30 Business Days Back

409782Aug 13 2010 — edited Aug 15 2010

Hi All,

I need to find the calendar date 30 business days back from SYSDATE:

Formula: Calendar Date = SYSDATE - "30 business days"

I have a table contains:

cal_dt,bus_day,holiday
.
.
.
7/1/10,1,NULL
7/2/10,1,NULL
7/3/10,0,NULL
7/4/10,0,NULL
7/5/10,0,'Y'
7/6/10,1,NULL
.
.
.

For the life of me, I can't figure it out how to write the SQL? Please help.

Using Oracle 10g.

Thanks,
Mary
