Обсуждение: copy into serial field with auto_increment

Hello,

i've got a textfile of data separated by '|'. One of the fields in my
table is a serial (auto_increment) field.
When i import the data with the copy command i get duplicate key error.
The key is the serial - field.
I recognized that the copy command doesn't auto_increment the serial
field. I come from mysql and pushed a 0 into the serial field. But it
doesn't work. I tested it with an empty field, but it failed to.
How could i make it work ??

Thanx for every help

It's not clear to me whether your error is during COPY or afterwards.

If it is during COPY, edit your textfile and assign unique values to
each row.


If it is afterwards, use 
 SELECT setval('sequence_name', SELECT max(serial_field) FROM table);

to set the sequence value.  (You probably have to be running 7.1 to use
a sub-select like that.)
