--創建類型說明***********************************************************

create or replace type dept_type as object(

--成員變量

h_deptno number(2),

h_dname varchar2(14),

h_loc varchar2(13),

--成員函數、過程

member procedure changedept(name in varchar2,loc in varchar2),

member function getdeptno return number,

member function gedtname return varchar2,

member function getloc return varchar2);

--類型創建完成

--創建類型包體

create or replace type body dept_type as

member procedure changedept(name in varchar2,loc in varchar2) is

begin

h_dname := name;

h_loc := loc;

end changedept;

member function getdeptno return number as

begin

return h_deptno;

end getdeptno;

member function gedtname return varchar2 as

begin

return h_dname;

end gedtname;

member function getloc return varchar2 as

begin

return h_loc;

end getloc;

end;

--包體創建完畢-----------------------

--使用類型

declare

dept1 dept_type;

begin

dept1 := dept_type(10,'chenchaoyang','chenchaoyang');

dept1.changedept('supan','supan');

dbms_output.put_line(dept1.getdeptno);

dbms_output.put_line(dept1.getloc);

end;

--調用完畢*******************************************************
