Hi,
 I have resolved my post " http://www.ideablade.com/forum/forum_posts.asp?TID=820 - using sub query with PassthruEsqlQuery ".
 
But there is another problem. Please consider the following code
 

string str = "some passthrusql";

var query = new PassthruEsqlQuery(typeof(Subaccount), str);

if above query return record(one or more) then its working fine but if not it is throwing an exception, Below are the details.
 
IdeaBlade.EntityModel.v4.EntityServerException: Sequence contains no elements --->  System.InvalidOperationException: Sequence contains no elements.

Amit,
 
The good news is that this problem has been fixed in our DevForce EF Beta2 bits; the bad news is that there's no workaround for the problem in DEF Beta1.  
 
Thanks for reporting the problem.
