SQL query to return the image attached to Related Materials

Summary:

Hi

I need help building a SQL query to return the image attached to Related Materials. In a query we can bring the image extension, but not the image.

SELECT wlf_learning_items_f.learning_item_id
   ,wlf_learning_items_f.learning_item_number
 ,wlf_li_relations_f.relation_id
 ,fad.pk1_value
 ,fad.attached_document_id
 ,fdt.document_id
 ,fdt.title
 ,fdt.file_name
 ,fad.creation_date
 FROM fnd_attached_documents fad
   ,fnd_documents_tl fdt
 ,wlf_learning_items_f wlf_learning_items_f
 ,wlf_li_relations_f wlf_li_relations_f
 WHERE fad.document_id = fdt.document_id
