Here you should better use update master_items set feedback_to_de = 'Yes' WHERE feedback_to_de <> 'Yes' OR update master_items set feedback_to_de <> 'Yes' WHERE feedback_to_de IS DISTINCT FROM 'Yes' depending on the column nullable. regards, Marc Mamin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
