Обсуждение: Unknown values in int8 fields?
Hi Chris,
When I load records with copy <table> from ... And one of the fields (last
one) is left empty, I want the default of nextval('sequence_table') to kick
in - but it doesn't.
Now, the field with a unique index on it stays blank. No big deal if I could
go and say 'update rate set recno = nextval('sequence_rate') where recno = 0
- but it's not that easy as the recno is not 0 but - hmm what? What can I
check for? I tried '?' and ? And 0 and ... And ... And ... But nothing works
... Now what?
Best regards
Chris

I've not been following this too closely but it sounds like you are
trying to COPY records from table A to table B, where the table B
also includes a serial value.
Here's an easy trick which I'm pretty sure will work: instead of
using COPY use SELECT INTO. It's much slower but I think it will
do the trick.
Good luck! HTH.

TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to
majordomo@postgresql.org)
Have you tried "where recno IS NULL"?
