In MySQL, how do I batch rename tables within a database?

joomla1.5, mysql

Solution

SELECT  concat ('rename table ',table_name,' to ',table_name,'_old;')
FROM information_schema.tables
WHERE table_name like 'webform%'
  and table_schema='weiss_db_new'

will work.

Problem

So basically I have a joomla database in MySQL which has a bunch of tables that have the prefix 'jmla_'. I would like to rename all of these tables by replacing the 'jmla_' prefix with a 'jos_' prefix. Any ideas about how to do this with a simple SQL script or SQL query?
