Yeah, I realized this after I responded to you. My only thinking on this
is that the 'generate' option somehow forces you to model your database
field after the attributes of the special register.

What if you changed the change_user field to not be a generate-always field,
and allowed it to default like the create_user field?
There would be a chance that someone could overwrite the change_user field
on an insert, but is this something you can live with?

Hi Paul,

My question is really asking why the first column is okay using CHAR and the
second column not, when both are using the same special register.

The USER special register is defined as Varchar(18) so I would guess
anything that uses the User would also need to be varchar(18).

From SQL Reference...
USER
The USER special register specifies the run-time authorization ID at
the current server. The data type of the special register is
VARCHAR(18).

Subject: Why does USER require VARCHAR and not work with CHAR?

Hi there,

IBM i 7.3, TR 2, cum level 17061, DB2 PTF group level 6

I have a CREATE TABLE statement where the create user column is using
CHAR(18) and the change user column won't allow CHAR(18) but works if
VARCHAR(18).
Why can't they both be CHAR(18)?

This won't work:

CREATE OR REPLACE TABLE glenn_test_table FOR SYSTEM NAME test_table (
create_user FOR COLUMN recrtuser CHAR(18) CCSID 37 NOT NULL DEFAULT
USER ,
change_user FOR COLUMN rechguser CHAR(18) CCSID 37 NOT NULL
GENERATED ALWAYS AS (USER) )
RCDFMT RPCMMNT

SQL0574 Column, sequence, or variable attribute is not valid.

This does work:

CREATE OR REPLACE TABLE glenn_test_table FOR SYSTEM NAME test_table (
create_user FOR COLUMN recrtuser CHAR(18) CCSID 37 NOT NULL DEFAULT
USER ,
change_user FOR COLUMN rechguser VARCHAR(18) CCSID 37 NOT NULL
GENERATED ALWAYS AS (USER) )
RCDFMT RPCMMNT

My question, why?


Yours truly,
