Hello Dunbar

Thank you for answering me.

Yes, I'll buy the supplement, evidently I'll need it.

I am a Systems Analyst and own a software's development business so
everything I can read about Firebird will be good for me. But I don't like
to read out of date versions, time is always short, and we need faster
possible ways to do things. As an example, we had shorten our code with the
"update or insert" instruction. It is now more short, more simple and more
easy to read and understand. That's the kind of things that I am looking
for.

As an idea, a book covering version 2.5 and with many short examples and
"how to do" will be very useful, so your readers will learn SQL and
Firebird.

Greetings.

Walter.
