Table Error Post Metadata Structure Corruption

MS SQL Server database is build up of various metadata structure components like

, pages, extent, etc. Pages are the smallest unit of data storage that store actual data. A combination of 8 adjacent pages makes an Extent. Corruption or damage in metadata structure primarily results in inaccessibility of records stored in your database. In most of the database corruption situation, you encounter an error message stating the cause for the error. For successful access of records stored in your database and overcoming hazards created by error message, an easy way is to restore the database records from an updated backup. But if in case, your backup file has been corrupted, damaged, or unreadable, then you will need to use advanced repair software that can comprehensively repair MDF files.

Consider a practical case, where you encounter the below error message when you attempt to access the records stored in your MS SQL Server database:

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

The above table error message primarily results in inaccessibility of records stored in your database. Furthermore, the error message reappears each time you attempt to access the database.

Cause:

The fundamental reason for the occurrence of the above error message is corruption of metadata structure (in this case, Extents). Extent corruption can occur due to various reasons, such as, improper system shutdown, virus attack, human error, and more. Te corruption can also occur due to various physical damages in your hard drive, like accidental dropping of hard drive, natural disasters, power spikes, and more.

Resolution:

To stop the error message from occurring and to make your records accessible, you will need to use follow underneath steps:

In case of metadata structure corruption due physical crash of hardware, change the old hardware with new one.

For metadata structure corruption caused due to logical crashes, run DBCC CHECKDB command (with recommended repair clause).

After using the above measures, there is a very dim possibility for popping of above error message. However, if it does, you will need to use a powerful mdf repair software to repair your database. These MDF Repair tools are extremely user-friendly as they are built with highly graphical user-interface.
