Redirecting Dynamic URL To Static

I have cms whose blogpost looks like

www.example.com/2009/08/06/example.html

Code (markup):

and they are configured in .htaccess for following request

Now somehow google has indexed the dynamic version of URL that looks like

www.example.com/?subaction=showfull&year=2009&month=08&day=06&news_name=example

Code (markup):

Now i want to redirect that long URL to the previous one i.e.

www.example.com/2009/08/06/example.html

Code (markup):

This is because to prevent google to see same content in both URL'S as i stated google has indexed the dynamic one but my URL Structure/Sitemap Uses the static one and i can't change it.

Any help will be appreciated!

 

Use a 301 redirect (google 301 redirect). Also, I would suggest using robots.txt to tell google not to index dynamic pages.
