Dynamic Linq .Select() - How to handle certain null values -


I am using System.Linq.Dynamic for a project, for which the user needs to choose that on runtime Which properties to choose?

So, I have such a query: 

  var query = db. Select ("New User ID, User Name, Group Max (Date specified) AS DateInserted");   
 The date-specified column is not empty, but there are no groups of all users. Therefore, when a user is returned without groups, I get the following error:  
  "value type 'datetime' fails because unlimited value is zero. The query should use a faucet type. "  
 Can I do anything in the query? I can not empty the column.  
 Thanks for any help.   
 
 
 Faucet type date time? In this way:  var query = db.Users.Select ("New UserId, Username, Date Time? (Specified as Group Date (Date specified))");
