我在尝试使用 setFirstResult 时遇到了 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>();

上面吐出的 SQL 是这样的：

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_
, asSingleSKU30_
, asSingleB20_30_
, asCreated21_30_
, asStartDate30_
, asEndDate30_
, asPriority30_
, asIsDeleted30_
, asDeleted26_30_
, asDeleted27_30_ FROM 
(
select selectiona0_.Id as Id30_
, selectiona0_.HostId as HostId30_
, selectiona0_.Description as Descript3_30_
, selectiona0_.IsChase as IsChase30_
, selectiona0_.Position as Position30_
, selectiona0_.GoalTime as GoalTime30_
, selectiona0_.Route as Route30_
, selectiona0_.ActivetargetContainer as Activeta8_30_
, selectiona0_.PassAssignment as PassAssi9_30_
, selectiona0_.SummaryPromptType as Summary10_30_
, selectiona0_.OverridePrompt as Overrid11_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

而如果我将参数设置为 .SetFirstResult(0) 它工作正常。

谁能告诉我为什么？或者我该如何解决这个问题？

编辑：抱歉，我收到无效列名'asId30''asHostId30'等的错误消息。列名是Id，HostId等。

我发现了问题。似乎是列名“SelectionAssignment”导致了一个问题，因为 NHibernate 在生成的 SQL 上使用了它自己的别名，该别名需要 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发生冲突。

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

我希望我已经解释得足够清楚，并且它可以帮助其他人解决同样的问题。感谢 jbl 试图提供帮助。
