I have a table with datetime like this:
2018-08-08 00:00:00
2018-08-08 03:00:00
2018-08-08 06:00:00
2018-08-08 09:00:00
2018-08-08 12:00:00
2018-08-08 15:00:00
2018-08-08 18:00:00
2018-08-08 21:00:00
2018-08-09 00:00:00
2018-08-09 03:00:00
2018-08-09 06:00:00
2018-08-09 09:00:00
2018-08-09 12:00:00
I search for rows between CURDATE() + INTERVAL 1 DAY and CURDATE() + INTERVAL 4 DAY, but also only at 06:00:00 and 12:00:00.
How can I select this hours?

You can use time() to extract the time.
...
WHERE ...
AND time(nmuloc) BETWEEN time '6:00:00'
AND time '12:00:00'

SELECT * FROM `shifts` WHERE user_id = 1 order by team_id, date, start_time;

This isn't an "answer" but I need formatting to make a point:
Please check your expected result. I assume "value" means the rows are related, and that for any sequence the first row cannot produce a result
e.g.
Rowid Date Value Interval_gap
1 01-Nov-16 00:00:00 716 NULL << nothing prior to this row, so no calculation
2 01-Nov-16 00:15:00 716 15 mins
3 01-Nov-16 00:15:00 716 0 mins
5 01-Nov-16 01:00:00 716 45 mins
6 01-Nov-16 01:00:00 34 NULL << nothing prior to this row, so no calculation
7 01-Nov-16 02:00:00 66 NULL << nothing prior to this row, so no calculation
4 01-Nov-16 00:45:00 717 NULL << nothing prior to this row, so no calculation
8 01-Nov-16 03:00:00 717 2 Hours 45 mins
9 01-Nov-16 04:00:00 717 1 hour
10 01-Nov-16 05:00:00 717 1 hour

I'd like to extract the start and end timestamps where readings go above 50 and below 50, respectively. I just can't get my head around the SQL presented in the other answer!
Thanks in advance for your help.
If it only goes below/above again once per day, you can make the query quite simple; just find the min and max time where it's below, grouping by date.
SELECT
DATE(statustime) statusdate,
MIN(CASE WHEN reading<50 THEN statustime ELSE NULL END) start_time,
MAX(CASE WHEN reading<50 THEN statustime ELSE NULL END) end_time
FROM myTable
GROUP BY statusdate
An SQLfiddle to test with.
Try this code:
select *
(select max(StatusTime) from tbl where Reading > 50) above_50,
(select min(StatusTime) from tbl where Reading < 50) bellow_50;
Something like this?
SELECT DISTINCT MAX(StatusTime), MIN(StatusTime)
FROM table_name
WHERE Reading < 50 OR Reading > 50;
I got time-series data storing in a table as follows.
id, timestamp, value
d1 2000-01-01 00:00:00 1
d1 2000-01-01 01:00:00 2
d1 2000-01-01 02:00:00 3

d3 2000-01-01 03:00:00 52
d3 2000-01-01 04:00:00 53
What I need to do is to add another column to the table as follows.
The purpose is to label the number of data points for each id for further process.
id, timestamp, value, counter
d1 2000-01-01 00:00:00 1 1
d1 2000-01-01 01:00:00 2 2
