我可以使用 yii CSqlDataProvider 执行两个或多个 sql 语句吗？

Question

我试图使用 yii 在以下 sql 语句中获得很少的结果，但是有一些问题......！

 $sql="SET @pStat=-1; SET @pdt=0;  SELECT * FROM (SELECT !li.gen  AS id,li.logAt, getDuration(gen,logAt) AS duration FROM os_loggerinfo li ) AS a WHERE a.duration>0;";

$count=count(Yii::app()->db->createCommand($sql)->query()); 

$dataProvider=new CSqlDataProvider($sql, array(
            'totalItemCount'=>$count,
            'pagination'=>array(
                'pageSize'=> 10,
            ),
        ));

Answer 1

您正在使用 count(Yii::app()->db->createCommand($sql)->query());，我不确定，但我认为 query() 仅返回 true 或 false。尝试使用 queryAll() 或者如果它只是单行，请使用 queryRow()

Answer 2

$sql="SET @pStat=-1; SET @pdt=0;  SELECT |selectPart| FROM (SELECT !li.gen  AS id,li.logAt, getDuration(gen,logAt) AS duration FROM os_loggerinfo li ) AS a WHERE a.duration>0;";
$selectPart = 'COUNT(1) as cnt';
$count = Yii::app()->db->createCommand(str_replace('|selectPart|', $selectPart, $sql))->queryScalar();
$sql = str_replace('|selectPart|','*',$sql);
$dataProvider=new CSqlDataProvider($sql, array(
        'totalItemCount'=>$count,
        'pagination'=>array(
            'pageSize'=> 10,
        ),
    ));

Answer 3

尝试使用 CArrayDataProvider 而不是 CSqlDataProvider：

$sql="SET @pStat=-1; SET @pdt=0;  SELECT * FROM (SELECT !li.gen  AS id,li.logAt, getDuration(gen,logAt) AS duration FROM os_loggerinfo li ) AS a WHERE a.duration>0;";
$result=Yii::app()->db->createCommand($sql)->queryAll(); 
$count=count($result);
$dataProvider=new CArrayDataProvider($result, array(
            'totalItemCount'=>$count,
            'pagination'=>array(
                'pageSize'=> 10,
            ),
        ));
