使用光标将数据垂直插入到临时表中

Question

如上所述。 我已经在SQL中创建了2个临时表，需要垂直插入才能完成所有列，但是据我了解，您只能水平插入数据吗？

有没有解决的办法？

范例：

ForgeinKey  |  Q1  |  Q2  |  Q3  |  Q4  |  Q5  | 
   1234     |    1 |     1|    0 |    2 |     0|
   1235     |    0 |     2|    1 |    2 |     0|
   1236     |    2 |     2|    0 |    0 |     1|

我认为会发生以下情况：

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）的前几列中都有所有数据，但此后我有22列，应该用另一个临时表（1）中的数据填充。

在临时表（1）中，所有数据都水平显示：

Answers  |  Questions  |  ForeignKey
   1     |      Q1     |       1234     
   1     |      Q2     |       1234  
   0     |      Q3     |       1234  
   2     |      Q4     |       1234  
   0     |      Q5     |       1234  

如上所示，我需要临时表（1）才能使用外键识别行以垂直填充临时表（2）：

ForgeinKey  |  Q1  |  Q2  |  Q3  |  Q4  |  Q5|
   1234     |    1 |     1|    0 |     2|   0|
   1235     |    0 |     2|    1 |     2|   0|
   1236     |    2 |     2|    0 |     0|   1|

这是我目前与bluefeet解决方案一起使用的代码：

您的问题尚不完全清楚，但是您可以应用UNPIVOT函数将数据从列转换为行，或者应用PIVOT函数将行转换为列。

一旦数据以所需的格式获取，您就可以根据需要INSERT它。

枢：

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;

志愿人员：

select ForgeinKey, questions, answers
from table2
unpivot
(
  answers
  for questions in (Q1, Q2, Q3, Q4, Q5)
) unpiv
