Hi everyone,
I have a function returning set of date called datelist(date,date)
example:
select * from datelist('8/1/2005, 8/5/2005');
8/1/2005
8/2/3005
8/3/2004
8/4/2005
8/5/2005
I would like to join this function with a table
create table payment(
id int4 not null,
date_start date,
date_end

select * from payment P, datelist(P.date_start

try select * from payment as p, (select * from datelist('8/1/2005, 8/5/2005')) as date
where date.. = p.
try select * from payment as p, (select * from datelist('8/1/2005, 8/5/2005')) as datewhere date.. = p.
The problem is the function's parameters '8/1/2005', '8/5/2005' has torefer to whatever value on the payment records.

what about something likeselect id,datelistfrom payment as p,(select * from datelist('8/1/2005, 8/5/2005')) as list
where datelist between p.date_start and p.date_end;
That's works but have to put the whole date range into the parameters before it can be joined.
This would need 2 queries where
