ora-03001 unimplemented feature when running select in java

Question

i tried to run following select query on an oracle 11g from java (using thin driver) when i got that error code back. my question is why i get this error? i assume it must be an issue with the thin driver but i cant figure out what it could be since it does support select querys... pls help me out !

java.sql.SQLException: ora-03001 unimplemented feature

ora version:

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

the query was:

    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))";

using preparedStatement and executeQuery:

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

i ran this query in sql developer and it gave me this output(all elevators and their associated files), which is correct:

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

Answer 1

It might be just a copy paste issue. In every query you posted you are missing a comma between

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

but the edit above does not.

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

Can it be that simple? ;)

Answer 2

I would assume the join/subselect combination is not standard. I would suggest something like

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"
        + ")";

EDIT

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)";
