在SQL*PLUS中如何创建oracle表

简单例子：
create table t_name1 (id int,name varchar2(20));
alter table t_name1 add constraits pk_t_name1 primary key(id);

详细语法讲解可以参考这里：

表student:
create table student(
stuno number(4) not null,
stuname varchar(20) not null,
stubatch varchar(20) not null)
加约束:
alter table student
add constraits stu_stuno_pk primary key(stuno);
