Executing procedure for period

Question

Hi all,
My need is to execute procedure with parameter date for period from 01.03.2011 till 31.03.2011.
One way is to type dates one per line:
EXEC schemename.pkg_name.procedure_name date '2011-03-01';
EXEC schemename.pkg_name.procedure_name date '2011-03-02';
EXEC schemename.pkg_name.procedure_name date '2011-03-30';
EXEC schemename.pkg_name.procedure_name date '2011-03-31';But how do I execute it using more simple code?

Hello
It kind of depends what you mean by simpler. If you want to avoid having 31 separate calls to the procedure listed on 31 lines, you can use a loop like so...
SQL> DECLARE
  2
  3      ldt_StartDate       DATE := TO_DATE('01/03/2011','dd/mm/yyyy');
  4      ldt_EndDate         DATE := TO_DATE('31/03/2011','dd/mm/yyyy');
  5
  6  BEGIN
  7
  8      FOR lc_Dates IN (   SELECT
  9                              ldt_StartDate + (rownum -1) dt
10                          FROM
11                              dual
12                          CONNECT BY
13                              LEVEL <= CEIL(ldt_EndDate - ldt_StartDate) + 1
14                      )
15      LOOP
16          dbms_output.put_line(lc_Dates.dt);
17      END LOOP;
18
19  END;
20  /
