SQL Jet Access、插入列和排序依据

Question

我通过 excel 使用 Microsoft.ACE.OLEDB.12.0 连接在我的工作簿中进行内部查询。

如何在查询中插入包含年份的列 Year 并对其进行排序，以使它们不在一起。所以他们会一个接一个地重复？

我已经添加了 Year 列，但现在排序是个问题。

这是我当前的查询

select [Data Type], [Currency], [Book Name], [1987] as Value
from [stage2$]
UNION ALL
select [Data Type], [Currency], [Book Name], [1990]
from [stage2$]

当前数据：

+--------------------------------+----------+-------+---------------+
|           Data Type            | Currency | Name  |   value       |
+--------------------------------+----------+-------+--------------
| Missing Non Historical Results | BSD      | Carib | (279)         |
| Missing Non Historical Results | BSD      | Carib |   18          |
| Missing Non Historical Results | BSD      | Carib |   898         |
| Missing Non Historical Results | BSD      | Carib |  (50)         |
+--------------------------------+----------+-------+---------------+

预期结果：

+--------------------------------+----------+-------+---------------+---------+
|           Data Type            | Currency | Name  | Year          |  value  |
+--------------------------------+----------+-------+---------------+---------+
| Missing Non Historical Results | BSD      | Carib |          1987 |  (279)  |
| Missing Non Historical Results | BSD      | Carib |          1990 |  898    |
| Missing Non Historical Results | BSD      | Carib |          1987 |  18     |
| Missing Non Historical Results | BSD      | Carib |          1990 |  (50)   |
+--------------------------------+----------+-------+---------------+---------+

您可以在 select 语句中再添加一列：

select [Data Type], [Currency], [Book Name], '1987' as Year, [1987] as Value
from [stage2$]
UNION ALL
select [Data Type], [Currency], [Book Name], '1990' as Year, [1990]
from [stage2$]
order by Year
