Allow shorter audit value columns

The audit columns defined as GENERATED ALWAYS AS USER, SESSION_USER or CURRENT CLIENT_USERID require the column to be either 18, 128 or 255 bytes.

While this is maybe a theoretical limit it makes no sense in 99.999% of the cases as usernames on IBM i can only be 10 characters and on other platforms no-one is using such long user names (maybe 20 characters max).

Using ALLOCATE limits the overhead on the table, but not on journals.


Use Case:

It would therefore be logical that the length of those fields is not enforced but that I can choose myself which length it should be (and DB2 for i should just truncate - with no error - the value if it is ever longer)

    IBM does not intend to provide a solution to this request at this time, so it is being closed.

    While we agree that this is a valid request, we do not currently plan to implement it because there is a long list of higher priority requirements.

    The SESSION_USER and USER special registers are always the same value, so consider using USER. CURRENT CLIENT_USERID is one of the special registers that can be modified by an application to contain any application-provided value. Allowing a shorter column length for this auditing value could be expected to lose meaningful data.
