以下是动态执行操作的方法：
create table #t1(QID int, Question char(10))
insert #t1 values
(1, 'Question 1'),
(2, 'Question 2'),
(3, 'Question 3'),
(4, 'Question 4'),
(5, 'Question 5')
create table #t2 (QID int, Answer char(3), Parent int)
insert #t2 values
(1, 'Yes', 123),
(2, 'No ', 123),
(3, 'No ', 123),
(4, 'Yes', 123),
(5, 'Yes', 123),

(2, 'Yes', 124),
(3, 'No ', 124),
(4, 'No ', 124),
(5, 'No ', 124)
declare @collist nvarchar(max)
SET @collist = stuff((select distinct ',' + QUOTENAME(Question)
FROM #t1 -- your table here
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select @collist
declare @q nvarchar(max)
set @q = '
