If you are not using foreign key constraints , you could do two statements on a single command:

DELETE FROM ChildTable; DELETE FROM ParentTable;

But in effect that is two statements.

Or

You could put a trigger on the ChildTable that deletes parent records on deletion of child record.

I think it will help you. If you are trying any query, post query.
