2022-11-27：超过经理收入的员工。编写一个 SQL 查询来查找收入比经理高的员工。以下数据的结果输出是 Joe，因为 Joe 是唯一挣得比经理多的雇员。 DROP TABLE IF EXISTS `em

DROP TABLE IF EXISTS `employee`;CREATE TABLE `employee` (  `id` int(11) NOT NULL,  `name` varchar(255) NOT NULL,  `salary` int(11) NOT NULL,  `manager_id` int(11) DEFAULT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1;
INSERT INTO `employee` VALUES ('1', 'Joe', '70000', '3');INSERT INTO `employee` VALUES ('2', 'Henry', '80000', '4');INSERT INTO `employee` VALUES ('3', 'Sam', '60000', null);INSERT INTO `employee` VALUES ('4', 'Max', '90000', null);

SELECT     a.NAME AS employeeFROM employee AS a JOIN employee AS b     ON a.manager_id = b.id     AND a.salary > b.salary
