Любая идея? Спасибо.

Просьба указать установку ddl. – Hannes

Может быть, это потому, что вы называете 'ps.executeQuery();' дважды?

Это имело бы смысл. Их программа будет пытаться вставить запись во второй раз, что приведет к нарушению ограничения первичного ключа. Я собирался спросить о схеме, а затем увидел ваш ответ. –

Большое спасибо за указание на опечатку. : D – user2461116
