у меня есть эта рабочая процедура mysql, есть ли способ сделать это для цикла for для проверки времени, чтобы минимизировать код и это код процедуры, который я хочу усреднить за 2 часа в течение одного дня, день определяется параметром daydate и время от «00:00:00» до «24:00:00»

, поэтому я нашел решение, используя для 

CREATE DEFINER=`root`@`localhost` PROCEDURE `proceduregetavgperdayfor`(IN daydate date)
BEGIN

declare TimeVar Time;
declare Step Time;
DROP TABLE if exists ResultTable;
CREATE TEMPORARY table ResultTable (`Anger` float,`Contempt` float,`Disgust` float,`Fear` float,`Happiness` float,`Neutral` float,`Sadness` float,`Surprise` float,`Houre` varchar(50));

SET TimeVar='00:00:00';
SET Step='02:00:00';

loop1: LOOP
insert  into ResultTable
select IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Happiness`), 2),0) AS `Happiness`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Anger`), 2),0) AS `Anger`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Contempt`), 2),0) AS `Contempt`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Disgust`), 2),0) AS `Disgust`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Fear`), 2),0) AS `Fear`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Neutral`), 2),0) AS `Neutral`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Sadness`), 2),0) AS `Sadness`,
        IFNULL(ROUND(AVG(`viewemotionavgbydateandtime`.`Surprise`), 2),0) AS `Surprise`,
        TimeVar as "Hour"
        from viewemotionavgbydateandtime where `Time` >= TimeVar and `Time` < TimeVar+Step and `Date`=daydate;
    SET TimeVar=TimeVar+Step;
    IF TimeVar>'24:00:00' THEN 
    LEAVE loop1;
    END IF;
    ITERATE loop1;
    END Loop loop1;
    select * from ResultTable;
END
