Question

下面的代码工作正常但是当我用相同的DB复制整个cakephp3项目时，我得到以下错误。由于相同的代码在其他地方工作，我不确定如何解决这个问题。我正在使用最新的Wamp64，win10。 cakephp3项目的其余部分工作正常。另一台计算机使用了wamp64和win7。

有解决方案，但这涉及更改数据库设置，我更喜欢更改代码。

Error related to only_full_group_by when executing a query in MySql

错误：SQLSTATE [42000]：语法错误或访问冲突：1055 SELECT列表的表达式＃11不在GROUP BY子句中，并且包含非聚合列'aptutori_test.Lessons.id'，它在功能上不依赖于GROUP BY中的列条款;这与sql_mode = only_full_group_by

不兼容

 $options['fields'] = array('DISTINCT Student.* ','Guardian.* ');

        $options['conditions'] = array('Lessons.tutor_id'  =>  $tutorId,'Student.student_inactive'=>0,
            'Lessons.lesson_date >='=> $currDate, 'Lessons.makeup_lesson' => 0,'Lessons.forefit' => 0);


        $fields = [
            'Student.first_name','Student.last_name','Student.id',"Student.address_street","Student.address_suburb","Student.address_postcode","Student.class_year",
            "Guardian.id",'Guardian.guardian_first_name',"Guardian.guardian_last_name"
        ];

        $query = $this->Lessons->find('all');

        $students = $query->where($options['conditions'])->autoFields(true)
            ->select($fields)->distinct(["Student.id",'Guardian.id'])
            ->join($options['joins'])
        ;

        $this->set( 'student',$students);

以下是可以在不更改数据库设置的情况下解决问题的代码。

$students = $this->Lessons->find()
                            ->contain([
                                'Students',
                                'Students.Guardians'])
                            ->select([
                                'Students.last_name',
                                'Students.first_name',
                                'Students.id',
                                'Lessons.student_id',
                                'Lessons.tutor_id',
                                'Students.has_credit',
                                'Lessons.student_id', 
                                'Lessons.id',
                                'Students.class_year',
                                'Lessons.subject_id',
                                'Guardians.guardian_last_name', 
                                'Guardians.guardian_first_name',
                                'Students.address_street',
                                'Students.address_suburb',
                                'Students.address_postcode',
                                'Guardians.id'])
                            ->where([
                                'Lessons.tutor_id' => $tutorId, 
                                'Students.student_inactive' => 0,
                                'Lessons.lesson_date >=' => $currDate, 
                                'Lessons.cancelled_lesson' => 0,
                                'Lessons.forefit' => 0])
                            ->order([
                                'Lessons.lesson_date' => 'ASC', 
                                'Lessons.start_time' => 'ASC'])
                            ->hydrate(true);

$gdata = array();
$studentIds = array();

foreach ($students as $i => $item) {

    if (in_array($item['student']['id'], $studentIds)) {
        continue;
    } else {

        array_push($studentIds,$item['student']['id']);

        $gdata[$i]['student']['id'] = $item['student']['id'];
        $gdata[$i]['student_id'] = $item['student_id'];
        $gdata[$i]['student']['first_name'] = $item['student']['first_name'];
        $gdata[$i]['student']['last_name'] = $item['student']['last_name'];
        $gdata[$i]['student']['guardian']['guardian_first_name'] = $item['student']['guardian']['guardian_first_name'];
        $gdata[$i]['student']['guardian']['guardian_last_name'] = $item['student']['guardian']['guardian_last_name'];
        $gdata[$i]['student']['address_street'] = $item['student']['address_street'];
        $gdata[$i]['student']['address_suburb'] = $item['student']['address_suburb'];
        $gdata[$i]['student']['address_postcode'] = $item['student']['address_postcode'];
        $gdata[$i]['student']['class_year'] = $item['student']['class_year'];
    }
}

找到记录的相同cakephp3代码在另一台计算机上不起作用
