I have a column with dates formatted as decimals, for example: 20,210,830.
I want to convert this number to date format as 08/30/2021
I have tried to use convert and the database shoots me an error that convert is not a valid function. Cast seems to work but, only returns a null value every time.
This statement will validate:
SELECT CAST(CAST(CONTCLMPDTE AS VARCHAR(8)) AS DATE)
FROM CMSFIL.JCTDSC AS COMPLDATE
This statement works but, just outputs null. For background I am querying from a Db2 database.
My ultimate goal is to use this converted date to grab the difference from the current day.
Such as
DAY(CURRENT_DATE) - DAY(COMPLDATE)
Converting it to a date, you cqan do it like this
CREATE TABLE JCTDSC (
CONTCLMPDTE varchar(10)
);
INSERT INTO JCTDSC VALUES ('20,220,830')
SELECT date(to_date(REPLACE(CONTCLMPDTE,',',''),'YYYYMMDD')) FROM JCTDSC AS COMPLDATE
1 |
---|
2022-08-30 |
DATE (TO_DATE (CAST (20220830 AS CHAR (8)), 'YYYYMMDD'))
So after a long couple days and almost pulling my hair out, here is what worked for me.
SELECT date(substr(CONTCLMPDTE,1,4)||'-'||substr(CONTCLMPDTE,5,2)||'-'||substr(CONTCLMPDTE,7,2)) FROM JCTDSC WHERE COMPANYNUMBER={Company Number} AND JOBNUMBER={Job Number} LIMIT 1
This formatted from yyyymmdd to mm/dd/yyyy. It also worked for finding the days between current_date and CONTCLMPDTE using this code.
DAYS(CURRENT_DATE) - DAYS({COntract Compl Date Formatted})
Thank you all for your help!
The value just need to be converted into a string with a date format. Then you can use the date() function to convert to date.
create table qtemp/dec_vals (
col1 decimal(8,0) );
insert into qtemp/dec_vals
values (20200830), (20200831), (20200901), (20200902), (20200903), (20200904), (20200905), (20200906);
select date(substr(char(col1), 5, 2) || '/' || substr(char(col1), 7, 2) || '/' || substr(char(col1), 1, 4)) from qtemp/dec_vals;
