Stuart,

It does not show BLOBs in preview, but during export - yes - it supports Firebird BLOBs and "small BLOBs" introduced in recent Interbase versions.

Not to be rude or anything, but does FirstAID Extractor decrypt all types of BLOBs?

    Hi Stuart,

    Download FirstAID from www.ib-aid.com <http://www.ib-aid.com>, run
    FirstAID Extractor and open your database. It "decrypts" data from
    Firebird database using its internal structures and shows you the
    values of fields in tables' records.

    OK, but version numbers tell me nothing. What I am looking for is
    an explanation of how Firebird (the package) can tell which bytes
    belong to which fields. Somehow Firebird must be able to tell the
    difference between the following two records:

    FirstName     LastName
    'Jim'               'Starkey'
    'Jim Starkey'  ''


    It may well be that it was coded in the Interbase days and has
    not been looked up until now. Or maybe it's the blob in the
    "RDB$DESCRIPTOR" field, in which case I do not know how to decode
    it into text.

        No for all questions. The record is a) run length encoded and
        b) contains a format version number that must be looked up in
        rdb$formats.

                Hello Firebird Developers:
                Pardon  me, but I found the structs I was looking for
                in the source code (it was hard!). I don't want to
                bog you down with novice questions, but I want to
                know two things:

                1. Is there a field (e.g., "fp_field_type") in the
                field or record header that would indicate the field
                type?
                2. What indicates the end (or, alternatively, size in
                bytes) of a non-final field in a record with two or
                more fields?

                Thank you!

                Stuart
