SQL查询中枢轴列中的枢轴

Question

我是SQL的新手，学习写作Quires。帮我。提前致谢。

其实我用这个query

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 

geeting以下合力表，但我需要的波纹管合力表。

Answer 1

你不能有一个表。您可以做的最好的是创建此列，并在用户界面中添加附加标题。

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 

所以您的查询更改为

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] 

，并使用单枢轴

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 

Answer 2

我有这一点，是与问题无关的问题。所以不会影响你原来的想法太多：

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)
