Hi, I have two questions about the copy (SQL or not) command. If I understood it well, \copy is just an interface to the SQL copy command. First of all, it stops if a unique index rule is broken. This means that one can not insert a set of datas using copy, and relying on the database's core to drop off the non unique entries. Am I wrong ? Is there any solution to force copy inserting all good entries, and dropping the bad ones (e.g: in case of doubles) without stopping it's execution ? Second question is : I have a very simple table with a sequence : create sequence uidseq start 1; CREATE TABLE users ( uid int4 default nextval('uidseq'), -- Primary Key login varchar(15) ); Can I use copy to fill in my users table, and relying on the system to affect the right sequence numbers ? e.g : If I do : INSERT INTO users (login) VALUES ('test') ; Then, the right sequence number will be given. But, if I import (copy) a file with the following format : \t<login> where \t stands for a tab sign, and using : copy users from '/tmp/users'; Then, all my users get an uid of 0.
