phpmyadmin - Find and Replace text in the entire table using a MySQL query

Question

Usually I use manual find to replace text in a MySQL database using phpmyadmin. I'm tired of it now, how can I run a query to find and replace a text with new text in the entire table in phpmyadmin?

Example: find keyword domain.com, replace with www.domain.com.

If you want to edit from all tables, best way is to take the dump and then find/replace and upload it back.
