I have a requirement to display dates every week starting from current date for 48 months.
I was wondering if it is possible through SQL or i will have to write a function to achieve it.
Below is my SQL so far :-
SELECT
CALENDAR_DATE
FROM
CALENDAR --My Table Name
WHERE
(
CALENDAR_DATE >= trunc(sysdate)
AND
CALENDAR_DATE <= ADD_MONTHS(TRUNC(SYSDATE, 'MONTH'), 48)-1
)
This would give me output as
9/10/2020
9/11/2020
9/12/2020
9/13/2020
Expected Output :-
9/10/2020
9/17/2020
9/24/2020
10/01/2020
If I understand correctly:
WHERE CALENDAR_DATE >= trunc(sysdate) AND
CALENDAR_DATE <= ADD_MONTHS(TRUNC(SYSDATE, 'MONTH'), 48) - 1 AND
MOD(CALENDAR_DATE - TRUNC(sysdate), 7) = 0
This uses the mod() operation on the date difference. You can also check the day of the week:
WHERE CALENDAR_DATE >= trunc(sysdate) AND
CALENDAR_DATE <= ADD_MONTHS(TRUNC(SYSDATE, 'MONTH'), 48) - 1 AND
TO_CHAR(CALENDAR_DATE, 'DY') = TO_CHAR(sysdate, 'DY')

i have a query
select count(1) z1
from sales_data
where ed_date >= sysdate -7
i need to group by ed
_date, remove the timestamp, and condition where ed_date is from 1/1/2021 to current sysdate
You can truncate the date:
select trunc(ed_date, 'DD') as ed_date, count(*) as z1
from sales_data
where ed_date >= date '2021-01-01'
and ed_date < trunc(sysdate, 'DD')
group by trunc(ed_date, 'DD')
The 'DD' truncation limit is the default so you could omit that, as just trunc(ed_date), if you prefer. Note though that it doesn't remove the time, it just sets it to midnight - an Oracle date always has both date and time components.
You can also order by trunc(ed_date), and in the select list you can format that however you want:
select to_char(trunc(ed_date), MM/DD/YYYY') as ed_date, count(*) as z1
from sales_data
where ed_date >= date '2021-01-01'
and ed_date < trunc(sysdate) -- to exclude today and future
-- and ed_date < trunc(sysdate) + 1 -- to include today but not tomorrow onwards
group by trunc(ed_date)
order by trunc(ed_date)
For the query below, I'm trying to pull a specific date range depending on the current day of the month. If it's the 20th or less (e.g. "2/7/2020") then I want the date range for January. Otherwise, I want the date range for February. Is it possible to be done with a case statement? Or there is a better way?
SELECT
account,
start_date,
amount
FROM
table1
WHERE
CASE
WHEN (
SELECT
CAST(EXTRACT(DAY FROM sysdate) AS NUMBER)
FROM
dual
) <= 20 THEN
start_date
BETWEEN '2020-01-01' AND '2020-01-31'
ELSE start_date BETWEEN '2020-02-01' AND '2020-02-29'
END
You can do this by avoiding the case statement and using truncate the date - 20 to the month, e.g.:
SELECT account,
start_date,
amount
FROM table1
WHERE start_date >= TRUNC(SYSDATE - 20, 'mm')
AND start_date < add_months(TRUNC(dt - 20, 'mm'), 1);
If you really had to use a CASE expression (you can't use a CASE statement in SQL), you would need to do something like:
SELECT account,
start_date,
amount
FROM table1
WHERE start_date >= CASE WHEN to_char(SYSDATE, 'dd') <= '20' THEN add_months(TRUNC(SYSDATE, 'mm'), -1) ELSE TRUNC(SYSDATE, 'mm') END
AND start_date < CASE WHEN to_char(SYSDATE, 'dd') <= '20' THEN TRUNC(SYSDATE, 'mm') ELSE add_months(TRUNC(SYSDATE, 'mm'), 1) END;
N.B. if you're using a function, you don't need to wrap it in a select .. from dual, you can use it directly in the SQL statement.
I've also assumed that you want a dynamic range, e.g. if the day of the month is 20 or less, the range is for the previous month, otherwise the current month.
ETA: You would use the above two queries if there is an index on the start_date column, otherwise you could simply do:
SELECT account,
start_date,
amount
FROM table1
WHERE TRUNC(start_date, 'mm') = TRUNC(SYSDATE - 20, 'mm');
Case statements return single values. As such you should pull out the start date and you'll need two case statements.
select account, start_date, amount
from table1 where
start_date between
(case
when (select cast(extract(day from sysdate) as number) from dual) <= 20 then '2020-01-01'
else '2020-02-01'
end) and
(case
when (select cast(extract(day from sysdate) as number) from dual) <= 20 then '2020-01-31'
else '2020-02-29'
end)
One method subtracts 20 days and then gets the month boundary:
where start_date >= trunc(sysdate - interval '20' day, 'MON') and
start_date < trunc(sysdate - interval '20' day, 'MON') + interval '1' month
This approach is index (and partition) friendly -- an appropriate index on start_date can be used. It is also safe if start_date has time components.
