（数据库-MySQL）表-数据插入

插入数据，有3种格式：

insert into 表名(列名1,列名2)values(值1,值2);

insert into 表名 values(值1,值2);

批量插入:insert into 表名values(值1,值2),(值1,值2),(值1,值2);

例如：

insert into student(stuid,stuname,gender,stutel) values(1,'zhangsan',1,1511111111);

insert into student(stuid,stuname,gender,stutel) values(2,'lisu',2,1511111112);

select *from student;

如果不使用列名，需要把每列的值都进行插入，否则会报错；而且每列对应的类型和格式必须符合表创建时的类型与约束条件！

insert into student values(3,'zhangsan',1,1511111113,NULL,'2009-07-19',NULL);
insert into student values(4,'zhangsan',1,1511111113,'123@qq.com','2009-07-19','CalssNine');

批量插入：

insert into student values(5,'zhangsan',1,1511111113,'123@qq.com','2009-07-19','CalssNine'),(6,'zhangsan',1,1511111116,'123@qq.com','2009-07-19','CalssNine'),(7,'zhangsan',1,1511111117,'123@qq.com','2009-07-19','CalssNine'),(8,'zhangsan',1,1511111118,'123@qq.com','2009-07-19','CalssNine');

插入时候，一定要注意数据类型和格式，字符串一定要加引号！
