Enhance VARCHAR format option for EUR,JIS,ISO,USA but for LOCAL option

Today, VARCHAR supports a 2nd parameter when the first parameter is a date/time value. That 2nd parameter returns the resulting date value in the designated format.

The LOCAL option returns the value in the Job's format. I would like this enhanced to return the value in the Job's format but with a 4-digit year component. 

That is if in the LOCAL format is MDY, then the returned value would be MM/DD/YYYY, and if LOCAL is DMY then it would return DD/MM/YYYY

Perhasp LOCALEX or LOCAL4 or similar could be used. 

The benefit is that we're trying to avoid End-Users being confused by 3-two-digit components and not really trusting which one is which. So we're trying to avoid the 2-digit year presentation in 100% of the interfaces we are providing.

    IBM does not intend to provide a solution to this Idea at this time, so it is being closed. Adding new date formats is not a trivial change. The database team has many other higher priority enhancement requests, so this Idea would be unlikely to be implemented any time soon.

    We also want to point out that adding a 4-digit year version of our proprietary date formats does not remove the ambiguity. The month and day can still appear in different orders for MM/DD/YYYY and DD/MM/YYYY. Returning the date using one of the industry standard formats (*ISO, *EUR, *USA, *JIS) is recommended.

    You could build your own function to generate a 4-digit year format. The following partial example demonstrates one way to do this. It uses the knowledge that 99 can only be a year and that 30 cannot be a month to determine what date format is used by the job.

    values case when try_cast('01/30/99' as date) is not null then varchar_format (current date, 'MM/DD/YYYY')
    when try_cast('30/01/99' as date) is not null then varchar_format (current date, 'DD/MM/YYYY')
    when try_cast('99/01/30' as date) is not null then varchar_format (current date, 'YYYY/MM/DD')
    else char(current date) end;

    The CAAC has reviewed this IBM Idea and recommends that IBM view this as a “nice to have” low priority feature.

    There is value in the community seams to be low.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual IBM Ideas on the broader IBM i community and has therefore reviewed your Idea.
