DISTRICT and LIKE problem. HELP

[Max Jakub]

Hi i have this Table filled with 5 rows:
numer, cena, opis, zdjecia, dzial.

I have a small searching tool, to show only information user want's to see.
BUT, i have few records, with same data, only with other 'dzial' data.
I want to show only 1 of them.
I tried to use DISTRICT, but it seems to not work.

Here's php code:

$query = "SELECT DISTRICT (numer), cena, opis, zdjecia FROM oferty WHERE
cena LIKE '%$phrase%' OR
opis LIKE '%$phrase%' OR
numer LIKE '%$phrase%'";

PLEASE HELP!
