我试图在SQL Server中按Date
排序我面临一个奇怪的问题。我应该解释2个案例,以帮助您理解我的问题。
案例1:
select [MonthName]
from prod.[dim date]
where F_Year = 2014
order by [Date]
我的输出:
june june june july july july july august
// Here I get duplicates but order by is working as expected
案例2:尝试使用" distinct" 删除重复项
select distinct [MonthName]
from prod.[dim date]
where F_Year = 2014
order by [Date]
我的输出:
August july june
// Order By not working as expected (ordering alphabetical wise ) .
感谢任何解决方法

首先,您的查询似乎正在处理一个表,其中3个字段表示可能是单个日期,或者可能是2个 - 没有结构很难分辨,但我可以看到:F_Year,[Date]& [MONTHNAME]。因此,如果这些实际上代表一个日期,则恢复到该单个日期并使用格式来确定F_Year和MonthName。
其次,请查看这些帖子,以获得对您问题的可能答案:
