Remarks
If there is nothing to cancel, nothing occurs. However, if there is a command in process, and the cancellation try fails, no exception is generated.
To cancel a query on one thread, Cancel must be called from another thread. Because you cannot execute commands asynchronously with OdbcCommand, to cancel a command from another thread, one thread must be running synchronously. This means that the OdbcCommand object must be accessible from both threads.
