我创建了一个 person 类型的对象,我想创建一个名为 student typ 的子类型,但是当我尝试使用以下脚本在脚本文件中执行此操作时出现错误:
CREATE TYPE person_typ AS OBJECT(
first_name VARCHAR2(30),
last_name VARCHAR2(30),
dob DATE,
telephone_Number VARCHAR2(20),
mobile_Number VARCHAR2(15),
address_Line1 VARCHAR2(25),
address_Line2 VARCHAR2(25),
city VARCHAR2(30),
town VARCHAR2(30),
postcode VARCHAR2(8))
NOT FINAL;
CREATE TYPE student_typ UNDER person_typ(
student_Number VARCHAR2(20),
student_Email VARCHAR2(30))
;
显示的错误是:
Error at line 13: PLS-00103: Encountered the symbol "CREATE" 0.03 seconds
