This problem can be clearly understood by a real-life scenario.

“Please help me! I got an error message ‘Possible index corruption detected. Run DBCC CHECKDB. (Error 9100 in SQL Server)’. I have almost 2 TB of database in Microsoft SQL Server. I have been trying to fix this error with the help of DBCC CHECKDB command. But, it takes lots of time to execute. So, I urgently need a quick way to resolve MS SQL Server Error 9100.”

In the subsequent sections, we are going to discuss some suitable methods that can fix SQL index table and remove error code 9100.

Techniques to Fix Microsoft SQL Server 9100 Error

In the following section, readers will understand two manual approaches in order to fix SQL error. So, let’s begin with the first method.

Method #1: Use DBCC CHECKDB

DBCC CHECKDB command is the first preference of a user to resolve any error in SQL database. The function of this command is to find out physical and logical integrity of all objects in the database. When the user executes this database command, the below listed parameters is checked in the database:

  • Check logical data consistency on a single table
  • Correct arrangement of indexes
  • Proper connection of indexes & data pages
  • Uniformity among pointers
  • Suitable volume of page offset

The following commands are required to check the logical and physical integrity of objects in particular database are as follows:

  1. DBCC CHECKALLOC – This T-SQL function is to verify the consistency of memory space allocation structure of a database.
  2. DBCC CHECKCATALOG – This command work is to check the consistency of catalog for a specified SQL database.
  3. DBCC CHECKTABLE- This command is used to investigate all the structures and pages that create index table in SQL Server.

Important Note: All of the above-discussed T-SQL commands executes automatically when DBCC CHECKDB commands runs on the console.

Method #2: Regain Data From Backup

It is possible that the SQL error code 9100 will not be removed by DBCC command. So, the next step is to extract data from backup file. In such a situation, when the database is restored from the recent backup files, only the current data will not be recovered and rest of them will be retrieved easily. Below are some points that need to keep in mind while taking backup:

  • Take backup of SQL database on regular basis.
  • Backup file must be stored in safe location that has minimum access.

Shortcomings of Manual Approaches

Almost all manual workarounds are free of cost. But, they come up with some downsides. Yes! you heard it right. So, it is always advised to first look at the limitations of manual method, then use it at your own risk. In a similar manner, the above-described traditional approaches have some demerits that must be known to the users. The following negative points of manual techniques are listed below;

  1. In case, when users have large database, then DBCC CHECKDB command takes lots of time to rectify the error.
  2. It is must to have proper knowledge of T-SQL before using the manual techniques.
  3. Any mistake while writing a query can make the situation worse.
  4. In the absence of backup file, users cannot use the second manual method.

Quick Way to Fix SQL Server Error Code 9100

  • It is evident from above that users need to face various problems while using manual techniques. So, it is better to have a solution that is easy to use and error-free.
