I just want to format current date into yyyymmdd in DB2.
I see the date formats available, but how can I use them?
SELECT CURDATE() FROM SYSIBM.SYSDUMMY1;
I dont see any straightforward way to use the above listed formats.
Any suggestion?

SELECT VARCHAR_FORMAT(CURRENT TIMESTAMP, 'YYYYMMDD')
FROM SYSIBM.SYSDUMMY1
Should work on both Mainframe and Linux/Unix/Windows DB2. Info Center entry for VARCHAR_FORMAT().
One more solution REPLACE (CHAR(current date, ISO),'-','')
select to_char(current date, 'yyyymmdd') from sysibm.sysdummy1
result: 20160510
This isn't straightforward, but
SELECT CHAR(CURRENT DATE, ISO) FROM SYSIBM.SYSDUMMY1
returns the current date in yyyy-mm-dd format. You would have to substring and concatenate the result to get yyyymmdd.
SELECT SUBSTR(CHAR(CURRENT DATE, ISO), 1, 4) ||
SUBSTR(CHAR(CURRENT DATE, ISO), 6, 2) ||
SUBSTR(CHAR(CURRENT DATE, ISO), 9, 2)
FROM SYSIBM.SYSDUMMY1
Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:
select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)
