But the problem with this logic and Mark's post is what about holidays? =
If
holidays also have to be accounted for as well as weekend days then you =
need
either a work calendar table to join to or a not in subquery on a list =
of
holidays.  Being hard coding value lists is bad practice so I would go =
with
a holiday calendar table.  Still if this is just an exercise you have

Glen,
if today is Friday the 24 and 2 weeks (10 biz days ago) is mon the
13th,
you need to find records that have last_change_date <=3D3D the 13th?
I think this'll do it...
=3D20
select *
from your_table
where last_change_date <=3D3D (=3D20
select sysdate-(count(*)+1)
from (
select rownum days
from your_table
where rownum <=3D3D sysdate - (sysdate-14)
)
where to_number(to_char(sysdate+days,'d')) not in (1,7)
)                     =3D20

- a

Yes I do have the last change date.

I have problems determining 10 business days in a query.  I can't go =
=3D3D
back 2 weeks because it may contain a weekend.

The version of  oracle is 9.2.0

which version of Oracle? or do you have a table column containing a =
=3D3D
last change date? you don't provide enough information to answer your
question ...

Kind regards,
Lex.

How can I create a query that determine a rows that has not been =3D3D
updated for the last 10 business days.  That would be the last 2 weeks
not =3D3D including the weekend.