Note: You can use sysdate without having to use a subquery.
You can use or operator with last_day function as following:
Select * from your_table
Where (
start_date <= trunc(sysdate,'mm') + 20
and start_date between trunc(sysdate,'mm') - interval '1' month and trunc(sysdate,'mm') - 1
)
Or
(
start_date > trunc(sysdate,'mm') + 20
and start_date between trunc(sysdate, 'mm') and last_day(sysdate)
)
This approach will use index on start_date, if any.
Cheers!!
select account, amount, start_date
from table1
where ( ( (select cast (extract (day from sysdate) as number) from dual) <= 20
and start_date between date '2020-01-01' and date '2020-01-31')
or ( (select cast (extract (day from sysdate) as number) from dual) > 20
and start_date between date '2020-02-01' and date '2020-02-29')
);
Using CASE expressions as BETWEEN operands:
SELECT account
, start_date
, amount
FROM table1
WHERE start_date BETWEEN CASE
WHEN extract(day from sysdate) <= 20
THEN trunc(sysdate -interval '1' month, 'month')
ELSE trunc(sysdate, 'month')
END
AND CASE
WHEN extract(day from sysdate) <= 20
THEN last_day(sysdate -interval '1' month)
ELSE last_day(sysdate)
END
how to get current month to date values in oracle 12c sql developer
Select dcc.EMPLOYEECODE, dcc.DUTYID, dtt.DUTYDESC
from DUTYCHART dcc
join DCDUTYCHART dtt
on dcc.RESTCODE = dtt.RESTCODE
and dcc.DUTYID = dtt.DUTYID
and trunc(date) = trunc(sysdate)
Here am getting current date but I want to show current month and previous month, I tried some functions like add-months but it didn't worked for me
You can use :
trunc(sysdate, 'MONTH') -- CURRENT MONTH START DATE
ADD_MONTHS(trunc(sysdate, 'MONTH'), -1) -- PREVIOS MONTH START DATE
If you want to get data of previous month then your query's where clause must include: Replace (trunc(date) = trunc(sysdate)) with one of the following according to your need
trunc(date) BETWEEN ADD_MONTHS(trunc(sysdate, 'MONTH'), -1)
AND trunc(sysdate, 'MONTH') - 1 -- PREVIOUS MONTH'S DATA
trunc(date) >= trunc(sysdate, 'MONTH') -- -- CURRENT MONTH'S DATA
trunc(date) >= ADD_MONTHS(trunc(sysdate, 'MONTH'), -1) -- PREVIOUS AND CURRENT MONTH'S DATA TOGETHER
Cheers!!
For the current month, use:
date >= trunc(sysdate, 'MONTH')
For the previous month, use:
(date >= trunc(sysdate, 'MONTH') - interval '1' month and
date < trunc(sysdate, 'MONTH')
)
There is no reason to truncate date for the comparison.
Select *
From Orders
WHERE (
extract(day from sysdate)<=21
and
to_date(SCHEDULEDATE , 'yyyy/mm/dd') between
to_date((to_char(sysdate, 'YYYY')||'/'||cast((extract(month from sysdate)-1)as char)||'/22'),'yyyy/mm/dd') and to_date((to_char(sysdate,'YYYY')||'/'||cast((extract(month from sysdate))as char)||'/21'),'yyyy/mm/dd')
)
or
(
extract(day from sysdate)>21
and
to_date(SCHEDULEDATE , 'yyyy/mm/dd') between
to_date((to_char(sysdate, 'YYYY')||'/'||cast((extract(month from sysdate))as char)||'/22'),'yyyy/mm/dd') and to_date((to_char(sysdate, 'YYYY')||'/'||cast((extract(month from sysdate)+1)as char)||'/21'),'yyyy/mm/dd')
)
I'm trying to figure out a simple way of returning a set of date ranges based on the day of the Month. If the Day of the month of less than or Equal to I want it to return all orders the have a schedule date between the 22 of the Month before and the 21st of the Current month. If the Day of the month is greater than 21 I would like it return all orders that have a schedule date of the current month up to the end of the month. I've tried to use a case in the where with no luck. What I have now doesn't seem to work either. Any help would be appreciated.
I think this does what you want:
WHERE (extract(day from sysdate) <= 21 and
scheduledate >= add_months(trunc(sysdate, 'MON'), -1) + 21 and
scheduledate < trunc(sysdate, 'MON') + 21
) or
(extract(day from sysdate) > 21 and
trunc(scheduledate, 'MON') = trunc(sysdate, 'MON')
)
I can't seem to find a straightforward sql without delving into PL SQL for always bringing current financial year in which case 01-04-2015 to sysdate. I want this to always update automatically so when it comes next financial year in 01/04/2016 it will bring whatever is held from that date to whenever the report is being run.
