假如原始数据为每5秒一个数据，现在想展示为每4分钟一条数据，先按照分钟数把除以4余数为0的行选出来，在按照 年月日 时分，做组内排序（窗函数ROW_NUMBER），最后再拿出序号为1的行。
以下每分钟一条
with data_02 AS
(
SELECT *
,ROW_NUMBER() OVER ( PARTITION BY DATE_FORMAT(UploadTime,'%Y-%m-%d %H:%i') ORDER BY ID) Seq
FROM TprRecord
ORDER BY id DESC
)
SELECT * FROM data_02 WHERE Seq=1 ORDER BY id DESC LIMIT 500;

WITH data_01 AS
(
SELECT *
FROM TprRecord tr
WHERE MOD(MINUTE(uploadtime),4)=0
ORDER BY id DESC
),
data_02 AS
(
SELECT *
,ROW_NUMBER() OVER ( PARTITION BY DATE_FORMAT(UploadTime,'%Y-%m-%d %H:%i') ORDER BY ID) Seq
FROM data_01
)
SELECT * FROM data_02 WHERE Seq=1 ORDER BY id DESC LIMIT 150 ;
