MDF database recovery utility to deal with Table error Extent P_ID range of this database

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.

Causes: The above error tells that the size of the pageinfile of the SQL database has been greater than the physical size of the filenum. Here, the P_ID is the PageID of the filenum:pageinfile form. This is the reason behind the error and may have been occurred due to a possible metadata structure corruption.

Resolution: In order to resolve the problem, you have to run the DBCC CHECKDB command with appropriate clause. This will repair the corrupt database.

If you failed to resolve the problem, you have to look for your backup server for any available valid backup. But, if you have not taken any backup recently or there occurs any error while resolving the problem, you are left with a single choice of running any mdf database recovery software.

These mdf file recovery utilities are designed with powerful algorithms to repair the database and recover various objects, including the tables, views, forms, containers etc with ease. These SQL recovery applications are completely read-only in nature and do not modify the database by any degree. Moreover, with the highly interactive graphical user interface, any user can use the software and retrieve his data without even any further assistance.
