Re: auto generated ID as primary key

IDK where you get the idea that it's bad practice to have keys defined in
tables like that. Perhaps that was true back on the S/3 but it hasn't
been true for a long time now.

What is your definition of rehome? Save/restore to a different library,
system, ?

Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxx>



though i know this is bad practice (to have keys defined in tables), my
current employer currently has tables with...

L_ID for column ID
BIGINT not null generated always as
identity (start with 1 increment by 1),

Now when this file is "re-homed" it knocks the auto generate row id out of
whack and creates a duplicate record error when a pgm tries to write to
it. And of course we have to manually reset the row id.

My guess is because of the (start with 1 increment by 1) - meaning, once
it
is re-homed it somehow thinks it needs to start at 1 again.

Is that true? Ideally i'd like to remove the ID from being a primary key
on the table, but would at least removing (start with 1 increment by 1)
resolve the re-homing and duplicate record issue, or no? How exactly does
this work?
