将列转换为SSIS中的行

Question

我的数据看起来像

Viral Impressions   Paid Impressions    Organic Impressions
123                   5678                          34566

我希望它采用这种格式。

         Impressions
Viral        123
Paid         5678
Organic       34566

如何使用Pivot unpivot在SSIS中执行此操作

Answer 1

作为UNPIVOT的替代方案，您可以使用UNION ALL：

 Select 'viral' as col, [viral impressions] as impressions
 From yourtable
 Union all
 Select 'paid' as col, [paid impressions] as impressions
 From yourtable
 Union all
 Select 'organic' as col, [organic impressions] as impressions
 From yourtable

请参阅SQL Fiddle with Demo

给出结果：

|     COL | IMPRESSIONS |
-------------------------
|   viral |         123 |
|    paid |        5678 |
| organic |       34566 |

Answer 2

使用UNPIVOT表格运算符：

SELECT 
  value, 
  Impressions
FROM TableName
UNPIVOT
(
  Impressions
  FOR value IN([Viral], 
               [Paids], 
               [Organic])
) u;

SQL Fiddle Demo

这假设列的名称存储为Viral | Paid | Organic。如果这些列的名称为Viral Impressions | Paid Impressions | Organic Impressions那么您可以执行此操作：

WITH CTE
AS
(
  SELECT value, Impressions
  FROM Table1
  UNPIVOT
  (
     Impressions
     FOR value IN([Viral Impressions], 
                  [Paid Impressions], 
                  [Organic Impressions])
  ) u
)
SELECT 
  REPLACE(value, ' Impressions', '') Value, 
  Impressions
FROM CTE;
