Simple Question: How to find out, how many bytes of the disk some data
in a table requires ?
There are several things i do not know:
* how many bytes does one column of a certain datatype (NUMBER(n,m),
VARCHAR2(n), DATE, ...) require ?
* is there (and if, how large) some overhead for each column that is not
null ?
* how large is the overhead for an entire row ?
I ask my question for several reasons:
* curiosity
Has someone experience, heard of a tool or so ?
Thanks in advance
