Question

我试图使用yii获取以下sql语句的结果很少，但是有些错误...... !!!

 $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()只返回true或false。尝试使用queryAll()，或者只使用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代替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,
            ),
        ));

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