USER_INFO: DAYS_UNTIL_PASSWORD_EXPIRES

Read the fine print on DAYS_UNTIL_PASSWORD_EXPIRES on USER_INFO
<snip>
The number of days until the password will expire. Contains null if the
password will not expire within the number of days specified by the
password expiration warning (QPWDEXPWRN) system value.

Stick to something like
select
AUTHORIZATION_NAME,
DATE_PASSWORD_EXPIRES,
DAYS_UNTIL_PASSWORD_EXPIRES,
days(DATE_PASSWORD_EXPIRES) - days(current date) as
REAL_DAYS_UNTIL_PASSWORD_EXPIRES
from QSYS2.User_info
order by REAL_DAYS_UNTIL_PASSWORD_EXPIRES asc;

"real" will return a null if their password never expires
(DATE_PASSWORD_EXPIRES is null). At least in Run SQL Scripts. Perhaps
that nulls errors? If in doubt, wrap it in an ifnull.
