如何在varchar列中更改URL的域？

Question

I have a database structure where one of my columns (innerLink) has a URL within it.

So that innerLink column will have a URL structured as follows http://www.123456.com/forums/showthread.php?t=123456

I wanted to change the http://www.123456.com to a wholly different URL --> http://789.123.com without affecting the rest of the URL structure (ie. /forums/showthread.php?t=123456 )

I need this change to hit every URL in that column that is on the 123456 domain. I have other URLs such as cnn.com or msnbc.com so I dont want those affected. The change should only be to make www.123456.com to 789.123.com

I've never done this type of manipulation with MYSQL before, so was hoping for a bit of guidance before I hose my entire database of about 4000 records :) I will be doing this through PHPMYADMIN

Thanks for any help!!

Answer 1

您要使用REPLACE（）字符串函数

UPDATE `table` SET `innerLink` = REPLACE('www.123456.com', '789.123.com');
