描述
有一个员工表employees简况如下:
请你查找employees表所有emp_no为奇数，且last_name不为Mary的员工信息，并按照hire_date逆序排列，以上例子查询结果如下:
示例1
drop table if exists `employees` ;
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`));
INSERT INTO employees VALUES(10001,'1953-09-02','Georgi','Facello','M','1986-06-26');
INSERT INTO employees VALUES(10002,'1964-06-02','Bezalel','Simmel','F','1985-11-21');
INSERT INTO employees VALUES(10003,'1959-12-03','Bezalel','Mary','M','1986-08-28');
INSERT INTO employees VALUES(10004,'1954-05-01','Chirstian','Koblick','M','1986-12-01');
INSERT INTO employees VALUES(10005,'1953-11-07','Mary','Sluis','F','1990-01-22');
输出
10005|1953-11-07|Mary|Sluis|F|1990-01-22
10001|1953-09-02|Georgi|Facello|M|1986-06-26
我的答案
select * from employees where emp_no % 2 = 1 and last_name != 'Mary' order by hire_date desc;
