我有這樣的SQL查詢 SELECT SUM(DATEDIFF(MINUTE, InTime , OutTime)) /60
FROM Attendance
WHERE InTime BETWEEN '01-01-2016' AND '01-31-2016'
AND Employee=63
var AttendofEmp = (from ab in db.Attendances
我想將此sql轉換爲Linq查詢，但我沒有成功。你能幫忙嗎？ SELECT G.Id,G.UserGroupName, G.Status, G.IsDeleted ,(SELECT COUNT(*) FROM UserGroupMapping U WHERE U.UserGroupId=G.Id) [UserCount]
,(SELECT COUNT(*) FROM UserGroupRoleM
任何人都可以幫助我嗎？我不能給下面的表達式轉換在SQL等效Lambda表達式， ON nextT.TaskID = a.NextTaskID AND a.TaskID <> nextT.TaskID
SQL轉換 SELECT a.*
FROM dbo.Action AS a INNER JOIN dbo.Task AS t
ON t .TaskID = a.TaskID
INNER
誰能幫我寫等價的SQL選擇組值的LINQ C＃ select
COUNT(ot.UserId) as orderCount, SUM(ot.TotalAmount) as TotalAmount,
MAX(u.UserName) as UserName, MAX(c.name) as ClientName
from OrderTemplate ot
join User u
on u.us
我是非常新的LINQ，所以我不明白什麼確切的Linq查詢是這個SQLQuery。 請給出確切的Linq類似於此SQL查詢的查詢。 Select * From tblProduct
Where ProductId In
(Select ProductId from tblViewer Where ViewerId = 123)
這是我的SQL命令： select
b.Brand,
count(b.Brand) as BrandCount,
SUM(a.Qty) as DeviceCount
from (
select * from DeviceList
) as a
join DeviceMaster as b
on a.DeviceMasterId = b.Id
我有這樣的SQL查詢by子句 select Distinct(EmpNTLogin),Employee from Attendance
where CreateDate>='2016-01-01'
order by EmpNTLogin
使用順序，給了我正確的結果，即由A排序到Z的員工的所有名字，當我轉換Linq中相同的查詢，我得到正確的結果，但按子句排序不起作用。 這裏是我的Linque
