Hi All,
My question relates to 7.3.3 and 8.0.4.
In a large table, if number(38)'s are used
but only populated with, say, 10 digits is
any space wasted. Also if this number is later
updated to, say, 20 digits could this cause
row chaining - or at best data fragmentation
within the block?
Same question on varchar2 actually, I heard
that over vachar2(255), 2 bytes are needed to
store the length, so if you store less than 255
chars in a, say, varchar2(300) then you waste
two bytes per row.
Can anyone verify this?
Thanks
Steve
