Derby on Intellij

Question

Я хочу установить базу данных derby на IntelliJ IDEA. Я много искал эту проблему, но я не мог найти полезный ответ. Каждый раз, когда я пытаюсь подключиться к базе данных дерби, я получаю следующую ошибку.

Может ли кто-нибудь помочь мне исправить эту проблему?

java.sql.SQLException: Failed to create database 'C:/Users/Omar/IdeaProjects/untitled3', see the next exception for details.

Предполагаю, что вы хотите создать источник данных IntelliJ.

Эти шаги:

1. Перейти к вашему Apache Derby установки бен каталог (например, компакт c:\derby\bin).
2. Start Apache Derby (например startNetworkServer)
3. Open IntelliJ Idea Project
4. Перейти на вкладку Database
5. Нажмите на иконку + для нового источника данных.
6. Выбрать Derby Remote

7. Заполните форму. Это пример того, как я сделал это:

   • Хост: Localhost
   • Порт: 1527
   • Database: демо, создать = True
   • пользователя: админ
   • Пароль: admin

URL-адрес выглядит следующим образом в моем случае:

jdbc:derby://localhost:1527/demo;create=true

Обратите внимание на использование "создания = истинного" параметра. Это важно, потому что в противном случае Derby не будет автоматически создавать вашу базу данных, и это, вероятно, является причиной вашей проблемы.

Нажмите кнопку «Применить», после чего нажмите кнопку «Проверить соединение» и все. Derby создаст вашу базу данных и подключится к ней.

База данных будет размещена в каталоге DERBY_HOME/bin, так как это место, где мы запустили сервер Derby.
