An AseCommand that is executed against the database when Update() is called to update rows in the database that correspond to updated rows in the DataSet.
When UpdateCommand is assigned to a previously created AseCommand, the AseCommand is not cloned. The UpdateCommand maintains a reference to the previously created AseCommand object.
If execution of this command returns rows, these rows can be merged with the DataSet depending on how you set the UpdatedRowSource property of the AseCommand object.
