Сводная таблица MySql в Yii CActiveDataProvider

У меня есть структура таблицы следующим образом:

CREATE TABLE IF NOT EXISTS `CustomValue` (
`id` int(11) NOT NULL,
`customFieldId` int(11) NOT NULL,
`relatedId` int(11) NOT NULL,
`fieldValue` text COLLATE utf8_unicode_ci,
`createdAt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

CREATE TABLE IF NOT EXISTS `CustomField` (
`id` int(11) NOT NULL,
`customTypeId` int(11) NOT NULL,
`fieldName` varchar(64) COLLATE utf8_unicode_ci DEFAULT NULL,
`relatedTable` varchar(64) COLLATE utf8_unicode_ci DEFAULT NULL,
`defaultValue` text COLLATE utf8_unicode_ci,
`sortOrder` int(11) NOT NULL DEFAULT '0',
`enabled` char(1) COLLATE utf8_unicode_ci DEFAULT '1',
`listItemTag` char(1) COLLATE utf8_unicode_ci DEFAULT NULL,
`required` char(1) COLLATE utf8_unicode_ci DEFAULT '0',
`onCreate` char(1) COLLATE utf8_unicode_ci DEFAULT '1',
`onEdit` char(1) COLLATE utf8_unicode_ci DEFAULT '1',
`onView` char(1) COLLATE utf8_unicode_ci DEFAULT '1',
`listValues` text COLLATE utf8_unicode_ci,
`label` varchar(64) COLLATE utf8_unicode_ci DEFAULT NULL,
`htmlOptions` text COLLATE utf8_unicode_ci
) ENGINE=MyISAM AUTO_INCREMENT=17 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;


CREATE TABLE IF NOT EXISTS `User` (
`id` bigint(20) NOT NULL,
`address1` text COLLATE utf8_unicode_ci,
`mobile` varchar(15) COLLATE utf8_unicode_ci DEFAULT NULL,
`name` varchar(45) COLLATE utf8_unicode_ci DEFAULT NULL,
`firstName` varchar(64) COLLATE utf8_unicode_ci DEFAULT NULL,
`lastName` varchar(64) COLLATE utf8_unicode_ci DEFAULT NULL
) ENGINE=MyISAM AUTO_INCREMENT=4034 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Пожалуйста, проверьте скрипку SQL. http://sqlfiddle.com/#!9/1a579/3

Данные загружаются с этим запросом.

SET @Colvalues = NULL;
SET @sql = NULL;

SELECT
GROUP_CONCAT(DISTINCT CONCAT('MAX(IF(f.fieldName = ''',
f.fieldName, ''', COALESCE(v.fieldValue, f.defaultValue) , NULL)) AS ', '''', f.fieldName , '''')
) INTO @Colvalues
FROM customField AS f
INNER JOIN Customvalue AS v ON f.Id = v.customFieldId;


SET @sql = CONCAT('SELECT
u.*, v.relatedId, v.CreatedAt, ', @Colvalues , '
FROM customField AS f
INNER JOIN Customvalue AS v ON f.Id = v.customFieldId RIGHT JOIN User u on u.id = v.relatedId
GROUP BY   v.relatedId, v.CreatedAt;');

PREPARE stmt
FROM @sql;

EXECUTE stmt;

Как я могу сформировать это в CDbCriteria объект и CActiveDataProvider ? Мне нужно загрузить эти данные в cgridview и разрешить поиск пользовательских столбцов с cgridview filters,

В настоящее время это то, что я сделал:

public function searchPeople($customFields)
{
$criteria = new CDbCriteria;
$criteria->together = true;

$criteria->compare('address1', $this->address1, true);
$criteria->compare('mobile', $this->mobile, true);
$criteria->compare('t.firstName', $this->firstName, true);
$criteria->compare('t.lastName', $this->lastName, true);


if (!empty($customFields)) {
$criteria->join .= ' LEFT OUTER JOIN CustomValue cv ON cv.relatedId=t.id';
//foreach ($customFields as $k => $customField) {
//print_r($customField); exit;
//}
}

вывод print_r ($ customField):

CustomValue Object
(
[fieldStyle] =>
[fieldName] => ALTERNATEEMAIL
[fieldLabel] => Alternate Email
[fieldType] => text
[fieldTag] =>
[fieldIsRequired] => 1
[fieldDefaultValue] =>
[listValues] =>
[_new:CActiveRecord:private] => 1
[_attributes:CActiveRecord:private] => Array
(
[customFieldId] => 14
[fieldValue] =>
)
