using a few different methods.
Do not panic; just check backups. DBCC CHECKDB errors usually indicate what needs to be done.
If you do not have a backup, then you may need to use DBCC CHECKDB with a repair option. So, here are the repair options that are available to use. They may or may not work and should be used as a last option.
Yes, of course, an alternate solution exists when Repair_Allow_Data_Loss does not work. Correcting errors by using the REPAIR_ALLOW_DATA_LOSS clause can result in data loss. So, to prevent data loss, you should make use of an automated tool.
Sysinfo SQL Database Recovery provides the facility to recover the file objects, including tables, views, stored procedures, programmability, triggers, default, and functions.
It saves the recovered data in the SQL Server database or a compatible script format. It also supports SQL server compressions and deals with SQL Server corruption with great ease.
Through this blog, we understood what DBCC CHECKDB does and how it helps to repair a SQL Server database. Above, I have also described the automated tool that can recover data from the corrupt SQL server database files and restore it into SQL Server and SQL compatible script. Hope it helps.
