how to use nextval() - Mailing list pgsql-sql

Hello there

I have an idea how to solve my problem on copy a record to a new one in the
same table. To do so I need the next value for the primary key.

Using :

select nextval('pk_auftrag') as nextkey from auftrag;

I get an error like : Relation pk_auftrag does not exist !

Thanks for any help ... jr
