TRUNC (ADD_MONTHS(DATE, - CASE WHEN COUNTRYCODE='TH'
AND DATE >= (CURRENT_DATE+1)
THEN 6516 ELSE 0 END)
, 'day' ) as RDATE,
When you use TRUNC(DATE,'DAY') then it expected to display the date based on first day of week. Please refer link here where you can see below. That is the reason, you loose 2 to 6 days.
TRUNC(TO_DATE('22-AUG-03'), 'DAY')
Result: '17-AUG-03'

I am calculating the first week of every month for past 12 months from current date. The query logic that I am using is as follows:
SELECT
FORMAT_DATE('%Y%m%d', DATE_TRUNC(DATE_SUB(CURRENT_DATE(),interval 10 month), MONTH)) AS YYMMDD,
FORMAT_DATE('%Y%m', DATE_TRUNC(DATE_SUB(CURRENT_DATE(), interval 10 month), MONTH)) AS YYMM,
FORMAT_DATE('%Y%W', DATE_TRUNC(DATE_SUB(CURRENT_DATE(), interval 10 month), MONTH)) AS YYWW
OUTPUT:
Row
YYMMDD
YYMM
YYWW
1
20210101
202101
202100
The YYWW format returns the week as 00 and is causing my logic to fail. Is there anyway to handle this? My logic is going to be running 12 months calculation to find first week of every month.
At a very basic level, you can accomplish it with something like this:
with calendar as (
select date, extract(day from date) as day_of_month
from unnest(generate_date_array('2021-01-01',current_date(), interval 1 day)) date
)
select
date,
extract(month from date) as month_of_year,
case
when day_of_month < 8 then 1
when day_of_month < 15 then 2
when day_of_month < 22 then 3
when day_of_month < 29 then 4
else 5
end as week_of_month
from calendar
order by date
This approach is very simplistic, but you gave no criteria for your week-of-month definition in the query, so this is a reasonable answer. There is potential for a ton of variation in how you define week-of-month. The logic for week-of-year is built in to BQ, and provides options to handle items such as the starting day of the week, carryover at the end/beginning of consecutive years, etc. There is no corresponding week-of-month logic out of the box, so any "easy" built-in function like FORMAT_DATE() is unlikely to solve the problem.
I am looking for a SQL solution to work in Oracle Developer SQL that will calculate the current quarters start and end date based off of sysdate and that the Fiscal calendar starts on Feb 1, 2020. Each quarter is a Fixed 13 weeks (91 days) -- NOT 3 months, therefore each year has a slightly different fiscal calendar.
Code will be uploaded to automated reporting and do not want to adjust it each year.
Current year fiscal calendar attached as sample explanation.
Current Fiscal Calendar
I started to head down this road but got lost when i realized the start date wasnt able to be correct in this format.
End solution would be used for a where clause to determine reporting date range such as
( Where Report_Date between Modified_Quarter_Start and sysdate )
select trunc(add_months(add_months(trunc(sysdate,'Y') -1 ,
to_number(to_char(sysdate,'Q')) * 3),-1),'MM')
start_date,trunc(add_months(add_months(trunc(sysdate,'Y') -1 ,
to_number(to_char(sysdate,'Q')) * 3),+2),'MM')-1 Endd_date,
add_months(trunc(sysdate,'Y') -1 ,to_number(to_char(sysdate,'Q')) * 3) end_date ,
to_char(sysdate,'YYYY - q') qtr from dual
Greatly appreciate any assistance.
Posting incase someone else runs into the same predicement in the future.
After reading a mention of a case statement for fixed days in another thread, i thought of this solution.
Select Trunc(sysdate - to_date('02-Feb-2019')),
Case When Trunc(sysdate - to_date('02-Feb-2019')) > 91 Then to_date('02-Feb-2019') +
Round( to_number(Trunc(sysdate - to_date('02-Feb-2019'))/91),0) * 91
Else null End Current_Quarter_Start,
Case When Trunc(sysdate - to_date('02-Feb-2019')) > 91 Then to_date('02-Feb-2019') +
( (Round( to_number(Trunc(sysdate - to_date('02-Feb-2019'))/91),0) +1 )* 91)-1 Else null End Current_Quarter_End From Dual
How to get data of last 6 quarter in Oracle including current quarter. I mean if I run the query today so data between 01-JAN-2018 to 30-JUN-2019 should come in the query.
