Re: PHP query to mysql database returns emtpy data, butQuery Browser shows records

No the category field is varchar(250) and uses spaces to parse each element within the field. The database is an osCommerce hybrid - not my own. The values within the category field go from one number to an X set of numbers, separated by spaces. This is making development rather difficult and painful. -------Original Message------- > From: "Bastien Koert" <bastien_k@hotmail.com> > Subject: Re: [PHP-DB] PHP query to mysql database returns emtpy data, butQuery Browser shows > records > Sent: 06 Jan 2005 14:14:02 > > Perhaps an IN query clause it what he needs... > > $query example = SELECT description from cpProducts where > category IN (39, 47, 48, 172) > > bastien > > >From: Jochem Maas <jochem@iamjochem.com> > >To: graeme <graeme_foster@sherubtse.edu.bt> > >CC: Jason Walker <jwalker@desktophero.com>, php-db@lists.php.net > >Subject: Re: [PHP-DB] PHP query to mysql database returns emtpy data, > >butQuery Browser shows records > >Date: Thu, 06 Jan 2005 14:24:29 +0100 > > > >graeme wrote: > >>Hi, > >> > >>You have: > >> > >>$query example = SELECT description from cpProducts where category='39 47 > >>48 172' > >> > >>don't you want to add a logical operator such as OR, possibly AND > >> > >>$query example = SELECT description from cpProducts where category='39 OR > >>47 OR 48 OR 172' > >> > >>graeme. > > > >whatever it is that he is trying to do - I doubt he wants to put 'OR's in > >the character string, besides which AFAIK you can't do something like: > > > >SELECT description from cpProducts where category=39 OR 47 OR 48 OR 172; > > > >(possibly the SQL above will actually return all rows because any number > >greater than zero will evaluate to true - e.g. ($x = true || 1) is always > >true regardless of the value of $x, I am assuming the same general logic > >goes for SQL or'ing) > >it should be: > > > >SELECT description from cpProducts where category=39 OR 47 OR 48 OR 172; > > > >Jason, read on for more (possible) help (well I gave it a shot but I don't > >think it will be any help, sorry): > > > > > >>Jason Walker wrote: > >> > >>> > >>> > >>>Here is the query: > >>> > >>> function ReturnPackageDescriptions($pack, $cat, $hotcat, $hotid){ > >>> $comIB = $cat .
