Corruption in MS SQL Server table is mainly caused when the metadata structure of the database gets damaged. Few major causes of metadata structure corruption are improper shutdown of system/database, application malfunction, and malicious software like virus. The data saved in the corrupted table cannot be accessed. For accessing the table records, the database user needs to restore the table from a valid database backup. But if in case, the valid backup does not the desired table, then the user needs to use advanced
MDF file recovery application that can comprehensively repair the table and allow the user to access its records.
To illustrate the above case, consider a scenario where you receive the underneath error message while trying to view a specific table records:
“Table error: Object ID O_ID, index ID I_ID, column 'COLUMN'. The column ID COL_ID is not valid for this table. The valid range is from 1 to MAX_COL_ID.”
The above message appears every time you try to access the table. Additionally, the error message makes the records stored in the table inaccessible.
Cause:
The above error message primarily appears when the metadata for the table consists of a column ID, which is greater than the largest Column ID used in that table. This occurs when the metadata structure is corrupted. The above table error message can occur either due to physical or logical corruption.
Resolution:
Follow the below steps for resolving the table error message and accessing the table records:
To repair the database damaged due to physical damage, you will need to change the damaged component with a new one.
Running DBCC CHECKDB command with appropriate repair clause allows you to repair a logically corrupted database.
However, if the DBCC CHECKDB command fails to resolve your issue, then you will need to download MDF File Recovery application from the Internet.
Master database file recovery software displays all the repairable database component records and allows you to restore the component on your desired location. The repair process is easy to understand as the software comes with an interactive user-documentation.
