Mysql统计每年每个月的数据——详细教程
Winton-Q 人气:0Mysql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。
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
1 -- 会员充值表 2 CREATE TABLE rechargeinfo( 3 r_num INT PRIMARY KEY COMMENT '充值编号', 4 v_card VARCHAR(12) COMMENT '会员卡号', 5 r_recharge DOUBLE COMMENT '充值金额', 6 r_payway VARCHAR(20) COMMENT '支付方式', 7 o_id INT COMMENT '操作员工编号', 8 r_time DATETIME COMMENT '交易时间', 9 r_remark VARCHAR(50) COMMENT '交易备注', 10 FOREIGN KEY (o_id) REFERENCES operatorinfo(o_id) 11 )ENGINE = InnoDB COMMENT '会员充值信息表'; 12 alter table rechargeinfo change r_time r_time timestamp not null default NOW(); 13 14 --停车登记表 15 16 CREATE TABLE parkinginfo( 17 p_num INT PRIMARY KEY COMMENT '停车编号', 18 c_carplate VARCHAR(20) NOT NULL COMMENT '车牌号', 19 p_card VARCHAR(20) COMMENT '停车牌号', 20 p_picture VARCHAR(50) COMMENT '进场拍摄图', 21 p_entrytime Date COMMENT '进场时间', 22 p_leavetime Date COMMENT '出场时间', 23 p_type VARCHAR(10) COMMENT '客户类型', 24 p_cost Double COMMENT '停车费用', 25 p_payway VARCHAR(20) COMMENT '支付方式', 26 v_card VARCHAR(12) COMMENT '会员卡号', 27 v_phone VARCHAR(12) COMMENT '临时客户手机号码', 28 p_condition VARCHAR(20) DEFAULT '正在停车中' COMMENT '状态', 29 p_remark VARCHAR(50) COMMENT '备注' 30 31 )ENGINE = InnoDB COMMENT '停车信息表'; 32 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
1 select 2 sum(case month(r_time) when '1' then r_recharge else 0 end) as Jan, 3 sum(case month(r_time) when '2' then r_recharge else 0 end) as Feb, 4 sum(case month(r_time) when '3' then r_recharge else 0 end) as Mar, 5 sum(case month(r_time) when '4' then r_recharge else 0 end) as Apr, 6 sum(case month(r_time) when '5' then r_recharge else 0 end) as May, 7 sum(case month(r_time) when '6' then r_recharge else 0 end) as June, 8 sum(case month(r_time) when '7' then r_recharge else 0 end) as July, 9 sum(case month(r_time) when '8' then r_recharge else 0 end) as Aug, 10 sum(case month(r_time) when '9' then r_recharge else 0 end) as Sept, 11 sum(case month(r_time) when '10' then r_recharge else 0 end) as Oct, 12 sum(case month(r_time) when '11' then r_recharge else 0 end) as Nov, 13 sum(case month(r_time) when '12' then r_recharge else 0 end) as Dece 14 from rechargeinfo 15 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，是个程序员，dao层知道，service都会写
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>
</mapper>
Control层：
1 //统计页面
2 @RequestMapping("/totalui")
3 public ModelAndView test(@RequestParam(value ="toyear",required = false,defaultValue = "2019")String toyear){
4 ModelAndView mv = new ModelAndView();
5 // get all data
6 Map<String, Double> rechargeTotal = service.getRechargeTotal(toyear);
7 Map<String,Double> pachargeTotal = service.getParkingTotal(toyear);
8 // test
9 System.out.println("测试所有数据： "+rechargeTotal.values()+" ");
10 System.out.println("测试所有数据 : "+ pachargeTotal.values()+" ");
11
12 // 统计
13 Map<String,Double> datatotal = new LinkedHashMap<>();
14 for(String key:rechargeTotal.keySet()){
15 if(pachargeTotal.containsKey(key)){
16 datatotal.put(key, rechargeTotal.get(key)+pachargeTotal.get(key));
17 }
18 }
19 System.out.println("合并后的数据！！！"+datatotal.values());
20
21 // set atrr
22 mv.addObject("redata",rechargeTotal.values());
23 mv.addObject("padata",pachargeTotal.values());
24 mv.addObject("totaldata",datatotal.values());
25 mv.setViewName("Income");
26 return mv;

28 }
