入门CakePHP中3.x的相关数据

Icases表

$this->table('icases'); 
$this->displayField('name'); 
$this->primaryKey('id'); 

$this->belongsTo('Clients', [ 
    'foreignKey' => 'client_id' 
]); 
$this->hasMany('Documents', [ 
    'foreignKey' => 'icase_id' 
]); 
$this->belongsToMany('Users', [ 
    'foreignKey' => 'icase_id', 
    'targetForeignKey' => 'user_id', 
    'joinTable' => 'icases_users' 
    ]);

客户表

$this->table('clients'); 
$this->displayField('name'); 
$this->primaryKey('id'); 

$this->hasMany('Icases', [ 
    'foreignKey' => 'client_id' 
]); 
$this->belongsToMany('Users', [ 
    'foreignKey' => 'client_id', 
    'targetForeignKey' => 'user_id', 
    'joinTable' => 'clients_users' 
    ]);

IcasesUsers表

$this->table('icases_users'); 
$this->displayField('icase_id'); 
$this->primaryKey(['icase_id', 'user_id']); 

$this->belongsTo('Icases', [ 
    'foreignKey' => 'icase_id', 
    'joinType' => 'INNER' 
]); 
$this->belongsTo('Users', [ 
    'foreignKey' => 'user_id', 
    'joinType' => 'INNER' 
    ]);

在Icases表我有这样的SQL，它检索相关的客户，谁是在登录的用户有效的和未决案件数据。这工作得很好，直到用户设置过滤器，包括归档的案例以及积极和待批的这返回107077行，并且出现内存错误。有没有办法使用contains（）写这个sql，并在将数据提供给用户之前以块的形式获取数据，以便跨越内存限制？

$cases_data = TableRegistry::get('icases')->find('all') 
       ->select(['icases.id', 'icases.state', 'icases.client_id', 'icases.name', 'icases.age', 'clients.name']) 
       ->innerJoin('icases_users', 'icases_users.icase_id = icases.id') 
       ->where($conditions) 
       ->innerJoin('clients', 'clients.id = icases.client_id') 
       ->group(['icases.id']) 
       ->order(['clients.name' => 'ASC', 'icases.name' => 'ASC']) 
       ->execute() 
       ->fetchAll('assoc');
