Resolving 'Msaccess can't open the table' error and repairing MDB file

MDB files are database files created by Microsoft Access, a pseudo-relational database management application which comes rolled up in MS Office suite of applications. MDB files often become corrupt due to factors like sudden power surges, improper system shutdown, poor database structure and others. These factors are responsible for forcing an Access database to exhibit abrupt behavior. If your crucial Access database file becomes corrupt despite the preventive measures you have observed, consider using the clean and updated backup copy. If a backup doesn't prove helpful or is not available due to any reason, you must think about using professional MDB repair software. These solutions help in repairing MDB files and ensure that data loss is minimized.

Consider a scenario, wherein, you are using an Access 2000 database in a multi-user environment. When you make an attempt to open a table, a query or a report from the database, which is stored on a network, you might receive the following error message:

"Record is deleted"

If the object is a table or query, you might also receive another error message which goes like:

"Msaccess can't open the table in datasheet view. "

As a result of the error message, you cannot access information from the Access 2000 database.

Cause
The error message can be encountered with an Access 2000 database due to the presence of a damaged object. Another prominent reason could be corrupt MDB file. The MDB file can become damaged when using an Access database two users try to modify a same record simultaneously and one of them quits the application unexpectedly or abruptly.

Resolution
To repair MDB file, you must observe the following steps:

•Go to Tools menu, in the Database Utilities, click Compact and Repair Database option
•Locate and click the affected MDB file in the Database to Compact from dialog box, and click Compact
•In the Compact Database Into box, choose a location for the new file and punch in a unique name in the File name box, and click Save.

If the MDB file is severely corrupt, you might not be able to address the problem by using the above-discussed method. In order to repair MDB file successfully, you must rely upon a specialized third-party application.

Troubleshooting database corruption in MS Access 2000 database

MS Access is used by millions of users over the world primarily because of its availability with the MS Office suite. Apart from this, it is also very simple to use and also not discounting the fact that it has got online support as well as forums to provide any kind of help. But still there are certain trivial issues like database corruption due to which it becomes difficult to work at. In these situations, there appears a serious need of using an MDB file repair software if the usual methods to repair MDB file do not work.

Taking an instance into consideration in which you are trying to open an Access 2000 MDB file but fail to do so. An error message is displayed in this regard, which is:

“The database 'filename.mdb' needs to be repaired or isn't a database file.
You or another user may have unexpectedly quit Microsoft Office Access while a Microsoft Office Access database was open.
Do you want Microsoft Office Access to attempt to repair the database?”
If you click on 'Yes' to repair the MDB file, then you would receive the following error message:
“Unrecognized database format 'filename.mdb'”
In the end, you click the 'OK' button to close the dialog box and the following informational message is displayed:
“The database 'filename.mdb' can't be repaired or isn't a Microsoft Office Access database file.”

Cause:
The root cause of this error is that the MDB file is damaged, which is why you are unable to access it. In this case, the MS Access Jet engine can identify the structures and definitions of the database. However, either the table data or table definitions are damaged.

Resolution:
To repair the MDB file, you should use the 'Compact and Repair' feature in MS Access. This feature is used to repair the errors in the MDB file by compacting the database. Try to access the database after using this utility. It should be open perfectly.

To overcome this tricky situation, I would recommend to use a professional MDB repair software to repair MDB file. These Access repair tools, having rich user interface, that use extremely safe but powerful scanning algorithms to repair MDB file.

Resolving corruption issues in an MS Access 2003 MDB file

MS Access uses the MS Jet (Joint Engine Technology) Database Engine to manage the commands to operate the Access database. It stores all the database data in an MDB (Master Database) file. Also, it offers the user interface to monitor and maintain Access MDB file. However, there are times when you are not able to use the Jet engine to perform various tasks such as compacting the database. Such problems may arise due to MDB file corruption. In such cases, you should use appropriate corrective measures to repair MDB file. If you are not able to repair MDB file, then you should use a third-party MDB file repair software to do the needful.

