When you run the Repair Database command, you may receive
the following error message:
isn't an index in this table
NOTE: This same behavior may occur
in Microsoft Access 97 with databases that are converted from Microsoft Access
7.0. If this happens, you should either:
Create a new database in
Microsoft Access 97 and import all the objects from a backup copy of the
Microsoft Access 7.0 database.
Use Jetcomp.exe, a
stand-alone utility, to compact the database.
The MSysObjects system table is corrupted.
If you receive the error, the database is corrupted beyond
repair. The Repair Database command cannot fix the file. The only resolution is
to restore a backup copy of the database.
To prevent this error in
the future, install the update of the Msjt3032.dll file. For more information
about obtaining this update, please see the following article in the Microsoft
Knowledge Base: 151186
ACC95: Updated Jet DLLs
Available in Download Center
For more information about obtaining
Jetcomp.exe, please see the following article in the Microsoft Knowledge Base:
ACC97: Updated Version
of Microsoft Jet 3.5 Available for Download
Microsoft has confirmed this to be a problem in Microsoft
Jet database engine version 3.0. We are researching this problem and will post
new information here in the Microsoft Knowledge Base as it become available.
Every Microsoft Access database contains system tables that
store information about the various objects in the database. The Microsoft Jet
database engine automatically creates the system tables, such as MSysObjects,
when you create a new database. If the MSysObjects table becomes corrupted
beyond repair, the database is unusable and will not open.
error is usually preceded by symptoms that indicate problems with your
- Duplicate table names appear in the database.
- Tables appear that you do not have permission to delete,
even though you have administrator level security permissions in the database.
- Tables appear that are owned by <Unknown> or Engine.
If these symptoms occur in your database, follow these steps:
- Back up the database.
- Run the Compact Database command.
- Run the Repair Database command.
- Import the undamaged objects into a new database.
