Quickstart

Embedding H2 in an Application

This database can be used in embedded mode, or in server mode. To use it in embedded mode, you need to:

• Add the h2*.jar to the classpath (H2 does not have any dependencies)
• Use the JDBC driver class: org.h2.Driver
• The database URL jdbc:h2:~/test opens the database test in your user home directory
• A new database is automatically created

The H2 Console Application

The Console lets you access a SQL database using a browser interface.
