类 Driver

java.lang.Object

org.h2.Driver

所有已实现的接口:

Driver, JdbcDriverBackwardsCompat

public class Driver
extends Object
implements Driver, JdbcDriverBackwardsCompat

The database driver. An application should not use this class directly. The only thing the application needs to do is load the driver. This can be done using Class.forName. To load the driver and open a database connection, use the following code:

 Class.forName("org.h2.Driver");
 Connection conn = DriverManager.getConnection(
      "jdbc:h2:˜/test", "sa", "sa");
