Hello Subbarao, I am not sure, I understand what you want to achieve.
I suppose you are using the JdbcSchema (directly or indirectly), most likely through the JDBC Adapter. If that's the case then probably the reason that you don't see the user-defined functions is that the getFunctions() method is not yet implemented.
