Subj: | | Verifying Column Compression |
|
From: | | Tony Howe |
Is there anyway to tell if a new column being added to the end of a table that's marked as NOT NULL DEFAULT ' ' COMPRESS ' ' is actually
getting compressed.
I do an INSERT/SELECT from CURRENT to NEW table and new table has 15 new columns added to the end define as above. I usually don't see
an increase in DASD use, but this time the table size increased by 54 GB as if compression didn't happen on the new columns.
Thanks in advance, Tony.
