Hi list,
I've a function:
SELECT D.typname as domname, format_type(b.oid,NULL) as dombasetype,
D.typlen, D.typtypmod, D.typnotnull, D.typdefault, D.typndims, D.typdelim, C.consrc
FROM pg_type D
JOIN pg_type B ON B.oid = CASE WHEN B.typndims > 0 then D.typelem ELSE D.typbasetype END
JOIN pg_namespace N ON N.oid = B.typnamespace
JOIN pg_constraint C ON (D.typname || '_check') = C.conname
WHERE D.typtype = 'd' AND D.typnamespace = 2200::oid ORDER BY D.typname;
that returns (not complete):
domain name | domain type | length(+typlen) | not null? | default | constraint
dn_percent_vat | numeric | 458762 | t | 0.196000 | ((VALUE > -0.000001) AND (VALUE < 1.000001))
As 'length(+typlen)' returns 20 for 'varchar(16)', and min length of type
'character varying' is 4, 20-4=16 check ok.
However, I don't see how to extract 'numeric(7, 6)' from '458762' (IF it
should be extract from that value!)
How can I do that?
