在列中对行进行分组和合并

我有以下问题。我需要获得具有以下数据的新报告：

1-乘客在同一预订号码一起旅行的列（预订），因此新栏目应包含与主要乘客一起旅行并以逗号分隔的所有乘客。并且每位乘客应该有自己的记录，并再次添加新列（乘客一起旅行）同一预订中的其他乘客。例如：

2-同一预订中的乘客数量号码将存储在名为（乘客人数）的栏目中

3-如果航班是通过连接点（过境城市）我想把连接城市放在一个叫做（过境城市）的新列中，如果有一个以上的过境城市，那么两个城市应该分开提到用逗号。例如，乘客从A到D旅行，在B过境一小时，有时在C过境3小时，因此过境城市应包括B，C。并且出发城市应该是A和到达城市应该D.所以一行将包含这个信息/乘客。

3-购买日期和航班日期之间的差异将存储在一个名为（购买和航班日期之间的差异）的新列中

4-抵达日期是新的要求，其中应包括第二航班的出发日期，例如预订的乘客从A到B，然后B到C，第一次航班的出发时间是在2013年12月22日和第二次航班是在2013年12月23日，所以抵达将是最后一班航班起飞日期。

这是表结构：

CREATE TABLE table1(
[Pax ID] [int] NULL,
[Reservation] [int] NULL,
[Surname] [varchar](40) NULL,
[First Name] [varchar](40) NULL,
[Pax Type] [char](1) NULL,
[Flight Date] [smalldatetime] NULL,
[Flight Number] [varchar](10) NULL,
[Board] [varchar](3) NULL,
[Off] [varchar](3) NULL,
[Original Booking Date] [smalldatetime] NULL,
[Last Mod Date] [smalldatetime] NULL
) 

INSERT INTO table1([Pax ID],[Reservation],[Surname],[First Name],[Flight Date],[Flight Number],[Board],[Off],[Original Booking Date],[Last Mod Date])
SELECT '1558611','899842','SULIMAN','ALI','2/1/2013','FO151','RIY','SAH','1/1/2013','1/1/2013'   UNION ALL

这是我已经达到的目标

SELECT [Pax ID],[Reservation],[Surname],
STUFF((SELECT ',' + [Surname] FROM [TABLE1] WHERE [Reservation] = t.[Reservation] AND  [Surname] <> t.[Surname] FOR XML PATH('')),1,1,'') AS [pax in same res#],
COUNT(1) OVER (PARTITION BY [Reservation]) AS [# of pax],
DATEDIFF(dd,[Purchase date],[Flight date]) AS [Diff flight date purchase date],
STUFF((SELECT DISTINCT ',' + t1.[Off] 
FROM [TABLE1] t1 
JOIN [TABLE1] t2 
ON t1.[Pax ID] = t2.[Pax ID]
AND t1.[Reservation] = t2.[Reservation]
AND t1.[Off] = t2.[Board]
WHERE t1.[Pax ID] = t.[Pax ID]
AND t1.[Reservation] = t.[Reservation]
FOR XML PATH('')
),1,1,'') AS TransitCity,
[Flight date],
STUFF((SELECT ',' + [Flight Number]
FROM [TABLE1] 
WHERE [Pax ID] = t.[Pax ID]
AND [Reservation] = t.[Reservation]
FOR XML PATH('')
),1,1,'') AS FLightNo,
(SELECT TOP 1 [Board]
FROM [TABLE1] 
WHERE [Pax ID] = t.[Pax ID]
AND [Reservation] = t.[Reservation]
ORDER BY [Flight date] ASC) AS DepartCity,
(SELECT TOP 1 [Off]
FROM [TABLE1] 
WHERE [Pax ID] = t.[Pax ID]
AND [Reservation] = t.[Reservation]
ORDER BY [Flight date] DESC) AS ArrivalCity,
[Last Mod Date],
[Purchase Date]
FROM (SELECT [Pax ID],[Reservation],[Surname],MAX([Flight Date]) AS [Flight date],MAX  ([Original Booking Date]) AS [Purchase Date],MAX([Last Mod Date] ) AS [Last Mod Date]
FROM [TABLE1]

GROUP BY [Pax ID],[Reservation],[Surname]) t

需要输出
