SQL & PL/SQL

Hello Experts

I’m trying to write a procedure in which I’m taking PROVINCE as an input parameter. All the provinces are stores in a table. I’m using a cursor and rowtype variable to check the province. After I finds province I displays province and its code. Everything works fine expect when I don’t find the province. I’m not sure how to exit from loop if I don’t find the province. I already uses exit when condition. I was expecting else condition should work and should exit from the loop but it doesn’t. Can please somebody show me how to exit if I don’t find province in the table through cursor.

Here is my code

set serveroutput on
variable G_TAX varchar2(10)
CREATE OR REPLACE PROCEDURE p_create(i_state VARCHAR2)is
CURSOR cur_bb_tax is
select * from bb_tax;
bb_tax_details bb_tax%rowtype;
begin
if not cur_bb_tax%isopen then
open cur_bb_tax;
end if;
loop
fetch cur_bb_tax into bb_tax_details;
if (bb_tax_details.state = i_state) then
dbms_output.put_line(bb_tax_details.state || bb_tax_details.idstate);
end if;
exit when bb_tax_details.state = i_state;
end loop;
close cur_bb_tax;

exception
when others then
dbms_output.put_line(SQLERRM);
end;

Thanks in advance
