我需要帮助,从我的原始SQL查询构建Laravel查询。我尝试了很多方法,没有找到我的运气。有谁能够帮助我?我的原始SQL代码如下。在Laravel 5中获取原始SQL查询的结果Eloquent
SELECT exams. * , count(question_details.exam_id) AS qus_enter
FROM exams
INNER JOIN question_details ON exams.id = question_details.exam_id GROUP BY exams.id
这是我已经试过:
$examListsID = DB::table('exams')
->join('question_details', function($join) {
$join->on('exams.id', '=', 'question_details.exam_id as qus_enter');
})
->whereraw('count(qus_enter) = exams.total_question')
->select('exams.id as examID','qus_enter','exams.total_question')
->count('qus_enter')
->groupby('exams.id')
->get();
$examLists = Addexam::where('id','=',$examListsID->examID)
,我得到这个错误:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'as
qus_enter
where count(qus_enter) = exams.total_question' at line 1 (SQL: select count(qus_enter
) as aggregate fromexams
inner joinquestion_details
onexams
.id
=question_details
.exam_id
asqus_enter
where count(qus_enter) = exams.total_question)
那么请让我们了解您其实试过 – lukasgeiter
我有两个表一是'考试'和'问题tion_details'。在我的“考试”表中,我设置了考试的总体问题,并在我的'question_details'中输入了与'exam_id'相关的问题。 我只想加载那个在'question_details'表中插入所有问题的考试。 –
我的意思是我希望你用Laravel查询代码更新你的答案(即使它不工作) – lukasgeiter
