如上所述。我在SQL中创建了2个临时表，需要垂直插入才能完成所有列，但据我所知，你只能水平插入数据？
有解决方法吗？
示例：
ForgeinKey | Q1 | Q2 | Q3 | Q4 | Q5 |
1234 | 1 | 1| 0 | 2 | 0|
1235 | 0 | 2| 1 | 2 | 0|
1236 | 2 | 2| 0 | 0 | 1|
我认为会发生什么事情是这样的：
ForgeinKey | Q1 | Q2 | Q3 | Q4 | Q5 |
1234 | 1 |NULL | NULL | NULL| NULL|
1234 |NULL | 1 | NULL | NULL| NULL|
1234 |NULL |NULL | 0 | NULL| NULL|
1234 |NULL |NULL | NULL | 2 | NULL|
1234 |NULL |NULL | NULL | NULL| 0 | (etc)
目前我的临时表（2）的前几个颜色中包含所有数据，但之后我有22个颜色，我应该用另一个临时表（1）中的数据填充。
在临时表（1）中，我将所有数据水平显示：
Answers | Questions | ForeignKey
1 | Q1 | 1234
1 | Q2 | 1234
0 | Q3 | 1234
2 | Q4 | 1234
0 | Q5 | 1234
如上图所示，我需要临时表（1）使用外键垂直填充临时表（2）以识别行：
ForgeinKey | Q1 | Q2 | Q3 | Q4 | Q5|
1234 | 1 | 1| 0 | 2| 0|
1235 | 0 | 2| 1 | 2| 0|
1236 | 2 | 2| 0 | 0| 1|
这是我目前使用bluefeet解决方案的代码：

这样做时我仍然会遇到错误。
答案 0 :(得分：1)
您的问题并不完全清楚，但您可以应用UNPIVOT函数将数据从列转换为行，或应用PIVOT函数将行转换为列。
一旦数据以您需要的格式获得，您可以根据需要INSERT。
<强> PIVOT：
select ForeignKey, Q1, Q2, Q3, Q4, Q5
from
(
select ForeignKey, questions, answers
from table1
) src
pivot
(
max(answers)
for questions in (Q1, Q2, Q3, Q4, Q5)
) piv;
<强> UNPIVOT：
select ForgeinKey, questions, answers
from table2
unpivot
(
answers
for questions in (Q1, Q2, Q3, Q4, Q5)
) unpiv
