【解决方案1】：

使用raw query 喜欢：

DB::select(DB::raw('SELECT u.*,(
SELECT COUNT(*) FROM (
    SELECT id,author_id FROM posts p
    UNION ALL
    SELECT id, author_id FROM updates up
) total_table WHERE author_id = u.id) as total_post FROM users u ORDER BY total_post'));

【解决方案2】：

或者你可以使用DB::satement来做到这一点

$query='SELECT u.*,(SELECT COUNT(*) FROM (
SELECT id,author_id FROM posts p
UNION ALL
SELECT id, author_id FROM updates up) total_table WHERE author_id = u.id) as total_post FROM users u ORDER BY total_post';
$data=DB::statement($query);

像这样。
