I have been working on a query that is making me go crazy because I couldn't seem to understand the error message: my query is:
SELECT MYTABLE." ID ",
NVL(max(TO_DATE(TO_CHAR(ADD_MONTHS(MYTABLE." XISSU_DT " ,MYTABLE." XTNR "), 'DD/MM/YYYY'),'DD/MM/YYYY')), TO_DATE(SYSDATE , 'DD/MM/YYYY') ) MAXLASTINSDATE,
TO_DATE(SYSDATE , 'DD/MM/YYYY'),
(TO_CHAR (TO_DATE(SYSDATE , 'DD/MM/YYYY')
- TO_DATE(NVL(max(TO_DATE(TO_CHAR(ADD_MONTHS(MYTABLE." XISSU_DT " ,MYTABLE." XTNR "), 'DD/MM/YYYY'),'DD/MM/YYYY')), TO_DATE(SYSDATE , 'DD/MM/YYYY') ) , 'DD/MM/YYYY')) * -1) MaturityPeriod
FROM MYTABLE
where
MYTABLE." STATUS " = 'A'
group by MYTABLE." ID "
the Error I have been getting is:
ora-01841 full year must be between 4713 and 9999 and not be 0
Your help is really appreciated!
TO_DATE(TO_CHAR(datevalue, 'DD/MM/YYYY'),'DD/MM/YYYY') is removing any time component which is effectively the same as: TRUNC( datevalue ).
Then TO_DATE(SYSDATE , 'DD/MM/YYYY') is probably where your error lies as TO_DATE( stringvalue, format_model ) takes a string as the first argument so you are effectively doing:
TO_DATE(
TO_CHAR(
SYSDATE,
( SELECT value FROM NLS_SESSION_PARAMETERS WHERE parameter = 'NLS_DATE_FORMAT' )
),
'DD/MM/YYYY'
)
It doesn't make sense as SYSDATE is already of the DATE data type so you don't need to use TO_DATE with it.
Finally, TO_CHAR(SYSDATE - datevalue)*-1 Why are you converting it to a string then multiplying it by a number when you can just do:
(SYSDATE - datevalue)*-1
But you don't even need the *-1 as you can just swap the terms around:
(datevalue - SYSDATE)
Tidying it all up you want something like:
SELECT MYTABLE." ID ",
NVL(
MAX( TRUNC( ADD_MONTHS(MYTABLE." XISSU_DT " ,MYTABLE." XTNR ") ) ),
SYSDATE
) MAXLASTINSDATE,
SYSDATE,
( NVL(
MAX( TRUNC( ADD_MONTHS(MYTABLE." XISSU_DT " ,MYTABLE." XTNR ") ) ),
SYSDATE
)
- SYSDATE
) AS MaturityPeriod
FROM MYTABLE
where MYTABLE." STATUS " = 'A'
group by MYTABLE." ID "

I am using the code below to generate random dates, which works fine.
Can this be modified to add a random time to the date between from 00:00:00 - 23:59:59
My attempt below failed and I'm unsure why. Any help would be greatly appreciated.
ALTER SESSION SET NLS_DATE_FORMAT = 'MMDDYYYY HH24:MI:SS';
SELECT TO_DATE(
TRUNC(
DBMS_RANDOM.VALUE(TO_CHAR(DATE '2021-01-01','J')
,TO_CHAR(DATE '2022-12-31','J')
)
),'J' +
NUMTODSINTERVAL(FLOOR(DBMS_RANDOM.VALUE(0,86399)), 'SECOND')
) FROM DUAL;
You have brackets in the wrong place:
SELECT TO_DATE(
TRUNC(
DBMS_RANDOM.VALUE(
TO_CHAR(DATE '2021-01-01','J'),
TO_CHAR(DATE '2022-12-31','J')
)
),
'J'
)
+ NUMTODSINTERVAL(
FLOOR(DBMS_RANDOM.VALUE(0,86399)),
'SECOND'
)
FROM DUAL;
Note: it helps if you format your code so that indentation matches the brackets and then you can more easily spot errors like this.
You can simplify the code to:
SELECT DATE '2021-01-01'
+ NUMTODSINTERVAL(
DBMS_RANDOM.VALUE(0, DATE '2022-12-31' - DATE '2021-01-01' + 1),
'DAY'
)
FROM DUAL;
Or, even simpler:
SELECT DATE '2021-01-01'
+ DBMS_RANDOM.VALUE(0, DATE '2022-12-31' - DATE '2021-01-01' + 1)
FROM DUAL;

