Hi
I need your help
the day was divided into four time slots
00:00:00-06:00:00
06:00:00-12:00:00
12:00:00-18:00:00
18:00:00-24:00:00for each of these time slots I need to search the rows in the database table MySQL between for start hour and end hour
21:00:00-09:00:00
03:00:00-15:00:00
09:00:00-21:00:00
15:00:00-03:00:00that is
(-3h) 00:00:00-06:00:00 (+3h)
(-3h) 06:00:00-12:00:00 (+3h)
(-3h) 12:00:00-18:00:00 (+3h)
(-3h) 18:00:00-24:00:00 (+3h)the `xtable` is truncated each day and recompile with only the events of previous day
I'v tried this query for time slot `(-3h) 18:00:00-24:00:00 (+3h)`
mysql> SELECT * FROM `xtable` WHERE
xDate IN ('2020-05-20')
AND (
xHourMinute >= '15:00:00'
OR xHourMinute <= '03:00:00'
);+----------+------------+-------------+----+

16 rows in setBut the return is wrong because they were extracted these row which are the ones with date `2020-05-20` and not `2020-05-21` remember `24:00:00 (+3h)` this is the next day...
