Hi Mariya, nnTo open SQL Server MDF database file, it is important to repair the file. It is possible that you are unable to open your file due to some corruption. To access your database tables, you can try many manual procedures to open corrupt MDF file. For example, DBCC CHECKDB inbuilt utility, Rebuild Wizard, etc.
I don't know how to use these inbuilt utilities. Can you please explain the working of these utilities?
I'll tell you how to work with DBCC CHECKDB inbuilt utility. Follow below steps: nn1. Run DBCC CHECKDB command on the database i. e. corrupted. nDBCC CHECKDB (Name of corrupt database)nn2. Check the index id. If id is greater than 1, then drop and recreate it. If It is 0 or 1, then run DBCC CHECKDB command with some repair options like repair_fast, repair_rebuild, repair_allow_data_loss. nFollow below command: nDBCC CHECK (name of corrupt database, repair_fast)nDBCC CHECK (name of corrupt database, repair_rebuild)nDBCC CHECK (name of corrupt database, repair_allow_data_loss)nn3. Run DBCC CHECKDB again to check zero corruption and then a new message will receive as shown: n"DBCC CHECKDB found 0 allocation errors and 0 consistency errors in ‘name of your corrupt database"
I tried this solution but unable to open corrupt MDF file. Can you share another method too?
Ok. First of all, go to this location for Rebuild Wizard to repair the database: n\Program Files\Microsoft SQL Server\80\Tools\BINN directorynnFollow these steps: n1. Double-click on Rebuildm. exe. Choose the database file and also verify other information in Collation Settings and then, click on Rebuild option. n2. After the confirmation message, click on Yes button. n3. Now, you can easily restore the master database. n4. Start SQL Server with SINGLE USER mode . In command prompt, type this command: nsqlservr. exe, c -m from the \Program Files\Microsoft SQL Server\MSSQL\BINN\. n5. Store the master database from backup by using Query Analyzer or SQL Enterprise Manager. n6. After restoring, you need to exit SINGLE USER mode and then, restart SQL Server in NORMAL OPERATION mode.
I am not getting the desired results. I have a big MDF database file with very important data. I am scared of losing it. Please suggest any safe and secure method.
To view data in MDF file, you can go for an automated solution. a third-party tool MDF Viewer Tool can easily repair and shows the preview of all the data items from the corrupted MDF file. Try this solution to access your database.
