Mysql统计每年每个月的数据——详细教程

Mysql统计每年每个月的数据(前端页面统计图实现)

　　　　

　　

　　　　最终想实现的效果图，在这里就不多废话了，直接上效果图，由于测试数据有几个月是为0的，所以数据图看着会有点怪怪。

　　　 另外，个人使用了ssm框架(Spring、Mybatis、SpringMVC)，可根据自己的项目情况修改

 

 

　　接下来是数据库的两个表，这里直接给你们代码了，你们根据自己的需求更改即可

 

-- 会员充值表
CREATE TABLE rechargeinfo(
    r_num INT PRIMARY KEY COMMENT '充值编号',
    v_card VARCHAR(12) COMMENT '会员卡号',
    r_recharge DOUBLE COMMENT '充值金额',
    r_payway VARCHAR(20) COMMENT '支付方式',
    o_id INT COMMENT '操作员工编号',
    r_time DATETIME COMMENT '交易时间',
    r_remark VARCHAR(50) COMMENT '交易备注',
    FOREIGN KEY (o_id) REFERENCES operatorinfo(o_id)
)ENGINE = InnoDB COMMENT '会员充值信息表';
alter table rechargeinfo change r_time r_time timestamp not null default NOW();

--停车登记表

CREATE TABLE parkinginfo(
    p_num INT PRIMARY KEY COMMENT '停车编号',
    c_carplate VARCHAR(20) NOT NULL COMMENT '车牌号',
    p_card VARCHAR(20) COMMENT '停车牌号',
    p_picture VARCHAR(50) COMMENT '进场拍摄图',
    p_entrytime Date COMMENT '进场时间',
    p_leavetime Date COMMENT '出场时间',
    p_type VARCHAR(10) COMMENT '客户类型',
    p_cost Double COMMENT '停车费用',
    p_payway VARCHAR(20) COMMENT '支付方式',
    v_card VARCHAR(12) COMMENT '会员卡号',
    v_phone VARCHAR(12) COMMENT '临时客户手机号码',
    p_condition VARCHAR(20) DEFAULT '正在停车中' COMMENT '状态',
    p_remark VARCHAR(50) COMMENT '备注'

)ENGINE = InnoDB COMMENT '停车信息表';
alter table parkinginfo change p_entrytime p_entrytime timestamp not null default NOW();

 

 

　　接下来就是重点了：

　　　　SQL语句，只需要传入一个参数（年份）即可， 这个是统计会员充值表的，另一张表同理

 

select
    sum(case month(r_time) when '1'  then r_recharge else 0 end) as Jan,
    sum(case month(r_time) when '2'  then r_recharge else 0 end) as Feb,
    sum(case month(r_time) when '3'  then r_recharge else 0 end) as Mar,
    sum(case month(r_time) when '4'  then r_recharge else 0 end) as Apr,
    sum(case month(r_time) when '5'  then r_recharge else 0 end) as May,
    sum(case month(r_time) when '6'  then r_recharge else 0 end) as June,
    sum(case month(r_time) when '7'  then r_recharge else 0 end) as July,
    sum(case month(r_time) when '8'  then r_recharge else 0 end) as Aug,
    sum(case month(r_time) when '9'  then r_recharge else 0 end) as Sept,
    sum(case month(r_time) when '10' then r_recharge  else 0 end) as Oct,
    sum(case month(r_time) when '11' then r_recharge  else 0 end) as Nov,
    sum(case month(r_time) when '12' then r_recharge  else 0 end) as Dece
from rechargeinfo
where year(r_time)='2019';

 

 

　　　效果图：可以看到，每个月的数据已经查出来了

 

　　　

　　　接下来给出的是Dao层代码，service层就不写了

import java.util.Map;

public interface TotalDao {

    Map<String,Double> getRechargeTotal(String toyear);

    Map<String,Double> getParkingTotal(String toyear);
}

　　

 

