我发现，当我不断向谷歌做出了回答，这是为我工作的代码：

try{ 
     $sqry = $con->prepare("SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(WrkHrs))) AS MHrsTotal, SEC_TO_TIME(SUM(TIME_TO_SEC(Overtime))) AS MOvtTotal, 
     SEC_TO_TIME(SUM(TIME_TO_SEC(TotalOT))) AS GMTotal FROM actualot WHERE EmpID = :id AND ValidDate BETWEEN DATE(:start) AND 
     DATE(:end) GROUP BY EmpID ORDER BY ValidDate ASC"); 
     $sqry->bindParam(':id',$rs['EmpID']); 
     $sqry->bindParam(':start',$from); 
     $sqry->bindParam(':end',$to); 
     $sqry->execute(); 
    } 
    catch(PDOException $e){ 
     echo $e->getMessage(); 
     exit(); 
    }
