Resolving “ isn't an index in this table” Error in MS Access

Are you unable to access the database due to missing or corrupt index entries? This behavior renders your valuable data inaccessible and you cannot use the data stored in the database and all of its objects or components become unusable. This behavior may lead to critical data loss situations. In order to get your mission-critical data back, you need to opt for access database recovery solutions, if an updated backup is not available.

In a practical example, when you try to access the database or attempt to repair it through Repair Database method of Compact and Repair utility, you come across the below error message:

“'database name' isn't an index in this table. Look in the Indexes collection of the TableDef object to determine the valid index names.”

This error message terminates the repair process and database remains in corrupt state. In order to gain access of the database in such circumstances, identify the cause of this issue and Repair Access File by sorting it out.

Root of the issue:

You come across this behavior due to any of the below behaviors:
An index is missing from MSysObjects table of Microsoft Access. It may occur if you abort the repair process.
MSysObjects system table is damaged.

Every MS Access database uses system tables to store information about various database objects. The system tables are automatically created by Microsoft Jet database engine. If MSysObjects table of your Microsoft Access database gets damaged, database cannot be opened and used.


The above behavior shows that database is damaged beyond repair through the “Repair Database” command. Follow the underwritten steps to fix the issue with an alternative method:

Backup your MS Access Database.
Run Compact Database command.
Import undamaged objects in new database.
Restore the database from updated backup.

In case the backup is either not available or its not updated, access repair through third-party applications become need of hour. They are able to handle all types of database corruption scenarios very effectively.

The Access Database Repair applications use high-end scanning techniques to systematically scan whole damaged database and extract all inaccessible data from it. The applications come equipped with simple and rich graphical user interface to provide easy recovery. They preserve integrity of your database due to their read-only conduct.

Access Recovery is an advanced utility that offer absolute recovery in all cases of database corruption. The software works well with Microsoft Access 2007, 2003, 2002, and 2000. It restores all database objects, such as tables, reports, forms, triggers, store procedures, and constraints.
