I am trying to retrieve last 3 months records. I need to sum order total amount by week. I have made following query.
select CONCAT("Week", WEEK(created_at)) as week_number, sum(total_cost)
from certified_diamond_orders
where created_at > 2016-11-22
and status = "delivered"
group by week("created_at")
But I am only getting one record with this. Infact my table has 2 years entries. Also I was trying to figure out how I can pull week start date and end date to diplay on my chart.
Any suggestions where I am making mistake?
week("created_at") looks like you're trying to determine the week of the string "created_at" rather than the column created_at. Which might explain why you're only getting one row in your result.
The date 2016-11-22 also looks suspiciously like a sum instead of a date (2016 - 11 - 22 = 1983 vs "2016-11-22"
Try this:
SELECT
CONCAT('Week', WEEK(created_at)) AS week_number,
SUM(total_cost)
FROM certified_diamond_orders
WHERE
created_at > '2016-11-22' AND
status = 'delivered'
GROUP BY WEEK(created_at)

Hi Everyone i am writing mysql query for getting current week and last week data in same table with different rows expected output i have mention below also i need last week data based on current week selection. current week data i am getting based on select date but didn't know how to get last week date, please help me out.
date
total_cars
online_hours
trips
current_week
20
100
200
last_week
10
60
80
query for current week record
SELECT cd.date, COUNT( cd.car_number) as total_cars, sum(cd.trips) as total_trips,
sum(cd.online_hours) as online_hours
FROM fleet_car_dash_daily as cd
WHERE cd.team_id= 1 and cd.date BETWEEN '2022-04-04' and '2022-04-10'
This can also help:
SELECT cd.date, COUNT( cd.car_number) as total_cars, sum(cd.trips) as total_trips,
sum(cd.online_hours) as online_hours
FROM fleet_car_dash_daily as cd
WHERE cd.team_id= 1 and cd.date BETWEEN '2022-04-04' - INTERVAL 7 DAY and '2022-04-10'
GROUP BY WEEK(cd.date)
ORDER BY WEEK(cd.date);
I'm in need of some help structuring in-time queries. There's a few of them I need - but I think that if I can be shown how to do one, I can figure out the others.
What I'm after:
-Rolling 12 month view of 'inactive accounts'...ie number of accounts that have not placed an order in the 12 months prior.
-This ideally will be a subquery (in a much larger script) joining back on to a dates table (see below)
January 2015 | # of customers with no orders from 1/2014-1/2015
February 2015 | # of customers with no orders from 2/2014-2/2015
March 2015 | # of customers with no orders from 3/2014-3/2015
etc...
What I'm having trouble wrapping my mind around is how I'd structure a where clause to ensure that it scans all orders and only returns the total of account ID's that had not placed an order in the year prior to that month. I've used different combinations of DATEDIFF, DATESUB etc.
SELECT DATE_FORMAT(order_datetime, '%Y-%m'), COUNT DISTINCT (account_id)
FROM warehouse.orders
JOIN warehouse.accounts ON xyz
WHERE...
It feels like I'm on the right path - I just keep mentally going in circles trying to figure this out.
Cheers and thanks in advance.
I don't have enough reputation points to simply comment on your question. I don't fully understand it though.
Are you using SQLServer/TSQL or MySQL?
Do you want to have just one column which calculates the last 12 months' rolling average or 12 columns for the rolling average each month? If it is just one figures for the last 12 months tolling do you want that to be from the current day or the beginning of that month?
If it was SQL Server and a rolling 12 months to now, the calculation could be:
SELECT SUM(CASE WHEN DATEDIFF(y,GETDATE(),order_date_time) < 1 THEN COUNT(DISTINCT account_id) END) as January2015
If you're using MySQL replace GETDATE() with NOW()
If you want one value rolling but to the beginning of the month then you could use:
SELECT SUM(CASE WHEN DATEDIFF(y,DATEADD(M, DATEDIFF(M, 0, GETDATE()), 0),order_date_time) < 1 THEN COUNT(DISTINCT account_id) END) as January2015
If I've missed the point entirely, please let me know and I'll happily amend the answer
You should query between dates, in order to get the count of events for each id.
select case
when count(account_id)<0 then 'INACTIVE'
when count(account_id)>0 then 'ACTIVE'
from warehouse.orders
where data_format(order_datetime, '%m/%Y') between '1/2014' and '1/2015'
group by account_id)
I need to get the row where the due_date field has the last month in every year.
