The simplest way to do this is with a PassthruRdbQuery.  There is an Intermediate Tutorial named "Pass-Through Queries".
 
There is a more complicated way to do this which requires writing some code which executes server-side.  There is an Advanced Tutorial named "Remote Service Methods".

This question belongs in the "DevForce Classic Edition Topics" forum, not the Silverlight forum.

But to answer your question, yes, you can.

In your business object you can add this:

VB:

    Private _newWhereClause As String = "WHERE CLAUSE HERE"

    Public Overrides ReadOnly Property SqlWhereClause() As String
        Get
            Return _newWhereClause
        End Get
    End Property

C#:

private string newWhereClause = "WHERE CLAUSE HERE";

public override string SqlWhereClause()
{
         get
         {
              return newWhereClause; 
         }
}

For DevForce Silverlight, you would not use a SqlWhere clause in a command that you would send to the database.  You would use Linq and send the query to a DevForce EntityManager.
