Sys_refcursor not fetching any data although query returns value

Question

hi!!!
I am using sys_refcursor to return columns,and using below procedure to do so.Although data is there in table_1 and table_2.
PROCEDURE test_pro(abc_date N DATE,
cur_get_data OUT sys_refcursor
OPEN cur_get_data
for
select A.col1,B.col2
from table_1 A
where A.dis_date=abc_date
left outer join
table_2 B
on
A.dis_date=B.dis_date;
IF cur_get_data%rowcount=0
then
     raise e_error;
END if;
EXCEPTION
     when e_error
     then
          ------no_data_found;
     when others
     then
--------(giving SQL error with error code);
END      test_pro;
while running below sql in sql window of pl/sql developer fetching
data
select A.col1,B.col2
from table_1 A
where A.dis_date=abc_date
left outer join
table_2 B
on
A.dis_date=B.dis_date;
but while testing the test_pro in test window of pl/sql developer it is
not fetching any data and raising e_error each time
is there any problem arising using IF cur_get_data%rowcount=0 as each time it is going to exception block..
so can somebody please put some ideas what cud be the possible reason for this??

A cursor doesn't fetch data - your code has to do that. The code you posted doesn't have any FETCH statements so no data will be fetched.
There is no problem using 'IF cur_get_data%rowcount=0' but it will always be 0 in your code because you are not fetching any data.
I'm guessing that you are trying to determine if there are any rows for the query. That isn't going to work since a cursor doesn't fetch rows.
You just have to return the cursor to the caller and the caller will have to perform at least one fetch to see if there are any rows.
If the above answers your question the just mark the question ANSWERED. Otherwise, since you have posted in the wrong forum
1. repost the question in the SQL and PL/SQL forum
2. Edit this post to add a link to the new thread in the other forum
3. Mark this question ANSWERED so people will follow up in the other forum.
Thanks.
