例:查找employees表所有emp_no為奇數,且last_name不為Mary的員工信息,並按照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
