由于业务需求数据显示的年度报表数值时每日采集的整点数据的平均值，然而现场人员给我们反馈回来直接就是平均值，但是数据库中原始存储的数据是每日每个时间段的整点数值。
SWS_ST_SPB_P 原始数据每天都有数个整点数据：

SWS_ST_SPB_P_copy 这是我们修改后每日的平均值每天只有一条数据：

那么我所要解决的问题是将SWS_ST_SPB_P 原始数据中需要修改的数据根据修改过后的SWS_ST_SPB_P_copy 中的数据等比例的缩放。

-- 删除所要修改的原始数据
DELETE sc FROM SWS_ST_SPB_P sc
inner join SWS_ST_SPB_P_copy s
on s.stcd = sc.stcd 
and convert(varchar(10), s.tm, 126)  = convert(varchar(10), sc.tm, 126)
and s.mpcd = sc.mpcd  
where s.tm >='2017-09-01 00:00:00' and s.tm < '2017-10-01 00:00:00'  
and s.mpcd = sc.mpcd

-- 增加的字段
 ALTER TABLE SWS_ST_SPB_P_copy add r1sum decimal,r2sum decimal,r3sum decimal,rcount decimal ;
 SELECT * INTO SWS_ST_SPB_P_copy1 FROM SWS_ST_SPB_P;

-- 创建临时表 aaa

LEFT JOIN SWS_ST_SPB_P_copy sc on s.stcd = sc.stcd

 GROUP BY t.mpcd ,convert(varchar(10), t.tm, 126)
