Search the wordpress content management system database

WordPress is by far the most popular content management system for blog hosting. The wordpress content management system uses the mysql database. If you have a big site with a large number of posts then it can be handy to search the content of every post to find certain text. Sometimes you may even need to replace certain keywords with other keywords. As with most content management setups there is probably a plugin that will do just that, but it is far easier to just use basic sql if you know the structure of the wordpress database.
Within either phpmyadmin or mysqlyog (depending on what you are using) you can use this sql query to find the text that you are looking for:


select * from wp_posts where post_content 
like '%content management system%';

The ID that you get back is basically the page id. For example, if I query my database and get back an id of 13449 then that content will reside at http://codytaylor.org/?p=13449. Other useful columns are the post_content which is the content text of the post, post_name which is the title of the post, and the guid which is the full url (before mod_rewrite changes it) so you don’t have to copy and paste the id and append it to your url.

If you need to search and replace some text in more than one post then you can use this sql :


UPDATE wp_posts SET post_content = REPLACE (
post_content, 'content management system', 'CMS');

That SQL query will replace the ‘content management system’ with ‘CMS’.
