問題SQL轉換到LINQ到實體聲明

我們是在把SQL /存儲過程LINQ到實體報表的過程。問題SQL轉換到LINQ到實體聲明

目前我將這個SQL：

declare @startDate DateTime 
set @startDate = DATEADD(DD, -30, GETDATE()) 

select h.* 
from History h (nolock) 
    inner join Quote q (nolock) on h.QuoteID = q.QuoteID 
    inner join Agency (nolock) a on q.AgencyID = a.AgencyID 
    inner join DC_PLT_EntityRoles er (nolock) on a.AgencyID = er.EntityID 
    inner join DC_PLT_Roles (nolock) r on er.RoleID = r.RoleID 
where 
    q.Status = 'Inforce' 
    and q.LOB = 'Vacant' 
    and q.EffectiveDate > @startDate 
    and h.Deleted is null 
    and h.DeprecatedBy is null 
    and h.TransactionStatus = 'Committed' 
    and r.Name = 'Wholesaler'

這是LINQ到實體，我寫了：

var startDate = DateTime.Today.AddDays(-30);  
var results = (from h in Histories 
     .Include("Quote") 
     .Include("Quote.Agency") 
     .Include("Quote.Agency.DC_PLT_Roles") 
    where h.Quote.Status == "Inforce" && 
       h.Quote.LOB == "Vacant" &&   
       h.Quote.EffectiveDate > startDate && 
       h.Deleted == null && 
       h.DeprecatedBy == null && 
       h.TransactionStatus == "Committed" && 
       h.Quote.Agency.DC_PLT_Roles.All(r => r.Name == "Wholesaler") 
    select h).ToList();

的問題是SQL返回77行，我的LINQ返回無。

任何人有我如何才能正確地轉換任何想法？或者我錯過了什麼。

感謝您的幫助。
