MS SQL Server Error 823: A Comprehensive Guide

In this article, we are presenting information regarding SQL Server Error 823, including the contributing factors of it and how to resolve it. You could try using an SQL tool to resolve systematic problems with the database that reported the 823 error.

Know the Background History of MS SQL Server Error 823

The SQL Server Error 823 occurs due to the Input/Output error detected during the (read or write request) failure. This is usually the result of hardware and software faults. Due to the system crashes or lost power while information is still being written to the disk.

Reason to Encounter SQL Server Error 823

• The damaged hardware objects such as Hard drives, Disk controllers, and data cables can be responsible for the SQL Server Error 823. Old hardware components sometimes cause overheating, which can also be the reason for hardware faults.
  
  
• Due to the power cut, the system shut abruptly during the MS SQL Server Database opening due to SQL Server Error 823.
  
  
• While reading or writing on the disk controller, the Input/Output logical check can fail during the system running.
  
  
• The malware attack on the SQL Server can also be the reason responsible for SQL Server error 823.
  
  
• Data corruption in software such as bugs, faults, and errors can cause SQL Server error 823.
  
  
• MS SQL Server update from the old to a new version can generate the SQL Server error 823.
  
  
• Updating an SQL Server account can also lead to SQL Server Error 823.

Manually Solve MS SQL Server Error 823

In this section, we are illustrating two manual techniques to resolve SQL Server Error 823.

Method 1

To address this error, the first step is to run the DBCC CHECKDB command and then proceed to resolve the database using the query

DBCC CHECKDB (DB_NAME, REPAIR_REBUILD);

To ensure the database correction, it is essential to restrict access to Single-User mode.

ALTER DATABASE DB_name SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

Method 2

An alternative manual method for resolving the SQL Server Error 823.

1. First, scan the MS SQL Server database for any shady pages.
   
   
2. Then confirm the accuracy of the SQL Server database.
   
   
3. If an error occurs, execute the “DBCC CHECKDB” query.
   
   
4. After that restores the SQL database from the backup data file.
   
   
5. In the end, examine the “Windows Application Event Log” to analyze the root cause.

Cons of Manual Method

• The whole manual process can take considerable time for the instantaneous answer.
• Need to know the technical knowledge of SQL command and structure.
• The possibility of loss of information was very significant in the manual process.
