JDBC CallableStatement og Oracle SYS_REFCURSOR IN parametre?

Min java er lidt rusten, men du burde være i stand til at initialisere din REF CURSOR-variabel i en PL/SQL-blok:

String statement = "DECLARE\n" +
                       "l_cursor SYS_REFCURSOR;\n" +
                   "BEGIN\n" +
                       "your_procedure(?, l_cursor, ?);\n" +
                   "END;"
CallableStatement cs = yourConnection.prepareCall(statement);
// bind first and last parameter
cs.setString(1,"constant");
cs.registerOutParameter(2, OracleTypes.CURSOR);
