I tried to create an external content type for a website and I got an error....here are the details of the steps I followed:

1. I created an team site in sharepoint server 2010.Nothing I added extra to the site.

2. Then I opened that site in sharepoint designer and created a new external data type.

this is an SQL server. I have a small database in my server, I added that as an external data type to this site.

3. I am able to add the database to my site.

4. Then I created an External List of type contact list as my database has article ID, author, data of creation etc.

5. This creation also sucessfull and when I clicked on create button , my external list appeared on the quick launch but it didn't displayed anything on the page it showed up the below error on the page.

Error while connecting External List to SharePoint Workspace

  

Hi,

I have an external list in SharePoint 2010 which I want to take offline using SharePoint WorkSpace. Whilst logged into SharePoint I click the "Sync to SharePoint WorkSpace" button on the ribbon, select the views I want to take offline and off it goes.....

....however it errors and wont take offline the list.

Local event log shows:

Could not open connection using 'data source=VM1;initial catalog=AdventureworksLT;integrated security=SSPI;persist security info=false;pooling=false' in App Domain 'BCSSync'. The full exception text is: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

My login has the correct permissions on the DB, the BDC service app etc and I can view/edit the list throught the browser.

I'm baffled and not sure what to try next

Error creating Read Item or Read List operation in Sharepoint Designer 2010

  
In terms of high-level requirements, I need to pull in lists from a couple of different web apps.  To do this, I’m using SPD 2010 to create an External Content Type for the list of interest.  I’m able to create a SOAP Service or WCF Service connection just fine.  However, when I try to create the external content type and create a Read Item Operation on one of the GetList or any other Get* (or other Update methods for that matter) methods, I get the following error:"The method that your operation is based on has parameters with complex types that do not have default parameterless constructor.  This kind of data source methods cannot be used in Business Data Catalog."I tried defining an operation on the “AddAttachment” method, and that worked just fine.  I also tried providing default values to the listName and viewName parameters when creating the SOAP Service connection, but still get the error.  Same issue with a WCF Service connection as well. Does anyone know if this is a 2010 issue, or am I approaching this requirement incorrectly?  What are other approaches for connecting to lists that reside in a different web app than yours? 

Best way to display data of a single column from a Sharepoint Custom List

  
I'm trying to create pages that will automatically populate with data pulled from a sharepoint list (like title, department, contact info, etc.).   I'm using publishing pages. What would be the easiest way to do this, and how would I specify which data to pull from the list? For example, the page would be set up like this: [Title:biology] [Department:biology] [Contact Info:biology]   and when the page loads, it would look like this: Biology Lab Biology Department 123-456-7890   I want it to just pull the data -- I don't want a list view or anything like that.  I need this page to look pretty, and I need the each column's data to show up in a very specific place. How could I make pages that would do that?
