Resolving SQL Table Error: Cross Object Linkage

SQL Server uses index information so that if you process a query that could fetch quick results. These are created on table columns. An index is basically comprised of various pages, arranged in the form of a B-tree structure. So, as you execute a query, the engine starts navigating from the root node and continue through the intermediate nodes till the leaf node is reached. Any malfunction in this index structure might introduce table corruption errors. Such situations require you to restore the data from backup or use SQL Repair utilities that could repair the database and its components effectively.

You might encounter the below table error with your SQL Server database:

“Table error: Cross object linkage. Page P_ID1->next in object ID O_ID1, index ID I_ID1 refers to page P_ID2 in object ID O_ID2, index ID I_ID2 but is not in the same index.”

This error is marked as error 8982 in SQL Server error log with severity level 16.

Cause

An SQL Server table results the above error if the two pages (P_ID1 and P_ID2) have been marked with dissimilar index and/or object information though they have been marked as linked.

Note: If you observe these problems persistently occurring, the possible reason is hardware malfunction.

Solution

Such table corruption errors should be resolved by following these methods:

First, you need to analyze your system for possible hardware problems. You can deduce such problems through error logs of operating system, application and SQL Server™ . Try to fix such problems, if any.
If you have valid data backup available, you need to restore your lost data from it.
If issue persists because of unavailability of clean data backup, you can run DBCC CHECKDB command that will let you know the exact repair clause that could fix this corruption. Execute DBCC CHECKDB command using the recommended repair clause.
Applying the above measure can cause data loss. Thus, for better and safe SQL Recovery, you should use third-party tools to scrutinize and repair damaged SQL Server databases. SQL Repair applications are built with powerful technology to assist database recovery in each possible case of corruption.

SQL Recovery is a comprehensive tool to repair damaged SQL databases for SQL Server 2008, 2005 and 2000. With self-descriptive interface, advanced repair options and read-only design, it is an effective SQL Repair tool to repair and restore all database objects. The software is compatible with Windows Vista, XP, 2003, 2000 and NT.
