Thanks for clarifying! This is very useful info, especially the
ibexpert.net site.
Is there a Firebird site that provides details such as CHAR and VARCHAR max
sizes, pageSize size options, etc.?

Cases when pages of smaller size have a speed advantage are very special and
Doesn't the page size definition as per a database depend on one designs their

In any event, here is what the Developer Guide for version 3.0 of Firebird
states...

It doesn't matter because Firebird client deliver length of VARCHAR in
native endiannes
and for the rest there are API functions to convert
What is the max page size for Firebird 3?
Also, could you clarify a page? Does each record consume a page, or are
could there be multiple records on a page?

For a minor clarification. In the electronics world, we specify the
sequence of multiple bytes with the word "Endian".
Assume the hex number is 0x1A2B. For Big Endian, the 0x1A is first. For
Little Endian, the 0x2B is first. The previous comments indicate that
Firebird is Litle Endian.

Telling us how other engines work is not very relevant when discussing
Firebird, and when the **internal
Good evening,
I'm blocking on a series of problems that you certainly have the
solution for.
When I change the value IPv6V6Only "0 | 1" "False | True" I have a
socket error in Firebird.log and no way to connect.
If I try embedding, I always have the error
"operating system directive access
Excellent!
A big thank you for your work

How "all database engines operate" is irrelevant here. You are wrong in your
assumption
how Firebird

If there information is incorrect, you should contact them to have it

Steve Naidamast

What do you mean I am wrong? I have merely re-iterated how all database
engines I have worked operate.
And what you are saying is that a CHAR field in Firebird acts in the same
manner as that of a VARCHAR field. If that were the case there would be no
difference in how they are used and
< INSERT INTO LOG(WAS) VALUES ('blabla');
causes the error:
Statement failed, SQLSTATE = 23000
validation error for column "LOG"."ID", value "*** null ***"

Optimum page size doesn't depend on data but on application usage.
