Change a line across a bunch of posts in WordPress

To change a line can  in posts across many in WordPress, can manually be a “pain-in-the-ass”-task. But can actually be done quite easily with a single line of MySQL-code, executed from the db-admin-interface (phpmyadmin etc.)

UPDATE wp_posts SET post_content=REPLACE(post_content, 'text-to-be-replaced', 'text-to-insert')

To be more understandable, you use it like this

UPDATE Table-Name SET Field-Name=REPLACE(Field-Name, 'Text-To-Be-Replaced', 'Text-To-Insert');

With this one line, mysql searches the table ‘wp_posts’ and replace all occurrences of the text-snippet it can find, and you are done!

The Other method is to use the wordpress-plugin Search and Replace, which runs from the wordpress admin-section (see Tools-menu!), and you can select which tables, in the database wordpress is installed in, to be searched!

In the mysql-command, the table is stated second after ‘UPDATE’!
