MySql常用操作SQL语句汇总

MySQL的常见操作在这里先做一下总结，已经整合到代码里面，经过检验无误。
复制代码代码如下:
/*创建一个数据库*/
create database xuning_test;
/*说明当时使用数据库对象*/
use xuning_test;
/*向数据库中添加表并且定义表的结构*/
create table person（
id int not null,
name varchar（16） not null,
sex varchar（16） not null,
age int not null,
address varchar（128） not null,
remark varchar（512） not null
）;
/*向数据库的表中插入数据*/
insert into person value
（1,"name_1","men",99,"beijing","This is a frindsheep boy"）,
（2,"name_2","men",88,"shanghai","ok great"）,
（1,"name_3","man",77,"guangzhou","This is lickly"）,
（1,"name_4","men",66,"beijing","This is a frindsheep boy"）,
（1,"name_5","men",55,"beijing","you dont going to shool"）,
（1,"name_6","man",44,"beijing","This is a frindsheep boy"）,
（1,"name_7","men",33,"beijing","This is a frindsheep boy"）,
（1,"name_8","man",22,"beijing",""）,
（1,"name_9","men",11,"beijing","This is a frindsheep boy"）
;
/*查询时否成功插入*/
select * from person;
/*下面是多种查询方式*/
/*根据列的名称属性值*/
select name from person;
/*添加条件-根据性别*/
select name from person where sex = "men";
/*也可以用比较符作为条件--一定逗号隔开*/
select name,address from person where age > 50;
/*看做对象去使用数据库和表的关系=---双表关联--对象关系一定要明确*/
select xuning_test.person.name, xuning_test.person.id, xuning_test.person.age, xuning_test.person.address
from xuning_test.person, test1.test_xuning
where xuning_test.person.id = test1.test_xuning.id
;
/*使用表的别名进行查询*/
use xuning_test;
select c.name,sex from person as c where c.age > 40 and c.address="beijing";
