SQL Server中實現時間按月,日,小時等時間分組查詢

直接附上代碼：

--按照月份統計
select count(id) groupCount,datepart(mm,addtime) [Month]
from tableName
where addtime between '2007/09/08 09:10:43' and '2007/10/09 04:32:37'
group by datepart(mm,addtime)
--按照日統計
select count(id) groupCount,datepart(dd,addtime) [Day]
from tableName
where addtime between '2007/09/08 09:10:43' and '2007/10/09 04:32:37'
group by datepart(dd,addtime)
--按照小時統計
select count(id) groupCount,datepart(hh,addtime) [Hour]
from tableName
where addtime between '2007/09/08 09:10:43' and '2007/10/09 04:32:37'
group by datepart(hh,addtime)

--按年月分組
select datename(year,addtime)+datename(month,addtime)as 年月 ,sum(id) as 統計 from abc group by datename(year,addtime)+datename(month,addtime)

--按照旬統計
select case (datepart(day,addtime)-1)/10 when 0 then '上旬' when 1 then '中旬' else '下旬' end as 旬,
 sum(id) as 統計 
 from tableName group by 
 case (datepart(day,addtime)-1)/10 when 0 then '上旬' when 1 then '中旬' else '下旬' end 

 --按 年+旬 分組統計
 select datename(year,addtime)+datename(month,addtime)+case (datepart(day,addtime)-1)/10 when 0 then '上旬' when 1 then '中旬' else '下旬' end as 日期, sum(id) as 統計
 from tableName 
 group by datename(year,addtime)+datename(month,addtime)+case (datepart(day,addtime)-1)/10 when 0 then '上旬' when 1 then '中旬' else '下旬' end 

 

如果查詢出來的結果 年或月變成英文的話，可以使用下面這種方式轉

 SELECT CONVERT(varchar(7), GETDATE(), 102) 

示例代碼：

 select * from (
select CONVERT(varchar(7), AddTime, 102) as 年月 ,count(UserID) as 統計 from tableName
where RoleID = 2 and AddTime > '2016-01-01 00:00:00'
 group by CONVERT(varchar(7), AddTime, 102)
 ) a order by 年月 asc
