检查示例查询，

$GroupAccountIds = $this->ClientForm->find(
'list',
[
    'joins' => [
        [
            'table'=>'group_accounts',
            'alias' => 'GroupAccount',
            'type' => 'INNER',
            'conditions' => [
                'ClientForm.created_group_account_id = GroupAccount.group_account_id',
                'ClientForm.deleted IS NULL'
            ]
        ],
    ],
    'conditions' => [
        'GroupAccount.group_account_category_id' => $smsfCategoryId,
        'GroupAccount.deleted' => null,
    ],
    'fields' => [
        'ClientForm.created_group_account_id',
