For example, to connect the user tom with password secret to the database webdb on the server dbserver, use the following URL: Derby JDBC database connection URL for network client driverHere is the syntax of Derby JDBC database connection URL for the network client driver: jdbc:derby://server/ databaseName*The default port is 1527 if omitted.

Connect to a database called webdb inside a jar file db.jar which is not on the classpath:Ĥ.

Connect to a database called webdb inside a jar file which is on the classpath:.

Where the absolute directory E:/projects/codejava is added to the classpath.

Connect to a database presents in the classpath:.

Jdbc:derby:memory:codejava/webdb create=true

Connect and create a database if not exist in the memory:.

Jdbc:derby:E:/projects/codejava/webdb create=true

Connect to a database in the file system using absolute path:.

The database path is relative to the system directory.

Connect and create a database called webdb under the directory codejava.

password=: specifies password of the username to connect.

user=: specifies the username to connect.

create=true: creates the database if it does not exist.

attribute= value: specifies one or more additional attributes when making the connection.

jar: looks for the database inside a jar or zip file.In this way the database is treated as in read-only mode. classpath: looks for the database in the file system which is relative to the classpath directory.This may e useful in case we only use a temporary database. memory: looks for the database in memory.This is the default location if subsubprotocol is not specified. For the relative path, Derby will look in the system directory (specified by the environment variable user.dir). The directory can be relative path or absolute path. directory: looks for the database in the file system.Where subsubprotocol tells where Derby should look for the database.Derby JDBC database connection URL for embedded driverFollowing is the syntax of Derby JDBC database connection URL for the embedded driver: jdbc:derby:*

The driver manager can load appropriate driver based on the database connection URL. Or if the JDBC client connects to Derby server on a remote machine, go with the network client driver.If you are using Java 5.0 or earlier, you have to load the driver explicitly like this: Class.forName(".EmbeddedDriver") Or: DriverManager.registerDriver(new .EmbeddedDriver()) However, since Java 6.0 or later, loading JDBC driver as such becomes optional. So if you are planning to use everything of Derby in one machine, go with the embedded driver.
