【问题描述】：
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 Invalid column name 'asId30' 'asHostId30' 等错误消息。列名是 Id、HostId 等。
【问题讨论】：
-
我想这可能是一个愚蠢的评论，但你能指出问题出在哪里吗？
-
抱歉编辑解释
-
可能是方言问题，但是，首先要添加的是您的 select 语句中的 ORDER BY。没有它，First 和 Max 毫无意义。
-
我按顺序添加了，没有任何区别。我用 2008 年和 2012 年的方言都试过了。它们都产生了错误的查询。
-
如果使用以下命令切换查询模型会发生什么：var assignments = session.Query
().OrderBy(a => a.Id).Skip(1).Take(10)。 ToList();
