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;

declare

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

begin

end_term := '200601';

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

end;

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;

declare
   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;

begin
   end_term := '200601';

   for v_row in c1 loop
      dbms_output.put_line(v_row.term);
   end loop;
end;

When I execute your query, I get the following error:

ERROR at line 14:
ORA-06550: line 14, column 30:
PLS-00302: component 'TERM' must be declared
ORA-06550: line 14, column 3:
PL/SQL: Statement ignored
