void __fastcall Release();
Releases all the dataset cursors.
The Release method call releases all the dataset cursors, but does not close it. After this call no more cursors are accessible. As a result, the dataset will not fetch any more records from the cursor and SourceEOF will be True.
If ResourceOptions.AutoFetchAll is True, then before releasing the cursors, the dataset fetches all the remaining records from the current cursor. If it is False and not all records are fetched, then an exception is raised. The application can explicitly fetch all the dataset records by calling the FetchAll method.
