How do you recover the contents of a document once its been erased

Question

Hi Pages community
Any idea how to recover the contents of a document once the contents has been erased but the document still exists?
I already reset the Ipad using an Icloud backup from June 11th.
Thanks
Beth

This is modified code. I think it works.
declare
a blob;
b blob;
d number:=1;
e number:=1;
f number:=1;
begin
select module_floorplan into a from tblob where seqno = 100;
select module_floorplan into b from tblob where seqno = 100;
e:=length(a);
d:=length(b);
select dbms_lob.compare(a,b,dbms_lob.lobmaxsize,d,e) into f from dual;
if f = 0 then
   dbms_output.put_line('Same --> '||to_char(f));
else
   dbms_output.put_line('Diff --> '||to_char(f));
end if;
exception
     when others then
          dbms_output.put_line(SQLERRM);
end;
