is because you have two tables in your query called wp_comments
also, do yourself a huge favour, learn to format your sql…

Thank you. The layout looks better and easier to read. Well I am a total noob in sql. What is the best way to remove the WP_comments in phpmyadmin? Just selecting it and delete it? Or will it work if I use this plugin and optimise the database: https://nl.wordpress.org/plugins/wp-optimize/
Yes, every table needs a unique key right. Wp_comments is not unique, so there is another one. That is interfering. That’s what I am understanding. Am I right? But when I look into it, I don’t see more wp_comments tables
Ok now I do understand it a bit more. So wp_comment and wp_commentmeta. A plugin. If I know which plugin this is causing, I can sent a message to the developer so he will able to fix it.
