  1. Postgres View DDL

    Sam Stearns <sam.stearns@dat.com> — 2024-10-16T21:33:37Z

    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

    Sam Stearns <sam.stearns@dat.com> — 2024-10-16T21:42:28Z

    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;

William Alves.

  5. Re: Postgres View DDL

    Sam Stearns <sam.stearns@dat.com> — 2024-10-16T23:07:29Z

    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
