I am trying to write a query that will return the last friday of the previous month This is what I have so far.
SELECT sysdate
FROM DUAL
where (LAST_DAY( SYSDATE ) - INTERVAL '7' DAY,
'Friday' );
Consider:
select next_day(trunc(sysdate, 'month') - interval '8' day, 'Friday') from dual
Rationale:
trunc(sysdate, 'month') gives you the first day of the current month
we offset that value by 8 days so we can the the date 7 days before the end of the previous month
then, next_day() returns the next Friday after this date, that is the last Friday of the month
Try this:
SELECT NEXT_DAY( LAST_DAY( TO_DATE('01-' || TO_CHAR(SYSDATE, 'MON-YYYY')) - 1 ) - INTERVAL '7' DAY, 'FRIDAY' ) FROM DUAL;

So I've been trying to fetch some daily data with SYSDATE on a date type YYYYMMDD as following:
SELECT dates, trunc(calendar_date, 'DD') calendar_dates, weekday_nbr
FROM db.date
WHERE dates BETWEEN to_char(TRUNC(SYSDATE)-2, 'YYYYMMDD') AND to_char(TRUNC(SYSDATE)-1, 'YYYYMMDD')
But now I'm trying to use the same but on a YYYY+MM+Week date type with not much success
I tried using:
SELECT T time, period, fiscal_week
FROM db.time
WHERE time BETWEEN to_char(TRUNC(SYSDATE)-2, 'W') AND to_char(TRUNC(SYSDATE)-1,'W')
With time as a 7 digit number, and period and fiscal week as a 2 digit number
Knowing that there's no way I can truncate such date type, how can TRUNC SYSDATE YYYY+MM+Week to get the data on the last 2 weeks?
Also I was thinking about maybe getting the totals from a set day and then dropping all but the last 2 weeks, but on the long run maybe that would be time consuming.
Knowing that there's no way I can truncate such date type, how can TRUNC SYSDATE YYYY+MM+Week to get the data on the last 2 weeks?
Assuming that your fiscal weeks are from Monday-Sunday then you can truncate to the start of the ISO week (which is always Midnight on Monday) and use that for the basis of the comparison:
SELECT *
FROM db.time
WHERE dates >= TRUNC(SYSDATE, 'IW') - INTERVAL '14' DAY
AND dates < TRUNC(SYSDATE, 'IW')
If you have a column that is for weeks then you should still use a DATE data type and add a CHECK constraint (and can use virtual columns to generate the week and the year):
CREATE TABLE time (
dt DATE
CHECK (dt = TRUNC(dt, 'IW')),
year NUMBER(4,0)
GENERATED ALWAYS AS (EXTRACT(YEAR FROM dt)),
month NUMBER(2,0)
GENERATED ALWAYS AS (EXTRACT(MONTH FROM dt)),
week NUMBER(1,0)
GENERATED ALWAYS AS (FLOOR((dt - TRUNC(dt, 'MM'))/7) + 1),
time VARCHAR2(7)
GENERATED ALWAYS AS (
CAST(
TO_CHAR(dt, 'YYYYMM')
|| (FLOOR((dt - TRUNC(dt, 'MM'))/7) + 1)
AS VARCHAR2(7)
)
)
-- ...
);
fiddle
Then you can use the logic above on the date column.
If you do not have a DATE column then you will need to convert your YYYYMMW number into a DATE and then use the logic above.
For example, if the logic for your fiscal weeks (which you have not described) is that the first week of each month starts on the first Monday of the month then you can convert the YYYYMMW number to a DATE using:
SELECT NEXT_DAY(
TO_DATE(SUBSTR(time, 1, 6), 'YYYYMM') - INTERVAL '1' DAY,
'MONDAY'
) + INTERVAL '7' DAY * (SUBSTR(time, 7, 1) - 1) AS week_start
FROM db.time
and then could use it to filter the table using:
SELECT *
FROM (
SELECT t.*,
NEXT_DAY(
TO_DATE(SUBSTR(time, 1, 6), 'YYYYMM') - INTERVAL '1' DAY,
'MONDAY'
) + INTERVAL '7' DAY * (SUBSTR(time, 7, 1) - 1) AS week_start
FROM db.time t
)
WHERE week_start >= TRUNC(SYSDATE, 'IW') - INTERVAL '14' DAY
AND week_start < TRUNC(SYSDATE, 'IW')
If you have different logic for calculating when fiscal weeks start then you will need to apply that logic to the conversion.
I have a where clause with a date field, I want it to find the latest Friday when this auto runs every Monday or Tuesday of the following week.
Currently:
WHERE b.CALENDAR_DATE = To_Date('2020-08-30', 'YYYY-MM-DD')
I want to find the latest Friday
You can use TRUNC( date_value, 'IW' ) (which is language independent) to truncate to the start of the ISO week, which is always a Monday, and then subtract 3 days. You will also want to add 2 days before truncating so that the filter is correct if SYSDATE is a Saturday or Sunday.
WHERE b.CALENDAR_DATE >= TRUNC( SYSDATE + INTERVAL '2' DAY, 'IW' ) - INTERVAL '3' DAY
AND b.CALENDAR_DATE < TRUNC( SYSDATE + INTERVAL '2' DAY, 'IW' ) - INTERVAL '2' DAY
(Note: dates can have a non-zero time component so if you want all dates on the last Friday then you will need a range of values rather than just comparing to last Friday at midnight.)
Or you can use NEXT_DAY( date_value - INTERVAL '8' DAY, 'FRIDAY' ) (which is language dependent):
WHERE b.CALENDAR_DATE >= NEXT_DAY( TRUNC( SYSDATE ) - INTERVAL '8' DAY, 'FRIDAY' )
AND b.CALENDAR_DATE < NEXT_DAY( TRUNC( SYSDATE ) - INTERVAL '8' DAY, 'FRIDAY' ) + INTERVAL '1' DAY