　 　　以及Mapper文件代码：注意，这里的结果类型一定要是java.util.LinkedHashMap, 如果是HashMap，是不会报错，但是顺序会乱，So，，你懂得。

<!--    统计充值-->
    <select id="getRechargeTotal" parameterType="String" resultType="java.util.LinkedHashMap">
        select
            sum(case month(r_time) when '1'  then r_recharge else 0 end) as Jan,
            sum(case month(r_time) when '2'  then r_recharge else 0 end) as Feb,
            sum(case month(r_time) when '3'  then r_recharge else 0 end) as Mar,
            sum(case month(r_time) when '4'  then r_recharge else 0 end) as Apr,
            sum(case month(r_time) when '5'  then r_recharge else 0 end) as May,
            sum(case month(r_time) when '6'  then r_recharge else 0 end) as June,
            sum(case month(r_time) when '7'  then r_recharge else 0 end) as July,
            sum(case month(r_time) when '8'  then r_recharge else 0 end) as Aug,
            sum(case month(r_time) when '9'  then r_recharge else 0 end) as Sept,
            sum(case month(r_time) when '10' then r_recharge  else 0 end) as Oct,
            sum(case month(r_time) when '11' then r_recharge  else 0 end) as Nov,
            sum(case month(r_time) when '12' then r_recharge  else 0 end) as Dece
        from rechargeinfo
        where year(r_time)=#{toyear};
    </select>

<!--统计停车-->
    <select id="getParkingTotal" parameterType="String" resultType="java.util.LinkedHashMap">
        select
            sum(case month(p_leavetime) when '1'  then p_cost else 0 end) as Jan,
            sum(case month(p_leavetime) when '2'  then p_cost else 0 end) as Feb,
            sum(case month(p_leavetime) when '3'  then p_cost else 0 end) as Mar,
            sum(case month(p_leavetime) when '4'  then p_cost else 0 end) as Apr,
            sum(case month(p_leavetime) when '5'  then p_cost else 0 end) as May,
            sum(case month(p_leavetime) when '6'  then p_cost else 0 end) as June,
            sum(case month(p_leavetime) when '7'  then p_cost else 0 end) as July,
            sum(case month(p_leavetime) when '8'  then p_cost else 0 end) as Aug,
            sum(case month(p_leavetime) when '9'  then p_cost else 0 end) as Sept,
            sum(case month(p_leavetime) when '10' then p_cost  else 0 end) as Oct,
            sum(case month(p_leavetime) when '11' then p_cost  else 0 end) as Nov,
            sum(case month(p_leavetime) when '12' then p_cost  else 0 end) as Dece
        from parkinginfo
        where year(p_leavetime)=#{toyear} and p_condition='交易完成' ;
    </select>

</mapper>

 

 

 

　　　Control层：

 

//统计页面
    @RequestMapping("/totalui")
    public ModelAndView test(@RequestParam(value ="toyear",required = false,defaultValue = "2019")String toyear){
        ModelAndView mv = new ModelAndView();
//        get all data
        Map<String, Double> rechargeTotal = service.getRechargeTotal(toyear);
        Map<String,Double> pachargeTotal = service.getParkingTotal(toyear);
//        test
        System.out.println("测试所有数据： "+rechargeTotal.values()+"  ");
        System.out.println("测试所有数据 : "+ pachargeTotal.values()+" ");

//        统计
        Map<String,Double> datatotal = new LinkedHashMap<>();
        for(String key:rechargeTotal.keySet()){
        if(pachargeTotal.containsKey(key)){
        datatotal.put(key, rechargeTotal.get(key)+pachargeTotal.get(key));
        }
       }
        System.out.println("合并后的数据！！！"+datatotal.values());

//        set atrr
        mv.addObject("redata",rechargeTotal.values());
        mv.addObject("padata",pachargeTotal.values());
        mv.addObject("totaldata",datatotal.values());
        mv.setViewName("Income");
        return mv;

    }
