Re: [firebird-support] Is it save to append some data at end of the binary firebird database file?

Hi, i am really surprised – why reinvent the wheel? All people use table with version information and this work years. Table have benefit – you can include version description (what’s new). At application start or installer – you check if db is up to date or if instaler is not older than

Re: [firebird-support] Is it save to append some data at end of the binary firebird database file?

What you can do is inspect Firebird structure and search for an unused area. Documentation about this can be found at http://www.firebirdsql.org/manual/fb-internals.html By example if you check http://www.firebirdsql.org/manual/fbint-standard-header.html Pag_checksum: Two bytes, unsigned. Bytes

That is very dangerous to do, the same bytes might be reused differently in a newer ODS. Either use a normal Firebird table to store version info, or do it outside of the database. Do not hack things in the internal structure. Mark - Reply message - Van: "Fabiano Kureck

The same could be accomplished by creating a “Application_SchemaVersion” SP which would return the necessary details. The advantage would be that no search thru the domain would be required. Sean From: firebird-support@yahoogroups.com [mailto:firebird-support@yahoogroups.com] Sent: December

On Windows, all files can have alternative streams with additional data. It is a form of hidden metadata that is attached to the main filename. Mark - Reply message - Van: "Tim Ward t...@telensa.com [firebird-support]" Aan:

[firebird-support] Is it save to append some data at end of the binary firebird database file?

Hello, My main intend is to add some version information to a firebird database file, since I will use firebird as embedded database and installers/update mechanism will need this information. The information should be available platform independent and I would prefer a solution not needing
