RE: Unused column names

Chaim,

Have you looked at the USER_UNUSED_COL_TABS or DBA_UNUSED_COL_TABS view?

Lex,
You've answered my question. To answer yours: we had an import that failed
with an "imp-00020 long column too large for column buffer error". The
export had no long columns but there was a note on metalink that pointed to
unused columns (and directmode export) as a possible explanation. Sure
enough the database that provided the export file had a table with unused
columns. 
We're a distributed environment with more than a couple of sites. Only one
site has the unused columns. That triggered the dilbert syndrome which
resulted in my question to the list... chaim

Chaim,

why would you like to know them? those columns are lost forever anyway,
except when using regular recovery techniques -- but then the names come
back with the recovery :-)

Kind regards,
Lex.

is it possible to identify the original names of columns that are no longer
used (as in ALTER TABLE SET UNUSED COLUMN cname)?

thanks,