If anyone can please shed some light for me. thanks
sql is:
SELECT
PROPERTY.PRO_MANAGINGCOMPANY_DESCR,
PROPERTY.PRO_SCHEME_DESCR,
PROPERTY.PRO_SCHEME,
SUM(REPAIR_CURRENT.REP_ESTIMATED_COST) as "Estimated Cost",
nvl(SUM(REPAIR_CURRENT.REP_INVOICED_COST),SUM(REPAIR_CURRENT.REP_ESTIMATED_COST)) as "Estimated Cost Invoiced",
SUM(REPAIR_CURRENT.REP_INVOICED_COST) as "Invoice Cost",
to_char(REPAIR_CURRENT.REP_RAISED_DATE,'Mon') as "Month",
to_number(to_char(to_date(REPAIR_CURRENT.REP_RAISED_DATE,'dd-mon-yy'),'mm')) as "Month No."

If you just want to get the beginning of the fiscal year for the current date:
SELECT TO_DATE('01-04' || CASE
WHEN EXTRACT(MONTH FROM SYSDATE) > 4 THEN
EXTRACT(YEAR FROM SYSDATE)
ELSE
EXTRACT(YEAR FROM SYSDATE)-1
END, 'DD-MM-RRRR') FISCAL_YEAR
FROM DUAL
This works for any date:
REPAIR_CURRENT.REP_RAISED_DATE
BETWEEN Add_Months(Trunc(Add_Months(sysdate,-3),'YYYY'),3)
AND Sysdate
Basically, subtract three months, truncate to the year, and add three months back on.
To just get the financial year for a date, use:
Extract(Year from Add_Months(Trunc(Add_Months(sysdate,-3),'YYYY'),3))
SELECT *
FROM your_table
WHERE datetime >= CASE
WHEN SYSDATE < TRUNC( SYSDATE, 'YEAR' ) + INTERVAL '3' MONTH
THEN TRUNC( SYSDATE, 'YEAR' ) - INTERVAL '9' MONTH
ELSE TRUNC( SYSDATE, 'YEAR' ) + INTERVAL '3' MONTH
END;
Thank you, the following worked! add_months(trunc(sysdate,'year'),3) AND sysdate
thank you all for your input :)
REPAIR_CURRENT.REP_RAISED_DATE BETWEEN '01-APR-2015' AND sysdate
Firstly, '01-APR-2015' is not a DATE it is a string. You must always use TO_DATE along with proper format model to explicitly convert the string into DATE. Or, use the ANSI Date literal as you are not concerned with the time portion. It uses a fixed format 'YYYY-MM-DD'.
Now, coming to your date arithmetic, you could use a CASE expression to evaluate the financial date depending on the year.
REP_RAISED_DATE
BETWEEN
CASE
WHEN
SYSDATE < ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 3)
THEN
ADD_MONTHS(TRUNC(SYSDATE, 'YEAR') , -9)
ELSE
ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 3)
END
AND SYSDATE
Basically, SYSDATE >= ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 3) is to check whether SYSDATE is greater than 1-APR of current year. And, SYSDATE < ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 15) is to check whether it is between JAN and MARCH of next year.
For example,
SQL> SELECT
2 CASE
3 WHEN
4 SYSDATE < ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 3)
5 THEN
6 ADD_MONTHS(TRUNC(SYSDATE, 'YEAR') ,-9)
7 ELSE
8 ADD_MONTHS(TRUNC(SYSDATE, 'YEAR'), 3)
9 END FINANCIAL_YEAR
10 FROM dual;
FINANCIAL
---------
01-APR-15
For date between JAN and MAR of next year:
SQL> SELECT
2 CASE
3 WHEN
4 DATE '2016-02-01' < ADD_MONTHS(TRUNC(DATE '2016-02-01', 'YEAR'), 3)
5 THEN
6 ADD_MONTHS(TRUNC(DATE '2016-02-01', 'YEAR') ,-9)
7 ELSE
8 ADD_MONTHS(TRUNC(DATE '2016-02-01', 'YEAR'), 3)
9 END FINANCIAL_YEAR
10 FROM dual;
FINANCIAL
---------
01-APR-15
Following SQLreturns start and end date for Financial Year of current date.
SELECT
TO_DATE('01-04' || EXTRACT(YEAR FROM add_months(sysdate, -3)),'DD-MM-RRRR') from_dt ,
TO_DATE('31-03' || EXTRACT(YEAR FROM add_months(sysdate, 9)),'DD-MM-RRRR') to_dt from dual;
For any random date, you can use the following SQL: example for 01-04-2020
SELECT
TO_DATE('01-04' || EXTRACT(YEAR FROM add_months(to_date('01-04-2020','DD-MM-RRRR'), -3)),'DD-MM-RRRR') from_dt ,
TO_DATE('31-03' || EXTRACT(YEAR FROM add_months(to_date('01-04-2020','DD-MM-RRRR'), 9)),'DD-MM-RRRR') to_dt from dual;
