最笨的方法
declare @timeend varchar(30),
@timestart varchar(30),
@subs varchar(2)
--計算統計的開始時間和結束時間
set @time=convert(varchar(30),@time,120)
--select @timestart=rtrim(ltrim(remark)) from dbo.baseinfo where baseinfoid=139--獲取分隔時間
select @timeend=rtrim(ltrim(remark)) from dbo.baseinfo where baseinfoid=140
set @subs=month(@time)--獲取月份
if(len(@subs)=1)
set @timeend=cast(year(@time) as varchar(4))+'-0'+@subs+'-'+@timeend
else
set @timeend=cast(year(@time) as varchar(4))+'-'+@subs+'-'+@timeend
set @subs=cast(cast(@subs as int)-1 as varchar(2))
if(len(@subs)=1)
set @timestart=cast(year(@time) as varchar(4))+'-0'+@subs+'-'+@timestart
else
set @timestart=cast(year(@time) as varchar(4))+'-'+@subs+'-'+@timestart
--select @timestart,@timeend
簡化：declare
@timestart varchar(30),
@timeend varchar(30),
@time varchar(30),
@detpid varchar(36)
set @detpid='43b5d11c-e8be-4cfd-ac99-ddff342ca7ad'
set @time='2010-06-02'
select @timeend=rtrim(ltrim(remark)) from dbo.baseinfo where baseinfoid=140
set @timeend=replace(@time,substring(@time,9,2),@timeend)
set @timestart=convert(varchar(30),dateadd(day,1,dateadd(month, -1, convert(datetime,@timeend,120))),120)
select cast(sum(convert(float,isnull(scores,100))/100*convert(float,remark))/sum(convert(float,remark)*convert(float,isnull(complete,1)))*100 as decimal(9,4)) as source
from view_getworkscore
where timeend between @timestart and @timeend and detpid=@detpid
select dateadd(month, -1, getdate())--上乙個月
select dateadd(day, -1, getdate()) --前一天
select getdate()
取前一天或後一天 乙個月時間

strtotime 獲取上乙個月
1.案例 strtotime結合 1 month,1 month,next month 有時候會出現錯誤 date y m d strtotime 1 month 輸出 2018 07 01 1 month 程式設定 30天，相當於7月31日 30天得7月30號 var dump date y m ...
