Using the indexes in SQL databases is a good practice as it makes searching the records faster and easier. The indexes consist of various pages that are arranged in the form of B-tree structures. When a query is executed, the database engine goes all way from the root node to the exact branch where the data is located. Any discrepancy in this routine may result in corruption of the database table. Such discrepancies can arise due to various reasons such as virus infections, hardware incompatibility, corrupt operating system, etc. You should use appropriate corrective measures to rectify the problem. However, if you are not able to resolve the issue then you should use a third-party mdf database repair
software to repair SQL database table.
Consider a scenario wherein you face the following error message while working on the SQL Server 2000 database.
"Table error: Cross object linkage: Page P_ID1, slot S_ID1, in object ID O_ID1, index ID I_ID1 refers to page P_ID2, slot S_ID2, in object ID O_ID2, index ID I_ID2."
The root cause of this error message is that the P_ID1 page is pointing to a different object in the P_ID2 page.
To resolve this error, you should perform the following methods, ideally in the given order:
Check for hardware issues: You should run hardware diagnostics and check the error logs to ascertain whether the error has occurred because of any hardware problem.
Also, you can swap the hardware components to isolate the error. In addition, you can consider reformatting the hard disk and reinstalling the operating system.
Restore from backup: You should check if the backup is updated and clean. If yes, then you should restore the database from its backup.
Run DBCC CHECKDB: You should run DBCC CHECKDB without the repair clause to know the level of corruption. Then, run the command again with the suggested repair clause. This command is used to check the logical and physical integrity of the corrupted database.
The aforementioned methods would be able to resolve the issue. However, there are times when you are not able to fully repair the database using these methods. In such cases, you should use a third-party SQL repair software to repair SQL database. Such read-only tools use fast yet sophisticated scanning algorithms without overwriting the original database.
