篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了数据分析画图,使用原生sql查询数据相关的知识，希望对你有一定的参考价值。
1、使用工具
https://www.hcharts.cn/
http://echarts.baidu.com/
2、子表查询
id 创建时间 内容 处理者
1 2017-02-01 11:11 1
2 2017-03-01 11:11 11
3 2017-04-01 11:11 2
4 2017-05-01 11:11 1
5 2017-02-02 11:11 1
1. 思路
处理者列表 = select 处理着 from tb
for 处理者 in 处理者列表:
v = select * from tb where 处理者=处理者 group by 创建时间(2017-02)
2. 思路
# 每个月份全部门处理的订单个数
select * from tb group by 创建时间(%Y-%m)
select
创建时间(%Y-%m),
(select count(id) from tb as T2 where 处理者=1 and T2.ctime = T1.ctime ),
(select count(id) from tb as T2 where 处理者=2 and T2.ctime = T1.ctime ),
from tb as T1 group by 创建时间(%Y-%m)
年月 id=1 id=2
2017-02 2
2017-03 0
2017-04 0
2017-05 1
