Thx for the quick response Helen.

I guess I'm going to have to add and configure a separate TIB_Query
specifically for the table in which I need to store the blobs. This way I
can pre-define the fields in the design-time editor and use it as you
mentioned. You see, currently I only use the single TIB_Query component
throughout the whole application and I never supply it with any fields, I
simply add an SQL statement to it's SQL property and then execute the query.

Best Regards,
Don Schoeman

Pass the contents of the device file into a TStream derivative, then assign
the stream to the blob. There are examples in the IBO help under
CreateBlobStream().You can do it the other way around, too, if you want to
save the blob data to a file.
