我是 Yii 的初学者，我使用 GII 创建了一个 CURD 表。一切正常，但我只想通过放置 where 子句（例如“客户性别为男性”）从数据库中获取某些记录。我无法在 Gii 生成的代码中找到从数据库中获取数据的位置以及我需要的位置在代码中插入 WHERE 子句。

如您所知，Gii 生成的模型、控制器和视图文件。模型文件如下。我的视图使用 CGridView 生成 CRUD 表。

    public static function model($className = __CLASS__) {
    return parent::model($className);
}

/**
 * @return string the associated database table name
 */
public function tableName() {
    return 'test_prefixtbl_client_local';
}

/**
 * @return array validation rules for model attributes.
 */
public function rules() {
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('client_id', 'required'),
        array('client_id', 'length', 'max' => 15),
        array('surname, forename', 'length', 'max' => 20),
        array('title', 'length', 'max' => 6),
        array('status', 'length', 'max' => 8),
        array('dob', 'safe'),
        // The following rule is used by search().
        // Please remove those attributes that should not be searched.
        array('client_id, surname, forename, title, status, dob', 'safe', 'on' => 'search'),
    );
}

/**
 * @return array relational rules.
 */
public function relations() {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
    );
}

/**
 * @return array customized attribute labels (name=>label)
 */
public function attributeLabels() {
    return array(
        'client_id' => 'Client ID',
        'surname' => 'Surname',
        'forename' => 'Forename',
        'title' => 'Title',
        'status' => 'Status',
        'dob' => 'Date of birth (yyyy-mm-dd)',
        'actions' => 'Actions',
    );
}

/**
 * Retrieves a list of models based on the current search/filter conditions.
 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
 */
public function search() {
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.

    $criteria = new CDbCriteria;

    $criteria->compare('client_id', $this->client_id, true);
    $criteria->compare('surname', $this->surname, true);
    $criteria->compare('forename', $this->forename, true);
    $criteria->compare('title', $this->title, true);
    $criteria->compare('status', $this->status, true);
    $criteria->compare('dob', $this->dob, true);

    return new CActiveDataProvider($this, array(
                'criteria' => $criteria,
                'sort' => array(
                    'defaultOrder' => 'dob DESC',
                ),
            ));
}

您有两种方法来进行查询，一种使用查询生成器（此处为教程），如下所示：

$clientLocalArray = Yii::app()->db->createCommand()
->select()
->from("test_prefixtbl_client_local")
->where("gender = :gender", array(":gender"=>$gender))
->queryAll();

或者你可以像这样使用 Active Record 本身（教程在这里）：

$clientLocalArrayObjects = ClientLocal::model()->findAllByAttributes(array(
"gender" => $gender
));

有任何疑问，尽管问！:)
