Does empty table cell cost storage or memory space?
647607Jun 30 2008 — edited Jun 30 2008It has been a while from last database design. I have some kind of impression that even if a cell in a table does not have data in it Oracle will still allocate space for it for certain data types. Is this right?
If this is right, is it only for data storage on the disk or even in the memory? What at the data types?
Can anyone help me on this?
