Find and replace text in MySQL and Oracle

Today someone told me that they have a blog with over 300 posts and just changed their URL, the problem is that the new blog still had reference to their previous blog's url. And all the images, and reference were to the previous URL which had a 401 re-direct to the new blog. The images, etc were already deleted from the previous blog and imported into the new URL.

He was actually going to update every single entry. I recommended that it the blog has all posts in it's SQL database and had to find all the fields which contained the text (old url address), with the new text (new url ).

Now I will show you and easy way to update this.

Go to your database SQL screen and type in as follows

UPDATE [your_table_name] SET [your_table_field] = REPLACE([your_table_field], '[string_to_find]' , '[string_to_be_replaced]');

example
UPDATE my_posts SET post_content = REPLACE(post_content, 'www.oldurl.com' , 'www.newurl.com');

So armed with only one query per column table combination, you can easily update your blog or database with the new text.
