Tips To Resolve table Error: Object O_id... Page P_id Was Not Encountered. Error

The records in Microsoft SQL Server database can be placed and located in the form of a B-tree

. These records are divided into various pages (child pages), each having a unique index page, which is one level up in hierarchy from the child page. Corruption in the hierarchical tree structure (metadata structure corruption) primarily results in loosing the reference of the child page from the Index page. In such situations, the data stored in the database becomes inaccessible. For accessing the data stored in the database, an ideal way is to restore it from an updated database backup. But if in case of absence of an valid database backup, you will need to use advanced MS SQL Database Recovery application to repair your database.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table:

Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered.

The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table.

Cause:

The root cause for the occurrence of the above error message is SQL database corruption due to metadata structure damage.

Note: SQL database can be corrupted either due to logical or physical factors.

Resolution:

To resolve the above error message and to access the table records, you will need to follow the below measures:

To solve all the corruption issues caused due to physical damage, swap the corrupt system component with a new component.

To solve all the corruption issues caused due to logical damage, run DBCC CHECKDB command with correct repair clause.

The first measure is competent enough to resolve all the physical damage issues. The second measure, however, fails to resolve all logical corruption problems. For such situations, the database table can be repaired by using advanced MS SQL Recovery software. These SQL Repair utilities employ effective scanning methods to completely repair the corrupt table after all logical database corruption scenarios.
