题目:
查找入职员工时间排名倒数第三的员工所有信息,为了减轻入门难度,目前所有的数据里员工入职的日期都不是同一天
CREATE TABLE `employees` (
`emp_no` int(11) NOT NULL,
`birth_date` date NOT NULL,
`first_name` varchar(14) NOT NULL,
`last_name` varchar(16) NOT NULL,
`gender` char(1) NOT NULL,
`hire_date` date NOT NULL,
PRIMARY KEY (`emp_no`));
程序:
SELECT * FROM employees WHERE hire_date = (SELECT hire_date FROM employees ORDER BY hire_date DESC limit 2 ,1)
