Subj:   Re: Compress Null value
From:   Pluebell, Fred

If you compress at least one (non-NULL) value, then NULLs will be compressed also - whether you list NULL as a value to be compressed or not. If you don't compress any other values but you have a significant percentage of the rows with NULLs, then specify COMPRESS NULL explicitly.
