How can I get just one row from selected column?

Hi.
How can I get just one row from selected column and put it into html
dropdown list
I tried like this:

function pobierz_wszystko($tabela,$kolumna)
{
$zapytanie="SELECT $kolumna FROM $tabela";
$wynik=mysql_query($zapytanie);
while($wiersz=mysql_fetch_array($wynik,MYSQL_ASSOC))
{
echo "$wiersz
";
}
}


All
pobierz_wszystko('hotel','hotel_nazwa');
?>



But it doesn't work properly because I'm getting a dropdown list with
All,and Array,Array,Array,Array,Array
Instead of Array I'd like to have a value from a row.

Is it because I'm using mysql_fetch_array($wynik,MYSQL_ASSOC)?
or maybe the query is wrong?

Thanks
