I imagine that it is without the point, if it is with the point I would have to find out what you are talking about.

executeQuery() as the name itself says, it is for queries, it almost always uses a SELECT in it and a result will be returned with the data, or an error.

executeUpdate() as its name says, it is for updates, you should use a written command like INSERT , UPDATE and DELETE , and it returns what has been affected and not a result of data.
