How do I use Blobs with JayBird?

Blobs are Binary Large OBjects. Blobs are used to store blocks of binary data of varying size in the database. An example would be a database table to store gif or jpeg images for a photo album program.

Such a program could be written using the database to store file names of image files to be loaded from disk, but this could easily be corrupted if a file name were changed, a file inadvertently deleted, or the database moved to a system with different file naming conventions. Blobs allow the binary image data to be stored, retrieved, backed up, and migrated like any other database data. The Interclient JDBC driver did not implement many of the blob handling methods in the JDBC interfaces.

So, the programmer had limited tools for using blobs with Interclient. That is no longer the case with JayBird. If you come across old code or help files dealing with blobs and Interbase/Interclient, be aware that it may be outdated and easier ways of dealing with blobs are available with JayBird.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
