Fixed Date Columns

Question

Hi Everyone,
Does anyone know how to create a formula that will generate finxed date columns for a certain period of time. I'd like to put a range of two dataes (l3 months) and have the formula generate a column for each day, even though I may not have any records for certain days.
Thanks,
Romeo

If I understand correctly (an example would be nice...), you'll need to generate the data for your columns in an SQL Command, something like (MS SQL):
declare @day datetime;
set @day = {?Start Date}
create table #days (day datetime);
while @day <= {?End Date}
begin
  insert into #days (@day)
  set @day = dateadd(d, 1, @day)
end;
select *
from #days d
left join table t
on d.day = t.data_date
(Or, if you have a calendar table already, you can use that, obviously.)
HTH,
Carl
