Disadvantages of selecting higher than required data class & size category


Hi !

What are the disadvantages of defining a table with a very much higher data class and size category of the really needed??

In fact, the table already exists has some data. All have size category 0, but because of the contents, they should have 2 or 3. Can we just put 9 and forget about it? how much space will be reserved in the database for those over defined tables? that could be wasted...

We are using ORACLE 10.

Thanks !