So I have this working SQL script that take a date and returns the age from current time to the given date excluding dates defined in a table called exclude dates
SELECT
COUNT(*)
FROM
(
SELECT
ROWNUM rnum
FROM
all_objects
WHERE
ROWNUM <= CAST(current_timestamp AS DATE) - to_date('&2') + 1
)
WHERE
to_char(to_date('&2') + rnum - 1, 'DY') NOT IN ( 'SAT', 'SUN' )
AND NOT EXISTS (
SELECT
NULL
FROM
exclude_dates
WHERE
no_work = trunc(to_date('&2') + rnum - 1)
);
I have a table called
TICKETS
that contains columns named
ID, UPDATED_AT
I want to create a view that uses the above script to return
ID, AGE
where age is the output of the script above.
You code has a few weaknesses.
There is no need for CAST(current_timestamp AS DATE).
If you need the current DATE then simply use TRUNC(SYSDATE)
You don't need to select from all_objects. Better use hierarchical query
SELECT LEVEL as rnum FROM dual CONNECT BY LEVEL <= ...
Using to_date('&2') without a format is usually bad. Either your input value is a string, then you should include the format, e.g. to_date('&2', 'YYYY-MM-DD') or your input value is a DATE, then simply use &2 - never use TO_DATE() on a value which is already a DATE!
Final query could be this one - assuming input parameter is a DATE value:
WITH t AS (
SELECT LEVEL as d
FROM dual
CONNECT BY LEVEL <= TRUNC(SYSDATE) - the_day)
SELECT COUNT(*) AS buisiness_days
FROM t
WHERE TO_CHAR(the_day + d - 1, 'DY', 'NLS_DATE_LANGUAGE = american') NOT IN ('SAT', 'SUN')
AND NOT EXISTS (
SELECT 'x'
FROM exclude_dates
WHERE no_work = TRUNC(the_day + d - 1)
)
However, for me it is not clear how you want to provide this as a view! You would need to create a separate view for each input date, or at least create a new view every day.
I would suggest to create a function:
CREATE OR REPLACE FUNCTION buisiness_days(the_date IN DATE) RETURN INTEGER AS
ret INTEGER;
BEGIN
WITH t AS (
SELECT LEVEL as d
FROM dual
CONNECT BY LEVEL <= TRUNC(SYSDATE) - the_date)
SELECT COUNT(*) AS buisiness_days
INTO ret
FROM t
WHERE TO_CHAR(the_date + d - 1, 'DY', 'NLS_DATE_LANGUAGE = american') NOT IN ('SAT', 'SUN')
AND NOT EXISTS (
SELECT 'x'
FROM exclude_dates
WHERE no_work = TRUNC(the_date + d - 1)
);
RETURN ret;
END;
The function will return a list of dates between the date range you provide so the dates don't have to be stored in a table.
CREATE OR REPLACE TYPE nt_date IS TABLE OF DATE;
/
CREATE OR REPLACE FUNCTION generate_dates_pipelined(
p_from IN DATE,
p_to IN DATE
)
RETURN nt_date PIPELINED DETERMINISTIC
IS
v_start DATE := TRUNC(LEAST(p_from, p_to));
v_end DATE := TRUNC(GREATEST(p_from, p_to));
BEGIN
LOOP
PIPE ROW (v_start);
EXIT WHEN v_start >= v_end;
v_start := v_start + INTERVAL '1' DAY;
END LOOP;
RETURN;
END generate_dates_pipelined;

