Got it. UPDATE app_id_800 SET cal_byte_w_err = (CASE WHEN cal_byte_w_err.value=1 THEN 't'::boolean ELSE 'f'::boolean END) FROM cal_byte_w_err WHERE app_id_800.timestamp BETWEEN '2004-01-01 00:00:00' AND '2004-01-01 00:00:05' AND app_id_800.timestamp = cal_byte_w_err.timestamp; Have a good weekend all.
