1/ Are you been able to perform read / write operations from SQL Server Management studio? 2/ Please show your connection string. 3/ How did you deploy the application? Was there any read only media such as CD was involved in the process? 4/ Have you right click on the physical .mdf / .ldf files and have confirmed that the files themselves are not read only flag set? Please answer ALL the questions above.

Just mentioning "my problem is not solved" isn't quite helpful for us. Please give detailed description. Please provide the the few lines of code where the error is being shown. Please post the screen shot of the error messages displayed. Also post the complete stack trace of the error. It is only then that we know what exactly are you attempting to do. To tell you the truth, i don't even trust the error description unless I see the screen shot. You should also show / confirm that the solution provided so far have already been rectified.

Hi, Update the database permission. i.e. Mark database “yourDataBaseName” as read-write. We can simply do it using next T-SQL Commands, USE master GO ALTER DATABASE "YourDataBaseName" SET READ_WRITE WITH NO_WAIT GO Execute this query in a window. Then try it.

Nitin Sontakke · Answer

The error is very self explanatory.
