Note that NUMERIC is meant for
- really large numbers with lots of digits
- or controlled precision and rounding (ie, order total isn't
99.999999999999 $)
Accordingly, NUMERIC is a lot slower in all operations, and uses a lot
more space, than all the other numeric types.
I see many columns in your table that are declared as NUMERIC but should
be BOOLs, or SMALLINTs, or INTs, or BIGINTs.
Perhaps Oracle handles these differently, I dunno.
