建立一个主外键关系
create table t_dept(
id int(4) not null, name varchar(50) not null,
primary key(id))type=innodb;
create table t_emp (
id int(6) not null,
name char(255) not null,fk_id int(4) not null,
primary key(id),
foreign key (fk_id) references t_dept (id)) type=innodb; ......

好了,下面我们开始:
先创建两个表:一个是innodb引擎的,一个是myisam引擎的
CREATE TABLE `innodb` ( `id` in ......
Linux下mysql的安装步骤（非rpm安装）
1 下载mysql-standard-5.0.27-linux-i686-glibc23.tar.gz 包
2 解压到安装目录： tar -zxvf /edass/db/mysql-standard-5.0.27-linux-i686-glibc23.tar.gz
3 将 mysql-standard-5.0.27-linux-i686-glibc23链接到mysql : ln –s mysql-standard-5.0.27-linux-i686 ......
1 导出:
进入命令行: 执行
mysqldump -u username -p password –all-databases > all.sql
详细参数:
