Using todays date as default for this function in the package

Question

Dear all;
please find attached the following sample data and syntax
create table tbl_one
  id varchar2(200),
  place varchar2(300),
  create_date date
insert into tbl_one
  (id, place, create_date)
values
  ('D', 'MN', to_date('3/3/2011', 'MM/DD/YYYY'));
insert into tbl_one
  (id, place, create_date)
values
  ('X', 'DC', to_date('3/4/2011', 'MM/DD/YYYY'));
insert into tbl_one
  (id, place, create_date)
values
  ('A', 'NY', to_date('3/31/2011', 'MM/DD/YYYY'));package from PL/SQL developer
body ----------
create or replace package P_test is
  -- Public type declarations
type cur is ref cursor;
function test_fn
from_period in varchar2,
to_period in varchar2
) return cur;
end P_test;
spec ----------------------
create or replace package body P_test is
function test_fn
from_period in varchar2,
to_period in varchar2
) return cur as
my_cur cur;
Begin
  open my_cur for
  select p.id,
         p.place
  from tbl_one p
  where trunc(p.create_date) >= to_date(from_period, 'MM-DD-YYYY')
  and trunc(p.create_date) <= to_date(to_period, 'MM-DD-YYYY');
return my_cur;
end test_fn;
end P_test;now I was just wondering how do I get the to_period to have a default value of todays date

I tried that already but it doesnt work unfortunately it shows no display...the only other way i can think of is use several if statement to check and then do a select into....however i just feel there is a better way to do it.

SQL> CREATE PROCEDURE dt_test (p_start_dt IN VARCHAR2,
  2                            p_end_dt   IN VARCHAR2 DEFAULT TO_CHAR(sysdate, 'MM-DD-YYYY')) AS
  3  BEGIN
  4     DBMS_OUTPUT.Put_Line ('Start is: '||p_start_dt);
  5     DBMS_OUTPUT.Put_Line ('End is: '||p_end_dt);
  6  END;
  7  /
Procedure created.
SQL> exec dt_test('01-01-2011', '02-28-2011');
Start is: 01-01-2011
End is: 02-28-2011
PL/SQL procedure successfully completed.
SQL> exec dt_test('01-01-2011');
Start is: 01-01-2011
End is: 03-31-2011Or are you always passing two parameters with the end date possibly null like this:
SQL> exec dt_test('01-01-2011', null);
Start is: 01-01-2011
End is:
PL/SQL procedure successfully completed.If that is you case then you can do something like:
SQL> CREATE OR REPLACE PROCEDURE dt_test (p_start_dt IN VARCHAR2,
  2                                       p_end_dt   IN VARCHAR2) AS
  3  BEGIN
  4     DBMS_OUTPUT.Put_Line ('Start is: '||p_start_dt);
  5     DBMS_OUTPUT.Put_Line ('End is: '||COALESCE(p_end_dt, sysdate));
  6  END;
  7  /
Procedure created.
SQL> exec dt_test('01-01-2011', null)
Start is: 01-01-2011
End is: 31-MAR-2011
PL/SQL procedure successfully completed.So your predicate would become more like:
trunc(p.create_date) <= COALESCE(to_date(to_period, 'MM-DD-YYYY'), TRUNC(sysdate);John
