Subj:		Re: History table monthend logic

Bruce,

I am not very clear on your requirement but a variation of the following SQL could work.

select acct_num,plan_code,plan_start_date,plan_end_dt
from plan_history
where plan_beg_dt <= '31-NOV-2002'  and
      plan_end_dt <= '31-NOV-2002'     /* this will give history before
NOV-31
      or pplan_end_dt = '9999-12-31'
                  /* this should give the transaction opened before
NOV-30 and still current */
qualify csum(1,acct_num,plan_code,plan_start_dt desc, plan_end_dt desc )
= group by acct_num,plan_code
/* If you want only the latest you would use a OLAP function to qualify
the latest */

Thanks
