Using the DOMAINS system table, you can determine the following database information, among other things:
·
All domains and
their comments defined for data type DATE
SELECT owner,
domainname, comment
FROM DOMAIN.DOMAINS
datatype = 'DATE'
·
All
your own domains in which a default value was agreed
SELECT domainname,
datatype, len, dec, default
FROM DOMAIN.DOMAINS
WHERE owner = user
AND default IS NOT NULL
