Because as I see it you used executeUpdate(), which is for doing INSERT,
UPDATE, DELETE directly. You are actually running function that hides
the UPDATE and returns a void resultset, which executeUpdate() does not
know what to do with. As was mentioned upstream try using executeQuery()
instead.

Because JDBC is meant to be used against many database engines and is
meant to be fairly generic?
