The master data file (MDF), the transaction log data file (LDF), and the next data file make up the SQL database (NDF). For rollback purposes, it retains all data and records all the way down to the SQL database. Along with MDF and NDF files, Log files are a crucial component of the SQL database and have a direct impact on how well the SQL server functions. Any issue with a file in the SQL database will cause the SQL server to stop functioning.

So, we’ll talk about manual and contemporary methods of fixing SQL databases. Let’s begin by comprehending the potential reasons for this problem, which are discussed in more detail in the piece that follows.

There aren’t many manual fixes for corrupt SQL databases, and even those don’t always result in database recovery. However, using this process you can restore minor damages in your SQL server. So without any delay let’s get started.


Before running DBCC CHECKDB to run consistency checks on a database or repair it, make sure your system complies with the requirements listed below.

  • Your computer needs to have SQL Server Management Studio (SSMS) installed.
  • The user needs to be an administrator.

Detailed Procedure to Use DBCC CHECKDB to Repair SQL Server Database