For eg: if I have 3 entries with due_date field like 2014-5-21,2014-6-21,2014-7-21
I need the last row in year 2014, that will be 2014-7-21, like wise in 2015 and the following years.
Can someone help me out with this.
I tried but nothing worked out
SELECT distinct(year(due_date)) FROM `vw_mortgage_repayment_schedule_org`
where mortgage_id ='AREM-1408614735-VLASFAQ8VI'
and month(due_date) = max(month())
I need all the last rows for the given mortgage of every year eg- 2014,2015,2016 etc
I think if you group by the year of the due_date, that might just about give you what you need, given that we search for the max month in the select, and group by the year. Possibly. Can we have your table structure?
SELECT year(due_date), month(max(due_date)), max(due_date)
FROM `vw_mortgage_repayment_schedule_org`
where mortgage_id ='AREM-1408614735-VLASFAQ8VI'
GROUP BY year(due_date)
There is a table Post in my database which contains posts of different users. What I wanna do is to create an sql query that'll return as per respective month the number of posts being made each day. Kindly let me know how can i do that generically in one query i can create multiple queries for all days but that is a worst case scenario. So I need expert's solution to this.
Thanks
Expected output:
(Query counts the number of posts for all the days in a respective month)
Day : Number of posts
1 : 20
2 : 25
3 : 10
4 : 17
.........................
30 : 6
Table Structure:
ID | postid | post | date
select DAYOFMONTH(date) as Day , count(*) as Number_of_posts
from table
group by DAYOFMONTH(date)
You should know that if table contains data from different months number of posts will be wrong.
So the group by should be by date and you should use date in selected instead of day of month.
SELECT DAYOFMONTH(date), count(*) FROM Post
GROUP BY DAYOFMONTH(date)
ORDER BY DAYOFMONTH(date) ASC;
If you want to query for a specific month (say, February) then use this:
SELECT DAYOFMONTH(date), count(*) FROM Post
WHERE MONTH(date) = '2'
GROUP BY DAYOFMONTH(date)
ORDER BY DAYOFMONTH(date) ASC;
Note: Months are returned in number form where the MONTH() function is used.
EDIT: If you're looking to return counts for EVERY day in a given month, then I'd push you here - a great accepted answer to a similar question: How to get values for every day in a month
SELECT date, COUNT(id) as number_of_posts FROM table_name GROUP BY date.
I have some data which I want to retrieve, but I want to have it grouped by a specific number of seconds. For example if my table looks like this:
| id | user | pass | created |
The created column is INT and holds a timestamp (number of seconds from 1970).
I would want the number of users that are created between last month and the current date, but show them grouped by let's say 7*24*3600 (a week). So if in the range there are 1000 new users, have them show up how many registered each week (100 the first week, 450 the second, 50 the third and 400 the 4th week -- something like this).
I've tried grouping the results by created / 7*24*3600, but that's not working.
How should my query look like?
You need to use integer division div otherwise the result will turn into a real and none of the weeks will resolve to the same value.
SELECT
(created div (7*24*60*60)) as weeknumber
, count(*) as NewUserCount
FROM users
WHERE weeknumber > 1
GROUP BY weeknumber
See: http://dev.mysql.com/doc/refman/5.0/en/arithmetic-functions.html
You've got to keep the integer part only of that division. You can do it with the floor() function.
Have you tried select floor(created/604800) as week_no, count(*) from users group by floor(created/604800) ?
I assume you've got the "select users created in the last month" part sorted out.
Okay here are the possible options you may try:
GROUP BY DAY
select count(*), DATE_FORMAT(created_at,"%Y-%m-%d") as created_day FROM widgets GROUP BY created_day
GROUP BY MONTH
select count(*), DATE_FORMAT(created_at,"%Y-%m") as created_month FROM widgets GROUP BY created_month
GROUP BY YEAR
select count(*), DATE_FORMAT(created_at,"%Y") as created_year FROM widgets GROUP BY created_year
