Question

我是SQL的新手并且正在学习编写Quires。帮我。在此先感谢。

实际上，我正在使用此query

对以下结果表进行竞争

select * from 
(select case Temp 
           when '0' then 'Temperature' 
           when '1' then 'PULSE RATE/MIN'
           when '2' then 'RESPIRATION/MIN' 
           when '3' then 'BLOOD PRESSURE' 
           when '4' then 'URINE' 
        end as Temp,
        Value, 
        convert(nvarchar(15),Date,103) Date,
       concat(case Time 
                 when '0' then '2' 
                 when '1' then '6' 
                 when '2' then '10' 
              end,' ',
              case AMPM 
                 when '0' then 'AM' 
                 when '1' then 'PM' 
              end)[Tim]
from HMS_Chart_Clinical
where status = '0' and IPNO='21460') as s
pivot(max(Value) for [date] in ([07/11/2016],[08/11/2016])) as datapivot
pivot(max(Tim) for [Tim] in ([2 AM],[6 AM],[10 AM],[2 PM],[6 PM],[10 PM])) as datapivot

但我需要下面的结论表。

Answer 1

你不能拥有那张桌子。您可以做的最好是创建此列，并在UI中添加aditional标头。

 07/11/2016 02:00 am
 07/11/2016 06:00 am
 07/11/2016 10:00 am
 07/11/2016 02:00 pm
 07/11/2016 06:00 pm
 07/11/2016 10:00 pm
 08/11/2016 02:00 am
 08/11/2016 06:00 am
 08/11/2016 10:00 am
 08/11/2016 02:00 pm
 08/11/2016 06:00 pm
 08/11/2016 10:00 pm

因此请将您的查询更改为

concat(convert(nvarchar(15),Date,103) Date,
       case Time 
             when '0' then '2' 
             when '1' then '6' 
             when '2' then '10' 
       end,' ',
       case AMPM 
             when '0' then 'AM' 
             when '1' then 'PM' 
       end) as [Tim]

并使用单个支点

pivot(max(Tim) for [Tim] in ([07/11/2016 02 AM],
                             [07/11/2016 06 AM],
                             [07/11/2016 10 AM],
                             [07/11/2016 02 PM],
                             [07/11/2016 06 PM],
                             [07/11/2016 10 PM]) .....) as datapivot

我遇到与此问题无关的问题。所以不要过多地影响你原来的思维方式：

DECLARE @HMS_Chart_Clinical TABLE (
 [ID]     INT PRIMARY KEY NOT NULL IDENTITY (1,1),
 [Temp]   INT, --0,1,2,3,4
 [Value]  INT,
 [Date]   DATE,
 [Time]   INT,   -- 0,1,2
 [AMPM]   INT,   -- 0,1
 [status] BIT,
 [IPNO]   INT
)

INSERT @HMS_Chart_Clinical ([Temp], [Value], [Date], [Time], [AMPM], [status], [IPNO]) VALUES (3, 125, '20161107', 2, 0, 0, 21460)
INSERT @HMS_Chart_Clinical ([Temp], [Value], [Date], [Time], [AMPM], [status], [IPNO]) VALUES (1, 26, '20161108', 2, 1, 0, 21460)
INSERT @HMS_Chart_Clinical ([Temp], [Value], [Date], [Time], [AMPM], [status], [IPNO]) VALUES (1, 99, '20161107', 1, 1, 0, 21460)
INSERT @HMS_Chart_Clinical ([Temp], [Value], [Date], [Time], [AMPM], [status], [IPNO]) VALUES (0, 106, '20161107', 0, 0, 0, 21460)

IF OBJECT_ID('tempdb..#PivotSource') IS NOT NULL
    DROP TABLE #PivotSource

  CREATE TABLE #PivotSource
  (
   Temp       VARCHAR(MAX),
   Value      INT,
   [DateTime] VARCHAR(MAX)
  )
  INSERT INTO #PivotSource
  SELECT CASE Temp 
           WHEN '0' THEN 'Temperature' 
           WHEN '1' THEN 'PULSE RATE/MIN'
           WHEN '2' THEN 'RESPIRATION/MIN' 
           WHEN '3' THEN 'BLOOD PRESSURE' 
           WHEN '4' THEN 'URINE' 
         END AS Temp,
         Value, 
         CONVERT(NVARCHAR(15),[Date],103) + ' ' + 
         CASE [Time] 
           WHEN '0' THEN '2' 
           WHEN '1' THEN '6' 
           WHEN '2' THEN '10' 
         END + ' ' + 
         CASE AMPM 
            WHEN '0' THEN 'AM' 
            WHEN '1' THEN 'PM' 
         END AS [DateTime]
    FROM @HMS_Chart_Clinical
   WHERE [status] = '0' 
     AND IPNO='21460' 

DECLARE @PivotColumns NVARCHAR(MAX)

;WITH AllDatesAndTimes AS (
    SELECT DISTINCT [Date], 
           TimeString.[Time],
           TimeString.[SortOrder]
      FROM @HMS_Chart_Clinical
CROSS JOIN (SELECT '2 AM'  AS [Time], 0 AS SortOrder
  UNION ALL SELECT '6 AM'  AS [Time], 1 AS SortOrder
  UNION ALL SELECT '10 AM' AS [Time], 2 AS SortOrder
  UNION ALL SELECT '2 PM'  AS [Time], 3 AS SortOrder
  UNION ALL SELECT '6 PM'  AS [Time], 4 AS SortOrder
  UNION ALL SELECT '10 PM' AS [Time], 5 AS SortOrder) TimeString
)  
SELECT @PivotColumns = COALESCE(@PivotColumns + '], [', '') + CONVERT(NVARCHAR(15),[Date],103) + ' ' + [Time]
FROM AllDatesAndTimes
ORDER BY [Date],[SortOrder]

DECLARE @PivotQuery NVARCHAR(MAX) =  'SELECT * FROM #PivotSource  PIVOT(MAX(Value) FOR [DateTime] IN ([' + @PivotColumns + '])) AS DATAPIVOT'
EXEC(@PivotQuery)
