计算订单签收率的sql查询思路与过程(涉及百分比和四舍五入)

领导提出一个签收率需求，想要通过数据库达到excel中表现的形式，提高计算速度和工作效率，

如下形式：

数据库中表数据结构：

部分数据如下：

sql语句思路如下：

-- 1.已签收：以物流反馈管道，状态分组，已签收出现的次数
select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)  FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='已签收' 

-- 2.拒收：
select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)  FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='拒收' 

-- 3.在途：
select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)  FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='在途' 

-- 4.未发货：
select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)   FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='未发货' 

-- 5.总计：各物流反馈管道出现的次数，即已签收+拒收+在途+未发货,即总计
select `直发签收率计算表`.`物流反馈管道`,count(`直发签收率计算表`.`物流反馈管道`) as '总计'  FROM `直发签收率计算表` group by `直发签收率计算表`.`物流反馈管道`

-- 6.各渠道签收率，签收/(签收+拒收),即签收/已完成
select y.`物流反馈管道`,y.count1/(y.count1+j.count2) as '签收/已完成'
from 
(select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)as count1  FROM `直发签收率计算表`

group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='拒收') j on y.`物流反馈管道`=j.`物流反馈管道` 

-- 7.各渠道签收率，签收/(已签收+拒收+在途+未发货),即签收/总计
select y.`物流反馈管道`,y.county/z.countz as '签收/总计'
from 
(select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)as county  FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='已签收') y left join 
(select `直发签收率计算表`.`物流反馈管道`,count(`直发签收率计算表`.`物流反馈管道`) as countz FROM `直发签收率计算表` group by `直发签收率计算表`.`物流反馈管道`) z on y.`物流反馈管道` = z.`物流反馈管道`

-- 8.各渠道签收率,(签收+拒收)/总计
select y.`物流反馈管道`,(y.county+j.countj)/z.countz as '已完成/总计'
from 
(select `直发签收率计算表`.`物流反馈管道`,`直发签收率计算表`.`状态`,count(`直发签收率计算表`.`状态`)as county  FROM `直发签收率计算表` 
group by `直发签收率计算表`.`物流反馈管道` ,`直发签收率计算表`.`状态` HAVING `直发签收率计算表`.`状态`='已签收')  y left join

(select `直发签收率计算表`.`物流反馈管道`,count(`直发签收率计算表`.`物流反馈管道`) as count0 FROM `直发签收率计算表` group by `直发签收率计算表`.`物流反馈管道`) z on y.`物流反馈管道` = z.`物流反馈管道`
