Extracting words from a sentence in oracle - oracle

I have table and the table 'test' and it has column filename whilch contains differnt format of sentences.
filename
LA West Employer us Rort October 2015.txt201510
LA loyer sus Rrt April 2017
LA oyer sus Rept April 2018.txt201712
LA oyer sus Ret April 2019.txt201712
LA Eoyer sus Ret Aug 2019.txt201712
LA oyer sus Rort August 2017(2).txt201708
LA Eyer sus Rort August 2018 (1).txt201712
LA Eyer sus Reort Dec 2017.txt201711
LA Emyer sus Report Dec 2018 (1).txt201712
LA Emyer sus Report October- 2018 (1).txt201712
My expected output is:
October 2015
April 2017
Aug 2019
Dec 2017
Each row is containing Month year, I want to extract that part from it.
I tried as below:
SELECT
SubStr(filename,INSTR(filename,'Report')+7,(INSTR(filename,'(')-1)-(INSTR(filename,'Report')+7))res
FROM test ;
select regexp_substr(filename, '[^[:space:]]+[[:space:]][^[:space:]]+$') from table;
It didnot worked.How I can achieve this result?

A possible solution is:
select replace(regexp_substr('LLC Emyer sus Report October- 2018 (1).txt201712', '[[:alpha:]-]+[[:space:]][[:digit:]]{4}'), '-', '')
from dual;

This pattern also works fine
select FILENAME, regexp_substr(FILENAME, '([[:alpha:]]+\s+[[:digit:]]+)\s*(\([[:digit:]]+\))?\.txt.+?$', 1, 1, 'i', 1) expected_output
from your_table

Using a 0 rather than skipping the group entirely if nothing is found

How can I use a 0 as a "placeholder" here?
=QUERY(Data!A1:G578, "select G, sum(C) where D='Income' group by G label sum(C) 'Total Income'")
So that
Month
Total Income
August 2021
$784.59
October 2021
$200.00
November 2021
$312.74
becomes
Month
Total Income
August 2021
$784.59
September 2021
$0.00
October 2021
$200.00
November 2021
$312.74
The quickest hacky fix would be just to have an entry of 0$ for September in the data somewhere, but I am wondering if there is a more ""professional"" way to do it

Storing a date as a variable and using it in code (Oracle)

Oracle Version: 19.2.1.247
Good morning,
I am trying to get the most recent Friday and then store that date to use as a variable. I need to only bring forward those people who have a start date of 28 days or earlier from "my_date". Anyone over 28 days should be excluded.
here is what I have so far:
variable my_date varchar2(30)
exec :my_date := sysdate;
SELECT Distinct * from tbl1.people
where startdt < to_date(:my_date,(select next_day(trunc(sysdate-1), 'FRIDAY'-7 from dual))-35;
I am getting the following error message and I am not sure how to handle it:
ORA-00932: inconsistent datatypes: expected date got date
Here is an example of what I am trying to do:
Last Friday (Oct 23, 2020) is "my_date", so I need to go backwards for 28 days to Sept 25, 2020 and use that as the cutoff date. I do not want to see anyone with Sept 24,2020 or earlier.
The result set should be from Sept 25, 2020 to Oct 23, 2020 only.
Thank you for any help you can give!
To me, it looks as simple as
select *
from your_table
where startdt < next_day(sysdate - 7, 'FRIDAY') - 28;
because
SQL> select next_day(sysdate - 7, 'FRIDAY') - 28 from dual;
NEXT_DAY(S
----------
25.09.2020

How to get only the date in MVC

In MVC, right now in my view data format is: 25/06/1992 12:00:00 AM But i want only date: 25 jun 1992 in this format
string bdate = WMU.DOB.ToShortDateString();
string entrydate = WMU.EntryDate.ToShortDateString();
You can use dateTime.ToString("dd MMM yyyy"); for 25 Jun 1992

And then I tried to make a Trigger for updating instead of insert to the table when duplicate a primary key. The primary key is the first coloumn 'KD_CONTRACT'.
CREATE OR REPLACE TRIGGER INSERT_TABEL_CONTRACT
BEFORE INSERT ON CONTRACT
FOR EACH ROW
DECLARE
KODE VARCHAR2(20);
TEMPCARIKODE NUMBER;
BEGIN
SELECT LPAD(TO_NUMBER(NVL(SUBSTR(MAX(KD_CONTRACT),2),0))+1,3,'0') INTO KODE
FROM CONTRACT;
SELECT COUNT(KD_CONTRACT) INTO TEMPCARIKODE
FROM CONTRACT
WHERE KD_CONTRACT = :NEW.KD_CONTRACT;
IF(TEMPCARIKODE = 0) THEN
:NEW.KD_CONTRACT := 'C'||KODE;
:NEW.GABUNG := TO_NUMBER(TO_CHAR(SYSDATE,'YYYY'));
:NEW.BERAKHIR := :NEW.GABUNG + :NEW.BERAKHIR;
:NEW.BUYOUT := (:NEW.GAJI_PL * 52) * (:NEW.Berakhir-:NEW.Gabung) * 2;
END IF;
EXCEPTION
WHEN DUP_VAL_ON_INDEX THEN
DBMS_OUTPUT.PUT_LINE('');
DBMS_OUTPUT.PUT_LINE('');
DBMS_OUTPUT.PUT_LINE('ERROR at Line 1:');
DBMS_OUTPUT.PUT_LINE('ORA-20003: Data sudah ada, data akan diupdate!');
END;
/
show err;
anyway maybe the code show that I tried not to update when the primary key is duplicated. But please the until end first.
it show no error... So the trigger successfully created.
then I tried to insert a duplicated primary key.
INSERT INTO CONTRACT VALUES('C001','MA001','T001',2013,2,15000,2500000);
the result
INSERT INTO CONTRACT VALUES('C001','MA001','T001',2013,2,15000,2500000)
*
ERROR at line 1:
ORA-00001: unique constraint (TUGAS.PK_CONTRACT) violated
It did raise ORA-00001 but it never touched the DUP_VAL_ON_INDEX and showed nothing or the custom message.
Anyone have Idea? When it never even touch DUP_VAL_ON_INDEX then how could I event paste an update query at the when case...
Thanks...
* anyway my oracle is XE or express edition.
The EXCEPTION block from your trigger will never be executed since your trigger doesn't contain any INSERT or UPDATE statements.
You have to consider INSTEAD OF Trigger instead.

oracle query to convert number format to date format or vice versa

In DB, date is stored in number format (Mon Jul 07 14:41:40 IST 2014
is stored as 1404724300383), I need a query to convert number to date to compare with the sysdate, or from sysdate to number format. How can we convert the date to number or vice versa?
Assume the number is a sequencial one based on specific rule. You need to know the rule first.
Get the rule
a) 07 July 2014 = 1404724300383; 07 July 2013 = ? (assume 1404700000000)
b) Assume value 0 mapping to one day, Day1
c) two formulas 1404724300383 = (07 July 2014 - Day1) * RULE; 1404700000000 = (07 July 2013 - Day1)*Rule;
Then, Rule = 24300383/365 and Day 1 = 1 Jan 1900 + 41285/(1404724300383/1404700000000*41460/((1404724300383/1404700000000)-1))
where 41825 is the days between 07 July 2014 and 1 Jan 1900)
41460 is the days between 07 July 2013 and 1 Jan 1900)
Use the Rule and Day1 to get what you need
select Day1 + [query column]/Rule from Your_Table;
