Loading a Driver

Load the database driver before creating a database connection.

You can load the driver in the following ways:

Implicitly loading the driver before creating a connection in the code: Class.forName ("org.postgresql.Driver")
Transferring a parameter during the JVM startup: java -Djdbc.drivers=org.postgresql.Driver jdbctest
- jdbctest is the name of a test application.
- If gsjdbc200.jar is used, change the driver class name to "com.huawei.gauss200.jdbc.Driver".
