Question

构建以下查询：

$q = $this
    ->createQueryBuilder('a')
    ->select('a')
    ->where('a.account = :accountId')
    ->andWhere('a.organization = :organization_id')
    ->setParameters(
        array(
            'accountId' => $account_id,
            'organization_id' => $organization_id,
        )
    )
    ->getQuery();

调用getResult（）（并计算结果集）时：$attributes = count($q->getResult());结果是返回1行（这是不正确的）。

但是，当调用getResultArray $attributes = count($q->getArrayResult());时结果是2（这是正确的）

表架构：

CREATE TABLE 'accountattribute' (
  'account_id' int(11) NOT NULL,
  'organization_id' int(11) NOT NULL,
  'dataKey' varchar(255) COLLATE utf8_unicode_ci NOT NULL DEFAULT '',
  'dataValue' text COLLATE utf8_unicode_ci NOT NULL,
  'updated' datetime NOT NULL,
  'created' datetime NOT NULL,
  PRIMARY KEY ('account_id','organization_id','dataKey'),
  KEY 'organization_id' ('organization_id'),
  CONSTRAINT 'accountattribute_ibfk_1' FOREIGN KEY ('account_id') REFERENCES 'accounts' ('id'),
  CONSTRAINT 'accountattribute_ibfk_2' FOREIGN KEY ('organization_id') REFERENCES 'organizations' ('id')
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

预期结果：

    [
    {
        data_key: "foo",
        data_key: "bar",
        updated: "2014-05-10T21:09:56+0000",
        created: "2014-05-10T21:09:56+0000",
        account: {
            id: 1,
            display_name: "Test Account",
            organization: {
                id: 1,
                display_name: "NAME"
            },
            active: true,
            deleted: false,
            updated: "2014-05-09T15:25:16+0000",
            created: "2014-05-09T15:25:16+0000"
        },
        organization: {
            id: 1,
            display_name: "NAME"
        },
    },
    {
        data_key: "nice",
        data_key: "ace",
        updated: "2014-05-11T01:04:43+0000",
        created: "2014-05-11T01:04:43+0000",
        account: {
            id: 1,
            display_name: "Test Account",
            organization: {
                id: 1,
                display_name: "NAME"
            },
            active: true,
            deleted: false,
            updated: "2014-05-09T15:25:16+0000",
            created: "2014-05-09T15:25:16+0000"
        },
        organization: {
            id: 1,
            display_name: "NAME"
        },
    }
]

实际结果（使用getResult时）

[
    {
        account: {
            id: 1,
            display_name: "Test Account",
            organization: {
                id: 1,
                display_name: "NAME"
            },
            active: true,
            deleted: false,
            updated: "2014-05-09T15:25:16+0000",
            created: "2014-05-09T15:25:16+0000"
        },
        organization: {
            id: 1,
            display_name: "NAME"
        },
        data_key: "foo",
        data_value: "bar",
        updated: "2014-05-10T21:09:56+0000",
        created: "2014-05-10T21:09:56+0000"
    }
]

实际结果（使用getArrayResult时）

[
    {
        account: {
            id: 1,
            display_name: "Test Account",
            organization: {
                id: 1,
                display_name: "NAME"
            },
            active: true,
            deleted: false,
            updated: "2014-05-09T15:25:16+0000",
            created: "2014-05-09T15:25:16+0000"
        },
        organization: {
            id: 1,
            display_name: "NAME"
        },
        data_key: "foo",
        data_value: "bar",
        updated: "2014-05-10T21:09:56+0000",
        created: "2014-05-10T21:09:56+0000"
    }
]

在此链接中：http://docs.doctrine-project.org/en/2.1/reference/dql-doctrine-query-language.html

Query＃getResult（）：检索对象的集合。结果是   要么是一个简单的对象集合（纯粹的），要么是一个数组   对象嵌套在结果行中（混合）。

Query＃getArrayResult（）：检索一个数组图（嵌套数组）   在很大程度上可以与生成的对象图互换   查询＃getResult（）是为了只读目的。
An array graph can differ from the corresponding object graph in certain scenarios due to the difference of the identity semantics between arrays and objects.
我认为关系映射会引起这种情况。

更新1： 我找到了类似的问题解决了。请检查一下：

Doctrine Query getARrayResult

Doctrine相同查询，getResult vs getArrayResult返回不同的结果
