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".
