What does the connect permission allow to happen?

Posted By:      Posted Date: October 16, 2010    Points: 0   Category :Sql Server

I know to login you need connect to database Grant & Login Enabled.

What can you do when you have just connect to database Grant & Login Disabled

Can you connect through say PHP and select update tables if you have permission that is?

I ask because I want allow a user to modify there account data which is stored in a table through a website.

However you wouldn't want the user to be able to login to a database and change everybody's account information in the table that they should only be able to edit their row.

could somebody give me example how I can connect to database only once if I use many models in contr


I use in my ASP.NET MVC application repository pattern and I use in controller for example 3 models:

   namespace MvcApplication1.Controllers  
        public class HomepageController : Controller  
            private IWebsitesRepository _repository_websites = new WebsitesRepository();  
            private IFirmRepository _repository_firm = new FirmRepository();  
            private IPhotosRepository _repository_photos = new PhotosRepository();

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help.

ASP.Net connect to Oracle.


 We have an application which uses  'System.Data.OracleClient'. On the box it was developed we can change the TNSNAMES.ORA entries to connect to different oracle databases. Moving the code to a  Microsoft Server 2008 box it would appear that the application ignores the TNSNAMES.ORA file. It has cached the first Oracle connection and will now work without any TNSNAMES.ORA file. Where is it getting the connection? We have set tns_admin to point at the TNSNAMES.ORA file. We can tnsping the connection OK.

Facebook Connect


Does anybody have links to relevant articles on how Facebook Connect integrates with the Membership provider?

I'd like to make a .net site where you can login through the membership provider, or the Facebook Connect system.  But the big question is, how does your asp.net application know when the Facebook authentication has been successful.  Without manually entering a username and password, is there a function to authenticate users and draw the profile info from Facebook's data?

It seems like a good system, but the documentation is sparse.

Error "user does not have permission to perform this operation" with User Instance = True.


I setup SQL Server 2005 / SQL Express. All works fine in SQL Server 2005.

I am connecting to a SQL Database from VS 2005,  Tools/Connect to Database. I set the Data Source to "Microsoft SQL Server Database File (SqlClient)" (meaning SQL Server Express) and User Instance = True, and Integrated Security = True.

The above is working successfully on all machines except my Laptop. On my Laptop, I am getting this error "user does not have permission to perform this operation". On my Laptop, if I change User Instance = False, it works fine. Also, If I connect to SQL Server 2005 it works fine only if User Instance = False.

I tried all kind of security changes, nothing worked. For example, I setup Everyone as Full Control for the Folder and the MDF File of SQL Server. I gave my user ID as sysadmin role in SQL Server Express. Also, I enabled creating User Instance form SQL Server Express, Nothing is working.

Appreciate your help.


Basic ODBC Connection to connect to Crystal ???


I have visual studio 2008 professional with the inbuilt crystal reports version 10 I think.  I create everything from my laptop and IIS runs from my laptop as well.

I have created the most basic report to try and figure out a problem I have, anyways the report contains one database field that is it .... which I connect to by ODBC.  I then create a web form add the crystal report viewer to the report and the crystal report source run the web page and it loads the data from the field as I would expect to the crystal report viewer !!

I have several ODBC connections setup on my machine one using integrated security the other using SQL authentication both are system DSNs.  Now when I publish my application and access it from IIS and not the localhost I can access everything from my application ok except when I go to form that has the crystal reports I get this error (ODBC used here is the 'sa' account)

Logon failed. Details: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified Error in File

If I use the other ODBC that uses Windows authentication I get this error message

Logon failed. Details: 42000:[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database  requested by the login. T

Enter your credentials to connect to the web service


When trying to publish an InfoPath 2007 form template (as a Content Type), I am getting the following message with a UserName/Password dialog box:
Enter your credentials to connect to the following web service: http://MySitePath/_vti_bin/Webs.asmx

When I enter my credentials, the above dialog box appears again. I have carefully entered my credential. Another thing I noticed that despite this error I see the form got created at the destination library. The only thing is that the Content Type did not get created and hence is not available in the "Site Content Type Gallery".

We are using Sharepoint 2007 enterprise edition. And I have recently published the InfoPath form templates several time as Content type without any issue.


Please help. Thanks........
