Cursor for loop gives less number of records for certain condition

Question

Hi i am getting very weired behaviour of cursor for loop.
i have one query below which returns 128 records.
select su.item_id from suv_tmp su
inner join review_items ri on su.ITEM_ID = RI.ITEM_ID
inner join sources s on s.source_id=ri.source_id
and s.source_name='XYZ'
but when i take this query in cursor for loop it returns only 100 records.
this is the cursor for loop i am writing:
begin
for v_rec in
(select su.item_id from suv_tmp su
inner join review_items ri on su.ITEM_ID = RI.ITEM_ID
inner join sources s on s.source_id=ri.source_id
where s.source_name='XYZ'
loop
dbms_output.put_line(v_rec.item_id);
end loop;
end;
It prints only 100 records.
The weired behaviour is that if i select any column name from the table which is used in where clause it gives 128 records..
query below gives expected output
begin
for v_rec in
(select su.item_id,s.source_descr from suv_tmp su
inner join review_items ri on su.ITEM_ID = RI.ITEM_ID
inner join sources s on s.source_id=ri.source_id
where s.source_name='XYZ'
loop
dbms_output.put_line(v_rec.item_id);
end loop;
end;
i am not able to find out any logc..
Any pointers appreciated..

Answer 1

1) Can you provide the DDLs of those tables and dummy data to check if it gets reproduced at our env.
2) What is the Oracle Database software version? e.g. 9iR2 , 10gR1 , 10gR2 , 11gR1 etc...
