DataSourceHandle :: BeginTransaction - Start transaction for the data source
Data sources provide simple transaction control. Data source transactions cannot be nested, i.e. when a transaction is running for the data source no other transaction can be started.
Using nested transactions is possible with the DBObjectHandle .
For running very long transactions, the external transaction option should be passed as YES . External transactions provide an external storage for storing the transaction.
Return value: Success ( logical )
