It's been years since I've posted but I'm really stumped on this one. I have an Oracle BLOB column in a table with about 4.3 million rows. I have a parent table which links to the 'image table' in a one to many relation.

Parent_tab		image_tab
---------------                 ---------------
PK column		link_id
link_id		 	Blob (containing pdf file)

I'm thinking of using 2 cursors in PL/SQL looping though the parent_tab  and then comparing all of the associated blobs to each other. (I think it's or something like that )

Is this a logical way to go ? I'm nervous about starting down the PL/SQL path ( as I'm very rusty) and then find that is the wrong tool.
