Hello Sándor, All the tables (~400) are loaded from an export in CSV like format done from the same Sybase ASE database with this commands for any table: 08:08:00 TRUNCATE TABLE acq_haushalt ; 08:08:00 TRUNCATE TABLE 08:08:01 \COPY acq_haushalt FROM '/home/sisis/guru/sisisDBsrap14/CC-acq_haushalt.load' WITH ( NULL '' , DELIMITER '|' ) 08:08:01 COPY 2862 and afterwards we have to adjust the serials to the highest used value with the shown command: > > > > /* table: acq_haushalt */ > > DO $$ > > DECLARE > > max_id int; > > BEGIN > > if to_regclass('acq_haushalt') is not null then > > SELECT INTO max_id GREATEST(COALESCE(max(hnr), 0),0) + 1 FROM > > acq_haushalt; > > RAISE NOTICE '% % %', 'acq_haushalt', 'hnr', max_id ; > > EXECUTE 'ALTER SEQUENCE acq_haushalt_hnr_seq RESTART ' || max_id::text; > > end if; > > END $$ LANGUAGE plpgsql; It's output (for this table) was: NOTICE: acq_haushalt hnr 3183 which is correct because it matches the highest value +1 of 'acq_haushalt.hnr'. matthias -- Matthias Apitz, ✉ guru@xxxxxxxxxxx, http://www.unixarea.de/ +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub May, 9: Спаси́бо освободители!
