create view emp_v as select * from employees where emp_no >10005;
如何获取emp_v和employees有相同的数据？
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`));
(你能不用 select * from employees where emp_no >10005完成吗，挑战一下自己对视图的理解吧)
输出格式:| emp_no | birth_date | first_name | last_name | gender | hire_date |
