AXAPTA - Execute direct SQL statement

The sample given at that  blog worked for me good. Unfortunately in sample at this blog and others always read just one field from query. I got an error about index when try to read fields more than one. Later I learned I have to read fields in ascending numeric order from a Microsoft's  page . Run method from server side. In the other case you wold be get a security error. For insert ve delete (however this's not an advicable way for Axapta tables) instead of executeQuery you can use executeUpdate.

public server static InventRep FillSQL(DatePhysical _DatePhysical = today())
{
    InventRep   InventRep;

    Connection      connection;
    Statement       statement;
    str             query,dateStr;
    Resultset       resultSet;

    ;

    dateStr = date2str(_DatePhysical,321,dateday::Digits2,dateseparator::None,
    datemonth::Digits2,dateseparator::None,dateyear::Digits4);

    connection = new Connection();
    statement = connection.createStatement();
    query =
        "select ITEMID,SUM(QTY)"+
        "from INVENTTRANS "+
        "where DATAAREAID='TST'"+
        "and DATEPHYSICAL <='"+dateStr+"' "+
        "group by ITEMID "+
        "having SUM(QTY) <>0";
     new SqlStatementExecutePermission(query).assert();
     resultSet = statement.executeQuery(query);
     while(resultSet.next())
     {
        //---- fields shoud be in numeric order ------
        InventRep.ItemId = resultSet.getString(1);
        InventRep.Qty    = resultSet.getReal(2);
        InventRep.insert();
     }
     CodeAccessPermission::revertAssert();
}
