Database query to search using address

Question

I am developing a search functionality to search for dealers by their address(i.e. by postcode(zip) or by name or by city)for my project. user will be provided with only one htm

In MySQL you do it like this:

     "SELECT `zip`, `name`, `city` FROM `dealers` WHERE `zip` = '$zip' ORDER BY `zip` DESC"
     "SELECT `zip`, `name`, `city` FROM `dealers` WHERE `name` = '$name' ORDER BY `name`"
     "SELECT `zip`, `name`, `city` FROM `dealers` WHERE `city` = '$city' ORDER BY `city`"

I don't use Oracle but I think that it is the same. (This code assumes that zip is a varchar, if it is an integer value just remove the ' ')
