Sender jdbc adapter

   I have 1 query which is related to my requirement.

My scenario is     JDbc---->PI------->Jdbc .Here i want fetch data from database through the sender jdbc and insert values in receive jdbc.

Here my doubt was i want to fetch the data from more than a table and those tables not having any relationship(Primary key and  foreign key and rows data are separated ).then how can i call in single statement?

Querying two tables without any relation?

Thanks
