教你如何把SQL语句转成TP5?

具体问题描述：

求大神帮我把这段原生SQL语句转成TP5的谢谢！就是Db::('name')->这种链式操作的

'select a.id, a.title,a.create_time,a.is_solve,count(b.qid) as answer_count from fa_question a,fa_answer b where a.id=b.qid and a.is_solve=0 group by b.qid order by answer_count DESC LIMIT 6';

实现方法：

Db::table(['fa_question '=>'a','think_role'=>'b'])     ->field('a.id, a.title, a.create_time, a.is_solve, count(b.qid) as answer_count)     ->where(' a.id=b.qid and a.is_solve=0')     ->group('b.qid')     ->order('answer_count desc')     ->limit(6)     ->select()
