        Order By TourDateRange.ID Desc

        Select '' as Detail,@sTourID as TourID,'' as TourDateRangeID,StartDate,EndDate,AdultPrice,ChildPrice,ID as TourDatesID From TourDates where TourID = @sTourID AND TourDateRangeID is Null

帮我解决这个问题我想加入一个单一的查询...意味着要把1个数据表放在后面

Answer 1

据我所知，您的查询很清楚，您需要参加结果导览，其中包括＆＃34; TourDateRange＆＃34;加上那些没有的。

我希望这会给你所需的结果：

Select 
    ISNULL(TourDateRange.Detail, '') AS Detail,                
    TourDates.TourID,
    ISNULL(TourDates.TourDateRangeID, '') AS TourDateRangeID,
    MIN(TourDates.StartDate) AS MinStartDate,
    MAX(TourDates.EndDate) AS MaxEndDate,
    TourDates.AdultPrice,
    TourDates.ChildPrice,
    MAX(TourDates.ID) as MaxTourDatesID
From 
    TourDates 
    LEFT OUTER JOIN TourDateRange
        ON TourDates.TourDateRangeID = TourDateRange.ID
Where 
    TourDates.TourID = @sTourID
GROUP BY
    ISNULL(TourDateRange.Detail, '') ,                
    TourDates.TourID,
    ISNULL(TourDates.TourDateRangeID, '') ,
    TourDates.AdultPrice,
    TourDates.ChildPrice,
Order by
    TourDateRangeID

Sql查询将它们组合成1 ..需要帮助