To exclude holidays you need to know what dates they fall on so there needs to be a holiday table.
create table holidays(
holiday_date DATE not null,
holiday_name VARCHAR2(20),
constraint holidays_pk primary key (holiday_date),
constraint is_midnight check ( holiday_date = trunc ( holiday_date ) )
);
INSERT into holidays (HOLIDAY_DATE,HOLIDAY_NAME)
WITH dts as (
select to_date('25-NOV-2021 00:00:00','DD-MON-YYYY HH24:MI:SS'), 'Thanksgiving 2021' from dual union all
select to_date('29-NOV-2021 00:00:00','DD-MON-YYYY HH24:MI:SS'), 'Hanukkah 2021' from dual
)
SELECT * from dts;
This query will provide the count of days between the range, number of working days and number of holidays in the range.
SELECT COUNT (*) AS total_days
, COUNT ( CASE
WHEN h.holiday_date IS NULL
AND d.column_value - TRUNC (d.column_value, 'IW') < 5
THEN 'Business Day'
END
) AS business_days
, COUNT (h.holiday_date) AS holidays
FROM generate_dates_pipelined (DATE '2021-11-01', DATE '2021-11-30') d
LEFT JOIN holidays h ON h.holiday_date = d.column_value;
This query will provide a list of dates excluding sat, sun and holidays that fall between the range.
SELECT
COLUMN_VALUE
FROM
TABLE(generate_dates_pipelined(DATE '2021-11-01',
DATE '2021-11-30')) c
where
to_char(COLUMN_VALUE, 'DY') NOT IN ('SAT', 'SUN')
AND NOT EXISTS (
SELECT 1
FROM holidays h
WHERE c.COLUMN_VALUE = h.holiday_date
);
You don't need a function or to use a row generator function and can calculate the number of business days:
CREATE VIEW business_day_ages (ID, AGE) AS
SELECT id,
( TRUNC( SYSDATE, 'IW' ) - TRUNC( updated_at, 'IW' ) ) * 5 / 7
-- Number of full weeks.
+ LEAST( SYSDATE - TRUNC( SYSDATE, 'IW' ), 5 )
-- Add part weeks at the end.
- LEAST( updated_at - TRUNC( updated_at, 'IW' ), 5 )
-- Subtract part weeks at the start.
- COALESCE(
( SELECT SUM(
LEAST(no_work + INTERVAL '1' DAY, SYSDATE)
- GREATEST(no_work, updated_at)
)
FROM exclude_dates
WHERE no_work BETWEEN TRUNC(updated_at) AND SYSDATE
),
0
)
-- Subtract the holiday days.
FROM tickets;
Or, if you are not calculating using part days then you can simplify it to:
CREATE OR REPLACE VIEW business_day_ages (ID, AGE) AS
SELECT id,
( TRUNC( SYSDATE, 'IW' ) - TRUNC( updated_at, 'IW' ) ) * 5 / 7
-- Number of full weeks.
+ LEAST( TRUNC(SYSDATE) - TRUNC( SYSDATE, 'IW' ), 5 )
-- Add part weeks at the end.
- LEAST( updated_at - TRUNC( updated_at, 'IW' ), 5 )
-- Subtract part weeks at the start.
- COALESCE(
( SELECT 1
FROM exclude_dates
WHERE no_work BETWEEN TRUNC(updated_at) AND TRUNC(SYSDATE)
),
0
)
-- Subtract the holiday days.
FROM tickets;

Table t_customer_statistics
trx_date - transaction date
cuid - id person(divide prospect and client)
lifecycle_status - this column must be filled
I need to give status to a client based on his condition
acquired - this month was the very first transaction
existing - there was a transaction last month
reactivated - there was no transaction last month
sleeping - there has been no transaction for the last 90 days (there have been no subsequent ones since the last transaction, more than 90 days)
I roughly made a code like this
UPDATE t_customer_statistics
SET Lifecycle_status =
case
when to_char (trunc (trx_date, 'mm'), 'mm.yyyy') = to_char (trunc (sysdate, 'mm'), 'mm.yyyy') then 'acquired'
when to_char (trunc (trx_date, 'mm'), 'mm.yyyy') = to_char (trunc (sysdate, 'mm') - 1, 'mm.yyyy') then 'existing'
when to_char (trunc (trx_date, 'mm'), 'mm.yyyy') = to_char (trunc (sysdate, 'mm') - 40, 'mm.yyyy') then 'reactivated'
when to_char (trunc (trx_date, 'mm'), 'mm.yyyy') <to_char (trunc (sysdate, 'mm') - 90, 'mm.yyyy') then 'sleeping'
end
but when they gave me an example, if the client made the first transaction and then fell asleep, then he has two states in the end, and sleeping must be separated so that there is a separate
PS. must be considered by transaction from the first and last
You could use a MERGE statement like this:
MERGE INTO clients dst
USING (
SELECT rowid rid,
LEAD(dt, 1) OVER (PARTITION BY id ORDER BY dt DESC) AS prev_dt,
LAG(dt, 1) OVER (PARTITION BY id ORDER BY dt DESC) AS next_dt
FROM clients
) src
ON ( dst.ROWID = src.rid )
WHEN MATCHED THEN
UPDATE
SET status = CASE
WHEN prev_dt IS NULL
THEN 'acquired'
WHEN MONTHS_BETWEEN(TRUNC(dst.dt, 'MM'), TRUNC(src.prev_dt)) <= 1
THEN 'existing'
ELSE 'reactivated'
END
||
CASE
WHEN COALESCE(src.next_dt, SYSDATE) >= dst.dt + INTERVAL '90' DAY
THEN ', sleeping'
END;
Which, for the sample data:
CREATE TABLE clients (id, dt, status ) AS
SELECT 1, DATE '2020-01-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-02-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-03-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-05-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-09-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-10-01', CAST( NULL AS VARCHAR2(20) ) FROM DUAL UNION ALL
SELECT 1, DATE '2020-10-01' + INTERVAL '91' DAY, CAST( NULL AS VARCHAR2(20) ) FROM DUAL;
Then the result of the MERGE is:
ID
DT
STATUS
1
01-JAN-20
acquired
1
01-FEB-20
existing
1
01-MAR-20
existing

