In Java Aufruf Prozedur oder Funktion in Oracle PL/SQL. Zurück Resultset falsch

Question

ich eine Funktion plsql haben, führen Sie Funktion in plsql Rückkehr Cursor haben Daten aber ich nenne diese Funktion in Java-Problem Rückkehr Cursor leer mir Hilfe Problem Umgang mit diesem

Das ist Funktion Orakel plsql

diese

ist Code java Aufruf Funktion

ArrayList arr = new ArrayList(); 
      sql = "begin ? := config_pkg.get_canh_bao(?,?,?,?); end;"; 
      cs = conn.prepareCall(sql); 
      cs.registerOutParameter(1, OracleTypes.CURSOR); 
      cs.setString(2, ""); 
      cs.setString(3, "502"); 
      cs.setString(4, ""); 
      cs.setString(5, ""); 
      cs.executeQuery(); 
      ResultSet rs = (ResultSet)cs.getObject(1); 
      System.out.println("------------Exception---------------"+rs.next()); 
      while (rs.next()) { 

       System.out.println("a"); 
       String[] str = 
       {"1" }; 
       arr.add(str); 
      }

Sie bind-Variablen verwenden sollten, wäre ähnlich wie diese:

pwhere := ''; 
s := 'select b.TYPE_REPORT, b.DAY_NHAPLIEU, a.sql_cmd, a.name_createdate' 
    ||' from cpcdata.tbl_config_nhaplieu a' 
    ||' left join cpcdata.tbl_mainmenu b' 
    ||' on a.tool_id = b.ID ' 
    ||' where b.show_all = 0 and b.flag = 1 and b.ID = :toolId'; 
execute immediate s INTO ptype, pday, psql, pcreate USING toolId; 
     -- Tinh ngay canh bao 
     if (INSTR(psql,'where') > 0) then 
      pwhere := ' and '; 
     else 
      pwhere := ' where '; 
     end if; 
     s := psql ||pwhere||pcreate||' between :aDate AND :bDate'; 

     CASE 
      WHEN ptype = 'day' THEN ... 
      WHEN ptype = 'week' THEN 
       open re for s USING TRUNC (sysdate, 'iw'), TRUNC(sysdate, 'iw') + 7 - 1/86400- pday; 
      WHEN ptype = 'month' THEN ... 
     END CASE;
