Howdy,
I have an Oracle view that's been converted for Postgres. This block of
code in the Oracle view DDL:
TO_NUMBER (NVL (REGEXP_REPLACE (broker_mc, '[^0-9]+', ''), 0)),
TO_NUMBER (NVL (REGEXP_REPLACE (carrier_mc, '[^0-9]+', ''), 0)),
TO_NUMBER (NVL (REGEXP_REPLACE (freight_forwarder_mc, '[^0-9]+', ''), 0)),
has been converted for Postgres as:
(coalesce(REGEXP_REPLACE(broker_mc, '[^0-9]+', '', 'g'), 0))::numeric ,
(coalesce(REGEXP_REPLACE(carrier_mc, '[^0-9]+', '', 'g'), 0))::numeric ,
(coalesce(REGEXP_REPLACE(freight_forwarder_mc, '[^0-9]+', '', 'g'),
0))::numeric ,
which is throwing the following error:
ERROR: COALESCE types text and integer cannot be matched
LINE 43: ...ce(REGEXP_REPLACE(broker_mc, '[^0-9]+', '', 'g'), 0))::numer...
^
I have been looking through:
https://www.postgresql.org/docs/current/functions-conditional.html#FUNCTIONS-COALESCE-NVL-IFNULL
https://www.postgresql.org/docs/current/typeconv-union-case.html
but I'm not seeing a way to resolve it. Would anyone be able to advise how
to correct this for Postgres, please?
Thanks,
Sam

Tried changing to this:
(coalesce(REGEXP_REPLACE(broker_mc::numeric, '[^0-9]+', '', 'g'), 0)),
(coalesce(REGEXP_REPLACE(carrier_mc::numeric, '[^0-9]+', '', 'g'), 0)),
(coalesce(REGEXP_REPLACE(freight_forwarder_mc::numeric, '[^0-9]+', '',
'g'), 0)),
but that throws this error:
ERROR: function regexp_replace(numeric, unknown, unknown, unknown) does
not exist
LINE 46: (coalesce(REGEXP_REPLACE(broker_mc::numeric, '[^0-9]+', ...
^
HINT: No function matches the given name and argument types. You might
need to add explicit type casts.

Both parts of the coalesce need to be integer. Therefore:
regexp_replace(…)::integer
In short, the output of the text manipulation better be something that can
be cast to integer if you want coalesce to produce an integer.

Hello Sam.
I think you want this:
SELECT COALESCE(regexp_replace('abc12345'::TEXT, '[^0-9]+', '', 'g')::NUMERIC, 0);
The coalesce need the same type from origin field, or you cast the result from regex to interger/numeric etc, or you use cast ‘0’ instead of 0;
Regards,
William Alves.

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.
