Re:RE: Renaming a Column

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 insert the data from the old table into the new one.

If you want to try the "backdoor" method of changing the value in sys.col$ do so on a development box, preferably one that is not used actively for development and then only after a cold backup and don't ask the list for help when you fat finger it. Cause the flame is going to be HOT!!!

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 to flame me if i'm wrong(it does happen but rarely) :)
