Comparing two records from different tables error.

Question

Hi folks!
I have this PL/SQL Block.
I want to compare the only one record from both tables to see if the content of them are equal or not, but I don't want to specified column by column to do that.
Any idea?
Thanks a lot in advanced,

Satyaki De,
Java is involving because an Outsourcing new project. The outsourcing company is developing the new application using JSF which invoke an interface java method [depending of the operation: select, update, insert] and them invoke the PLSQL API to precess tha operation.
In the case I already wrote here, the issue is this:
The user search for a specific data using the interface. The java method send a request for these operation through the API. the PLSQL process the request and return a beam, with all the column the user look for.
The user see the information in the application windows. Assuming the user wants to change some data, he modify just one field [lets say telephone number] and press the update button. The application process the request using a different method, which invoke a different function within the PLSQL API.
Once the information is returning to the API, I must know if at least one field change its value. So I was thinking to get the beam with the data before it was changed and compare it with the beam with the changing data.
If current_beam = new_beam
then
update
else
no change to process
end if;
Any idea.
