Question

我是SQL服务器的新手，但发现它非常有用。

现在我正在与我需要重新排列的sql结构作斗争。

我有一个有6列的数据库：

Call ID and Question1, 2, 3, 4, 5, 6

呼叫ID是接听电话的人，因为询问了6个问题，同一个呼叫ID可以存在于呼叫ID列中的多个位置。

为了创建唯一的呼叫ID列表，我已经进行了查询：

SELECT DISTINCT [call_id]
FROM [ConnectCallData_26391].[dbo].[call_events]

我现在需要做的事情：

我需要使用来自CALL ID DISCTINCT查询的结果，并将问题1-6与调用ID对齐，以便唯一的调用ID只有一行，所有问题如前所述都列在第2-6行！

非常需要帮助!!

亲切的问候丹尼尔

这是用于分隔问题的查询：

select 
      ,[menue_key]
      ,dte_start 
      ,[dte_updated]
      ,[rec_id]
      ,[call_id] 
      ,[duration_tot_sec] 
      ,iif([menue_key] ='SYS FLX HAC survey_question_1' OR [menue_key] ='SYS FLX Flextur survey_question_1',[menue_choice],'' ) as 'Hvad er din alder?'
      ,iif([menue_key] ='SYS FLX HAC survey_question_2' OR [menue_key] ='SYS FLX Flextur survey_question_2',[menue_choice],'' ) as 'Hvilket postnummer bor du i?'
      ,iif([menue_key] ='SYS FLX HAC survey_question_3' OR [menue_key] ='SYS FLX Flextur survey_question_3',[menue_choice],'' ) as 'Hvor tilfreds er du generelt med at benytte den anvendte ordning?'
      ,iif([menue_key] ='SYS FLX HAC survey_question_4' OR [menue_key] ='SYS FLX Flextur survey_question_4',[menue_choice],'' ) as 'Hvis du ikke havde den anvendte ordning til rådighed, hvad ville du så benytte som erstatning for dine rejser?'
      ,iif([menue_key] ='SYS FLX HAC survey_question_5' OR [menue_key] ='SYS FLX Flextur survey_question_5',[menue_choice],'' ) as 'Hvad er formålet med den tur du lige har bestilt?'
      ,iif([menue_key] ='SYS FLX HAC survey_question_6' OR [menue_key] ='SYS FLX Flextur survey_question_6',[menue_choice],'' )as 'Hvorfor bestiller du ikke din tur via internettet?'

  FROM [ConnectCallData_26391].[dbo].[call_events] 
  where menue_key in ('SYS FLX HAC survey_question_1','SYS FLX HAC survey_question_2', 'SYS FLX HAC survey_question_3',
  'SYS FLX HAC survey_question_4','SYS FLX HAC survey_question_5','SYS FLX HAC survey_question_6','SYS FLX Flextur survey_question_1','SYS FLX Flextur survey_question_2', 'SYS FLX Flextur survey_question_3',

你需要转动

;WITH Prepivot AS

    select 
          [call_id] AS Call_ID
          ,[menue_key]
          ,[menue_choice]
      FROM 
        [ConnectCallData_26391].[dbo].[call_events] 
      where 
        menue_key in (
            'SYS FLX HAC survey_question_1',
            'SYS FLX HAC survey_question_2', 
            'SYS FLX HAC survey_question_3',
            'SYS FLX HAC survey_question_4',
            'SYS FLX HAC survey_question_5',

SELECT

        MAX(N.[menue_choice]) FOR N.[menue_key] IN (

或条件聚合：

select 
      [call_id] 
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_1' OR [menue_key] ='SYS FLX Flextur survey_question_1' THEN [menue_choice] END) as 'Hvad er din alder?'
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_2' OR [menue_key] ='SYS FLX Flextur survey_question_2' THEN [menue_choice] END) as 'Hvilket postnummer bor du i?'
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_3' OR [menue_key] ='SYS FLX Flextur survey_question_3' THEN [menue_choice] END) as 'Hvor tilfreds er du generelt med at benytte den anvendte ordning?'
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_4' OR [menue_key] ='SYS FLX Flextur survey_question_4' THEN [menue_choice] END) as 'Hvis du ikke havde den anvendte ordning til rådighed, hvad ville du så benytte som erstatning for dine rejser?'
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_5' OR [menue_key] ='SYS FLX Flextur survey_question_5' THEN [menue_choice] END) as 'Hvad er formålet med den tur du lige har bestilt?'
      ,MAX(CASE WHEN  [menue_key] = 'SYS FLX HAC survey_question_6' OR [menue_key] ='SYS FLX Flextur survey_question_6' THEN [menue_choice] END) as 'Hvorfor bestiller du ikke din tur via internettet?'
