I would recommend that you create a stored
function/procedure that returns the "default" that you
want it to return, and execute a call to that, rather
than executing "select test.now". The statement "select
test.now" doesn't even seem to be valid sql. Bear in
mind that I have no idea what you are talking about so
my advice might not be helpful.
I have timestamped database backups and timestamped
schema update files so that my database load script
knows which schema updates to apply when loading an old
database backup (i.e. anything whose timestamp is later
than the timestamp of the backup), which seems like it
might be related to what you are after, but I don't
understand the idea of a "default" date. The "date" for
my schema is always the present so as to match the
corresponding software in its current state.
Perhaps you can explain in more detail what you are
after.
