Hi, I want to insert data in my table and I want to insert the rows, which don't violates the unique contraint of my id. I'm using a 64bit hash for my it. If I do one insert statement, which inserts many rows it doesn't do anything if one row violates the unique contraint. Is there a faster way than using multiple insert statements? Janek
You could: create table junk (like main); copy to junk ...; create index junkpk on junk(uid); -- _not_ a unique index, optional analyze junk; select uid, count(*) from junk group by uid; -- do something about the dups insert into main select * from junk; drop table junk; -Andy -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
