BLOB Filters


A Binary Large Object (or BLOB) is a collection of binary data stored as a single entity in a database management system. BLOBs are typically images, audio or other multimedia objects, though sometimes binary code is stored as a BLOB.

 

BLOB filters are routines for Blobs. They translate Blob data from one type to another, i.e. they allow the contents of Blob subtype X to be displayed as subtype Y, or vice versa. These filters are ideal tools for certain binary operations, such as the compression and translation of Blobs, depending upon the application requirements.

 

Blob filters are written in the same way that UDFs are written, and are generally part of standard libraries, just as UDFs are.

 

 

BLOB Filter Editor allows you to define BLOB filter properties. It opens automatically when you declare a new BLOB filter and is available on editing an existing one.

 

To open a BLOB filter in BLOB Filter Editor, double-click it in the DB Explorer tree.
