sql语句如下:
create table p( id int primary key)type =innode;
create table c( id int primary key, pid int , foreign key(pid) references p(id) on update cascade on delete cascade)type =innode;
create table c( id int primary key, pid int , foreign key(pid) references p(id) on update cascade on delete cascade)type =innode;
一个问题:所有的关键字必须用大写吗?
