Изменение свойств DataSource в RunTime

[AndyD]

По-моему я совсем потерялся. На всякий случай приведу код, может поможет

PHP код:

public void executeQuery()
{
    Query                   q = new Query();
    QueryBuildDataSource    qbCustTable, qbCustTrans;

    if (SwitchButton.selection() == 0)
    {
        qbCustTable = q.addDataSource(tablenum(CustTable));
        qbCustTable.addSortField(fieldnum(CustTable, CustGroup));
        qbCustTable.orderMode(OrderMode::GroupBy);
        qbCustTable.addSelectionField(fieldnum(CustTable, RecId), SelectionField::Max);
        qbCustTable.addSelectionField(fieldnum(CustTable, CustGroup));

        qbCustTrans = qbCustTable.addDataSource(tablenum(CustTrans));
        qbCustTrans.clearLinks();
        qbCustTrans.joinMode(JoinMode::InnerJoin);
        qbCustTrans.addLink(fieldnum(CustTable, accountNum), fieldnum(CustTrans, accountNum));
        qbCustTrans.addSortField(fieldnum(CustTrans, TransDate));
        qbCustTrans.orderMode(OrderMode::GroupBy);
        qbCustTrans.addSelectionField(fieldnum(CustTrans, AmountCur), SelectionField::Sum);
        qbCustTrans.addSelectionField(fieldnum(CustTrans, TransDate));

    }
    else
    {                         
        qbCustTrans = q.addDataSource(tablenum(CustTrans));
        qbCustTrans.addSortField(fieldnum(CustTrans, TransDate));
        qbCustTrans.orderMode(OrderMode::GroupBy);
        qbCustTrans.addSelectionField(fieldnum(CustTrans, AmountCur), SelectionField::Sum);
        qbCustTrans.addSelectionField(fieldnum(CustTrans, TransDate));

        qbCustTable = qbCustTrans.addDataSource(tablenum(CustTable));
        qbCustTable.clearLinks();
        qbCustTable.joinMode(JoinMode::InnerJoin);
        qbCustTable.addLink(fieldnum(CustTable, accountNum), fieldnum(CustTrans, accountNum));
        qbCustTable.addSortField(fieldnum(CustTable, CustGroup));
        qbCustTable.orderMode(OrderMode::GroupBy);
        qbCustTable.addSelectionField(fieldnum(CustTable, RecId), SelectionField::Max);
        qbCustTable.addSelectionField(fieldnum(CustTable, CustGroup));
    }
    CustTable_ds.Query(q);
    super();
}
