modulo elenco/menu

[NiKolino]

Ciao a tutti,

sto facendo un sito dinamico in ASP, utilizzando Dreamweaver.
Ho inserito un modulo "Elenco/Menù" nella quale vengono visualizzati i dati inseriti all'interno di un database.

Dreamweaver mi ha creato questo codice(immobili è il nome del database e contratto è il nome della colonna dalla quale vengono estratti i dati):

<select name="contratto" id="contratto">
<%
while (!Immobili.EOF) {
%>
<option value="<%=(Immobili.Fields.Item("Contratto").Value )%>"><%=(Immobili.Fields.Item("Contratto").Value)% ></option>
<%
Immobili.MoveNext();
}
if (Immobili.CursorType > 0) {
if (!Immobili.BOF) Immobili.MoveFirst();
} else {
Immobili.Requery();
}
%>
</select>

Dal momento che i dati nella colonna contartto sono solo 2 e vengono ripetuti più volte, come faccio a fare in modo che il mio elenco non mi ripeta questi dati, ma li visualizzi soltanto una volta?

Dreamweaver non è in grado di fare una SELECT DISTINCT in SQL?

[NiKolino]

Quindi dovrei andare a modificare il codice a mano?

Come?

Come? A mano.
Vediamo sta pagina per intero?

[NiKolino]

Vuoi vedere tutto il codice della pagina?

Immobili.Source = "SELECT DISTINCT(Contratto) AS Contratto FROM [tabelli immobili] GROUP BY Contratto";

[NiKolino]

Ho inserito il codice che mi hai fornito al posto di questo:

Immobili.Source = "SELECT * FROM [tabelli immobili]";

Ma non funziona. Quando provo mi dice che è impossibile visualizzare la pagina.

Immobili.Source = "SELECT DISTINCT(Contratto) FROM [tabelli immobili] GROUP BY Contratto";
