Hi. I need extract some metadata from database. I need some view, or
procedure that generate rows with field name, field type and size, and,
if possible, if field is primary key. I want extract this information
from data dictionary, but the hardest thing is resolve the field type
and size, like VARCHAR(20) or NUMERIC(8,3). What RDB$ tables I need to
do this?

Can anybody help me with this?

TIA,

Dufloth.
