XML data from BLOB to CLOB - character set conversion

Hi All,
I'm trying to solve a problem with a character set conversion in PL/SQL in the following scenario:
1. source is an XML as a BLOB variable.
2. target is an XML as a CLOB variable.
3. the problem I have is the following:
- database character set is set to UTF-8
- XML character set could be anything (UTF-8, ISO 8859-1, ISO 8859-2, ASCII, ...)
- I need to write a procedure which converts the source BLOB content into the target CLOB taking into account the XML encoding and converts it into the DB default character set (UTF8).
I've been able to implement a simple conversion function. However, this function expects static XML encoding ISO-8859-1. The main part of the function looks as follows:
buffer := UTL_RAW.cast_to_varchar2(
UTL_RAW.convert(
DBMS_LOB.SUBSTR(source_blob_variable, 16000, pos)
, 'American_America.UTF8'
, 'American_America.we8iso8859p1')
Does anyone have an idea how to rewrite the code to handle "any" XML encoding in the source BLOB file? In other words, is there a function in Oracle which converts XML character set names into Oracle character set values (ISO-8859-1 to we8iso8859p1, UTF-8 to UTF8, ...)?
Thanks a lot for any help.
Julius

I want to pass a BLOB to some "createXML" procedure and get a proper XMLType in UTF8 character set, properly converted from whatever character set is the input in.As per documentation the generated XML has always the encoding set at the client side depending on NLS_LANG (default UTF-8), regardless of the input encoding, so I don't see a need to parse the PI of the XML:

Converting a blob to clob

Hi,
Has anybody been successful in using the DBMS_LOB.ConvertToClob procedure. It's giving me "invalid lob locator specified" error.
here's my code
create or replace function convert_blob_to_clob(p_file in varchar2) return clob is
v_file_blob blob;
v_file_clob clob;
v_file_size integer := dbms_lob.lobmaxsize;
v_dest_offset integer := 1;
v_src_offset integer := 1;
v_blob_csid number := dbms_lob.default_csid;
v_lang_context number := dbms_lob.default_lang_ctx;
v_warning integer;
begin
select a.blob_content into v_file_blob
from txt_files a
where name = p_file;
dbms_lob.convertToClob(v_file_clob, v_file_blob,v_file_size,
v_dest_offset, v_src_offset, v_blob_csid,
v_lang_context, v_warning);
if v_warning = 0 then
return v_file_clob;
end if;
end;
Any help would be greatly appreciated
Thanks.

I figured it out...
here 's the new code..
create or replace function convert_blob_to_clob(p_file in varchar2) return clob is
v_file_blob blob;
v_file_clob clob;
v_file_size integer := dbms_lob.lobmaxsize;
v_dest_offset integer := 1;
v_src_offset integer := 1;
v_blob_csid number := dbms_lob.default_csid;
v_lang_context number := dbms_lob.default_lang_ctx;
v_warning integer;
begin
select a.blob_content into v_file_blob
from txt_files a
where name = p_file;
-- the following line solved it
DBMS_LOB.CREATETEMPORARY(v_file_clob, TRUE);
dbms_lob.convertToClob(v_file_clob, v_file_blob,v_file_size,
v_dest_offset, v_src_offset, v_blob_csid,
v_lang_context, v_warning);
if v_warning = 0 then
return v_file_clob;
end if;

Procedure to convert from long to clob

please need to procedure migrate data from long to clob,with variables
V_SRC_TABLE (LONG) to V_TRAGT_TABLE (CLOB)
SOURCE AND TARGET TABLE HAVE TWO COLUMNS
SOURCE_TABLE
VARACHAR2
LONG
TARGET_TABLE
VARACHAR2
CLOB

Hi,
assuming you want to convert data always from source_table to target_table knowing the column names, let's say:
SQL> CREATE TABLE source_table(col1 VARCHAR2(10), col2 LONG);
Table created.
SQL> CREATE TABLE target_table(col1 VARCHAR2(10), col2 CLOB);
Table created.You can just copy the data using SQL:
INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table;Or, as a procedure:
CREATE OR REPLACE PROCEDURE migrate_to_clob IS
BEGIN
EXECUTE IMMEDIATE 'INSERT INTO target_table SELECT col1, TO_LOB(col2) FROM source_table';
END;Hope it helps.

