Apache Derby

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in JetBrains Rider by default. If the relevant features are not available, make sure that you did not disable the plugin.

1. Press to open settings and then select Plugins.

2. Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.

• For full information about Apache Derby, refer to the official documentation.

• To download Apache Derby database software, refer to the official software downloads.

To connect to a database, create a data source that will store your connection details.

1. In the Database tool window, click New and select Connect to Database.

2. If you have a connection string for the database defined in your solution or elsewhere, leave the Use connection string option selected and choose Apache Derby in the Database type selector.

   Use the String selector to choose the desired connection string from your solution or type it in manually, then click Connect.

3. You can also choose Add data source manually, click Next and select Apache Derby in the Database source selector. Follow the wizard steps to form the connection string by configuring individual options.

4. To access all available options for the new database connection, click in the Database window, then click New and select Apache Derby.

5. In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type.

   1. From the Driver list, select the JDBC driver for your connection.

      For Apache Derby, the supported drivers are Apache Derby (Embedded) and Apache Derby (Remote). For more information about Apache Derby databases, refer to the official documentation: embedded databases, remote databases.

   2. From the Connection type list, select the connection type depending on the connection details that you have:

      Connection types for Apache Derby (Embedded)

      • Embedded: connect by using the path to the database folder.

      • In-Memory: connect to a temporary database stored entirely in the main memory.

      • URL only: connect by using only the URL.

      Connection types for Apache Derby (Remote)

      • default: connect by using Host, Port, Database, and URL.

      • URL only: connect by using only the URL.

      For the URL only connection type, the JDBC URL that you enter is used and as is, including the database credentials.

      note

      For the URL only connection type, the JDBC URL is stored in plain text as is, and is also available in IDE log file and data source information.

      For the other connection types, the JDBC URL is broken down into connection details. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.

   

6. Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page.

   

   Location for the downloaded JDBC drivers is the JetBrains Rider configuration directory.

   You can also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection.

   If there is no Download missing driver files link, then you already have the required drivers.

7. Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.

      • Format: jdbc:derby:<path_to_the_file_or_folder>

      • Example: jdbc:derby:myDatabase

      For more information about the URL format, refer to the Apache Derby official documentation.
