Question

测试数据表 - user_traveldetails

ID  FromDate ToDate   UserId

1  1/1/2014 1/10/2014  44

2  2/1/2014 3/10/2014  44

3  1/1/2015 2/10/2015  44

预期产出：

FromDate1  ToDate1    FromDate2 ToDate2    FromDate3  ToDate3    UserId
1/1/2014   1/10/2014  2/1/2014  3/10/2014  1/1/2015   2/10/2015  44

我需要从日期开始并提交到单行。

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX);   
    SET @cols = STUFF((SELECT top 12 ',' + quotename(fromdate) FROM      User_TravelDetails group by(fromdate) order by MAX(fromdate) desc FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')     
        set @query = 'Select *  from (select id as fromid, email as fromemail, ' + @cols + '     from   (   SELECT *    FROM
       (select top 10000 A.ID,Email,userid,FromDate,visit from UserMaster A
        inner join User_TravelDetails B     
        on A.ID= B.USerid order by B.FromDate
        ) as s  PIVOT 
        ( MIN(FromDate) FOR [FromDate] IN (' + @cols + ')
        )AS pvt
        ) as X)     
     P join 

    (Select id as toid, email as toemail,' + @cols +
     'from(SELECT * FROM (select top 10000
     A.ID,Email,userid,toDate,visit from UserMaster A
     inner join
     User_TravelDetails B   on A.ID= B.USerid order by B.FromDate   ) as s
     PIVOT(MIN(toDate) FOR [toDate] IN (' + @cols + ')  )AS pvt2
     ) as Y ) Q on P.fromemail=Q.toemail'
     print @query   EXEC
     SP_EXECUTESQL @query

请帮助查询。感谢
