① sql月份累计
sql语句为：update表set日期字段=dateadd(m,1,日期字段)定义和用法DATEADD()函数在日期中添加或减去指定的时间间隔。语法DATEADD(datepart,number,date)date参数是合法的日期表达式。number是您希望添加的间隔数；对于未来的时间，此数是正数，对于过去的时间，此数是负数。

⑥ Oracle中的SQL查询语句：如何按照表中不同部门，按照录入时间分12个月份统计求和。
--希望解决了楼主的问题
select bm,sum(case when to_char(time,'MM')='01' then fz else 0 end ) 1月份fz合计,
sum(case when to_char(time,'MM')='02' then fz else 0 end ) 2月份fz合计,
sum(case when to_char(time,'MM')='03' then fz else 0 end ) 3月份fz合计,
sum(case when to_char(time,'MM')='04' then fz else 0 end ) 4月份fz合计,
sum(case when to_char(time,'MM')='05' then fz else 0 end ) 5月份fz合计,
sum(case when to_char(time,'MM')='06' then fz else 0 end ) 6月份fz合计,
sum(case when to_char(time,'MM')='07' then fz else 0 end ) 7月份fz合计,
sum(case when to_char(time,'MM')='08' then fz else 0 end ) 8月份fz合计,
sum(case when to_char(time,'MM')='09' then fz else 0 end ) 9月份fz合计,
sum(case when to_char(time,'MM')='10' then fz else 0 end ) 10月份fz合计,
sum(case when to_char(time,'MM')='11' then fz else 0 end ) 11月份fz合计,
sum(case when to_char(time,'MM')='12' then fz else 0 end ) 12月份fz合计 from bmfz
group by bm
⑦ SQL 库存明细账月份累计与合计
如果三楼可以的话你可以这样做：
select rq,sl,je from kc where datepart(month,rq)=10 and datepart(year,rq)=2008
union all
select '10月累计',sum(sl),sum(je)from kc where datepart(month,rq)=10 and datepart(year,rq)=2008
union all
select '10月合计',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月累计',sum(sl),sum(je)from kc where datepart(month,rq)=11 and datepart(year,rq)=2008
union all
select '11月合计',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月累计',sum(sl),sum(je)from kc where datepart(month,rq)=12 and datepart(year,rq)=2008
union all
select '12月合计',sum(sl),sum(je)from kc where datepart(month,rq)<=12 and datepart(year,rq)=2008
⑧ sql循环求和 条件：月份+3=当前月
--楼主并没有说清楚查询条件，所以如下只是猜测：
select
SUM(isnull(intA,0))
as
合计
from
表1
where
Month(AddDate(Month,3,Date1))=Month(GetDate())
--对月份加上3得到的月份数等于当前系统日期的月份数
的记录集合中的
intA求和
比如说当前日期是
2015.5.20，那么Month(GetDate())就是5;
所以只有Date1的月份是2的才会查出来并合计，这种是没有考虑年的，如果要考虑年的，做条件就不是这样的。
⑨ SQL按月份累计求和
用自定义函数
create FUNCTION getsum(@月份 int)
RETURNS int
AS
begin
declare @sum int
select @sum=sum(个数) from 表名 where 月份<=@月份
return @sum
end
然后查询
select 月份,dbo.getsum(月份) as 个数 from 表名
⑩ sql 月份的累计
可以更改为同年的，统计月份小于等于指定月份的值就可以了。
例如：取2017年10月的月份累计值：
selectsum(quality)(time)=2017andMonth(time)<=10
