Nhibernate setFirstResult

尝试使用setFirstResult时遇到Nhibernate版本3.3.3的问题。

IQuery q = session.CreateQuery("Select a from SelectionAssignment a ") 
                .SetFirstResult(1)
                .SetMaxResults(10);

var assignments = q.List<SelectionAssignment>();

上面吐出了这样的SQL:

SELECT TOP (10) asId30_
, asHostId30_
, asDescript3_30_
, asIsChase30_
, asPosition30_
, asGoalTime30_
, asRoute30_
, asActiveta8_30_
, asPassAssi9_30_
, asSummary10_30_
, asOverrid11_30_
, asDeliver12_30_
, asDirectLoad30_
, asAllowDe14_30_
, asVehicle15_30_
, asCustomerId30_
, asTotalWe17_30_
, asTotalItems30_

(
select selectiona0_.Id as Id30_
, selectiona0_.HostId as HostId30_
, selectiona0_.Description as Descript3_30_
, selectiona0_.IsChase as IsChase30_
, selectiona0_.Position as Position30_

, selectiona0_.SummaryPromptType as Summary10_30_

, selectiona0_.DeliveryLocationId as Deliver12_30_
, selectiona0_.DirectLoad as DirectLoad30_
, selectiona0_.AllowDeliverLocationOverride as AllowDe14_30_
, selectiona0_.VehicleLicense as Vehicle15_30_
, selectiona0_.CustomerId as CustomerId30_
, selectiona0_.TotalWeight as TotalWe17_30_
, selectiona0_.TotalItems as TotalItems30_
, selectiona0_.SingleSKU as SingleSKU30_
, selectiona0_.SingleBatch as SingleB20_30_
, selectiona0_.CreatedDate as Created21_30_
, selectiona0_.StartDate as StartDate30_
, selectiona0_.EndDate as EndDate30_
, selectiona0_.Priority as Priority30_
, selectiona0_.IsDeleted as IsDeleted30_
, selectiona0_.DeletedDate as Deleted26_30_
, selectiona0_.DeletedUser as Deleted27_30_
, ROW_NUMBER() OVER(ORDER BY CURRENT_TIMESTAMP) as __hibernate_sort_row 
from SelectionAssignment selectiona0_ where ( selectiona0_.IsDeleted=0)
) as query
 WHERE query.__hibernate_sort_row > 0 
 ORDER BY query.__hibernate_sort_row

然而,如果我将参数设置为.SetFirstResult(0),它可以正常工作。

谁能告诉我为什么?或者我如何解决这个问题?

编辑:道歉,我收到一条错误消息“无效列名'asId30''asHostId30'等。列名是Id,HostId等。

答案 0 :(得分:0)

我发现了这个问题。它似乎是列名“SelectionAssignment”引起了一个问题,因为NHibernate在生成的SQL上使用它自己的别名,它占用10个字符并添加一个数字。但是,我的列名中的第10个和第11个字符是“AS”。当它试图将自己的AS放在那里时,这似乎会导致与查询冲突。

一旦我将列名更改为不同的“PickingAssignment”,问题就解决了。

我希望我已经足够清楚地解释了它可以帮助其他人解决同样的问题。感谢jbl试图提供帮助。
