Question

任何人都可以帮助我将以下查询从ZEND格式更改为Yii2格式，

$select = $db->select();
$select->from(array('u' => 'user'), array('user_id', 'name', 'dob'))
       ->join(array('ua' => 'User_Address'), 'ua.user_id = u.user_id', array())
       ->join(array('a' => 'Address'), 'a.address_id = ua.address_id', array('address_id', 'street', 'city', 'state', 'country'));

提前致谢，

你可以使用例如：

$rows = (new \yii\db\Query())
    -select(['u.user_id', 'u.name', 'u.dob', Address.street, Address.city , Address.state, Address.country ])
    ->from('user u' ) 
    ->join('INNER JOIN', 'User_Address', 'User_Address.user_id = u.id')
    ->join('INNER JOIN', 'Address', 'Address.user_id = User_Address.address_id AND ')    
    ->all();
