Remarks
This delegate is called when an asynchronous method call made to a DataAsyncCommand object has completed execution.
The result is always equal to the return value for the equivalent synchronous method, as follows:
The AsyncPrepare method returns a String object
The AsyncDeriveParameters method returns a DataParameter object.
The AsyncDeriveSchema method returns a DataReader object.
The AsyncExecutemethod returns a DataReader object.
The AsyncExecuteWithoutResults method returns a Int32 object.
