SQLSTATE [42000]：语法错误或访问冲突：1064 laravel

Question

在我的 Laravel 代码中，我使用DB来访问数据库。 在名为showTeacherList的 controller function 中，我试图获取每位老师的所有作品。 但是 Laravel 返回此错误。 当我转储查询时，将其复制到phpmyadmin并运行，它可以工作。 我的代码：

function showTeacherList($login){
    $select_result = DB::select('select id, name from kafedra where login = ?', [$login]);
    $kafedra_id = $select_result[0]->id;
    $teachers = DB::select('select id, name from teacher where kafedra_id = ?', [$kafedra_id]);
    $teacher_works = [];
    $i = 0;
    foreach ($teachers as $teacher) {
        $teacher_works[$i] = DB::select('select * from work where teacher_id = ?' [$teacher->id]);
        $i++;
    }
    return view('kafedra/teacher_list', ['login' => $login, 'name' => $select_result[0]->name, 'teachers' => $teachers, 'teacher_works' => $teacher_works]);
}

请帮忙，谢谢

您的DB::select语句中存在语法错误，特别是在您的foreach循环中。 您错过了分隔query和bindings的逗号。

代替：

$teacher_works[$i] = DB::select('select * from work where teacher_id = ?' [$teacher->id]);

和：

$teacher_works[$i] = DB::select('select * from work where teacher_id = ?', [$teacher->id]);
