oracle - tricky plsql procedure to delete data -


friends , pl/sql gurus...

i trying create procedure delete data audit table don't know start with..

it great if provide tips or pointer...

requirements:

  1. procedure run on first saturday of month (not sure possible via pl/sql or have create separate job)

  2. delete data older 2 months mon - sat , date shouldn't 1st of month. (i.e. leave sunday & 1st of month data older 2 months)

e.g.

*procedure delete_log   begin   delete audit_logs created >= trunc(sysdate - 60) , created < trunc(sysdate) , created != (sunday) , created != (first of month);  commit;  end delete_log;*

i don't have experience pl/sql tips appreciated..

thanks, mike

to schedule job can use cron job @ server level or oracle scheduler run tasks http://docs.oracle.com/cd/b28359_01/server.111/b28310/scheduse002.htm#i1006395

something work:

create or replace procedure delete_log begin    delete audit_logs              trunc (created) < add_months (trunc (sysdate), -2)                , to_char (trunc (created), 'dy') != 'sun'                , to_char (trunc (created), 'dd') != '01'; end; /
