insert//insert into插入数据

insert into users(id,name,gender,birthday,address,telephone) values (1,"高某","男","1981-11-05","北京","15809320031");
insert into users(name,gender,birthday,address,telephone) values ("罗某","女","1984-01-15","北京","15800310933");
insert into users(name,gender,birthday,address,telephone) values ("张某","女","1994-05-01","北京","15899432158");

update//更新一个或多个字段

update users set address="甘肃",telephone="17103318972" where id=4;

alter//添加、删除或修改字段

like//LIKE 子句与等号 = 的效果是一样的,SQL LIKE 子句中使用百分号 %字符来表示任意字符。

select * from users where telephone like "158%";
