Database Repair post “Table error: Page P_ID...” Error Message

Two main building blocks of every MS SQL database are pages and indexes. These pages store actual data and are always marked by a header that stores information such as, page number, page type, and free space. The page type in header section saves the data (Index, allocation map, etc.) that define the page. Corruption in the header might occur due to numerous factors, resulting into inaccessibility of records stored in the database. In most cases of SQL database corruption, you encounter an error message. To surmount the error message and access the SQL database records, you will need to restore the data from an updated backup. However, if the database backup file is corrupted, damaged, or inaccessible, then you will need to use advanced SQL Repair software.

Below is the error message that appears after the header gets corrupted or damaged:

“Table error: Page P_ID with object ID O_ID, index ID I_ID in its header is allocated by another object.”

The above error message appears every time you attempt to access the database records. In addition, the database records become inaccessible after the above error message appears.


The above error message primarily occurs when a page contains a Index ID but is not allocated by any of the index's IAM pages. This happens in case of Index corruption, caused by either logical or physical crash.


Underneath are the resolutions for database repair caused due to logical or physical issues:

For logical crash circumstances, run DBCC CHECKDB command (with recommended repair clause) to repair your database.
For physical crash situations, examine the application and Microsoft Windows system logs. These logs enable you to determine the hardware responsible for damage. Swap the damaged hardware with a new one.

While physical damages can be convincingly solved by changing the hardware component, DBCC CHECKDB does not provide comprehensive repair in all cases. To repair your database is such situations, you need to have an advanced SQL Repair software. Such SQL Server Recovery software ensure complete repair after all the logical corruption scenarios by using intensive scanning and repairing techniques.
