Hmmm, this message is one month old, howerver I believe I was thinking of tables having
fixed length records, like dBase, Access, I don't know about others. They need to know the number
of records in order to add a new one more easily... and precisely to be able to return the
number of records without having to browse the whole file.
Also, the b-tree or other algorithms used in idexes implie that they know the number of records.
In any dbf file, the number of records is a long integer which can be found at address 0004.
It is the value returned by the reccount function.
In other databases, I don't know where it is, but if they don't have such a feature, I wonder
why it is worth paying so much to have them ;-)
>>Why must it do so? Isn't that a lot of overhead?
A lot of overhead to maintain a 4 bytes count in a many megs file ? C'mon ;-)
