you want to know where the sql is that inserts the comment?

inside wp-includes/comment.php :

function wp_insert_comment($commentdata) {
	global $wpdb;
	extract($commentdata, EXTR_SKIP);
	if ( ! isset($comment_author_IP) )
		$comment_author_IP = preg_replace( '/[^0-9., ]/', '',$_SERVER['REMOTE_ADDR'] );
	if ( ! isset($comment_date) )
		$comment_date = current_time('mysql');
	if ( ! isset($comment_date_gmt) )
		$comment_date_gmt = get_gmt_from_date($comment_date);
	if ( ! isset($comment_parent) )
		$comment_parent = 0;
	if ( ! isset($comment_approved) )
		$comment_approved = 1;
	if ( ! isset($user_id) )
		$user_id = 0;
	$result = $wpdb->query("INSERT INTO $wpdb->comments
	(comment_post_ID, comment_author, comment_author_email, comment_author_url, comment_author_IP, comment_date, comment_date_gmt, comment_content, comment_approved, comment_agent, comment_type, comment_parent, user_id)
	VALUES
	('$comment_post_ID', '$comment_author', '$comment_author_email', '$comment_author_url', '$comment_author_IP', '$comment_date', '$comment_date_gmt', '$comment_content', '$comment_approved', '$comment_agent', '$comment_type', '$comment_parent', '$user_id')
	");
	$id = (int) $wpdb->insert_id;
	if ( $comment_approved == 1)
		wp_update_comment_count($comment_post_ID);
	return $id;}
