RE: Renaming a Column
From the 9i New Features Doc - Online Data Evolution In this new architecture the contents of the table are copied into a new table. While the contents are copied, the updates to the original table are tracked by the database. After the copy completes, the updates are applied to the new table. Once the updates are applied, indexes can be created on the new table. After the indexes are created, any additional updates are applied and the result table replaces the original table. The table is only locked in exclusive mode at the beginning and end of the operation, when the dictionary data is updated. Using this new architecture, any physical attribute of the table can be changed online. The table can be moved to a new location. The table can be partitioned. The table can be converted from one organization (e.g. heap) to another (e.g. index organized). Additionally, many logical attributes can be changed. Column names, types, and sizes can be changed. Columns can be added, deleted, or merged. The primary restriction is that the primary key of the table cannot be modified. -Original Message- Kirti Sent: Wednesday, February 14, 2001 01:27 To: Multiple recipients of list ORACLE-L I didn't find it any of my docs for 8.1.7 either.

Hi, The suggestion till yet provided are the correct ones and safest. But try this in your test database, get you table id from sys.obj$ table.

RE: Renaming a column
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 dictionary unless instructed to do so by OWS.