01-MAY-20
reactivated, sleeping
1
01-SEP-20
reactivated
1
01-OCT-20
existing, sleeping
1
31-DEC-20
reactivated, sleeping

I am trying to figure out how to create an SQL query that will check for (:FROM_DATE) and (:TO_DATE) parameters and if NULL to put the past month dates in for the two values, and if not NULL to accept whatever values are entered in the parameters.
For example:
if the user enters (01-JAN-17) as FROM_DATE, and (31-JAN-17) as TO_DATE, I want the query to not automatically pass any values for the TO_DATE and FROM_DATE.
if the user does not enter any values for TO_DATE and FROM_DATE or there are NULL values passed in, I want the query to automatically enter the the past months values (i.e., if query is run July 1st 2017, the FROM_DATE would be 01-JUN-17 and the TO_DATE would be 30-JUN-17).
I was hinted to use a coalesce statement to handle multiple values and NULLS (i.e., AND ( (coalesce(null, :P_ORG) is null) or (ORG.ORGANIZATION_ID in :P_ORG)))???
Any help would be greatly appreciated.
Something like:
SELECT *
FROM your_table
WHERE your_date_column BETWEEN TO_DATE( :from_date, 'DD-MON-YYYY' )
AND TO_DATE( :to_date, 'DD-MON-YYYY' )
OR ( ( :from_date IS NULL OR :to_date IS NULL )
AND your_date_column BETWEEN ADD_MONTHS( TRUNC( SYSDATE, 'MM' ), -1 )
AND TRUNC( SYSDATE, 'MM' ) - 1
);
If either (or both) :from_date or :to_date is NULL then the dates will be compared to the previous month.
If your table has dates where the time component is not always set to midnight then you will need to use:
SELECT *
FROM your_table
WHERE your_date_column BETWEEN TO_DATE( :from_date, 'DD-MON-YYYY' )
AND TO_DATE( :to_date, 'DD-MON-YYYY' )
OR ( ( :from_date IS NULL OR :to_date IS NULL )
AND your_date_column >= ADD_MONTHS( TRUNC( SYSDATE, 'MM' ), -1 )
AND your_date_column < TRUNC( SYSDATE, 'MM' )
);
Proof of concept: consider the following query, where we have dates and values, and we want to sum the values for the dates that fall between :from_date and :to_date. If either of them is null, the query will use the first day of the prior month for from_date and the last day of the prior month for to_date. Note that this will cause problems if one date is given an actual value and the other is left null - you didn't explain how you would want that handled. But that's a different issue.
I use SQL developer, and in it I don't know how to pass in dates; I show passing in strings, and converting them to dates.
with
test_data ( dt, val ) as (
select date '2017-05-29', 200 from dual union all
select date '2017-06-13', 150 from dual union all
select date '2017-06-18', 500 from dual
)
select sum(val) as sum_val
from test_data
where dt between coalesce(to_date(:from_date, 'yyyy-mm-dd'),
add_months(trunc(sysdate, 'mm'), -1))
and coalesce(to_date(:to_date , 'yyyy-mm-dd'), trunc(sysdate, 'mm') - 1)
;
Yes, you can use COALESCE (or Oracle's NVL). When a parameter is null, replace it with the default date.
select *
from mytable
where mydate >= coalesce(:from_date, trunc(sysdate - interval '1' month), 'month')
and mydate <= coalesce(:to_date, last_day(sysdate - interval '1' month));

Adapted from my answer here:
Get the number of days between the Mondays of both weeks (using TRUNC( datevalue, 'IW' ) as an NLS_LANGUAGE independent method of finding the Monday of the week) then add the day of the week (Monday = 1, Tuesday = 2, etc., to a maximum of 5 to ignore weekends) for the end date and subtract the day of the week for the start date. Like this:
SELECT ( TRUNC( end_date, 'IW' ) - TRUNC( start_date, 'IW' ) ) * 5 / 7
+ LEAST( end_date - TRUNC( end_date, 'IW' ) + 1, 5 )
- LEAST( start_date - TRUNC( start_date, 'IW' ) + 1, 5 )
