Oracle SYS_REFCURSOR couldn't use as a return type

Question

I need to extract and display all the years for all the records in db using member function in oracle 11g.

CREATE or replace TYPE BODY student_t AS 
MEMBER FUNCT         


        

Answer 1

I'm not sure what you are trying to achieve but I think you misunderstood concept of object in oracle. In my example i'm assuming
1) Table studens is create with this script create table student of student_t;

drop table student;

Create type spec and body.

create or replace type student_t as object(
stno char(4),
dob date,
member function getYear return number

)
;

create or replace type body student_t as

    member function getYear return number is 
    begin 
            return  EXTRACT(YEAR FROM self.dob);
    end;

end;

Create table of studnets

create table student of student_t;

Populate tabel

declare 
  v_student student_t;
begin 
for i in 0 .. 10 loop 
  insert into student values(student_t('ST'||+mod(i,3),to_date('01-01-'||to_char(2000+i),'dd-mm-yyyy')));
end loop;
commit;
end; 

And the query.

select s.*,s.getYear() from student s;
