Question

我有如下所示的MySQL表和示例数据

timestamp  |aggregator_id|bare_media_cost
1589868086 | 2   | 0.2
1589868086 | 2   | 0.3
1589868086 | 1   | 2.012
1589868086 | 3   | 2.3535
1589868086 | 1   | 4.343
1589868086 | 2   | 5.43434
1589868086 | 3   | 6.0101
1589954506 | 1   | 7.222

我今天早晨在运行以下查询以获取数据

 SELECT g1.aggregator_id as agid
      , round(SUM(g1.bare_media_cost/1000),2) AS "cost_one($)"
      , round(SUM(g2.bare_media_cost/1000),2) AS "cost_two($)"
   FROM TableHourly as g1 
   JOIN TableHourly as g2 
     ON g2.aggregator_id = g1.aggregator_id 
  WHERE g1.timestamp > 1589868086 
    and g2.timestamp < 1589954506 
  group 
     by agid;

我不确定这是正确的，我知道这与内部联接有关，但是获取数据花了很长时间，如果有人遗漏任何东西，有人可以突出显示，或者如果我做错了，则可以纠正

我想通过聚合器ID获取数据，以了解今天和昨天数据的成本变化

这是示例插入查询

insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 1.01);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.35);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.35);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 522, 0.798246);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.1558761169);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 544, 0.44005601);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.175);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 544, 0.02596);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 1.7378481169);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0.179);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.175);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0.024);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.115183);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0.1);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.1125);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0.111);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.218440364);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 1, 0.416);
insert into TableHourly (timestamp,aggregator_id,bare_media_cost) values (1589880600, 481, 0.1125);

 CREATE TABLE TableHourly (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
timestamp VARCHAR(30) NOT NULL,
aggregator_id VARCHAR(30) NOT NULL,
bare_media_cost VARCHAR(30) NOT NULL
)
