从la中的另一个表中选择列中的表中选择

Question

我有以下查询

SELECT * FROM answers where (id_question in (select id from questions where id_quiz = 3)) 

我需要知道如何用laravel eloquent

来写它

Answer 1

Answer::whereIn('id_question', function($query) {
    $query->table('questions')->where('id_quiz', 3)
})->get();

Answer 2

table方法不再有效，请改用from方法

Answer::whereIn('id_question', function($query) {
    $query->from('questions')->where('id_quiz', 3)
})->get();
