How to Change/Update links with MySQL
You can use the MySQL replace command to search and replace text inside database tables.
For updating the URL we need to run the below query over multiple tables and fields.
update TABLE_NAME set FIELD_NAME = replace(FIELD_NAME, ‘find string’, ‘replace string’);
Open the PHPMyAdmin panel and log in.
Click the WordPress database.
For replacing the URL across all database tables, Click on SQL tab and in the panel type the below code:
UPDATE wp_options SET option_value = replace(option_value, ‘Existing URL’, ‘New URL’) WHERE option_name = ‘home’ OR option_name = ‘siteurl’;
UPDATE wp_posts SET post_content = replace(post_content, ‘Existing URL’, ‘New URL’);
UPDATE wp_postmeta SET meta_value = replace(meta_value,’Existing URL’,’New URL’);
UPDATE wp_usermeta SET meta_value = replace(meta_value, ‘Existing URL’,’New URL’);
UPDATE wp_links SET link_url = replace(link_url, ‘Existing URL’,’New URL’);
UPDATE wp_comments SET comment_content = replace(comment_content , ‘Existing URL’,’New URL’);
If you have images linked in your posts then you need to run the following additional queries.