You could do something like this:
SELECT
*
FROM
DUAL
WHERE
DATE_FIELD >= (SYSDATE - (30*(3*6)))
What this query is doing is taking the current date (SYSDATE), and grabbing all values from the previous 6 quarters. The rationale is:
30 = days in a month | 3 = months in a quarter | 6 = quarters specified by OP
You can use add_months and trunc functions for date value with Q(quarter) argument
select t.*
from tab t
where insert_date between
trunc(add_months(sysdate,-3*5),'Q')
and trunc(add_months(sysdate,3),'Q')-1;
Demo for verification
for the starting date, -3*(6-1) = -3*5 considered, starting from 5 quarter back to be able to count 6 quarter including the current quarter. 3 is
obvious as being the number of months in each quarter.
i am trying to create a view that compares a SCHEDULE table that has values such as ('Daily', 'Wednesday', 'Tuesday', etc..) and another table (REPORT CREATED) that is updated every day with dates (11-AUG-2017). Basically, if the Schedule table shows Daily, then the Report Created table record value should be whatever sysdate (current date) is equal to. That said, I'm not sure how to find out what the most recent 'Wednesday' or 'Tuesday' is equal to. I did find a function for SQL server (How to get Saturday's Date (Or any other weekday's Date)- SQL Server) ; however, I do not understand how it works and can't find an equivalent in Oracle. Any guidance would be greatly appreciated!
Edit: I have created two sample tables:
Schedules Table:
Report_Name | Frequency
ORDERS_BY_DEPT | Daily
LOW_STOCK | Wednesday
INVENTORY_DISC | Thursday
and the Reports Table:
Report_Name | Create_Dt
INVENTORY_DISC | 3-Aug-2017
LOW_STOCK | 9-Aug-2017
ORDERS_BY_DEPT | 10-Aug-2017
So essentially, the Inventory_Disc report is off, since it should have ran every Thursday but hasn't been updated since last Thursday and the Orders_By_Dept report is off since it is a daily report and didn't run today.
Use the NEXT_DAY( date_value, day_string ) function. Take the current day (SYSDATE) and subtract 7 days from it and then find the next day which matches your required day-of-the-week.
So, to get the most recent Wednesday:
SELECT NEXT_DAY( TRUNC( SYSDATE ) - 7, 'WEDNESDAY' )
FROM DUAL
You can find the day of the week with:
to_char(sysdate, 'D')
So for example, the last Thursday is:
select case
when to_char(sysdate, 'D') < 4 then sysdate - to_char(sysdate, 'D') - 7 + 4
else sysdate - to_char(sysdate, 'D') + 4
end
from dual
Hi Ive been having an issue with getting the correct difference in a date from the current month not including the day.
ie if the month when the query is run is march 2013
then the following should be the result
EXECUTION_DATE, EXEC_DIFF
01-FEB-13, 1
31-JAN-13, 2
30-JAN-13, 2
however using the below sql statement im getting
EXECUTION_DATE, EXEC_DIFF
01-FEB-13, 1
31-JAN-13, 2
30-JAN-13, 1
select EXECUTION_DATE,
floor(MONTHS_BETWEEN (trunc(sysdate,'MM')-1, EXECUTION_DATE))+1 "EXEC_DIFF"
from V_CERT_LIST
WHERE EXECUTION_DATE < TO_DATE('02/02/2013','DD/MM/YYYY')
ORDER BY EXECUTION_DATE DESC
Please can someone put me right ive been bashing my head with this for some time now
thanks
select EXECUTION_DATE,
MONTHS_BETWEEN (trunc(sysdate,'MM'), trunc(EXECUTION_DATE,'MM')) "EXEC_DIFF"
from V_CERT_LIST
WHERE EXECUTION_DATE < TO_DATE('02/02/2013','DD/MM/YYYY')
ORDER BY EXECUTION_DATE DESC
Not looking for scores but cannot understand what is the problem with months_between? In my understanding it does not matter when in month execution takes place - Jan-31 or Jan 30... The difference is still 2 months between Jan and Mar as in your example. I can add more days in month in the query but mo_betw. will still be the same...:
SELECT to_char(exec_date, 'DD-MON-YYYY') exec_date, MONTHS_BETWEEN(run_date, exec_date) months_btwn
FROM
(
SELECT to_date('01/03/2013', 'DD/MM/YYYY') run_date
, Add_Months(Trunc(sysdate,'YEAR'),Level-1) exec_date -- first day of each month
FROM dual
CONNECT BY LEVEL <= 3
)
/
EXEC_DATE MONTHS_BTWN
------------------------
01-JAN-2013 2
01-FEB-2013 1
01-MAR-2013 0
Months_Between has complex logic that takes the day of the month into account.
Perhaps what you want is this:
select EXECUTION_DATE,
((year(sysdate)*12+month(sysdate)) - (year(execution_date)*12 + month(execution_date))
) as Exec_Diff
from V_CERT_LIST
WHERE EXECUTION_DATE < TO_DATE('02/02/2013','DD/MM/YYYY')
ORDER BY EXECUTION_DATE DESC
This converts the year/month combination into the number of months since 0 time and then subtracts the results.
