Hi everybody,
is there any way to have an estimate of the disk space used by a table?
Any system table to query, or something like this?
Using record size * record number is not always possible, if you use
a TEXT field the size used is 4+n, so it's dependent on inserted data.
best regards
Andrea Aime
