Mysql統計每年每個月的數據——詳細教程

Mysql統計每年每個月的數據(前端頁面統計圖實現)

　　　　

　　

　　　　最終想實現的效果圖，在這里就不多廢話了，直接上效果圖，由於測試數據有幾個月是為0的，所以數據圖看着會有點怪怪。

　　　 另外，個人使用了ssm框架(Spring、Mybatis、SpringMVC)，可根據自己的項目情況修改

 

 

　　接下來是數據庫的兩個表，這里直接給你們代碼了，你們根據自己的需求更改即可

 

-- 會員充值表
CREATE TABLE rechargeinfo(
    r_num INT PRIMARY KEY COMMENT '充值編號',
    v_card VARCHAR(12) COMMENT '會員卡號',
    r_recharge DOUBLE COMMENT '充值金額',
    r_payway VARCHAR(20) COMMENT '支付方式',
    o_id INT COMMENT '操作員工編號',
    r_time DATETIME COMMENT '交易時間',
    r_remark VARCHAR(50) COMMENT '交易備注',
    FOREIGN KEY (o_id) REFERENCES operatorinfo(o_id)
)ENGINE = InnoDB COMMENT '會員充值信息表';
alter table rechargeinfo change r_time r_time timestamp not null default NOW();

--停車登記表

CREATE TABLE parkinginfo(
    p_num INT PRIMARY KEY COMMENT '停車編號',
    c_carplate VARCHAR(20) NOT NULL COMMENT '車牌號',
    p_card VARCHAR(20) COMMENT '停車牌號',
    p_picture VARCHAR(50) COMMENT '進場拍攝圖',
    p_entrytime Date COMMENT '進場時間',
    p_leavetime Date COMMENT '出場時間',
    p_type VARCHAR(10) COMMENT '客戶類型',
    p_cost Double COMMENT '停車費用',
    p_payway VARCHAR(20) COMMENT '支付方式',
    v_card VARCHAR(12) COMMENT '會員卡號',
    v_phone VARCHAR(12) COMMENT '臨時客戶手機號碼',
    p_condition VARCHAR(20) DEFAULT '正在停車中' COMMENT '狀態',
    p_remark VARCHAR(50) COMMENT '備注'

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

 

 

　　接下來就是重點了：

　　　　SQL語句，只需要傳入一個參數（年份）即可， 這個是統計會員充值表的，另一張表同理

 

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';

 

 

　　　效果圖：可以看到，每個月的數據已經查出來了

 

　　　

　　　接下來給出的是Dao層代碼，service層就不寫了

import java.util.Map;

public interface TotalDao {

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

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

　　

 

　 　　以及Mapper文件代碼：注意，這里的結果類型一定要是java.util.LinkedHashMap, 如果是HashMap，是不會報錯，但是順序會亂，So，，你懂得。

<!--    統計充值-->
    <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>

<!--統計停車-->
    <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層：

 

//統計頁面
    @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("測試所有數據： "+rechargeTotal.values()+"  ");
        System.out.println("測試所有數據 : "+ pachargeTotal.values()+" ");

//        統計
        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("合並后的數據！！！"+datatotal.values());

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

    }

 

　　　　前端頁面顯示圖代碼：
