- parameterObject
- RelationalCommandParameterObject
Parameters for this method.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation. The task result contains the result of the command.
Exceptions
If the CancellationToken is canceled.
