EntityCommandExecutionException was unhandled see innerException for Details

E E Cummings534519-Jun-2013
Hi All,

I am trying to connect my C# application with SQL server compact edition using ADO.NET entity Model.

I think I have been successfully able to generate the model against the database schema.

However when I try to use the entity objects in code I get the

EntityCommandExecutionException` was unhandled error along with "An error occurred while executing the command definition. See the inner exception for details."

Here's the code

Database1Entities db = new Database1Entities();
var query = from item in db.People
                    select Name;
foreach (var item in query)
{
    MessageBox.Show("The name of the customer is " + item);
}


It says to check inner exception. When I did checked InnerException gave me the error

"InnerException {"A parameter is not allowed in this location. Ensure that the '@' sign is in a valid location or that parameters are valid at all in this SQL

statement."} System.Exception {System.Data.SqlServerCe.SqlCeException}"

Now I am entirely new to using entity framework for generating objects from database sachems. I would really appreciate some guidance in this regard.

Thanks in advance for any recommendations or solutions.
