I think it is to accommodate sys.attrcol$.name column ...
In our 9202, it has references to Spatial objects ...

Subject: this doesn't look right
As part of the process of making sure that null/not null constraints
are consistent across development/staging/production, I'm looking at
the dba_cons_columns table.
Now, as far as I know, column_names are limited to 30 characters,
correct? If so, why is the column_name column in dba_cons_columns
(9.2.0.1) a varchar2(4000)? I realize that the "extra space" isn't used
and is never allocated so it's not like this is wasteful.
But it's inconsistent with everything else, since dba_tab_columns has a
column_name column of varchar2(30).
anyone know why this is like this?
Rachel