Consider a scenario wherein you are working on an Access database. You use Jetcomp.exe to compact the database, it fails to do so. An error message is displayed, that is:

“Records can't be read, no read permissions on MyDatabase.”

Cause:
The root cause of this error is that the database is either corrupted or damaged. Due to which, the MDB file is inaccessible.

Resolution:
To resolve this error and repair MDB file, you should perform the following steps:
  • Create a database having the structure of the problem database.
  • Paste the structure of the problem database to a new table.
  • Copy the table structure of the problem database table.
  • Open problem database table and click 'Datasheet View' on the 'View' menu and select all records.
  • Copy all the records from the problem database table.
  • Now, paste the records in the new table.
  • Follow these steps for all the remaining records in the rest of the tables.
  • Create a new database with a different name.
  • Import the new table to the new database.
  • Exit MS Access 2003.
  • Delete the LDB file of the problem database.
  • Rename the new database as the problem database. Now try to open the database again. The problem should be resolved now.
However, if you still facing difficulties in opening the database table then you should use a third-party MDB file repair software to recover the inaccessible data. Such MDB repair tools are read-only in nature that do not overwrite the existing database while scanning it.

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.

How to resolve Error 3011 in MS Access 2003

MS Access is an RDBMS (Relational Database Management System) from Microsoft that combines rich user interface and efficient database tools with MS Jet database engine. It is used by many users as it is available with the MS Office product suite. The information of the Access database is stored in its primary database file, MDB (Master Database) file. Sometimes the MDB file may get corrupt thereby making the database unable to display its proper functioning. Such situations can be raised due to various reasons such as virus infections, power outages, abrupt system shutdown while the database is open, bugs in MS Access version, etc. In such cases, you should repair Access database using in-place methods. If you are unable to repair MDB file, then you should use a third-party MDB file repair software to do the needful.

Consider a scenario wherein you are using MS Access 2003. When you try to open an Access database, you are unable to do so. An error message is displayed, that is:

“The Microsoft Access database engine could not find the object . Make sure the object exists and that you spell its name and the path name correctly. (Error 3011)”

Cause:
There could be the following reasons for the aforementioned error message:
  • The system (or user) object may not exist.
  • The object name is misspelled.
  • The system or user object is corrupted, which is why Access is unable to recognize it.
Resolution:
To resolve this problem, you should perform the following methods:
Check the object: You should check for the existence of the specified object.
Verify the spellings: You should check for the correct spellings of the specified object, and try to open the database again.
Repair the corrupted database: You should try to repair the database using the 'Compact and Repair' option.

These mentioned methods should be able to resolve the issue corresponding to each aforementioned reason. However, if you are still not able to open the Access database then you should use a third-party MDB file repair software. Such MDB repair tools use fast and sophisticated scanning algorithms that do not modify the existing database.

How to fix 'Record(s) cannot be read; no read permission...' error in MS Access

Tables are the building blocks of a Microsoft Access database. When you create a database, you store data in tables – subject-based list. A table contains records and fields. Each record (row) contains data about one instance of the table subject, such as a particular employee, whereas each field (column) contains data about one aspect of the table subject, such as employee id or e-mail. Thus, tables allow you to create the framework for storing information in an Access database. However, tables in MS Access also have the tendency to go corrupt in many instances including abrupt shutdown, virus attacks, application malfunction and others. In such situations, when data stored in tables become inaccessible, you must restore the damaged .mdb file from an updated backup. And, if there is no backup available, switch to an advanced mdb repair software.

Consider a scenario, wherein, you attempt to open a table with Microsoft Access database, and instead receive the following error which reads like:

'Record(s) cannot be read; no read permission on xxxx' (Error 3112)

xxxx in the above error refers to an Access object name. It can be either a system object or a user object.

