I wrote a simple query, it aggregates transaction amount on each user ID for every 3 days,
select user_id, sum(tran_amt) as tot_amt from transaction_table
where tran_dt>=cast('2016-12-31' as date) - INTERVAL '2' DAY
and tran_dt<='2016-12-31'
I want to calculate 3-day aggregated transaction amount for the whole month, from 12/01 to 12/31. I know how to do it in SAS, just replace the date '2016-12-31' with a macro variable, for example &tera_dt., something like this
%do i=1 %to 31;
call symput('tera_dt', "'"||put(intnx('day','1Jan2017'd,-&i,'b'),yymmdd10.)||"'")
But how can I create this date macro variable in Teradata? Thank you!
Or put it in another way, how to create a list of variables in Teradata? I want to create a macro variable called tera_dt, this variable contains dates from '2016-10-01' to '2016-10-31' total 31 dates, then I will run my query against this macro variable tera_dt. Thanks!
I don't think you need code generation for this problem. You can join with a query against the system view sys_calendar.calendar. Something like this:
select a.user_id
, b.calendar_date as date
, sum(a.tran_amt) as tot_amt
from transaction_table a
inner join
(select calendar_date from sys_calendar.calendar
where year_of_calendar=2016 and month_of_year=12) b
on a.tran_dt>=b.calendar_date - INTERVAL '2' DAY
and a.tran_dt<=b.calendar_date
group by 1,2

I have a temp table and I'm trying to sum data but can't seem to get the logic right for it. The table contains customer level data and now I'm trying to aggregate it by fiscal year, quarter, and product description. I'm trying to sum by going back 1 year and using the same quarter to sum the # of units sold.
I can do this in excel, but the table is too large for that. This is what the formula in Excel looks like:
=SUMIFS(Units,FiscalYearQuarter >= Concat(FiscalYear -1 & FiscalQuarter, FiscalYearQuarter <= Concat(FiscalYear, FiscalQuarter)
Here's an example of the table:
Here's what the results should looks like (This does not include productdescription, but I will want to add that in):
Every time I try to group by or do a Sum(Case When...) I keep getting the results only by the fiscal year/quarter instead of the sum of historical for 1 year.
A simple GROUP BY will work (although I don't quite understand your Excel logic with concatenation):
SELECT t1.FiscalYear, t1.FiscalQuater, sum(t2.UnitsPurchased)
FROM `table` t1
LEFT JOIN `table` t2
ON ( t1.FiscalYear = t2.FiscalYear + 1
AND t1.FiscalQuater < t2.FiscalQuater)
OR ( t1.FiscalYear = t2.FiscalYear
AND t1.FiscalQuater >= t2.FiscalQuater)
GROUP BY t1.FiscalYear, t1.FiscalQuater

I am using the Graph Reports for the select below. The MySQL database only has the active records in the database, so if no records are in the database from X hours till Y hours that select does not return anything. So in my case, I need that select return Paypal zero values as well even the no activity was in the database. And I do not understand how to use the UNION function or re-create select in order to get the zero values if nothing was recorded in the database in time interval. Could you please help?
