I need to remove this these links. already tested this mysql but it's not working

UPDATE wp_posts SET post_content = REPLACE(post_content, substring_index( substring_index(post_content, 'href="', -1),  '"', 1),'');
UPDATE wp_posts SET post_content = REPLACE(post_content, '<a href="">','');
UPDATE wp_posts SET post_content= REPLACE(post_content, '<a href="" target="_blank">','');
UPDATE wp_posts SET post_content= REPLACE(post_content, '</a>','');

I suggest you , use wp_strip_all_tags wordpress function for example :

global $wpdb;
$wpdb->query("update `wp_posts` set post_content = ".wp_strip_all_tags( $string ) ....);
