| Subj: || || Re: Adding New Compression Values to Compressed Field |
| From: || || Victor Sokovin |
| ||Is there any way to add new compression values to a field that is already compressed, without having to copy the table into a new table
that has the compression redefined.|| |
What you could do is add a new column with the new list of compressed values, populate it with the data from the old column, drop the old
column and then rename the new column to the old name. All these actions are readily available in ALTER TABLE.
I believe this is the most economical way of doing this.
