Specifies an SACommand object that is executed against the database when the Update method is called to delete rows in the database that correspond to deleted rows in the DataSet.
If this property is not set and primary key information is present in the DataSet during Update, DeleteCommand can be generated automatically by setting SelectCommand and using the SACommandBuilder. In that case, the SACommandBuilder generates any additional commands that you do not set. This generation logic requires key column information to be present in the SelectCommand.
When DeleteCommand is assigned to an existing SACommand object, the SACommand object is not cloned. The DeleteCommand maintains a reference to the existing SACommand.
