Query displays no output when run from sqlplus and from procedure its displ

Question

Hi Guys,
When i ran the below query, it gives me "no rows selected". I made a procedure for the below query by making it a cursor. I just tried to display the total number of records in the procedure. When ran, it showed me some number. I dont understand , why when ran just as a sql query didnt showed any output and when ran as a procedure showing some output.
select cust_account_id
,related_cust_account_id
,object_version_number
,ship_to_flag
,status
from apps.HZ_CUST_ACCT_RELATE re
where
nvl(re.bill_to_flag,'N') ='N'
and re.customer_reciprocal_flag = 'Y'
and re.status = 'A';
declare
cursor c1 is the above query
v_count number;
begin
for rec in c1 loop
v_count := v_count + 1;
end loop;
dbms_output.put_line(' V-Count is:' || v_count);
end;
also tried to print the values of the select when count is 10, it showed some values. But why is it not showing any values when ran just as a sql query.
Help Appreciated
Thanks

Thanks Warren n Dmytro,
Actually, the problem is that table has 1769645 rows of data. I wrote a cursor as defined above in a procedure. With that where condition, it doesnt have any values and so displays no rows. Its taking 5 min to run that query and get me the output.
In the begin, I want to open that cursor using "for rec in c loop" and write one more select statement which is:
begin
for rec in c loop
begin
select count(*) into l_count
from hz_cust_acct_relate_all
where cust_account_id = rec.cust_account_id
and related_cust_account_id = rec.related_cust_account_id;
exception
when others then
dbms_output.put_line(-265676,"SOme err msg");
end;
if l_count = 0 then
now my question is, if my cursor is not returning any rows, then the query written to get l_count will be executed or not. I am passing the cursors cust_account_id and related_cust_account_id values to this query. but that cursor is returning no data.
so what will happen to the code that i wrote. Will it hang or will it continue. Or should i write when no_data_found exception to handle when no rows are returned.
or can in include " exit when c%notfound after for loop". when we use open fetch and close, then we will write this exit when. can we write when using for rec in c loop syntax.
coz when i run that procedure, it jsut hangs like that forever. how to handle it or how to tune it.
help appreciated
thanks
