question - she even said don't do it except in test.

Hi Kirti,
Assuming that your post was not "tongue in cheek", while I don't endorse the
procedure, the Ixora web site has a note about a potential problem with doing
this and how to work around it at http://www.ixora.com.au/q+a/dd.htm#31_08_1999.
Please note the disclaimer there too.
@ Regards,
Been there, done it. It's dangerous. Don't ever do it.
I was lucky and was able to reverse the changes. I know
and Oracle instructor who was not so lucky and lost a database.
I've heard of other people doing this and it worked properly.
It's usually a bad idea to mess with the data dictiona
Oracle will absolutely not support your database if you ever reveal to them
that you've directly hacked the data dictionary. And with good reason.

Have you personally done this in your test database (and may be in your
production database)?
Are there any 'side effect' as to Oracle may not support any problems it may
create down the road?
Or this is a perfectly safe operation to 'just do it' ? If so, what type of
'risks' it might have?

I didn't find it any of my docs for 8.1.7 either. Is renaming a column
getting confused with dropping a column?
For renaming columns, one has to wait till 9i is a reality, I was told

I know someone asked how many of us would use the "backdoor methods" to rename
columns. I believe the answer is only the foolhardy & those with suicidal
tendencies. The only way to "rename" a column, without reverting to the view
thing, is to create a new table with the correct definition & then
Below are the steps and examples to rename a table:
1. create a view of the table which you want to rename its column

NameNull?

Hi All
I think I did send one out earlier. Don't bite.
You can't rename a column. The combatibility parameter issue I was thinking
of has to do with when you want to drop a column in 8i. That I know, has to
be greater or equal to 8.1.0 when you want to drop a column
Sorry again

Ok i'll bite, i try to keep up with the new features and i'm looking at
8i(8.1.7) docs right now and i dont see it, would you like to elaborate?
you can rename a table, rename a partition but NOT rename a column, this
has been on the wish-list for many years just like drop column was.
Feel free
Sorry sorry

Yes you can rename a column in 8i, it just depends to what value your
compatibility parameter is set

It's not possible to rename a column.You can instead

Or you have to create a new table
if it is oracle 815 onwards
insert new column in the table.
insert data into new column from the old column in the table
alter table drop column

One of the ways:
create table newtable (newcolumn1,newcolumn2,newcolumn3,...)
as select * from oldtable

rename newtable to oldtable;
