The fast results of SQL queries is a result of b-tree indexes used by a SQL Server. A single B-tree consists of number of index nodes, root nodes, branch nodes, and leaf nodes that enable you to systematically store your data.
Corruption in any of the nodes (specially index nodes) can result into inaccessibility of records stored in the database. In most of these situations, you encounter an error message stating the exact cause. To surpass the above database inaccessibility circumstances, you will need to use restore the data stored from an updated backup. However, in absence of an updated backup or backup falls short to restore the required data, then you will need to search for advanced third-party sql repair application.
Consider a practical scenario, where you receive the below error message when you attempt view the records saved in your SQL Server database:
Table error: Object ID O_ID, index ID I_ID. B-tree chain linkage mismatch. P_ID1->next = P_ID2, but P_ID2->Prev =P_ID3.
After the above error message appears, the data stored in the database becomes inaccessible. Moreover, you receive the same error message each time you attempt to access the database.
Cause
The root cause for the occurrence of the above error message is the break in the logical page chain at any level (root or leaf) of B-tree. This scenario can occur due to various logical or physical factors.
Resolution
For absolute resolution of the above error message caused due to either logical or physical reasons, you will need to follow the below measures:
