I'm using the below MySQL found on the web to generate a list of dates.
However, I want it to generate a list of date_times by minute, E.G yyyy-mm-dd hh:mm:ss.
Is this possible? I can't wrap my head around how the existing SQL generates the list nevermind adding minutes!
I need this for my base query for a chart / graph, using left join to pull in data from elsewhere.
Thanks
select * from
(select adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) selected_date from
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
where selected_date between '2019-01-01' and '2019-01-15'
Current output:
selected_date
---
2019-01-01
2019-01-02
2019-01-03
2019-01-04
Desired output:
selected_date

2019-01-19 00:10:00
2019-01-19 00:11:00
Edit:
This is my SQL query serving the graph. I get 5-6 temperature records per minute, so I'm averaging them.
My problem is sometimes a temperature probe drops off, so a.date_time or b.date_time doesn't have a consecutive date_time for every single minute
select
b.date_time,
a.temperature as fishtank,
b.temperature as room
from (
select
serial,
convert((min(date_time) div 100)*100, datetime) as date_time,
avg(temperature) as temperature
from
raspicontroller.temperature
WHERE
date_time between '$date_from' and '$date_to' and
serial like '28-000898430d59'
group by
date_time div 100
) a
right join (
select
serial,
convert((min(date_time) div 100)*100, datetime) as date_time,
avg(temperature) as temperature
from
raspicontroller.temperature
WHERE
date_time between '$date_from' and '$date_to' and
serial like '28-000f9843201e'
group by
date_time div 100
) b on a.date_time = b.date_time
Edit again:
I've not managed to generate what I wanted, however I've come up with this which uses existing values in the DB to list dates. I think this will work for me
SELECT
a.date_time,
b.temperature as FishTank,
c.temperature as Room
FROM (
select
convert((min(date_time) div 100)*100, datetime) as date_time
from
raspicontroller.temperature
group by
date_time div 100
) as a
LEFT JOIN (
select
serial,
convert((min(date_time) div 100)*100, datetime) as date_time,
avg(temperature) as temperature
from
raspicontroller.temperature
WHERE
serial like '28-000898430d59'
group by
date_time div 100
) as b on a.date_time = b.date_time
LEFT JOIN (
select
serial,
convert((min(date_time) div 100)*100, datetime) as date_time,
avg(temperature) as temperature
from
raspicontroller.temperature
WHERE
serial like '28-000f9843201e'
group by
date_time div 100
) as c on a.date_time = c.date_time

Problem
I want to show all users for a specific range lets say from 2020-01-01 to from 2020-01-05.
I have a table user where all users are saved. Imagine following table:
user
id | createdAt
1 2020-01-01
2 2020-01-02
3 2020-01-03
4 2020-01-03
5 2020-01-05
The outcome should be (relating to the above user table):
date | count
2020-01-01 1
2020-01-02 2
2020-01-03 4
2020-01-04 4
2020-01-05 5
What I have so far
I have a query that returns the example above as needed:
SELECT COALESCE((SELECT COUNT(*) FROM user u WHERE DATE(u.createdAt) <= DATE(dates.gen_date) AND u.role = 'USER' GROUP BY dates.gen_date ),0) AS y, dates.gen_date AS x FROM user u, (select * from
(select adddate('1970-01-01',t4*10000 + t3*1000 + t2*100 + t1*10 + t0) gen_date from
(select 0 t0 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 t1 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 t2 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 t3 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(select 0 t4 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
where gen_date between DATE(?) and DATE(?)) AS dates GROUP BY x;
But the execution of this statement is really slow by huge number of users and a large time range.
I thought also of a materialized view but this would be only the last way out.
Database used: MySql 5.7
Test
SELECT (dates.mindate + INTERVAL (t0.n+10*t1.n+100*t2.n+1000*t3.n) DAY) `date`,
COUNT(users.id) `count`
FROM users,
(SELECT ? mindate, ? maxdate) dates,
(select 0 n union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 n union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 n union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 n union select 1 union select 2) t3
WHERE users.createdAt <= (dates.mindate + INTERVAL (t0.n+10*t1.n+100*t2.n+1000*t3.n) DAY)
GROUP BY `date`
HAVING `date` <= dates.maxdate
ORDER BY `date`
It must be less expensive.
I have a table which contains two columns: date, and revenues generated in this date, however, if no revenues were generated at a certain date, this date will not show in the table, what I want is to show this date with 0 as revenue.
I tried a query that generates a list of dates between two dates, however, I couldn't find how to left join this query with my table since this date generator query has no id.
this is my table query:
SELECT CAST(insertDate AS DATE) AS DATE,
SUM(timeofcall)*10 as total_Revenue_Generated_from_CallBacks
FROM callcompletion.tbl_calltracking
GROUP BY CAST(insertDate AS DATE);
results->
DATE total_Revenue_Generated_from_CallBacks
2019-10-14 2200
2019-10-15 44000
2019-10-16 4400
2019-10-17 8800
2019-10-24 12100
and this is the date generator query:
SELECT selected_date FROM (
SELECT adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) selected_date
from
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,

