Walter:
You use the VSIZE() function. And you are right about 1 not taking the
same amount of size as 9. 1 uses 2 bytes and 9 uses 4.
SQL select vsize(1), vsize(9) from dual;
VSIZE(1) VSIZE(9)
24

Hi,
How do I calculate the amount of physical space
required for storing a number? (i.e. NUMBER,
NUMBER(5), NUMBER(10,5), etc.) I believe Oracle uses
2's compliment for storing numbers. A value of 1
does not seem to take up the same amount of space as
9.
TIA!
