Hello there!

I'm trying to use a blob filter in an Interbase Database. So
far,I have coded the function in a dll, declared the function as a
blob filter in the database and created a table that holds 3 fields,
an Id, a Blob subtype -1 and a Blob subtype -2. The Blob filter is
inteded to pass from blob subtype -1 to -2. How do I call the
filter? do I need to coded something in the application that
connects to the database? Any help will be greatly appreciated.

Thanks
