SQL hat mehrere Sätze als Ergebnis, in der IFS-Zieldatei landet aber nur einer.

Hallo Dieter,

würde das in Java so aussehen oder liege ich hier falsch. Statt dem Microsoft Access Driver müsste man hier den DB/2 JDBC-Driver einsetzen.

    doc.appendChild(results);

    ResultSet rs = con.createStatement().executeQuery("select * from product");

    ResultSetMetaData rsmd = rs.getMetaData();
    int colCount = rsmd.getColumnCount();

      Element row = doc.createElement("Row");
      results.appendChild(row);
      for (int i = 1; i <= colCount; i++) {
        String columnName = rsmd.getColumnName(i);

    System.out.println(sw.toString());

    rs.close();
  }
