How to grant read-only access to the data in an application

Hello All,

I will soon be decommissioning an application but this application will still need to be accessible by the users for historic purposes. I want the users to be able to view data only and I am thinking about my options on making this possible since I don't see any permissions setting in the application that will help me out on this.

The application is AD integrated and it points to a SQL database. It seems that the application have created SQL logins for the application users.

I was wondering if it would be possible to set the users to read-only by just assigning datareader role to their SQL logins.

Have someone come across to a similar situation?

Any help will be greatly appreciated.

Thanks!

If it's contained with one database, you can set that db to read-only.

But, yes, you should also be able to limit users to read-only by removing their existing permissions and just giving them datareader permissions.

Used to do this all the time with a reporting application and YES, setting the SQL users to "datareader" will allow them only that option as long as that is the only checkbox checked (public would also be checked).

Permissions can be granted outside of a "check" on a GUI/screen.  Indeed, being a DBA, I *never* assign permissions using a GUI.  For standard roles and some permissions, the check mark will show up from the command.  But some command permissions don't have corresponding check marks, but they still give permissions.

In short, don't rely on "check marks" to determine all permissions that are in effect.

are you sure the application doesn't use any stored procedures?

After attempting setting the database to Read-Only mode I could not even log into the application, later I found that the application need read and write permissions on an activity log table. I contacted the application's support and they stated that the only way to accomplish ReadOnly permissions was by setting the permissions in the application level which I ended up on doing so, the only drawback is that the permissions settings in the application are not that explicit and you have to guess per say what are the permission you actually need.
