sql查询如何筛选奇偶数

例: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
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`));

 

答案:

select * from employees
where emp_no % 2 = 1
and last_name != 'Mary'
order by hire_date desc
