How To Resolve System Table Mismatch Error In SQL Server

by: Mark Willium

In Microsoft SQL database, there is some value (data) in the metadata structure that describe each and every table. These values change due to metadata corruption that can result in inaccessibility of data saved in the SQL Server table. Some causes for metadata structure corruption are SQL database damage, mallware function, power failure and human errors. Once the table is damaged, an error pops up describing the cause for the corruption. To surpass the error and to access the SQL database table records, you need to restore the records from an updates and latest backup. However, if in case, the latest backup fails to restore the desired records, then you will need to use an advanced SQL recovery application to repair the damaged table.

Consider a scenario, wherein the below error message pops up when you attempt to access a SQL database table:

“System table mismatch: Table 'O_NAME' object ID O_ID has index id 1 in sysindexes but the status in sysobjects does not have the clustered bit set. The table will be checked as a heap.”

Since the error message appears while trying to read the records of SQL table, the records saved in the table become inaccessible mode.

Root cause of corruption:

The above error message occurs when the metadata structure describing the table gets corrupted.

Way to solve:

For resolving above error message you can follow provided steps below:

To resolve the SQL table error, if caused due to physical corruption of a system component, you will need to change the damaged system with a new one.

The above error message, if caused due to logical corruption, you can be resolved by running DBCC CHECKDB command with correct repair clause. However, if the above error persists even after running the repair command, then you will need to opt for SQL repair tool for repairing the table.
