I see there's a way to convert to a roman numeral using
to_char(10,'RN') will give you 'X'.
How can i go the other way?  i was looking through the docs, but i
couldn't find the right arguments to give to to_number('X',???) to get
10.

regards,

--brian

You cannot, but it is on a "TODO" list within the source code.

Until then, you may want to take a look at the perl module Math::Roman
