Exact fetch return more than requested number of rows

I have the following PL/SQL code which I am trying to test by copying and pasting it next to the SQL prompt. I want to obtain all the distinct termcodes from three years up to the value in end_term.

set serveroutput on size 9999999999999999;


end_term varchar2(8);
term varchar2(8);


end_term := '200601';

select distinct termcode into term from student where termcode between to_char(to_number(end_term)-300) and end_term;


However, I obtain the following error:

ERROR at line 1:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at line 10

How do I fix it?

You need to use a cursor to return multiple rows:

set serveroutput on size 9999999999999999;

   end_term varchar2(8);
   term varchar2(8);
   cursor c1 is
          select distinct termcode
          from student
          where termcode between to_char(to_number(end_term)-300) and end_term;

   end_term := '200601';

   for v_row in c1 loop
   end loop;
