或者我也试过这段代码
update "Recon".ship_error
set shipping_fee = case
when settlement_date > '2015-01-01'
then
--shipping_fee = case
when shipping_zone = 'NA' and order_status !='return_completed' then 0
when shipping_zone = 'NATIONAL' and total_weight <= 0.5 and order_status !='return_completed' then -55

when shipping_zone = 'NA' and order_status !='return_completed' then 0
