RazorSQL JDBC Bridge Interface Method There are two options when using the RazorSQL JDBC Bridge to access databases, Interface and Driver. If using the Interface method, connections to the database are obtained by calling a method on a Java class that returns a database connection. The Service Interface Method is the name of the method to call on the Java class to get the connection. The method should be a no-argument method and return a Connection object. For more information, see the RazorSQL JDBC Bridge User's Guide in the help documentation.