Converting from Blob to pdf problem

Dear all
I have a small problem i hope someone can help me with. I wrote a code that saves a pdf in a database as blob, but when trying to retrieve this blob back and show it as a pdf i had a problem.
When i tried to show the pdf it appeared as a long stream like the following
%PDF-1.6 %âãÏÓ 27 0 obj <> endobj xref 27 21 0000000016 0000 ...............etc.
so it has the same structure of my original pdf except that it's a long stream in only one line . The original pdf looks like the following
%PDF-1.6
%âãÏÓ
27 0 obj
<</Linearized 1/L 82015/O 38/E 6717/N 1/T 81428/H [ 716 197]>>
endobj
xref
27 21
............etc.
So if anyone can help to change that stream into a pdf again, i will really appreciate it. I attached the 2 files (the stream and the pdf).
Thanks in advance

You should save the PDF data to a file and loading that into your HTML content.

Blob to Clob function

I am using the below function to convert a CSV file with large data (say more than 100k records) . the below functions allows me to read not more than 350 records. Can any one help me with accepting the larger files ?
create or replace FUNCTION blob_to_clob (blob_in IN BLOB)
RETURN CLOB
AS
     v_clob CLOB;
     v_varchar VARCHAR2(32767);
     v_start     PLS_INTEGER := 1;
     v_buffer PLS_INTEGER := 32767;
BEGIN
     DBMS_LOB.CREATETEMPORARY(v_clob, TRUE);
     FOR i IN 1..CEIL(DBMS_LOB.GETLENGTH(blob_in) / v_buffer)
     LOOP
     v_varchar := UTL_RAW.CAST_TO_VARCHAR2(DBMS_LOB.SUBSTR(blob_in, v_buffer, v_start));
DBMS_LOB.WRITEAPPEND(v_clob, LENGTH(v_varchar), v_varchar);
          v_start := v_start + v_buffer;
     END LOOP;
RETURN v_clob;
END blob_to_clob;

Not sure why a BLOB is being used here. If you are processing just a CSV (text) file you shouldn't need a BLOB. You should be able to handle it directly as a CLOB. Could you detail more how you are using this function or what exactly your process is doing i.e. how is the data read in from CSV, where does it go, etc.?

Using blob or clob from db as document

I'm changing a working process to fetch an XDP document from a database rather than fetch from resources:// on the Adobe server. The DB2 database field containing the XDP is a clob data type. We were using blob. The services operations are:
- Foundation/JdbcService/Query Single Row   this fetches the XDP
- Foundation/SetValue/Execute   this converts whatever was fetched into a document variable
- Forms/FormsService/renderPDFForm   this merges the document with XML and produces PDF output
I'm unable to write the database field into a variable due to lack of choices. For instance there is no BLOB or CLOB variable type in the list of available types. When using STRING I get the following error:
Caused by: java.io.NotSerializableException: com.ibm.db2.jcc.b.ub
    at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
    at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302)
    at com.adobe.idp.dsc.util.CoercionUtil.toString(CoercionUtil.java:498)
When using XML I get the following error:
Caused by: com.adobe.workflow.WorkflowRuntimeException: Invalid location: /process_data/@clob_XDP_string cannot be stored for action instance: -1
    at com.adobe.workflow.pat.service.PATExecutionContextImpl.setProcessDataValue(PATExecutionCo ntextImpl.java:701)
When using OBJECT I get the following error:

    at com.adobe.workflow.pat.service.PATExecutionContextImpl.setProcessDataValue(PATExecutionCo ntextImpl.java:701)

Steve,
Going against DB2 doesn't work for me with a document variable type. It gives a coercion error.
I did solve my problem though from the following URL: http://groups.google.com/group/livecycle/browse_thread/thread/6c4b9156b52b71a7
JYates:
You can do this, but you have to use the Execute Script service -- at this time there isn't a deployable component for it.
Use this sort of script in the Execute Script service to read the PDF blob from the database and populate a Document variable.

