Hello Sivakumar,
If you really want a no code solution then you should download a trial of qRules here http://www.qdabra.com/en/products/qRules_new.aspx
You can use qRules' SetCase command. It returns a string with the value of the source node in the case requested. Options are Lower, Upper and Title.
Let me know if you encounter problem when trying it out and I'll help you out.
