database attached is read only

Question

I used the following the script to attach a database. But the database created is read only.
What modifications should I make in the script to make it read-write. Pl

Answer 1

You need to change permission for your database folder: properties -> security tab -> edit... -> add... -> username "NT Service\MSSQL$SQLEXPRESS" or "NT Service\MSSQLSERVER". Close the windows, open Advanced..., double click the user and set as follows: Type: Allow Applies to: This folder, subfolder and files Basic permissions: all Make sure the owner is set too.

Answer 2

First make sure that the folder in which your .mdf file resides is not read only. If it is, un-check that option and make sure it reflects to folders and files within that folder.

Once that is done, Open Management Studio, in the Object Explorer right click on the Database which is read only and select Properties. In the Options Menu, check that the Read-Only property is false.

Answer 3

You need to go to the new folder properties > security tab, and give permissions to the SQL user that has rights on the DATA folder from the SQL server installation folder.

Answer 4

If you have tried all of this and still no luck, try the detach/attach again.

Answer 5

Answer from Varun Rathore is OK but you must consider that starting from Windows Server 2008 R2 and higher the SQLServer service will run under a local virtual account and not anymore under the old well known "NETWORK SERVICE". Due to this, to switch a newly attached DB to "not read only mode", you must setup permissions on the ldf and mdf files for local machine user line "NT SERVICE\MSSQLSERVER" where MSSQLSERVER would be the service name in a pretty standard installation.

Answer 6

Open database properties --> options and set Database read-only to False.

• Make sure you logged into the SQL Management Studio using Windows Authentication.
• Make sure your user has write access to the directory of the mdf and log files.
