Re: Identity value of 0

[Paul Bailey <PabloMotte+Midrange@xxxxxxxxx>]

I didn't think that was possible either. A pair of ideas:
- Was the file restored recently? There has been discussion recently on
this list about unexpected value in an ID column, but I didn't see mention
of a zero value in the ID column.
- If you have a journal attached, can you see the job/program that created
the rows? My thought would be that someone inserted a row specifying zero
as the ID column, but I thought that was impossible too. If it was possible
then an insert with a subselect, or a plain insert, might do it if you
don't specify "default" as the column value (or leave it out of the insert
column list).

HTH
Paul.
