入門CakePHP中3.x的相關數據

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' 
    ]);

客戶表

$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表我有這樣的SQL，它檢索相關的客戶，誰是在登錄的用戶有效的和未決案件數據。這工作得很好，直到用戶設置過濾器，包括歸檔的案例以及積極和待批的這返回107077行，並且出現內存錯誤。有沒有辦法使用contains（）寫這個sql，並在將數據提供給用戶之前以塊的形式獲取數據，以便跨越內存限制？

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