Damaged MSysObjects Table Cause Access Database Corruption

Microsoft Access stores your valuable data in MDB (Master Database for Access 2003 or earlier) or AccDB (Access Database for Access 2010 and 2007) database in the form of tables. A database table is a collection of elements that is managed using a pre-defined model of the vertical columns and the horizontal rows. Access database tables consist of various objects, which are used for different purposes. The major objects include reports, forms, macros, triggers, stored procedures, constraints, and user defined functions. If one or more of the Access database objects are corrupt, you may encounter serious data loss and MDB repair solutions become need of hour.

Microsoft Access System Objects comprise of a number of tables, which provide you significant information about MS Access database. One such database table is 'MSysObjects' table. It offers you comprehensive information about Microsoft Access database objects (such as forms, macros, and queries) that may come in pretty handy while documenting your MDB or AccDB database. In order to gain access to the system objects, you need to set the 'View/Options/ General/Show System' objects as 'yes'.

When you update the databases of your clients, you may regularly use 'LastUpdated' query with changed or new database objects. You can generate the list of changed or new Access database objects by creating a new query and then entering the below SQL statement to it:

SELECT MSysObjects.DateCreate, MSysObjects.DateUpdate,
MSysObjects.Name, MSysObjects.Type
FROM MsysObjects;”

In case the MSysObjects table gets damaged, you can not access your database objects and thus the database may become inaccessible. After corruption of the objects table or database objects, you may find that the database may not perform properly.

MsysObjects table of Access database may corrupt due to any of the following reasons:
  • Access database itself is corrupt.
  • Application malfunction or improper termination of MS Access program.
  • Virus infection or spyware attack.
  • Improper system shutdown or operating system crash.
  • File system or storage media related errors.
  • Concurrent updating of same Microsoft Access database over network.
In such cases, you need to repair MDB file to get your valuable data back. It is possible to easily repair and restore damaged Access database using powerful and effective third-party applications, known as MDB file repair software. The applications repair MDB database in all corruption scenarios using high-end database scanning techniques.
