Resolving Table Error in SQL Server database

A table error while accessing a table in SQL Server 2000 database can occur due to various reasons like corruption in page header, incorrect alignment of system table, invalid page type, index_page page has an index zero, incorrect header modification, hardware failure, and more. While the reasons for table corruption might be many, but the result for all them remains the same – inaccessibility of table records. To access the table records without applying any extra efforts, you can directly restore the table from an updated database backup. However, if the database backup is not available or backup falls short to restore the data, then you will need to use advanced MDF Recovery software to resolve the corruption and access the records.

As a practical scenario, you receive the below error message when you try to view the records stored in the table:

“Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Values are VAL1 and VAL2.”

The error message re-appears each time you attempt to access the records saved in that table. In addition, the error message makes the records stored in the database becomes inaccessible.


The various causes of the above error error message are discussed below:

Damage in page header
Incorrect alignment of system table
Invalid page type
Hardware Failure


To resolve the above error message caused due to hardware failure, you will need to run the hardware diagnostics. Fix the hardware problems by by swapping the hardware components.
To resolve the error message caused due to software failure, in case you have not maintained any database backup, you will need to execute DBCC CHECKDB command without a repair clause. This helps you to identify the exact cause for database corruption. After identifying the cause, execute the correct repair clause to repair the database.
Note: Running the DBCC CHECKDB command with repair clause might result into loss of data.

In most cases, the error message gets resolved after running the DBCC CHECKDB command. But if in case, the command fails to resolve the error message, then you will need to opt for powerful MDF Repair software. These SQL Server Recovery applications use high end scanning methods to repair the corrupted SQL Server database and restore them on the user-specified location.
