Re: oddball sorting problem

texte = To restate the problem as I think I understand it... a) You want to show all sales that have either their first or second date on or after today. This works as written. b) You want to sort by the earliest of the two dates, ignoring any date that is prior to today. This doesn't work - if the first date is prior to today, then it will sort to the top of the list. I can't think of any way to so the sorting you want within a search of the original db - there is no way to say "sort by first date then second date, but ignore the first date if it's prior to today". To get the sort you want based on your current db structure, you need to search to find the records then append the records to a table (if WebDNA 5) or a temporary DB, using one "sort date" field that holds the date (chosen by if/then/else from date1 or date2) that the sale should be sorted by. Then you need to search the table sorting on the sort date to generate the desired results. Alternatively, you could add a "sort date" field to the original DB and run a nightly trigger that puts the chosen value into that field and clears that field if the sale was in the past. This would simplify the search and sort to: [search ....gesortDatedatarq=[date]&allhit=1&sortDatesort=1&sortDatetype=date] - brian On Dec 17, 2003, at 8:56 PM, Terry Wilson wrote: > Doing a little more digging, I found allhit=1 in the online docs to > turn off relevancy, and that cleared it up, mostly. > > However, when the second date is still in the future, it is sorting on > the 1st (past) date.
