mysql related question

Hi. Im very new in this list right now, but I need help! :-) I am dealing with a mysql database and I would like to get some information from a single field. I do it with mysql_fetch_array($sql); so I think I will get an array from this. Now what I need is to remove any possible duplicate values from this array. I tried to do it width array_unique(); but I get an error smth about wrong data type :-( Has anyone dealt with this kind of a problem or can someone let me know how can I remove duplicate values from an SQl result? thanks in advance, with best regards ___________________ Erki Kukk erki@kukk.com
