Question

由于报告的类型不同，我为这个项目创建了几个不同的select语句，但现在我有一个有趣的场景，但我认为它会更常见，或者我只是没有使用正确的术语

我最近的障碍是我试图将两张桌子加在一起，但不是在同一行，而是在同一列......

所以我有这个查询根据扫描时间分区挑选票号...

<div>IT WORKS</div>

这是它的输出 -

WITH ticket AS
(
SELECT ticket_trail.PickT_Num
,ticket_trail.ticket_status
,ticket_trail.ID
,cast(ticket_trail.Time_stamp as DateTime)as 'time_stamped',
ROW_NUMBER() OVER(PARTITION BY ticket_trail.PickT_Num ORDER BY 
ticket_trail.time_stamp Asc) as RowNum
FROM
ticket_trail
)
SELECT 
ticket.RowNum,ticket.PickT_Num AS 'Pick Ticket'
,ticket.ID AS id1
,ticket.ticket_status as Ticket_Status
,ticket.time_stamped as start_time 
,Row2.ID id2,ISNULL(Row2.time_stamped,GetDate()) AS "End Time"
,DATEDIFF(MINUTE,ticket.time_stamped,ISNULL(Row2.time_stamped,GetDate()))
From 
ticket left join ticket AS Row2
ON 
ticket.RowNum +1 = Row2.RowNum AND ticket.PickT_Num = Row2.PickT_Num

确定以便Query完美运行!!然而，它并没有讲述整个故事！我需要能够添加另一个条目作为＆＃39; 0＆＃39; RowNum | Pick Ticket | id1 | Ticket_Status | start_time | id2 | End Time | Diff 1 | 4628750 | 65 | Yellow | 2017-11-08 09:24:14.000 | 66 | 2017-11-08 09:24:26.000 | 0 2 | 4628750 | 66 | Green | 2017-11-08 09:24:26.000 | NULL | 2017-11-21 16:33:12.733 | 19149 1 | 4647142 | 78 | Yellow | 2017-11-08 09:28:02.000 | 79 | 2017-11-08 09:28:08.000 | 0 2 | 4647142 | 79 | Flashing | 2017-11-08 09:28:08.000 | 295 | 2017-11-08 14:14:10.000 | 286 3 | 4647142 | 295 | Green | 2017-11-08 14:14:10.000 | NULL | 2017-11-21 16:33:12.733 | 18859 1 | 4647973 | 1 | Blue | 2017-11-08 09:02:04.000 | 21 | 2017-11-08 09:06:05.000 | 4 2 | 4647973 | 21 | Green | 2017-11-08 09:06:05.000 | NULL | 2017-11-21 16:33:12.733 | 19167 1 | 4648017 | 2 | Blue | 2017-11-08 09:02:26.000 | 22 | 2017-11-08 09:05:56.000 | 3 2 | 4648017 | 22 | Green | 2017-11-08 09:05:56.000 | NULL | 2017-11-21 16:33:12.733 | 19168 1 | 4648030 | 41 | Blue | 2017-11-08 09:18:20.000 | 54 | 2017-11-08 09:22:39.000 | 4 2 | 4648030 | 54 | Green | 2017-11-08 09:22:39.000 | NULL | 2017-11-21 16:33:12.733 | 19151来自另一个名为RowNum的表中的每个PickT_Num，该表提供了一个名为Orders_ent的time_stamp

所以我认为它必须是一个Case声明，但我不知道从哪里开始...

输出中可以有Printed，但基本上我正在寻找的是：

NULLS

RowNum | Pick Ticket | id1 | Ticket_Status | start_time | id2 | End Time | Diff 0 | 4628750 | NULL | Printed | 2017-11-08 09:20:14.000 | 65 | 2017-11-08 09:24:14.000 | 4 1 | 4628750 | 65 | Yellow | 2017-11-08 09:24:14.000 | 66 | 2017-11-08 09:24:26.000 | 0 2 | 4628750 | 66 | Green | 2017-11-08 09:24:26.000 | NULL | 2017-11-21 16:33:12.733 | 19149表看起来像这样......

Orders_ent

Answer 1

尝试添加UNION ALL和ORDER BY

... -- your query is here

UNION ALL

SELECT
  0 RowNum,
  e.PickT_Num,
  NULL id1,
  'Printed' Ticket_Status,
  e.Date_Created,
  t.ID id2,
  e.Pick_Ticket_Printed_DATE_Time,
  DATEDIFF(MINUTE,e.Date_Created,ISNULL(e.Pick_Ticket_Printed_DATE_Time,GetDate()))
FROM Orders_ent e
JOIN
  (
    SELECT PickT_Num,ID
    FROM ticket
    WHERE RowNum=1
  ) t
ON e.PickT_Num=t.PickT_Num

ORDER BY 'Pick Ticket',RowNum

如果Time首先使用ROW_NUMBER PARTITION，则将Row插入第二个表中的select语句
