如何使用sql查询获取此输出，我有两个表ServayQues1和ServayQuesAns1

Question

select A.QueId,Question,Answer from 
ServayQues1 as S inner join ServayQuesAns1 as A
on S.QueId=A.QueId

 QueId |    Question  | Answer
  ----------------------------
   1    test            Ok 
   1    test            not bad
   1    test            need to be improve
  ----------------------------

我的预期输出低于

  QueId   |  Question    |   answer1   |  answer2   |   answer3   
   --------------------------------------------------------------------------
   1          test               Ok          not bad     need to be improve  
   ---------------------------------------------------------------------------

如何获得此输出？

Answer 1

希望这就是你所需要的。

DECLARE @PivotColumnHeaders VARCHAR(MAX)

SELECT @PivotColumnHeaders =  COALESCE(
@PivotColumnHeaders + ',[' + cast([answer] as varchar) + ']',
'[' + cast([answer] as varchar)+ ']')
 FROM (SELECT DISTINCT Answer  from 
 ServayQues1 as S inner join ServayQuesAns1 as A
 on S.QueId=A.QueId) s


DECLARE @PivotTableSQL NVARCHAR(MAX)
SET @PivotTableSQL = N'
SELECT *
FROM
(
SELECT A.QueId,Question,Answer 
FROM ServayQuesAns1 A inner join
ServayQues1 q on q.QueId= a.QueId
) AS source
PIVOT
(
MAX([Answer])
FOR [Answer] IN (
  ' + @PivotColumnHeaders + '
)
) AS PivotTable
'
print @PivotTableSQL

EXECUTE(@PivotTableSQL)
