Hi! Testing RDB$BLOB_UTIL I saw that seek works only after blob is materialized to a field.
This looks like a bug. I can create and close a blob, then open its id and read from it before materialize. But I can't seek correctly in the opened blob before it's materialized to a field. Is this a know bug? Adriano Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
