Question

我有一个名为“Log”的下表。

LogID Description  Operator   LogType LogTimeStamp         JobNo  DNo
===== ============ ========   ======= ============         =====  ===
1     Job booked.. John       101     2016-01-01 00:00:00  44111  Null
2     Job booked.. Smith      101     2016-01-01 00:01:00  44112  Null
3     Offered...   (System)   104     2016-01-01 00:01:30  44111  230
4     Rejected...  (System)   105     2016-01-01 00:01:30  44111  230
5     Offered...   (System)   104     2016-01-01 00:02:00  44112  135
6     Offered...   (System)   104     2016-01-01 00:02:36  44111  042
7     Accepted...  (System)   107     2016-01-01 00:02:42  44111  042
8     Accepted...  (System)   107     2016-01-01 00:02:43  44112  135
9     Arrived...   (System)   108     2016-01-01 00:05:30  44111  042
10    POB...       (System)   109     2016-01-01 00:07:00  44111  042
11    Arrived...   (System)   108     2016-01-01 00:08:30  44112  135
12    POB...       (System)   109     2016-01-01 00:08:36  44112  135
13    Complted..   (System)   112     2016-01-01 00:15:00  44111  042
14    Forced Coml. John       1120    2016-01-01 00:20:30  44112  135

注意：上面（在描述栏中）只是一个提取。完整值如下所示：

Job Booked (Pickup time 01:18 Wed 01/06/2016) from Caller 07599999999 calling 300
Job on queue N Gwich accepted by driver on queue WTnC
Arrived at Stop 1
POB at Stop 1
ATTENTION Event Dismissed, 44111 has Rejected a Job
Arrived at Stop 2
POB at Stop 2
Job completed (Approx Paid Mileage = 1.6, Dead Mileage = 1.4)
Job needs to be verified - Account requires all jobs be verified

问题：是否可以按以下格式（列中）提取数据：

JobNo  DNo  Booked_By  Booked_On Offered_At Accepted_At Arrived_At POB_At   
Completed_At

到目前为止我所做的是以下内容：

SELECT 
   [LogID]
  ,[LogTimeStamp]
  ,[LogType]
  ,[JobNo]
  ,[Operator]
  ,[Description]
  ,[TelephoneNumber]
   ,CASE WHEN l.LogType = 101 THEN l.LogTimeStamp END AS JobBookedOn
   ,CASE WHEN l.LogType = 101 THEN l.Operator END AS JobBookedBy
   ,CASE WHEN l.LogType = 107 THEN l.LogTimeStamp END AS JobAcceptedOn
   ,CASE WHEN l.LogType = 108 AND l.Description LIKE '%Arrived%Stop 1%' 
THEN l.LogTimeStamp END AS ArrivedAtStop1
   ,CASE WHEN l.LogType = 110 AND l.Description LIKE '%POB%Stop 1%' THEN 
l.LogTimeStamp END AS POBAtStop1
   ,CASE WHEN l.LogType = 112 THEN l.LogTimeStamp END AS JobCompletedOn
   ,CASE WHEN l.LogType =   7 THEN l.LogTimeStamp END AS 
JobForcedCompletedOn
   ,CASE WHEN l.LogType = 301 THEN l.LogTimeStamp END AS CallReceivedOn
FROM [DB_A].[dbo].[Log] AS l
WHERE 
  (LogType = 101 OR
   LogType = 107 OR
   LogType = 108 OR
   LogType = 110 OR
   LogType = 112 OR
   LogType = 7 OR
   LogType = 301)
   AND
   l.JobNo = 4753784
ORDER BY LogTimeStamp DESC

到目前为止我所取得的成绩如下图所示。请注意，这是截断的图像。

只能使用值获取一行，或者在没有值的情况下使用null。

我试过调查PIVOT，但无法掌握如何做到这一点。另一种选择看起来像CURSOR ......任何建议???

提前致谢。

额外信息：下面显示了创建命令的创建命令：

CREATE TABLE [dbo].[Log](
    [LogID] [int] IDENTITY(1,1) NOT NULL,
    [LogTimeStamp] [datetime] NOT NULL,
    [LogType] [int] NULL,
    [JobNo] [int] NULL,
    [DrvName] [varchar](50) NULL,
    [Operator] [varchar](16) NULL,
    [Description] [varchar](255) NOT NULL,
    [TelephoneNo] [varchar](30) NULL
) ON [PRIMARY]

要播放的一些数据（CSV文件）：

Answer 1

这就是你要做的事情：

请注意，由于未提供此字段，我的答案缺失DNo。但是，假设DNo与JobNo的关系为1：1，那么您只需将其添加到SELECT和GROUP BY即可。

如果是这样，那么你几乎就在那里：

 SELECT [JobNo],
           MAX(CASE
                   WHEN l.LogType = 101
