運行此Linq查詢時,我得到一個「NotSupportedException」。 「不支持指定的方法。」什麼方法?即使「Count()」被註釋掉了,錯誤也是一樣的。空內部例外。NotSupportedException與linq查詢和groupBy
堆棧跟蹤:
在Hydra.WPF.ViewModels.AddressListViewModel._primaryMemberListWorker_DoWork(對象 發件人,DoWorkEventArgs e)如 M:\項目\水潤\ WPF \的ViewModels \ AddressList中\ AddressListViewModel.cs:線 1377在 System.ComponentModel.BackgroundWorker.WorkerThreadStart(對象 參數)
SQL查詢:
Select * From _Members
Inner Join AddressDetailsCCN a on a.MemberId=_Members.MemberID
Inner Join
(
Select Address+Address2 as CombinedAddress
From AddressDetailsCCN Where ListId=84
group by Address+Address2
Having COUNT(*)>1
) B on B.CombinedAddress=A.Address+A.Address2
Where CombinedAddress is not null AND CombinedAddress!='' AND a.ListId=84
Order by ClientID, CombinedAddress
的Linq:
var grouped =
(from mem in session.Query<Member>()
join detail in session.Query<Detail>() on mem.Id equals detail.Member.Id
join d2 in (from d3 in session.Query<Detail>()
where d3.AddressList.Id == criteria.AddressList.Id
group d3 by d3.Address + d3.Address2 into x
where x.Count() > 1
select x) on detail.Address+detail.Address2 equals d2.Key
where detail.AddressList.Id==criteria.AddressList.Id
select mem);
哪條線是1377? – walther
Hibernate的linq實現對基本操作符有問題。我想知道我們什麼時候才能最終得到體面的實現...... –
1377只是調用存儲此方法的存儲庫方法。 – Seraph812
