如何在MYSQL中找到点酒量最多的饮酒者？

Question

到目前为止，我已经能够找到每个饮酒者在一天内的饮酒量。

SELECT DRINKER, ODATE, COUNT(DRINK) TOTAL
FROM ORDERS 
GROUP BY ODATE, DRINKER
ORDER BY TOTAL DESC, DRINKER ASC;

然后，我需要在样本数据库中插入一个饮酒者的两个新订单的信息，这个饮酒者在一天内订购了最多的酒量。这里是我不知道具体该怎么做的地方。这是我目前的尝试。

INSERT INTO ORDERS VALUES(SELECT DRINKER, ODATE, COUNT(DRINK) TOTAL
FROM ORDERS 
GROUP BY ODATE, DRINKER
ORDER BY TOTAL DESC, DRINKER ASC);

我对MYSQL很陌生 所以我非常感激任何帮助！

下面是CREATE和INSERT语句。

Answer 1

我不太明白你的问题，但我认为你需要一个触发器来插入这些数据。

SELECT DRINKER, ODATE, COUNT TOTAL.
FROM ORDERS 
GROUP BY ODATE, DRINKER
ORDER BY TOTAL DESC, DRINKER ASC;

在另一张表中插入这些数据 我给你提供了这个触发器，但在此之前，所有创建一个表，例如测试收集数据。

这是测试表。

DROP TABLE IF EXISTS "test";
CREATE TABLE IF NOT EXISTS `test` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `drinker` varchar(50) NOT NULL,
  `odate` date NOT NULL,
  `total` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

这是触发器

DROP TRIGGER IF EXISTS "test";
DELIMIT $$
CREATE TRIGGER `test` AFTER INSERT ON `orders` FOR EACH ROW BEGIN
    INSERT into test (drinker, odate, total)
    SELECT DRINKER, ODATE, COUNT(DRINK) TOTAL FROM ORDERS;
END
$$
DELIMIT;

不知道对你有没有帮助，但我也开始了，关于触发器的更多信息，我给你这个链接。https:/sql.shcourscreate-trigger(触发器)
