As I'm sure you're already aware one of the biggest weaknesses of the data view web part is that it exposes connection strings for SQL Server connections.

Instead of using a web service to pass my data I was hoping to take advantage of integrated security (use Windows user authentication) to connect to my SQL server - is this possible?

I've tried using the option 'use custom connection string' and setting my connection string to the following:

Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

This unfortunately returns the error:

Server Error: An error occured while retrieving the list of databases from x: The server for the data source returned a non-specific error when trying to execute your query. Check the format and content of your query and try again. If the problem persists, contact the server administrator.

Do I have to resort to a web service or is there a better way to do this?

First, Try to use the following connection string (Imp: note the Provider should be written twice as below).

Data Source=MyDB_Server;Database=MyDB;Integrated Security=SSPI;Initial Catalog=MyDB;Provider=SQLOLEDB;Provider=SQLOLEDB

If this does not work, You can use SSO. See here : http://blogs.msdn.com/b/sharepointdesigner/archive/2007/08/27/an-introduction-to-single-sign-on-sso-with-data-views.aspx

In MOSS (Sharepoint 2007) you can also use BDC to surface data from SQL Server. Check this out : http://msdn.microsoft.com/en-us/library/bb736296(v=office.12).aspx

If you want to surface the data from SQL Server in SharePoint 2010,the best way to do it is via BCS. Check this : http://msdn.microsoft.com/en-us/magazine/ee819133.aspx. Also If you want to keep the credentials confidential, you can use Secure store service as well.

    @Michael, Can you let us know which of the above option worked for you Commented Mar 2, 2012 at 7:50

In SQL, add a User Mapping to the SharePoint Content database in the properties of the login you are using for your Data View.


I am using sp2010 but it might work for 2007


you can set the asp datasource in this manner

    static void Main(string[] args)
        using (SPSite site = new SPSite("http://sps2010"))  // e.g. http://server/sites/asite

    using (SPWeb web = site.OpenWeb())
        SPFile file = web.GetFile({page contianig webpart});   // e.g. /sites/asite/default.aspx
        SPLimitedWebPartManager lwpm = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
        SPLimitedWebPartCollection webParts = lwpm.WebParts;
        DataFormWebPart wp3 = (DataFormWebPart)webParts["g_5c1e1e6a_294b_4b4f_8e19_6c061542a952"];
        wp3.DataSourcesString = {DataSourceString}
       // g_5c1e1e6a_294b_4b4f_8e19_6c061542a952
