H2 Connector

This node creates a connection to a H2 database file via its JDBC driver. You need to provide the path to the database file or the name when using in-memory mode. No username and password are required for H2 databases.

This node uses the selected driver's JDBC URL template to create the concrete database URL. Field validation in the dialog depends on whether the (included) tokens referencing them are mandatory or optional in the template.
