1、数据表中增加一个字段:insert into tblStudent (a,b,c,...) values(1,2,3,...);
2、将.sql语句加入到本地数据库:source /home/homework/user/zxy/mysql/tblStudent.sql;
3、创建数据库:create database homework_discuss;
4、根据关键字查询信息:select * from tblStudent where student_uid=123123\G;
5、按照学生uid降序查询10个学生信息:select * from tblStudent order by student_uid desc limit 3\G;
6、更新指定学生的年级信息:update tblStudent set grade=7 where student_uid=123123;
7、显示数据库的创建语句:show create table tblStudent;
8、查看时间戳对应时间:select from_unixtime(1465704144);
