MySQL has a built in function to perform string replace (just like PHP str_replace) thru the query. I just perform a MySQL string replace at a website migration and everything work like a charm. This MySQL string replace function really save me a lot of time! Imagine if i’m going to edit the record one by one, and there is 100 record, i think i’m going to be crazy after the manual edition.
To perform string replace (str_replace) in MySQL, you can use the query below:-
- For example: I’m going to do string replace at my ‘post_content’ field in ‘wp_posts’ table.
Replace with: http://www.xyx.com
You may run the query below to perform the string replace function:-
UPDATE wp_posts SET post_content = REPLACE(post_content, 'http://www.abc.com','http://www.xyz.com');
- Done. Now all the record in post_content should be updated!