Detecting character encoding from BLOB stream... (PLSQL)

I'am looking for a procedure/function which can return me the character encoding of a "text/xml/csv/slk" file stored in BLOB..
For example...
I have 4 files in different encodings (UTF8, Utf8BOM, ISO8859_2, Windows1252)...
With java I'can simply detect the character encoding with JuniversalCharDet (http://code.google.com/p/juniversalchardet/)...
thank you

Solved...
On my local PC I have installed Java 1.5.0_00 (because on DB is 1.5.0_10)...
With Jdeveloper I have recompiled source code from:
http://juniversalchardet.googlecode.com/svn/trunk/src/org/mozilla/universalchardet
http://code.google.com/p/juniversalchardet/
After that I have made a JAR file and uploaded it with loadjava to my database...
C:\>loadjava -grant r_inis_prod -force -schema insurance2 -verbose -thin -user username/password@ip:port:sid chardet.jarAfter that I have done a java procedure and PLSQL wrapper example below:
   public static String verifyEncoding(BLOB p_blob) {
       if (p_blob == null) return "-1";
       try
        InputStream is = new BufferedInputStream(p_blob.getBinaryStream());
        UniversalDetector detector = new UniversalDetector(null);
        byte[] buf = new byte[p_blob.getChunkSize()];
        int nread;
        while ((nread = is.read(buf)) > 0 && !detector.isDone()) {
            detector.handleData(buf, 0, nread);
        detector.dataEnd();
        is.close();
       return detector.getDetectedCharset();
       catch(Exception ex) {
           return "-2";
   }as you can see I used -2 for exception and -1 if input blob is null.
then i have made a PLSQL procedure:
function f_preveri_encoding(p_blob in blob) return varchar2 is
language Java name 'Zip.Zip.verifyEncoding(oracle.sql.BLOB) return java.lang.String';After that I have uploaded 2 different txt files in my blob field.. (first one is encoded with UTF-8, second one with WINDOWS-1252)..
example how to call:
declare
   l_blob blob;
   l_encoding varchar2(100);
begin
select vsebina into l_blob from dok_vsebina_dokumenta_blob where id = 401587359 ;
l_encoding := zip_util.f_preveri_encoding(l_blob);
if l_encoding = 'UTF-8' then
   dbms_output.put_line('file is encoded with UTF-8');
elsif l_encoding = 'WINDOWS-1252' then
   dbms_output.put_line('file is encoded with WINDOWS-1252');
else
    dbms_output.put_line('other enc...');
end if;
end;Now I can get encoding from blob and convert it to database encoding and store datas in CLOB field..
Here you have a chardet.jar file if you need this functionality..

Any help with be much appreciated.
I wrote the following but keep getting the following error: ORA-06502: PL/SQL: numeric or value error.

Blob to clob conversion when inserting as select?

I have a table with one row that has BLOB column. I would like to copy that row to a different table, with CLOB column data type. I’ve found this discussion (BLOB to CLOB? where some examples of stored procedures to convert blob to clob are used but I am unsure what should I use as input parameter to the blob_to_clob procedures listed in that discussion? Please advice.
Thank you very much for your time.
Daniel

The function by Richard Wiener {message:id=9646697} in the thread simply uses the procedure dbms_lob.converttoclob with a set of parameters defined in the function.
At my work we have created a similar function:
CREATE OR REPLACE function blob2clob (p_blob in blob)
   return clob
is
   v_clob     clob;
   amount         INTEGER;
   dest_offset    INTEGER;
   src_offset     INTEGER;
   blob_csid      NUMBER;
   lang_context   INTEGER;
   warning        INTEGER;
begin
   dbms_lob.createtemporary (
      v_clob,
      false,
      dbms_lob.session
   amount         := dbms_lob.lobmaxsize;
   dest_offset    := 1;
   src_offset     := 1;
   blob_csid      := nls_charset_id('AL32UTF8');
   lang_context   := 0;
   dbms_lob.converttoclob(
      v_clob,
      p_blob,
      amount,
      dest_offset,
      src_offset,
      blob_csid,
      lang_context,
      warning
   return v_clob;
end blob2clob;
/Difference here is that Richard uses default charset - we have need for AL32UTF8 charset. You should use whatever is relevant for your case.
The use of either Richards function or the above is simple for your insert as select:
insert into tab_c (clob_col)
select blob_to_clob(blob_col) from tab_b
