将 SQL 语句转换为 LINQ VS2010
本文关键字:LINQ VS2010 转换 SQL 语句 | 更新日期: 2023-09-27 18:34:37
我将不胜感激将以下sql语句转换为linq的帮助:
select *
from (
select
*,
rn = row_number() over (partition by ClientId order by VisitId)
from
Visit
) activityWithRn
inner join vw_MasterView on vw_MasterView.VisitId = activityWithRn.VisitId
where activityWithRn.rn =3
当我使用Linqer(一个很棒的程序(时,我收到以下错误:
SQL cannot be converted to LINQ: Field [rn = row_number() over (partition by ClientId order by VisitId)] not found in the current Data Context.
提前谢谢。
我认为 LINQ 中没有任何相应的功能用于row_number() over
,除了使用 Skip...Take
:
var q = (from v in Visit
join mv in vw_MasterView on v.VisitId equals mv.VisitId
orderby v.VisitId
select v).Skip(2).Take(1);
