Just adopting William's advice and changing to this:
(coalesce(REGEXP_REPLACE(broker_mc::text, '[^0-9]+', '', 'g')::numeric, 0)),
(coalesce(REGEXP_REPLACE(carrier_mc::text, '[^0-9]+', '', 'g')::numeric,
0)),
(coalesce(REGEXP_REPLACE(freight_forwarder_mc::text, '[^0-9]+', '',
'g')::numeric, 0)),
has resolved the problem. Thank you, William and David! Learning a lot
here. Appreciate all the help.
Sam
