The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.

OK... Decided to post regardless of the answer to whether 6 days is a hard value.
If it is, the following works, without recursion.
Unfortunately I cannot currently performance test this.
update orders set ship_date =
select day6.dt from
calndr day1, calndr day2, calndr day3
, calndr day4, calndr day5, calndr day6
where day1.dt=(select min(dt) from dates where dt>order_date
and flag='Y')
and day2.dt=(select min(dt) from dates where dt>day1.dt
and flag='Y')
and day3.dt=(select min(dt) from dates where dt>day2.dt
and flag='Y')
and day4.dt=(select min(dt) from dates where dt>day3.dt
and flag='Y')
and day5.dt=(select min(dt) from dates where dt>day4.dt
and flag='Y')
and day6.dt=(select min(dt) from dates where dt>day5.dt
and flag='Y')
Never say, "never."
