The way I usually do it is to put the blob in a separate table/entity  
-- I would call this the "best practice".  Another possibility is to  
move the blob out of the database altogether.

If neither of those grabs your fancy, then you could create two  
entities in EOModeler, one which includes the blob and another that  
doesn't (both pointing to the same table -- yes, that's allowed).  Of  
course, you'll have to do some gymnastics in code to make sure you  
don't get the two confused...
