Hi, I want to delete duplicates in my table. I've dropped the unique constraint to insert my data. My id value is a hash calculated witch the values of the two other columns. So I want to delete all columns, which are indentical, but keeping one. DELETE FROM table t1 USING table t2 WHERE t1.id = t2.id AND t1.ctid > t2.ctid But the oids aren't unique enough. What else could I do? Janek -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
