Re: BLOB column/field data type?

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Not really...

Certain files have signatures you could try to use, but that's no guarantee
as stream files, unlike IBM i objects don't have an enforced type.
https://en.wikipedia.org/wiki/List_of_file_signatures

The application storing the blob should be storing some indication of what
the blob is.

Particularly since it's apparently storing multiple types.
