Some database queries that you might want to use and bookmark in your database administration tool such as MySQL Query Browser. http://dev.mysql.com/downloads/gui-tools/5.0.html or SQLyog http://www.webyog.com/en/index.php

Here is a query that will show you the pages in your wiki that contain a particular string. In this example, I wanted to find all pages that were using the 'Icon' extension parser extension magic word '#icon'.

SELECT DISTINCT 
  page_title
FROM 
  page
  RIGHT JOIN 
  revision 
  ON page_id = rev_page
WHERE 
  rev_text_id
  IN (
    SELECT 
      old_id
    FROM 
      text
    WHERE 
      # old_text LIKE '%#icon%' 
      old_text REGEXP('#icon') # regex is easier to deal with
    )

A more complex query that summarizes some information about an article (You supply the article title)

SELECT 
  p.page_id 'id', 
  p.page_title 'title', 
  p.page_namespace 'namespace', 
  t.old_id 'latest text id', 
  t.old_text 'content', 
  r.rev_id, 
  r.rev_comment 'comment', 
  r.rev_user, 
  r.rev_user_text, 
  r.rev_parent_id 'previous revision' 
FROM 
  text t 
  RIGHT JOIN 
  revision r 
  ON t.old_id = r.rev_text_id 
  RIGHT JOIN 
  page p 
  ON r.rev_id = p.page_latest
WHERE 
  p.page_title = 'Main_Page'
