如何在 MYSQL 中找到点了最多饮料的饮酒者？答案

【问题标题】：How to find the drinker who ordered most amount of drinks in MYSQL?如何在 MYSQL 中找到点了最多饮料的饮酒者？
【发布时间】：2020-06-10 13:19:00
【问题描述】：

到目前为止，我已经能够找到每位饮酒者一天内的饮料量。

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

然后，我需要向示例数据库中插入有关一天内订购最多饮料的饮酒者的两个新订单的信息。这是我不确定该怎么做的地方。到目前为止，这是我的尝试：

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 非常陌生，因此将不胜感激任何帮助！

这里是 CREATE 和 INSERT 语句：

    CONSTRAINT DRINKNAME_PKEY PRIMARY KEY(DRINK) );

CREATE TABLE DRINKERS ( /* All drinkers */
DRINKER VARCHAR(30) NOT NULL,
    CONSTRAINT DRINKERS_PKEY PRIMARY KEY (DRINKER));

CREATE TABLE LOCATED(   /* Pubs have locations */

    CONSTRAINT LOCATED_PKEY PRIMARY KEY(PUB) );

CREATE TABLE SERVES(    /* Pubs serve drinks */

@Strawberry 你有什么对我的问题有用的信息吗？

标签： mysql sql select sql-insert

【解决方案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;

在另一张桌子上。我建议您使用此触发器，但在所有创建表之前，例如测试以收集数据：

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;

这里是触发器

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;

我不知道这是否会帮助你，但我也开始了，有关触发器的更多信息，我给你这个链接： https://sql.sh/cours/create-trigger
