Unit
IB_DataPump

Declaration
TIB_DataPump = class(TIB_DataScan)

Description
This component is used to move data from a query into a prepared statement with input parameters where each input parameter is handled as a data pump item.

There are four modes of item handling:


1) Direct binding to the same point as the source fetching buffers.
2) Assigning using default type conversion.
3) Customized item handling.
4) AfterFetchRow event processing.

Use the AfterFetchRow event to finish assigning values to the input parameters that need customized attention. Be sure to NOT refer to the Dataset SrcDataset since it is NOT the actual dataset being used to feed the process. It is using an internal cursor that is passed in as a parameter the the event. You should refer to the Statement though.
