I used `get_comment()` but its parameter is `$comment_ID` which I has to enter manually for previous comments from `wp_comments` instead of that I need to get current comment means last updated comment author name based on the `post_ID`. However `wp_posts` and `wp_comments` are related with `post_ID` and `comment_post_ID`, so I can use SQL query to get comment_ID I tried `$wpdb->get_results('select comment_ID from wp_comments where comment_post_ID = 1')` its even manual process but at-least I want to pass comment_ID by fetching from database but could't do that query results nothing so is there any way to get current comment_ID for a post_ID I can get post_id by `$post->ID`.