How do I get the last day of the month to be 11:59:59 pm? Right now it is showing 05/31/2019 12:00 AM. If I just do sysdate it just shows the time I ran it. Thanks.
LAST_DAY(TRUNC(SYSDATE,'MM'))
Try adding one day to the last day of the current month, then subtracting one minute:
SELECT
LAST_DAY(TRUNC(SYSDATE,'MM')) + INTERVAL '1' DAY - INTERVAL '1' SECOND
FROM dual;
Or, if you want to also see the time component, use CURRENT_TIMESTAMP in place of SYSDATE:
SELECT
LAST_DAY(TRUNC(CURRENT_TIMESTAMP,'MM')) + INTERVAL '1' DAY - INTERVAL '1' SECOND
FROM dual;
This outputted:
30.06.2019 23:59:59
The oldfashioned way would be to subtract a second (that's what 1 / (24*60*60) represents as there are 24 hours in a day, 60 minutes in an hour and 60 seconds in a minute) from the first day of the next month (and that's what trunc(add_months(sysdate, 1)) does):
SQL> select sysdate today,
2 trunc(add_months(sysdate, 1)) - 1/(24*60*60) result
3 from dual;
TODAY RESULT
---------------------- ----------------------
06/01/2019 07:52:40 AM 06/30/2019 11:59:59 PM
SQL>
I would use:
SELECT TRUNC(SYSDATE, 'MM') + INTERVAL '1' MONTH - INTERVAL '1' SECOND
FROM dual;
(This has one less step than Tim's solution.)
Or in the older-fashioned method:
SELECT ADD_MONTHS(TRUNC(SYSDATE, 'MM'), 1) - 1/(24*60*60)
If you convert this to a timestamp, you will see the time value:
SELECT CAST(TRUNC(sysdate, 'MM') + INTERVAL '1' MONTH - INTERVAL '1' SECOND as TIMESTAMP)
FROM dual;
I want to fetch data of last 4 quarter including current quarter.
Suppose if I run the query on 30-MAR-2019 then I want data from 01-APR-2018 to 31-MAR-2019
and if I run the query on 01-apr-2019 then I want data between 01-JUL-2018 and 30-JUN-2019
Could you please help me on the same
The tricky part is getting the last day of the quarter.
This solution calculates the starting day of the range by subtracting 9 months from the target date and then truncating with the 'Q' mask which gives us the first day of the quarter. We then calculate that date again, subtract one day then add twelve months and that gives the last day of the current quarter:
with tgt as ( select date '2019-03-30' as dt from dual
union all select date '2019-02-28' as dt from dual
union all select date '2019-04-01' as dt from dual
)
select trunc(tgt.dt - interval '9' month, 'Q') as range_st,
(trunc(tgt.dt - interval '9' month, 'Q') - 1) + interval '12' month as range_end
from tgt
/
There may be a slicker solution out there, but this is the end of my coffee break :)
this will work:
select TRUNC(sysdate+1, 'Q') - interval '9' month,TRUNC(sysdate+1, 'Q') +
interval '3' month -1
from dual ;
01-JUL-2018 30-JUN-2019
select TRUNC(to_date('30-MAR-2019')+1, 'Q') - interval '9'
month,TRUNC(to_date('30-MAR-2019')+1, 'Q') + interval '3' month -1
from dual ;
01-APR-2018 31-MAR-2019
This is dynamically:
With param as (
Select
to_date(extract(year from add_months(sysdate,-12)) ||
lpad((floor(extract(month from add_months(sysdate,-12))/3)*3)+1,2, '0') || '01',
'yyyymmdd') first_date
from dual
)
Select
level quartal,
Add_months(first_date, ((level-1)*3)) from_dat,
Last_day(add_months(first_date, ((level-1)*3)+3)-1) to_dat
From param
connect by level <= 4;
You can do:
select (trunc(sysdate, 'Q') + interval '3' month) as next_quarter_start,
(trunc(sysdate, 'Q') + interval '15' month) - interval '1' day as next_quarter_end
from dual;
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."
FROM

AND ( REPAIR_CURRENT.REP_SRQ_NO=SERVICE_REQUEST.SRQ_NO )
AND

--AND
REPAIR_CURRENT.REP_RAISED_DATE BETWEEN '01-APR-2015' AND sysdate
AND
REPAIR_CURRENT.REP_STATUS <> 'CAN'
)
GROUP BY

PROPERTY.PRO_SCHEME,
to_char(REPAIR_CURRENT.REP_RAISED_DATE,'Mon'),
to_number(to_char(to_date(REPAIR_CURRENT.REP_RAISED_DATE,'dd-mon-yy'),'mm'))
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;
