Hibernate Query for multiple tables

[sudhakar Tadepalli]

Hi,
I ran my test cases with a direct table which deals with one table one mapping file one pojo.

If I want to get data from multiple tables for a given identifier do I have to create pojo with attributes quried from multiple tables ?.
Can I right a straight SQL and execute using Hibernate for this scenario?

If a table have association with another table will querying parent table automatically retrieves child table data and returns its pojos ?

Can some one explain me. Thank in advance.
