SQL to display all days between two dates

Oracle Database Tips by Donald BurlesonNovember 23, 2015

Question:  How do I write a SQL to display the number of months between two dates?
 
Answer:  Here is a simple way to display the dates between two dates:

BEWARE:  Using the trunc function will invalidate the index on order_date, and you may want to create a temporary function-based index on trunc(order_date)

select
   order_nbr
from
  sales_order

where
   trunc(ORDER_DATE) between
     to_date('03-01-2016','MM-DD-YYYY')
   and
     to_date('03-11-2016','MM-DD-YYYY');

Here is a way to display the dates between two dates in PL/SQL:

set serveroutput on size 1000000
declare
start_date date := to_date('01-JAN-2016','DD-MON-YYYY');
end_date   date := to_date('05-JAN-2016','DD-MON-YYYY');
Begin
loop
   start_date := start_date +1;
   if start_date < end_date then
      dbms_output.put_line(start_date);
   else
      exit;
   end if;
end loop;
exit;
/

Here is yet another way to get the dates between two dates:

select
   to_date('03-01-2015','dd-mon-yyyy') + rownum -1

from
   all_objects

where
   rownum <=

   to_date('01-01-2016','dd-mon-yyyy')-to_date('03-01-2015','dd-mon-yyyy')+1;

And another way to get dates between two dates:

select
   to_date('04-01-2016','dd-mm-yyyy') + lvl

from
   (select level - 1 lvl

    from
      dual
    connect by
   level <= (to_date('10-01-2015','dd-mm-yyyy') - to_date('04-01-2016','dd-mm-yyyy'))+ 1);

And yet another way to get the dates between two dates:

select * from
   (select
      rno||'-'||to_char(:p_start_date,'MON-YYYY') date_val
    from(
      select
         rownum
         from

         (
           select 1 from dual
           group by cube(0,0,0,0,0,0)
         )
      where
   rownum < to_char(last_day(:p_start_Date),'DD')))
where date_val between :p_start_date and :p_end_date;
