Retrieving BLOB and Converting it to CLOB in Apex

Question

Hi,
I am using Apex to upload a BLOB file (csv) and in my PL/SQL function, I convert it into a CLOB. However it doesn't read all the lines. Any advice? Thanks.
Here's the function I used to convert BLOB to CLOB.
function convertBlob(
B IN BLOB
return clob is
c clob;
n number;
BEGIN
if (b is null) then
return null;
end if;
if (length(b)=0) then
return empty_clob();
end if;
dbms_lob.createtemporary(c,true);
n:=1;
while (n+32767<=length(b)) loop
dbms_lob.writeappend(c,32767,utl_raw.cast_to_varchar2(dbms_lob.substr(b,32767,n)));
n:=n+32767;
end loop;
dbms_lob.writeappend(c,length(b)-n+1,utl_raw.cast_to_varchar2(dbms_lob.substr(b,length(b)-n+1,n)));
return c;
END;

Answer 1

use dbms_lob.getlength rather than length to get the length of the blob.
Nothing else obvious stands out, but should be plenty of examples in pl/sql forum and I know there is an example of this on the web. BLOB to CLOB?
