Simple question about using passing parameters in a procedure

Question

I have a below stored procedure (part of a package) that I need to modify by removing hard coded declaration of "cutoffdays" and change it into a parameter passed from procedure. I am not sure how to do declare and pass values for delete from a table.
CREATE OR REPLACE PROCEDURE  counttimes
IS
   CutOffDays   NUMBER := 14;
BEGIN  
DELETE FROM   timetable
         WHERE   timestamp_val < SYSDATE - CutOffDays;
   COMMIT;
END counttimes;

Answer 1

Hints
<li>never commit at the end of a procedure, if you didn't commit at the beginning. Do the transaction handling at a higher level.</li>
<li>Name the procedure so that it is clear what it does. If records are deleted, then the procedure name should reflect that.</li>
<li>Work with full days, i.e. use trunc(sysdate) instead of sysdate. </li>
CREATE OR REPLACE PROCEDURE  removeTimes (CutOffDays in integer)
IS
BEGIN  
       DELETE FROM   timetable
       WHERE   timestamp_val < trunc(SYSDATE) - CutOffDays;
END counttimes;Edited by: Sven W. on Feb 14, 2011 4:17 PM
