① sql月份累計
sql語句為：update表set日期欄位=dateadd(m,1,日期欄位)定義和用法DATEADD()函數在日期中添加或減去指定的時間間隔。語法DATEADD(datepart,number,date)date參數是合法的日期表達式。number是您希望添加的間隔數；對於未來的時間，此數是正數，對於過去的時間，此數是負數。

③ sql按月求和語句怎麼寫
使用 case when 配合 sum來統計。
如圖表a2
④ sql 語句怎麼按照月去統計數據！
Select foodid, month(datetime), sum(mak) from [tablename1] where year(datetime) = 2013 group by foodid,month(datetime)
⑤ sql怎麼將當月每一天的數據相加，求總和

⑥ Oracle中的SQL查詢語句：如何按照表中不同部門，按照錄入時間分12個月份統計求和。
--希望解決了樓主的問題
select bm,sum(case when to_char(time,'MM')='01' then fz else 0 end ) 1月份fz合計,
sum(case when to_char(time,'MM')='02' then fz else 0 end ) 2月份fz合計,
sum(case when to_char(time,'MM')='03' then fz else 0 end ) 3月份fz合計,
sum(case when to_char(time,'MM')='04' then fz else 0 end ) 4月份fz合計,
sum(case when to_char(time,'MM')='05' then fz else 0 end ) 5月份fz合計,
sum(case when to_char(time,'MM')='06' then fz else 0 end ) 6月份fz合計,
sum(case when to_char(time,'MM')='07' then fz else 0 end ) 7月份fz合計,
sum(case when to_char(time,'MM')='08' then fz else 0 end ) 8月份fz合計,
sum(case when to_char(time,'MM')='09' then fz else 0 end ) 9月份fz合計,
sum(case when to_char(time,'MM')='10' then fz else 0 end ) 10月份fz合計,
sum(case when to_char(time,'MM')='11' then fz else 0 end ) 11月份fz合計,
sum(case when to_char(time,'MM')='12' then fz else 0 end ) 12月份fz合計 from bmfz
group by bm
⑦ SQL 庫存明細賬月份累計與合計
如果三樓可以的話你可以這樣做：
select rq,sl,je from kc where datepart(month,rq)=10 and datepart(year,rq)=2008
union all
select '10月累計',sum(sl),sum(je)from kc where datepart(month,rq)=10 and datepart(year,rq)=2008
union all
select '10月合計',sum(sl),sum(je)from kc where datepart(month,rq)<=10 and datepart(year,rq)=2008
union all
select rq,sl,je from kc where datepart(month,rq)=11 and datepart(year,rq)=2008
union all
select '11月累計',sum(sl),sum(je)from kc where datepart(month,rq)=11 and datepart(year,rq)=2008
union all
select '11月合計',sum(sl),sum(je)from kc where datepart(month,rq)<=11 and datepart(year,rq)=2008
union all
select rq,sl,je from kc where datepart(month,rq)=12 and datepart(year,rq)=2008
union all
select '12月累計',sum(sl),sum(je)from kc where datepart(month,rq)=12 and datepart(year,rq)=2008
union all
select '12月合計',sum(sl),sum(je)from kc where datepart(month,rq)<=12 and datepart(year,rq)=2008
⑧ sql循環求和 條件：月份+3=當前月
--樓主並沒有說清楚查詢條件，所以如下只是猜測：
select
SUM(isnull(intA,0))
as
合計
from
表1
where
Month(AddDate(Month,3,Date1))=Month(GetDate())
--對月份加上3得到的月份數等於當前系統日期的月份數
的記錄集合中的
intA求和
比如說當前日期是
2015.5.20，那麼Month(GetDate())就是5;
所以只有Date1的月份是2的才會查出來並合計，這種是沒有考慮年的，如果要考慮年的，做條件就不是這樣的。
⑨ SQL按月份累計求和
用自定義函數
create FUNCTION getsum(@月份 int)
RETURNS int
AS
begin
declare @sum int
select @sum=sum(個數) from 表名 where 月份<=@月份
return @sum
end
然後查詢
select 月份,dbo.getsum(月份) as 個數 from 表名
⑩ sql 月份的累計
可以更改為同年的，統計月份小於等於指定月份的值就可以了。
例如：取2017年10月的月份累計值：
selectsum(quality)(time)=2017andMonth(time)<=10
