关于 mysql:Converting custom sql query in to a dataprovider yii?

Converting custom sql query in to a dataprovider yii?

我正在尝试将以下查询转换为数据提供程序，以便它可以显示在 CGridView 中。我曾尝试使用 CArrayDataProvider，但到目前为止还没有任何运气，任何帮助将不胜感激！

这里是查询

public function getTeamsByLevelIdAndCompetitionId($levelId, $competitionId)
{
$query ="SELECT t.*,
(SELECT COUNT(*)
FROM tbl_competition_teams ct
WHERE ct.team = t.id
AND ct.competition = :competitionId) AS 'inCompetition'
FROM tbl_teams t
WHERE t.level = :levelId";

$params = array(
'levelId' => $levelId,
'competitionId' => $competitionId
);

$result = array();
$teams = $this->findAllBySQL($query, $params);
return $teams;
}

这就是我尝试将其放入 CArrayDataProvider 的方式：

public function getTeamsByLevelIdAndCompetitionId($levelId, $competitionId)
{
$rawData = Yii::app()->db->createCommand("SELECT t.*,
(SELECT COUNT(*)
FROM tbl_competition_teams ct
WHERE ct.team = t.id
AND ct.competition = :competitionId) AS 'inCompetition'
FROM tbl_teams t
WHERE t.level = :levelId")->queryAll();

$params = array(
'levelId' => $levelId,
'competitionId' => $competitionId
);

return new CArrayDataProvider($rawData, array(
'id'=>'id',
'sort'=>array(
'attributes'=>array(
'id', 'title', 'club', 'level', 'inCompetition',
),
),

));
}

但这给了我错误"CDbCommand未能执行SQL语句：SQLSTATE [HY093]：无效参数号：未绑定参数。"

这是我的团队表

CREATE TABLE `tbl_teams` (

`title` varchar(35) NOT NULL DEFAULT '',

`club` int(10) unsigned DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=2952 ;

`competition` int(10) unsigned NOT NULL DEFAULT '0',

`seasonId` int(11) NOT NULL DEFAULT '3',
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=126320 ;

提前一百万感谢您的任何建议！

也许问题是你 queryAll() 执行查询。此时您没有将值分配给您的参数

$rawData = Yii::app()->db->createCommand("SELECT t.*,
(SELECT COUNT(*)
FROM tbl_competition_teams ct
WHERE ct.team = t.id
AND ct.competition = $competitionId) AS 'inCompetition'
FROM tbl_teams t
WHERE t.level = $levelId")->queryAll();

您也可以尝试重写您的查询。

AND ct.competition = :competitionId) AS 'inCompetition'
FROM tbl_teams t
WHERE t.level = :levelId";

$command= Yii::app()->db->createCommand($query);
$command->bindValue(':levelId', $levelId);
$command->bindValue(':competitionId', $competitionId);
$rawData = $command->queryAll();
