说明：把查询条件作为参数（如例2），比较安全，可直接避免注入。要是直接用在SQL语句中，最好要经过防注入处理。
$sql = "select sum(if(starttime>'09:00:00',1,0)) as late,
sum(if(endtime<'18:00:00',1,0)) as early
from present where userid=115 and date between '2009-12-1' and '2009-12-31'"
$results = $db->createCommand( $sql)->query();
foreach( $results as $result){
echo $result['late']," and ", $result['early']," /n";
}
