[thelist] Issues working with dates

[Ken Schaefer]

ORDER BY <yourDateTimeField>

is all you need assuming:
a) it is a DateTime field (check this again!)
b) the dates/times are being entered properly. If you are using Classic ASP then you have no strong variable typing, so I'd ensure you format them as yyyy-mm-dd when supplying parameters to your ADO Command object, to ensure there is no ambiguity when sending them to SQL Server.

Cheers
Ken

Hi Joel -

The dates are stored in a MS SQL database.  The dev server is running MS SQL
2000 and the production server was just upgraded to 2008 (big difference,
huh?)  :)

They are stored in a datetime field.  I was simply doing an "order by
endDate", but I guess that's probably not the best way to do it?

what specific problem are you having?

if you'll never use the time, yeah, just use the date

if you need one date field for "when it was added" and another for
"shelf life, sell by date" or whatever, yeah, two fields, if they're not
linked by some calculable number

are your dates in a database, I'm assuming? which one? how is it storing
the dates, as a datetime field, or as strings? how are you doing the
comparison or sorting?
