What you’ll need

Before you begin this guide you’ll need the following:

DELETE from wp_comments WHERE comment_approved = 'spam'

Remove all approved comments in WordPress:

Note that depending on your WordPress setup, the prefix of comments table (wp_ in this case) can be different.

Simply copy and paste the query you want to run into the SQL tab and press Go button.
