Occurs when putting loading data by rows is needed.
property OnPutData: TDAPutDataEvent;
Write the OnPutData event handler to put loading data by rows.
Note that rows should be loaded from the first in the ascending order.
To start loading, call the Load method. It is more effective way to load data in comparison with using OnGetColumnData. The OnPutData event handler must send column data by the TDALoader.PutColumnData method. TDALoader will flush data to Oracle when it is needed.
