Description

Use the DataSet property to specify the source or the destination dataset.

You can use a dataset of any class descendend from TDataSet. TFDBatchMoveDataSetDriver offers additional features for the following dataset classes:

TFDAdaptedDataSet is the base class for most FireDAC datasets, including TFDQuery, TFDTable, TFDStoredProc, TFDMemTable. TFDBatchMove for these datasets:
- supports TFDBatchMove.AbortJob method;
- offers improved support for auto-incremental fields;
- setups dataset for optimal reading / writing speed when TFDBatchMoveDataSetDriver.Optimise is True;
- creates a destination DB table for TFDTable when poCreateDest is included into TFDBatchMove.Options;
- supports direct write operations when TFDBatchMoveDataSetWriter.Direct is True.
TFDMemTable:
- at the beginning of the data moving a writer creates the in-memory table if it is not active;
- at the end of the data moving a writer leaves in-memory table open.
classes supporting IProviderSupportNG interface:
- support transaction control;
- support obtaining of list of indexes;
- support obtaining the source DB table name.
