语句:
comment on table 表名 is \'表的注释信息\'; comment on column 表名.字段名 is \'字段的注释信息\';
注意表名的大小写
例如:
1、创建表:
CREATE TABLE Student(
id varchar2(32) primary key,
name varchar2(8) not null,
age number
);
2、添加表注释:
Comment on table Student is \'个人信息\';
修改表注释:
Comment on table Student is \'学生个人信息\';
3、添加字段注释:
comment on column Student.id is \'id\';
comment on column Student.name is \'姓名\';
comment on column Student.age is \'年龄\';
修改字段注释:
comment on column Student.id is \'学生id\';
comment on column Student.name is \'学生姓名\';
comment on column Student.age is \'学生年龄\';
