Sql 将两个查询联接到表中的列中

我需要帮助修改下面的查询。我正在尝试创建如下表：

| Jan 2014 | Feb 2014 |
|   7.5    |    8     |

但我最终得到的是：

| Jan 2014 |
|   7.5    |
|     8    |

有没有办法将这两个（可能更多）查询连接到列而不是行中？顺便说一下，我正在使用MS Access。先谢谢你

我当前的查询：

SELECT * FROM
(SELECT AVG([Length of Service in Years including Partial Year]) AS Jan2014 
 FROM [January 2014 HC] AS A) 
UNION ALL 
(SELECT AVG([Length of Service in Years including Partial Year]) AS Feb2014 
 FROM [February 2014 HC] AS B)

谢谢NoDisplayName的回答，我想我明白了

因为两个查询都只返回一行，所以您可以这样做

select 
(SELECT AVG([Length of Service in Years including Partial Year]) 
 FROM [January 2014 HC]) AS Jan2014 , 
(SELECT AVG([Length of Service in Years including Partial Year]) 
 FROM [February 2014 HC]) AS Feb2014

我想我明白了！我把你的答案改了一点，让它在access中工作。我在第一次选择后添加了“*FROM”，它就成功了。非常感谢你的帮助！我想我明白了！我把你的答案改了一点，让它在access中工作。我在第一次选择后添加了“*FROM”，它就成功了。非常感谢你的帮助！我想我明白了！我把你的答案改了一点，让它在access中工作。我在第一次选择后添加了“*FROM”，它就成功了。非常感谢你的帮助！我想我明白了！我把你的答案改了一点，让它在access中工作。我在第一次选择后添加了“*FROM”，它就成功了。非常感谢你的帮助！
