File Upload Download Application- Query cannot be parsed within the Builder

Question

Posting for those who encounter this problem.
In the section "Store the Document in a Custom Table", you will encounter a problem with the SQL:
if ( :P2_FILE_NAME is not null ) then
insert into file_subjects(id,NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
select id,:P2_FILE_NAME,:P2_SUBJECT,blob_content,mime_type
from wwv_flow_files where name = :P2_FILE_NAME;
delete wwv_flow_files where name = :P2_FILE_NAME;
end if;
The problem is that the BLOB_CONTENT column has not been initialised with and empty BLOB locator.
I modified the SQL as follows. If there is a better way of doing this please post.
if ( :P2_FILE_NAME is not null ) then
insert into file_subjects(id,NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
select id,:P2_FILE_NAME,:P2_SUBJECT,EMPTY_BLOB(),mime_type
from wwv_flow_files
where name = :P2_FILE_NAME;
insert into file_subjects(blob_content)
select blob_content
from wwv_flow_files
where name = :P2_FILE_NAME;
delete from wwv_flow_files where name = :P2_FILE_NAME;
end if;

Does your parsing schema have direct granted privileges to execute the function or privileges via a role? If it is through a role, you need to directly grant execute on the function to your parsing schema.