In an MDB database, there are many system tables (called as system objects) containing vital information about the database. They remain hidden by default and are maintained by MS Access only. Access creates the following system tables when creating an MDB file:
MSysAccessObjects, MSysACEs, MSysObjects, MSysQueries, MsysRelationships

Therefore, you may also receive the error:

'Record(s) cannot be read; no read permission on MsysObjects.'

Cause
The above error can surface in the following conditions:
  • If you don not have permission to view data of the specified table or query
  • If the object information or data are partially corrupt
Resolution
You can observe the following steps to troubleshoot the issue:
  • Consult the system administrator or the creator of the object to change your permissions
  • If you are sure about the permissions, then you must opt for an mdb file repair utility in order to address corruption problem.
Such tools are available in abundance over the Internet. But, selecting a particular one could be an onerous task as it would require you to do proper analysis and research. Once selected, you can use an mdb repair tool to repair corrupt access databases in an effortless manner.

Recovering corrupt Access 2000 MDB file

MDB is the default file extension for most of the Access databases (except for Access 2007, which also supports ACCDB). It consists of various database components such as tables, queries, forms, stored procedures. You can import MDB file into various MS Office applications such as Word, Excel, etc. However, sometimes MDB files may get corrupt due to various reasons such as human errors, abrupt system shutdown when the database is open, virus infections, power surges, etc. In such cases, you should take appropriate corrective measures to repair the file and recover the data. However, if you are unable to resolve the issue then you should use a third-party MDB file repair software to repair MDB file.

Consider a scenario wherein you open a database in Access 2000. However, you are unable to do and an error message is displayed, that is:

“Unexpected error 35012”

Cause:
The root cause of this error message is that one or more components (such as forms, tables, etc) of the database are corrupted.

Resolution:
To resolve the issue and recover the trapped data safely from the MDB file, you should perform the following steps:
1.Create a new Microsoft Access database.
2.Import the database into the new database by following File | Get External Data | Import. Import all the database objects of the corrupted database to the new database.
3.If the aforementioned error message is getting displayed while importing a particular database object then repeat Step 2 and exclude that object this time. Restore that object from an updated and clean backup of the database.

However, if you are unable to address this issue using the mentioned method or the backup is not updated then you should use a third-party recovery tool to repair MDB file. Such read-only tools perform .MDB repair using fast yet sophisticated scanning algorithms without overwriting the original data.

Recovering MDB file after append query failure

MDB or ACCDB are database files which are created by Microsoft Access , widely used relational database management system (RDBMS). It contains database structure, database entries as well as data entry forms, queries, stored procedures and database securities. Microsoft Jet Database Engine stands rich graphical interface to access' s application to make it more user friendly and presentable. An .MDB file is always required to configure a Microsoft Access data source either by open database connectivity administrator or pro grammatically. What to do in such case if MS access MDB file corrupts due to some factors which can cause loss of file stability and thus, result in crucial data loss. This unstable situations can be resolved using third party MDB recovery software which is used to repair MDB file.

Consider a scenario where you are working on an MS Access database and you are supposed to add few records in a table and command is executed but at sudden an error message is displayed that is:

Microsoft Access can't append all the records in the append query.

Microsoft Access set 0 field(s) to Null due to a type conversion failure, and it didn't add record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations.

Do you want to run the action query anyway?
To ignore the error(s) and run the query, click Yes.
For an explanation of the causes of the violations, click Help.”

Cause:
There could be two majors reasons for the occurrence of this error message as follows:
1. Either Table consists of self-join and memo fields implemented with referential integrity
2. Or a table corrupts.

Resolution:
Such errors can be resolved by changing the Memo fields to Text fields. You can also move the Memo fields to another table and then use a 1:1 relationship between the tables. These methods can be used to resolve these issues. However, if it is showing error then table is corrupt. In such case, you can use a third-party MDB repair software to recover Access table. These read-only tools use fast yet sophisticated scanning algorithms to scan the damaged area.
