The forum has been slow so I figured I post something.
Just came across this function:
Code:
 VARCHAR_FORMAT

Read up on it, it's powerful. Many more formats available.

I use to do this:
Code:

                            SUBSTR(CHAR(BIRTH_DATE),1,4)
                        ||  SUBSTR(CHAR(BIRTH_DATE),6,2)
                        ||  SUBSTR(CHAR(BIRTH_DATE),9,2)

 


Now I do this:
Code:
VARCHAR_FORMAT(BIRTH_DATE,'YYYYMMDD')

NASCAR9,


Thanks for sharing. I would prefer using TO_CHAR instead of Varchar format as it would give you extra 2 bytes for length.

Code:

SELECT TO_CHAR(CURRENT DATE,'YYYYMMDD')     
  FROM SYSIBM.SYSDUMMY1                     
  ;                                         
or
SELECT TO_CHAR(CURRENT DATE,'MMDDYYYY')     
  FROM SYSIBM.SYSDUMMY1                     
  ;                                         
or
SELECT TO_CHAR(CURRENT DATE,'DD-MON-YYYY') 
  FROM SYSIBM.SYSDUMMY1                     
  ;                                         

You can also format the numbers with comma's as shown in this topic
