php - Yii 查找查询结果 - 没有表结构

Question

我正在对模型使用以下查询

$criteria = new CDbCriteria; 
$criteria->condition='brand_id=3';
$model=Models::model()->find($criteria);

它给出了表结构和关系表结构的结果，如下所示

Models Object ( [_md:CActiveRecord:private] => CActiveRecordMetaData Object ( [tableSchema] => CMysqlTableSchema Object ( [schemaName] => [name] => models [rawName] => `models` [primaryKey] => model_id [sequenceName] => [foreignKeys] => Array ( [brand_id] => Array ( [0]

如何仅在 yii 查询中获取表数据

Answer 1

返回的数据是一个 CActiveRecord 对象。返回的数据有这样的复杂性是正常的。如果你只想获取 DB 值，你应该使用来自 Yii 的 DAO 功能或 Query Builder 功能！

• Yii 中的 DAO 指南
• yii 指南中的查询生成器

使用查询生成器的示例：

$model = Yii::app()->db->createCommand()
    ->select('*')
    ->from('your_table t')
    ->where('brand_id=:id', array(':id'=>3))
    ->queryRow();

使用 DAO 的示例：

$connection=Yii::app()->db;
$command=$connection->createCommand('SELECT * FROM your_table WHERE id =:id');
$command->bindParam(":id", 3, PDO::PARAM_INT);
$row=$command->queryRow();

Answer 2

我不确定你到底想要什么。但是你可以看看我的样品来得到它。

$words = Word::model()->findAll();
$data=array_map(create_function('$m','return $m->getAttributes();'),$words);
var_dump($data);

我使用 ActiveRecord 从我的表词中获取所有记录，当然，您可以应用您的标准而不是“findAll”并根据您的需要进行不同的设置。这是我的结果。

array (size=3)
  0 => 
    array (size=9)
      'word_id' => string '1' (length=1)
      'name' => string 'a' (length=1)
      'sound_file' => null
      'length' => string '1' (length=1)
      'type' => null
      'meaning' => null
      'priority' => string '1' (length=1)
      'first_char' => string 'a' (length=1)
      'word_count' => string '1' (length=1)
  1 => 
    array (size=9)
      'word_id' => string '2' (length=1)
      'name' => string 'b' (length=1)
      'sound_file' => null
      'length' => string '1' (length=1)
      'type' => null
      'meaning' => null
      'priority' => string '1' (length=1)
      'first_char' => string 'b' (length=1)
      'word_count' => string '1' (length=1)
  2 => 
    array (size=9)
      'word_id' => string '3' (length=1)
      'name' => string 'c' (length=1)
      'sound_file' => null
      'length' => string '1' (length=1)
      'type' => null
      'meaning' => null
      'priority' => string '1' (length=1)
      'first_char' => string 'c' (length=1)
      'word_count' => string '1' (length=1)
