H2

In the Database tool window ( View | Tool Windows | Database), click the Data Source Properties icon .

On the Data Sources tab in the Data Sources and Drivers dialog, click the Add icon () and select H2.

Check if there is a Download missing driver files link at the bottom of the data source settings area. As you click this link, AppCode downloads drivers that are required to interact with a database. The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.

You can specify your drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.

From the Connection type list, select the connection mode: Remote, In-memory, Embedded. For more information about these modes, see the official H2 documentation.

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

To delete a password, right-click the Password field and select Set Empty.

To ensure that the connection to the data source is successful, click the Test Connection link.

(Optional) If you are connecting to a data source that contains a lot of databases and schemas, in the Schemas tab, select the schemas that you need to work with.

Click OK to create the data source.
