Sql server TSQL：将行转换为列

我们正在跟踪时间，需要报告给定班次花费的时间。表如下所示，服务订单重复，但阶段不同

serviceorderid stageid  recid       datetimeexecuted

我需要旋转它，以便每个工单有一行，以staged=Traveling开头。像这样：

serviceorderid   travel      started     completed   susp
WO-439660        5639344479  5639344574  5639345177  
WO-439660        5639345178                          5639349633
WO-439660        5639349917  5639349918              5639349920
WO-439660        5639349921  5639349923  5639349925

等等

这必须写在一个视图中

换班总是从stageId=旅行开始，如果我可以将所有东西从一个旅行分组到另一个旅行，那么我应该能够旋转。我不能按日期分组，因为轮班可以跨天。在这里与TSQL抗争，非常感谢您的帮助。

类似的方法应该可以：

;WITH CTE AS (
   SELECT serviceorderid, stageid, recid, datetimeexecuted,
          COUNT(IIF(stageid='Travelling', 1, NULL)) 
          OVER 
          (PARTITION BY serviceorderid 
           ORDER BY datetimeexecuted, 
                    IIF(stageid = 'Started', 3,
                        IIF(stageid = 'Travelling', 2, 1))) AS grp
   FROM mytable
)
SELECT serviceorderid,
       MAX(CASE WHEN stageid='Travelling' THEN datetimeexecuted END) AS travel,
       MAX(CASE WHEN stageid='Started' THEN datetimeexecuted END) AS started,
       MAX(CASE WHEN stageid='Complete' THEN datetimeexecuted END) AS completed,
       MAX(CASE WHEN stageid='Suspended' THEN datetimeexecuted END) AS susp
FROM CTE
GROUP BY serviceorderid, grp

像这样的方法应该会奏效：

;WITH CTE AS (
   SELECT serviceorderid, stageid, recid, datetimeexecuted,
          COUNT(IIF(stageid='Travelling', 1, NULL)) 
          OVER 
          (PARTITION BY serviceorderid 
           ORDER BY datetimeexecuted, 
                    IIF(stageid = 'Started', 3,
                        IIF(stageid = 'Travelling', 2, 1))) AS grp
   FROM mytable
)
SELECT serviceorderid,
       MAX(CASE WHEN stageid='Travelling' THEN datetimeexecuted END) AS travel,
       MAX(CASE WHEN stageid='Started' THEN datetimeexecuted END) AS started,
       MAX(CASE WHEN stageid='Complete' THEN datetimeexecuted END) AS completed,
       MAX(CASE WHEN stageid='Suspended' THEN datetimeexecuted END) AS susp
FROM CTE
GROUP BY serviceorderid, grp
