Get next record from Fast/Unload (FastUnloadTask class)
This callable
method requests the next record from the Fast/Unload task method object,
and it returns the new state of that FastUnloadTask object as a FastUnloadTaskState enumeration value.
Syntax
[%fastUnloadTaskState =] fastUnloadTask:GetNextRecord
Syntax terms
| %fastUnloadTaskState | A declared enumeration object of type FastUnloadTaskState to contain the state of fastUnloadTask after GetNextRecord retrieves the record from fastUnloadTask. |
|---|---|
| fastUnloadTask | An instantiated FastUnloadTask object variable. |
Usage notes
- GetNextRecord can only be called when fastUnloadTask is in the Started or HaveRecord state. If called in the Done state, the request is cancelled.
