    TO 'jdbc:mysql://192.168.99.100:3306/my_database' 
    USER 'user_name'
    IDENTIFIED BY 'my_password';

To test the connection, run the following statement.

Copy 
select * from 
(
import from JDBC at JDBC_MYSQL
statement 'select ''Connection works'' from dual'
);

Load data

Use IMPORT to load data from a table or SQL statement using the connection that you created.