select STR_TO_DATE ( DATE_FORMAT(`acctstarttime`,'%y-%m-%d %H'),'%y-%m-%d %H')
as '#date', count(*) as `Active Paid Accounts`
from radacct_history where `paymentmethod` = 'PayPal'
group by DATE_FORMAT(`#date`,'%y-%m-%d %H')
When I run the select the output is:
Current Output
But I need if there are no values between 2016-07-27 07:00:00 and 2016-07-28 11:00:00, then in every hour it should show zero active accounts Like that:
Needed output with no values every hour
I have created such select below , but it not put to every hour the zero value like i need. showing the big gap between the 12 Sep and 13 Sep anyway, but there should be the zero values every hour
(select STR_TO_DATE ( DATE_FORMAT(acctstarttime,'%y-%m-%d %H'),'%y-%m-%d %H')
as '#date', count(paymentmethod) as Active Paid Accounts
from radacct_history where paymentmethod <> 'PayPal'
group by DATE_FORMAT(#date,'%y-%m-%d %H'))
union ALL
(select STR_TO_DATE ( DATE_FORMAT(acctstarttime,'%y-%m-%d %H'),'%y-%m-%d %H')
as '#date', 0 as Active Paid Accounts
from radacct_history where paymentmethod <> 'PayPal'
group by DATE_FORMAT(#date,'%y-%m-%d %H')) ;
I guess, you want to return 0 if there is no matching rows in MySQL. Here is an example:
(SELECT Col1,Col2,Col3 FROM ExampleTable WHERE ID='1234')
UNION (SELECT 'Def Val' AS Col1,'none' AS Col2,'' AS Col3) LIMIT 1;
Updated the post: You are trying to retrieve data that aren't present in the table, I guess in reference to the output provided. So in this case, you have to maintain a date table to show the date that aren't in the table. Please refer to this and it's little bit tricky - SQL query that returns all dates not used in a table
You need an artificial table with all necessary time intervals. E.g. if you need daily data create a table and add all day dates e.g. start from 1970 till 2100.
Then you can use the table and LEFT JOIN your radacct_history. So for each desired interval you will have group item (group by should be based on the intervals table.
I am trying create a mysql query which will return the result only if like
Today's date is between 25th and end of the month.
I couldn't find a solution or idea how to go about it.
example:
SELECT m.member_name
FROM member m, `club_name` c
WHERE m.cabinet = 1 and c.wmmr_report=0 and m.club_name=c.id and date(curdate) between ...
Thanks
Actually you need only the day, not the whole date, so you may use
SELECT m.member_name
FROM member m, `club_name` c
WHERE m.cabinet = 1 and c.wmmr_report=0 and m.club_name=c.id and DAY(NOW()) >24
Date and Time Functions
I have a table with a list of tasks. Each task has a datetime field called "completedTime". Basically everytime a task is marked completed that field gets updated with the correct time.
Now I need to do a graph (using jQuery) for this result where the x axis is the months of the year (jan-dec) and the y axis is a number.
What is the sql query can I use so it would spit out 12 columns (Jan-Dec) with a number in each depending on how many tasks have a completedTime in that month.
I don't want to run the query below 12 times or each month.
SELECT * FROM `tasks` WHERE month(completedTime) between '02' and '03';
Any ideas?
If I understand correctly, your want it to return 12 rows (one for each month) with a count of the number of tasks.
If that is correct, then something like this should work. I added the year, which could be parametrized.
SELECT Count(*)
FROM Tasks
WHERE Year = 2011
GROUP BY Month(completedTime);
Revised with name for Month
SELECT Count(*) as total,
DateName(month, DateAdd(month, Month(completedTime), 0 ) - 1 ) as Month
FROM tasks
WHERE year(completedTime) = '2011'
GROUP BY Month(completedTime)
I'm not sure if this is even within the scope of MySQL to be honest or if some php is necessary here to parse the data. But if it is... some kind of stored procedure is likely necessary.
I have a table that stores rows with a timestamp and an amount.
My query is dynamic and will be searching based on a user-provided date range. I would like to retrieve the SUM() of the amounts for each day in a table that are between the date range. including a 0 if there are no entries for a given day
Something to the effect of...
SELECT
CASE
WHEN //there are entries present at a given date
THEN SUM(amount)
ELSE 0
END AS amountTotal,
//somehow select the day
FROM thisTableName T
WHERE T.timeStamp BETWEEN '$start' AND '$end'
GROUP BY //however I select the day
This is a two parter...
is there a way to select a section of a returned column? Like some kind of regex within mysql?
Is there a way to return the 0's for dates with no rows?
select * from thisTableName group by date(created_at);
In your case, it would be more like
SELECT id, count(id) as amountTotal
FROM thisTableName
WHERE timeStamp BETWEEN '$start' AND '$end'
GROUP BY DATE(timeStamp);
