I need to fetch last 2 months data in DB2 environment ,What is the query? The dates are changing ,so ,it must be dynamic.
If you want to get latest dates which are dynamically inserted then do something like below
select * from ur_table where urdate between (select max(urdate)- 2 months from urtable) and (select max(urdate) from urtable)

I am written a query which pulls work schedule data on person level in Oracle Fusion HCM. What is the filter or the join condition which I need to add to pull the latest date column.
I have used the tables
PER_SCHEDULE_ASSIGNMENTS PSA
, ZMM_SR_SCHEDULES_TL ZSST
, PER_ALL_ASSIGNMENTS_M PAAM
, PER_ALL_PEOPLE_F PAPF
The query returns 4 rows with different dates. How to return only 1 row which has the latest date column in it?
Use SYSDATE BETWEEN EFFECTIVE_START_DATE AND EFFECTIVE_END_DATE in all the tables where the date start date is there.
This will get you the current row as of today from those tables. You won't have any duplicates anymore.
I am creating a tableau dashboard and it should load data according to the date the user enters. This is the logic that I am trying.
select distinct XX.ACCOUNT_NUM, (A.TOTAL_BILLED_TOT-A.TOTAL_PAID_TOT)/1000 arrears, ((A.TOTAL_BILLED_TOT-A.TOTAL_PAID_TOT)/1000 - XX.SUM_BILL ) TILL_REF_JUL20
FROM
(
select /*+ parallel (bill ,40 ) */ distinct account_num, sum(INVOICE_NET_mny + INVOICE_TAX_mny)/1000 SUM_BILL
from bill
where account_num in (Select account_num from MyTable)
and trunc(bill_dtm) > ('07-Aug-2021') –-Refmonth+1 month and 07 is a constant. Only month and year is changing
and cancellation_dtm is null
group by account_num
)xx , account a
where xx.ACCOUNT_NUM = A.account_num
Here is what I tried. First created a parameter called ref_Month. Then created a calculated field with this.
[Ref_Month]=MAKEDATE(DATETRUNC('year',(DATEADD('month', 1, [Ref_Month])), 07))
But I am getting an error. I am using a live connection. Is there any method to achive this?
I don't understand what this statement is trying to do:
[Ref_Month]=MAKEDATE(DATETRUNC('year',(DATEADD('month', 1, [Ref_Month])), 07))
If Ref_Month is a date, which it has to be for DATEADD to be a valid operation, why not make it the 7th of whatever starting month and year you are starting with? Then DATEADD('month',1, [Ref_Month]) will be a month later, still on the 7th. So you don't need DATETRUNC or MAKEDATE at all.
That said, how, when, and where are you trying to COMPUTE a PARAMETER,
let alone based on itself?
I am select data from a table with different timestamps and I need to group the data by 7 days intervals without using the week keyword.
You can easily use the DAYS function and divide it by 7 like
GROUP BY DAYS(my_dt_column) / 7

I am using SQL Server 2008 R2. Here is the query I have that returns monthly sales totals by zip code, per store.
select
left(a.Zip, 5) as ZipCode,
s.Store,
datename(month,s.MovementDate) as TheMonth,
datepart(year,s.MovementDate) as TheYear,
datepart(mm,s.MovementDate) as MonthNum,
sum(s.Dollars) as Sales,
count(*) as [TxnCount],
count(distinct s.AccountNumber) as NumOfAccounts
from
dbo.DailySales s
inner join
dbo.Accounts a on a.AccountNumber = s.AccountNumber
where
s.SaleType = 3
and s.MovementDate > '1/1/2016'
and isnull(a.Zip, '') <> ''
group by
left(a.Zip, 5),
s.Store,
datename(month, s.MovementDate),
datepart(year, s.MovementDate),
datepart(mm, s.MovementDate)
Now I'd like to add columns that compare sales, TxnCount, and NumOfAccounts to the same month the previous year for each zip code and store. I also would like each zip code/store combo to have a record for every month in the range; so zeros if null.
I do have a calendar table that I tried to use to get all months, but I ran into problems because of my "where" statements.
I know that both of these issues (comparing to previous year and including all dates in a date range) have been asked and answered before, and I've gotten them to work before myself, but this particular one has me running in circles. Any help would be appreciated.
I hope this is clear enough.
Thanks,

Treat the Query you have above as a data source. Run it as a CTE for the period you want to report, plus the period - 12 months (to get the historic data). (SalesPerMonth)
Then do a query that gets all the months you need from your calendar table as another CTE. This is the reporting months, not the previous year. (MonthsToReport)
Get a list of every valid zip code / Store combo - probably a select distinct from the SalesPerMonth CTE this would give you only combos that have at least one sale in the period (or historical period - you probably also want ones that sold last year, but not this year). Another CTE - StoreZip
Finally, your main query cross joins the StoreZip results with the MonthsToReport - this gives you the one row per StoreZip/Month combos you are looking for. Left join twice to the SalesPerMonth data, once for the month, once for the 1 year previous data. Use ISNULL to change any null records (no data) to zero.
Instead of CTEs, you could also do it as separate queries, storing the results in Temp tables instead. This may work better for large amounts of data.
This might be a simple one but I haven't got a solution yet. I have a create_date field which is a date type, and a revenue number. I want to see weekly break down of revenue.
I can get the numbers easily in tableau because of built in functionality but doing it in PostgreSQL is where I need some help.
If you want the revenue by week, you'll need to group and aggregate:
select extract (week from create_date) as week, sum(revenue) from table group by week
