ORA-03001 funzionalità non semplificata quando si esegue Select in Java

Question

Ho provato a eseguire la seguente query Seleziona su un Oracle 11G da Java (usando il driver sottile) quando ho ricevuto quel codice di errore. La mia domanda è per questo che ottengo questo errore?Presumo che debba essere un problema con il driver sottile ma non riesco a capire cosa potrebbe essere poiché supporta le query selezionate ... Pls aiutami fuori!

java.sql.SQLException: ora-03001 unimplemented feature

Versione ORA:

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
"CORE   11.2.0.1.0  Production"
TNS for 64-bit Windows: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

.

La query era:

    query = "select e.eq_nr as \"Eqiptmentnummer\", f.file_name as \"Dateiname\" e.adress as \"Adresse\","
            + " e.city as \"Ort\", e.county as \"Bundesland\", e.zip_code as \"PLZ\","
            + " e.manufacturer as \"Hersteller\" f.doc_info as \"DOC INFO\""
            + " from elevators e join files f on(e.eq_nr = (select eq_nr from file_links where file_id = f.file_id))";

.

Utilizzo preparato ed esecuzione:

PreparedStatement ps = c.getCon().prepareStatement(query);
ResultSet rs = ps.executeQuery();

.

Ho eseguito questa query nello sviluppatore SQL e mi ha dato questa output (tutti gli ascensori e i loro file associati), che è corretto:

eq_nr | file_name     |      adress    | city  |county| zip  |manufaturer|  note

Answer 1

Potrebbe essere solo un problema di pasta di copia.In ogni query che hai pubblicato ti manca una virgola tra

f.file_name as \"Dateiname\" e.adress as \"Adresse\",

.

Ma la modifica sopra non lo è.

f.file_name as \"Dateiname\", e.adress as \"Adresse\",

.

può essere così semplice?;)

Answer 2

Assumerei che la combinazione di join / subselect non sia standard.Suggerirei qualcosa come

query = "select e.eq_nr as \"Eqiptmentnummer\", f.file_name as \"Dateiname\" e.adress as \"Adresse\","
        + " e.city as \"Ort\", e.county as \"Bundesland\", e.zip_code as \"PLZ\","
        + " e.manufacturer as \"Hersteller\" f.doc_info as \"DOC INFO\""
        + " from elevators e"
        + " join files f on (e.eq_nr = f.eq_nr)"
        + " where e.eq_nr in ("
        + "   select f.eq_nr"
        + "   from files f"
        + "   join file_links fl"
        + "   where fl.file_id = f.file_id"
        + ")";

.

Modifica

query = "select e.eq_nr as \"Eqiptmentnummer\", f.file_name as \"Dateiname\", e.adress as \"Adresse\", e.city as \"Ort\", e.county as \"Bundesland\", e.zip_code as \"PLZ\",  e.manufacturer as \"Hersteller\", f.doc_info as \"DOC INFO\""
    + " from elevators e"
    + " join file_links fl on (e.eq_id = fl.eq_id)"
    + " join files f on (f.file_id = fl.file_id)";
