数据库名称为【schoolIDB】，字符集【utf8】，排序规则【utf8_general_ci】.
1、创建数据表——DLL语句
CREATE TABLE `student` ( `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '编号', `ceateDate` datetime DEFAULT NULL COMMENT '创建时间', `userName` varchar(20) COLLATE utf8_icelandic_ci DEFAULT NULL COMMENT '姓名', `pwd` varchar(36) COLLATE utf8_icelandic_ci DEFAULT NULL COMMENT '密码', `phone` varchar(11) COLLATE utf8_icelandic_ci DEFAULT NULL COMMENT '手机号', `age` tinyint(3) DEFAULT NULL COMMENT '年龄', `sex` char(2) COLLATE utf8_icelandic_ci DEFAULT NULL COMMENT '性别', `introduce` varchar(255) COLLATE utf8_icelandic_ci DEFAULT NULL COMMENT '简介', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8 COLLATE=utf8_icelandic_ci;
2、插入数据——DML语句
insert into student values (0,'2022-02-02 10:10:10','葫芦娃爷爷','123123','1234567690',69,
'男','葫芦娃爷爷，在穿山甲的帮助下找到了葫芦籽');
insert into student values (0,'2022-02-02 10:10:10','蛇精','123123','1234566890',66,
'女','那个坏女人，绑架了葫芦娃');
insert into student values (0,'2022-02-02 10:10:10','蜈蚣精','123123','1234567860',67,
'男','那个坏男人，绑架了葫芦娃们');
insert into student values (0,'2022-02-02 10:10:10','一娃','123123','1634567890',23,
'男','金刚娃');
insert into student values (0,'2022-02-02 10:10:10','二娃','123123','1236567890',26,
'男','水娃');
insert into student values (0,'2022-02-02 10:10:10','三娃','123123','1234567896',24,
'男','拿个破葫芦');
insert into student (userName,age,introduce) VALUES('山神',25,'孕育了葫芦娃兄弟')
select * from student
3、编辑语句——DQL
SELECT userName as '用户名',age 年龄,sex'性 别',introduce'简介' from student where pwd is not 123123; SELECT distinct sex '性别类型' from student; SELECT * from student order by userName desc; SELECT * from student limit 5,3;
