我正在尝试在CREATE DEFINER=`root`@`localhost` PROCEDURE `getTotalVolumeByDateRange`(start_time timestamp, time_interval int)
BEGIN
DECLARE max_date date;
DECLARE min_date date;
DECLARE temp_end_date date;
SET min_date = DATE(start_time);
SELECT DATE(MAX(createdAt)) FROM VolumeData INTO max_date;
-- SELECT max_date, min_date;
CREATE TEMPORARY TABLE tempRangedVolumeData(
start_date date,
end_date date,
Volume decimal(5,2)
);
while min_date <= max_date DO
SET temp_end_date = DATE_ADD(min_date, Interval time_interval DAY);
INSERT INTO tempRangedVolumeData(start_date, end_date, Volume)
SELECT min_date, temp_end_date, SUM(Volume)
FROM VolumeData
WHERE DATE(CreatedAt) BETWEEN min_date and temp_end_date;
SET min_date = DATE_ADD(min_date, Interval time_interval+1 DAY);
end while;
select
start_date,
end_date,
coalesce(Volume,0) as Volume
from tempRangedVolumeData;
drop table tempRangedVolumeData;
END
