While working on your SQL Server database, sometimes the database tables become completely inaccessible following any corruption or damage to the database. The reason behind the corruption can be virus attack, file system corruption, application malfunction, simultaneous access by the number of users beyond the upper load limit etc. In any of these situations, the database flashes some sort of error message, which points toward a possible problem with the database. You need to resolve the error to regain access to the database tables. However, if you failed to resolve the issue, there are third-party SQL database recovery tools available, which can help you recover the database back.

The error message that you may have encountered can be read as below:

“Table error: Extent P_ID object ID O_ID, index ID I_ID is beyond the range of this database.”

After encountering the error message, you can not be able to access any record from the SQL database and receive the same error, each time you try to access any table...

Microsoft SQL Server database supports binary tree indexes for fast query. The pages of Binary tree index are known as index nodes, the top node of binary tree is known as root node. However, the middle nodes are known as branch nodes and bottom nodes are known as leaf nodes. If table indexes get damaged, SQL Server database shows an error message and you unable to access your SQL database. To resolve such situations, you should use your most latest backup and restore the lost data. Sometimes, backup fails to restore the database and thus, you need to use SQL database recovery software.

You are working on SQL Server database wherein, You might get below error message:

Server: Msg 8936, Level 16, State 1, Line 1 Table error: Object ID O_ID, index ID I_ID. B-tree chain linkage mismatch. P_ID1->next = P_ID2, but P_ID2->Prev = P_ID3.

Root Cause of Problem:...

Sometimes when you want to update or delete SQL server database table and got an error message that shows your SQL server database table has been corrupted. This may happen by the several reasons some of them are improper system shutdown, virus attack, hardware failure, power failure and many more. At this situation you will be unable to access your SQL server database table. For fixing this problem you should use an advanced SQL server recovery software that will repair and restore your damaged SQL server database table.

Consider a practical scenario wherein, you may encounter the given below error messages while your are trying to update, delete or open an SQL server database table:

“Error: 644, Severity: 21, State: 5 Could not find the index entry for RID '1613b1000000100' in index page (1:189), index ID 7, database 'TestDB'.. Error: 8646, Severity: 21, State: 1 The index entry for row ID was not found in index ID 7, of table 2009058193, in database 'test644'.”...

Are you facing assertion failure errors, while executing queries on MS SQL Server 2008 or 2005 databases? Does the query execution process fail halfway and you encounter errors? You may face the assertion failure problems due to either software bug or Master Database File (MDF) corruption. In both the cases, you can not access the database and come across data loss situations. In order to extract data in these circumstances, restore the database from backup. However, if the backup is unavailable, Master Database File Recovery becomes essential.

For example, the process may fail when you execute a distributed query, which uses linked server in MS SQL Server 2008 or in MS SQL Server 2005. Furthermore, you come across the below error message:

"OLE DB provider "SQLNCLI" for linked server "Linked Server" returned message "No transaction is active.". Msg 3624, Level 20, State 1, Line 1...

Allocation of MS SQL Server table data can be done either in B-tree or in heap structure. Data retrieval from a heap structure is slow as compared to retrieval from B-tree structure, which is very fast. B-tree structures minimize the navigation of your record, thereby resulting in fast retrieval of your data. B-tree structures use leaf nodes as storage components to save table records. Records saved in MS SQL Server table become inaccessible if these leaf nodes are missing, damaged, or not pointing to the correct parent node. In most of these situations, a database user encounters an error message. To overcome such error messages and to access table records, users can restore data from an updated backup. However, if no backup is available, then the user needs to opt for SQL Repair solutions.

To elaborate the above scenario, consider a realistic situation, wherein, you encounter the below error message while trying to access table records:...