) v
WHERE selected_date BETWEEN '2019-10-14' AND '2019-10-24'
results->

You need to decide what is the minimum and maximum date you wish to show. In addition to that, you can simply join the generated dates with your original query:
SELECT d.selected_date AS DATE, ifnull(SUM(c.timeofcall)*10,0) as total_Revenue_Generated_from_CallBacks
FROM (
SELECT adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) selected_date
FROM
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(SELECT 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4
) as d
left join callcompletion.tbl_calltracking c on CAST(c.insertDate AS DATE) = d.selected_date
WHERE d.selected_date between '2019-10-14' and '2019-10-24'
GROUP BY d.selected_date;
See DB-Fiddle
Currently having a little difficulty with respect to getting a list of dates.
I currently have the following SQL:
SELECT DISTINCT DATE(startDate) activity_date
, CASE WHEN (DATE(endDate) - DATE(startDate)) > 0 THEN DATE(endDate) ELSE FALSE END multiEvent
FROM activities
WHERE startdate BETWEEN '2017-08-01' AND '2017-08-31'
AND accountid = 578
ORDER
BY DATE(startdate)
Which gives the following result:
activity_date | multiEvent
2017-08-07 | 0
2017-08-07 | 2017-08-10
2017-08-18 | 0
However, what i am trying to achieve is, if multiEvent is not zero, then list the dates between the dates of activity_date & multiEvent into a single column.
Result I am trying to achieve:
activity_date |
2017-08-07 |
2017-08-07 |
2017-08-08 |
2017-08-09 |
2017-08-10 |
2017-08-18 |
ideas? :)
You need to first find a way to create rows for dates between activity_date and multiEvent. This query will produce the intended resultset of dates, as individual rows.
select date(eachDate) as eachDate from
(select adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) as eachDate
from
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) as v
where
eachDate between date('2017-08-07')
and date('2017-08-10') order by eachDate asc ;
This will produce a result like
eachDate
2017-08-07
2017-08-08
2017-08-09
2017-08-10
Now, we need to fit in the above query with your existing query to get the intended output. The query would look something like this.
select
activity_date
from
(select
date(startDate) as activity_date
from
activities
where
startdate between date('2017-08-01') and date('2017-08-31')
and accountid = 578
and NOT (DATE(endDate) - DATE(startDate)) > 0
union all
select
eachDate
from
(select date(eachDate) as eachDate
from
(select adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) as eachDate
from
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) as v
where
eachDate between date('2017-08-01')
and date('2017-08-31')) as dates_table
join
(select
date(startDate) as startDate,
date(endDate) as endDate
from
activities
where
startdate between date('2017-08-01') and date('2017-08-31')
and accountid = 578
and (date(endDate) - date(startDate)) > 0 ) as activities_table
on dates_table.eachDate between activities_table.startDate and activities_table.endDate) as main
order by
main.activity_date asc;
and the output looks like this.
activity_date
2017-08-07
2017-08-07
2017-08-08
2017-08-09

I have a date range parameter, need to split into multiple date, and each will have same time as the parameter.
Not sure what is the problem with ADDTIME, maybe Im missing a cast? I can solve it casting to string and concat but I guess should be easier.

and now i want to get all the dates between from date and to date.
Expected output

from (
select curdate() - INTERVAL (a.a + (10 * b.a) + (100 * c.a)) DAY as Date
from (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as a
cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as b
cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as c
) a

First, I don't know your specific use case, but this feels ripe for more optimization. However, how about this?
select * from
(select adddate('1970-01-01',t4*10000 + t3*1000 + t2*100 + t1*10 + t0) selected_date from
(select 0 t0 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
(select 0 t1 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
(select 0 t2 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
(select 0 t3 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
(select 0 t4 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
where (selected_date between '2012-02-10' and '2012-02-15') OR
(selected_date between '2012-03-10' and '2012-03-15') OR
(selected_date between '2012-04-10' and '2012-04-15')
