Característica no implementada ORA-03001 cuando se ejecuta Seleccionar en Java

Question

Intenté ejecutar la siguiente consulta seleccionada en un Oracle 11g de Java (usando el controlador delgado) cuando recibí ese código de error. Mi pregunta es por eso que recibo este error?Supongo que debe ser un problema con el conductor delgado, pero no puedo averiguar qué podría ser, ya que es compatible con las consultas seleccionadas ... ¡Por favor, ayúdame!

java.sql.SQLException: ora-03001 unimplemented feature

Versión 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 consulta fue:

    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))";

Uso de articulación preparada y ejecutores:

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

Corrí esta consulta en SQL Developer y me dio esta salida (todos los ascensores y sus archivos asociados), que es correcta:

Answer 1

Podría ser solo un problema de pasta de copia.En cada consulta que le publicó, le faltan una coma entre

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

Pero la edición anterior no.

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

¿Puede ser tan simple?;)

Answer 2

Asumiría que la combinación de unión / subselección no es estándar.Yo sugeriría algo como

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"
        + ")";

editar

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)";
