Table Corruption Post Meta data Structure Damage

Tables in MS SQL Server database act as a major storage component to save records with different data types. The data stored in the tables can be easily viewed by running a query. However, in some situations (when you receive an error message), the query may not display the desired records. One of the main reasons for the occurrence of the error message is corruption of table. The error message message halts the extraction of records, making them totally inaccessible. To access the records stored in the table, an easy way is to restore them from an updated backup. However, if the backup is not available, then you will need to repair the corrupt table. To do so, you will need to search for an advanced SQL Recovery application.

Picture a situation, where you receive the below error message when you attempt to access the records stored in a MS SQL Server database table:

“Table error: Object ID O_ID, index ID I_ID. Index node page P_ID1, slot S_ID1 refers to child page P_ID2 and previous child P_ID3, but they were not encountered.”

After the above error message appears, all the table records become inaccessible. Furthermore, the error message appears at every attempt of accessing the table records.


The above error message pops up when the table gets corrupted due to metadata structure damage. The result of damage is that the index page in a B-tree can not see its child references, which are neighboring to its two lower pages.

Note: Database corruption can either be caused due to logical or physical factors.


For systematic resolution of the above error message and repair of corrupt table, you will need to follow underneath measures:
Physical damages can be surmounted only by changing the damaged system object with a new object.
Logical corruption can be surpassed by running DBCC CHECKDB command.
In case the problem persists even after running DBCC CHECKDB command, then you will need to repair your database table using an advanced SQL Database Repair software.

A SQL Database Recovery utility ensures comprehensive repair of corrupt database components by incorporating powerful scanning methods. In addition, these tools perform safe repair, without making any changes in original records saved in table.
