9.13 Updating Collection Members
You can update collection members by calling the UPDATE_MEMBER procedure and referencing the desired collection member by its sequence ID. The UPDATE_MEMBER procedure replaces an entire collection member, not individual member attributes. 
                  
Use the p_clob001 parameter for collection member attributes which exceed 4,000 characters.
                  
To update a single attribute of a collection member, use the UPDATE_MEMBER_ATTRIBUTE procedure.
