加入sql查詢

Question

你能幫助這兩個查詢嗎？

查詢之一：

declare @startdate datetime 
declare @enddate datetime 
set @datainicio='2014-03-01' 
set @datafim='2014-03-03' 
select right([Location Code],4) as Vehicle,MIN(CAST(CAST([date]AS DATE) AS DATETIME) + 
    CAST([entry time]AS TIME)) as DaeaMin,min([Veihicle Kms]) as KmsMin,MAX(CAST(CAST([date]AS DATE) AS DATETIME) + 
    CAST([entry time]AS TIME)) as DateMax,max([Veihicle Kms])as KmsMax 
where quantity>=0 and [Location code] like 'v%' and [item no_]='601.0001' and ([date] between @startdate and @enddate) 
group by [Location Code] 

查詢二：

SELECT Vehicles.Designation as Vehicle, 
SUM(Locations.DistanceFromLastLocation)/1000 as 
KMS,convert(varchar(10),LocationDate,120) as Date 
FROM Locations INNER JOIN Vehicles ON Locations.VehicleId = Vehicles.VehicleId 
GROUP BY Vehicles.Designation,LocationDate 

我想加入這兩個查詢的車輛和查詢兩個日期必須是從查詢一個datemin和datemax之間。

幫助，謝謝。

Answer 1

希望這有幫助，比其他答案有點容易理解。注意我已經包含了拼寫錯誤;）

declare @startdate datetime 
declare @enddate datetime 

set @datainicio='2014-03-01' 
set @datafim='2014-03-03' 

SELECT * 
FROM (
    select right([Location Code],4) as Vehicle,MIN(CAST(CAST([date]AS DATE) AS DATETIME) + 
    CAST([entry time]AS TIME)) as DaeaMin,min([Veihicle Kms]) as KmsMin,MAX(CAST(CAST([date]AS DATE) AS DATETIME) + 
    CAST([entry time]AS TIME)) as DateMax,max([Veihicle Kms])as KmsMax 
    FROM YOURTABLE 
    where quantity>=0 and [Location code] like 'v%' and [item no_]='601.0001' and ([date] between @startdate and @enddate) 
    group by [Location Code] 
) x 
INNER JOIN (
    SELECT Vehicles.Designation as Vehicle, 
    SUM(Locations.DistanceFromLastLocation)/1000 as 
    KMS,convert(varchar(10),LocationDate,120) as Date 
    FROM Locations INNER JOIN Vehicles ON Locations.VehicleId = Vehicles.VehicleId 
    GROUP BY Vehicles.Designation,LocationDate 
) y 
ON x.Vehicle = y.Vehicle 
AND y.DATE BETWEEN x.DaeaMin AND x.DateMax 

Answer 2

由於您在第一個查詢中沒有提到子句，因此我假定您要從「位置」表中獲取數據的第一個查詢爲。 以下回答可能有用。

;with temp as 
(
    SELECT Vehicles.Designation as Vehicle, 
      sum(Locations.DistanceFromLastLocation)/1000 as KMS, 
      convert(varchar(10),Locations.LocationDate,120) as Date 
    FROM Locations 
    INNER JOIN Vehicles 
    ON Locations.VehicleId = Vehicles.VehicleId 
    group by Vehicles.Designation,Locations.LocationDate 
) 

select right(Locations.[Location Code],4) as Vehicle, 
     MIN(CAST(CAST([Locations.date]AS DATE) AS DATETIME) + CAST([Locations.entry time]AS TIME)) 
     as DateaMin, 
     min([Locations.Veihicle Kms]) as KmsMin, 
     MAX(CAST(CAST([Locations.date]AS DATE) AS DATETIME) + CAST([Locations.entry time]AS TIME)) 
     as DateMax, 
     max([Locations.Veihicle Kms])as KmsMax 
FROM Locations 
Inner Join temp on 
temp.Vehicle = right([Locations.Location Code],4) 
where Locations.quantity>=0 
and [Locations.Location code] like 'v%' 
and [Locations.item no_]='601.0001' 
and ([Locations.date] between @startdate and @enddate) 
and temp.[Date] between 
MIN(CAST(CAST([Locations.date]AS DATE) AS DATETIME) + CAST([Locations.entry time]AS TIME)) 
and 
MAX(CAST(CAST([Locations.date]AS DATE) AS DATETIME) + CAST([Locations.entry time]AS TIME))
