问题描述
大家好!
我想首先感谢所有花时间查看此主题并尝试提供帮助的人。
我会简短,并切入点:
我在MS Access中有一个表,它包含2列兴趣 - 县和TGTE(地热能类型)。列TGTE是VARCHAR类型,它可以有两个值中的一个,以便更容易让它说它是L或H.
我需要创建SQL查询这显示了一个下面描述的结果(代码标签是为了更清晰的外观):
贝娄是表的一部分:
县| TGTE | ......其他领域|
--------------------
首先| L |
首先| L |
首先| H |
第二个| H |
第三| L |
我需要一个结果查询,显示每个县的不同TGTE的数量,如下所示:
县| TGTE = L | TGTE = H |
---------------------------------------------- -
首先| 2 | 1 |
第二个| 0 | 1 |
第三| 1 | 0 |
如何创建显示上面描述的期望结果?
Hello everyone!
I would like to start by saying thanks to everyone who takes some time to view this thread and try to help.
I will be brief, and cut to the point:
I have a table in MS Access, it contains 2 columns of interest- County, and TGTE (Type Of Geothermal Energy ). Column TGTE is of type VARCHAR and it can have 1 of two values, to make it easier let's say it is either L or H.
I need to create SQL query that shows a result which is described bellow ( code tags are for clearer look ):
Bellow is the part of the table:
County | TGTE | ... other fields | -------------------- First | L | First | L | First | H | Second | H | Third | L |
I need a resulting query that shows the count of distinct TGTE in every County like this:
County | TGTE = L | TGTE = H | ------------------------------------------------ First | 2 | 1 | Second | 0 | 1 | Third | 1 | 0 |
How can I create query that displays the desired result described above ?
