CLOB to FILE (or BLOB to file)
How to save into a server-side file a CLOB data ?
Edo.
Possibly read in the text file with FileReader line by line, into one string, then insert with an update too database. Like this....
DataInputStream dis = null;
FileInputStream fis = new FileInputStream("whatEver.xml");
BufferedInputStream bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
String myXMl = "":
while ( (line=dis.readLine()) != null )
myXML += line;
//then add you database query to update into the field that is a blob;
But watch out for XMl with dodgey chars like squars, they can effect the performance.
Insuch a case you would read in char by char and ignor these chracters.
good luck hope that helped.

How can I open different binary files from BLOB column ?
If we store some type of binary file (XLS, DOC, PDF, EML and so on, not only pictures) in BLOB column how can I show the different contents? We use designer and forms 9i with PL/SQL.
How can I copy the files from BLOB to file in a directory or how can I pass BLOB's content to the proper application directly to open it?The mime type is just a string as explained above (e.g. application/pdf...). There are lot of samples here and on metalink.
E.g. add a column mime_type varchar(30) to your blob table. Create a procedure similar to the following:
PROCEDURE getblob
(P_FILE IN VARCHAR2
IS
vblob blob;
vmime_type myblobs.mime_type%type;
length number;
begin
select document, mime_type into vblob,vmime_type from myblobs where docname = p_file;
length := dbms_lob.getlength(vblob);
if length = 0 or vblob is null then
htp.p('Document not available yet.');
else
owa_util.mime_header(vmime_type);
htp.p('Content-Length: ' || dbms_lob.getlength(vblob));
owa_util.http_header_close;
wpg_docload.download_file(vblob);
end if;
exception
when others then
htp.p(sqlerrm);
END;
Create a DAD on your application server (refer to documentation on how to create a DAD).
Display the blob from forms (e.g. on a when-button-pressed trigger):
web.show_document('http://myserver:port/DAD/getblob?p_file=myfilename','_blank');
For storing blobs in a directory on your db server take a look at the dbms_lob package.
For storing blobs in a directory on your app server take a look at WebUtil available on OTN.

Parsing BLOB (CSV file with special characters) into table
Hello everyone,
In my application, user uploads a CSV file (it is stored as BLOB), which is later read and parsed into table. The parsing engine is shown bellow...
The problem is, that it won't read national characters as Ö, Ü etc., they simply dissapear.
Is there any CSV parser that supports national characters? Or, said in other words - is it possible to read BLOB by characters (where characters can be Ö, Ü etc.)?
Regards,
Adam

Hi everybody.
I'm newbie with Java. How to put file to BLOB field?I have read section "Populating a BLOB or CLOB Column in a New Table" from Oracle9i JDBC Developer's Guide and Reference. But i did'n found any answer how to put external file to BLOB field into the table.
What is wrong in my code?

How to upload a image or flash file as blob object in a table.
How to upload a image or flash file as blob object in a table.
What are all the possible ways we can do it.Searching the forum (or google) would be my first choice, as this question pops up every now and then.
Next without knowledge of your environment (jdev version and technology stack) it's hard to give a profound answer.
All I can say is that it's possible.

How can i put a file into blob(using sun.jdbc.odbc.JdbcOdbcDriver)
Hi
i tried to put a file into blob , but got a problem.....
My environment:windows 2000pro,JBuilder 5.0 enterprise,oracle 8.1.6,(not install oracle jdbc driver )
a part of program(my program is very uglily,if anyone want,later i paste it ba....~_~)
//Statement stmt2=null;
//Resultset rs2;
//opa1 is the blob data
void saveBlobTableToDisk(Connection con) {
try {
stmt2=con.createStatement();
sqlStr2="SELECT * FROM emp3 where id=1004";
rs2=stmt2.executeQuery(sqlStr2);
while (rs2.next()) {
Blob aBlob=rs2.getBlob("opa1");
i got the exception :
" null

and the windows pop up a messagebox said that(about) my memory "0x09af007f" could not read, error in javaw.exe .
Later i used (ResultSet)getBinaryStream() to solve it. but getBinaryStream() only return a InputStream,so that i can make blob to a file,but i can't make a file to blob using jdbc.....
I am very stupid that installing sun java, oracle jdbc driver etc....(because i must set a lot of thing such as classpath,java_home etc), Can i only use JBuilder to do that ?
Or i must install oracle jdbc driver ?
Thanks.My guess here is that Sun's JDBC-ODBC bridge doesn't handle the BLOB datatype. Most ODBC drivers don't support that datatype, so I wouldn't expect the bridge to.
Is there a reason that you can't use the Oracle driver?

I have being storing PDF files using Blob, but it is getting very time consuming to access these files again.
Is there a better way of doing it? Is there a right way of doing it? I do not need to search inside the PDF, but I do need to access them either inside the Database or outside.
Thank You for nay helpI have a need to store PDF files that are documents that will complement process that my systems creates. And I need that those PDF files be accessible from inside my system, I do not need to search insede them because they will be stored by subject inside another subject, therefore whoever need the files will know were to find it, but to store and to access it is taking longer and longer as more files are added to the first thead.

Getting a PDF file in BLOB variable
Hi Forum,
I want to get a PDF file in BLOB variable from DB server.
Further I will pass that variable to a procedure; in that procedure that variable will be inserted into a table.
I have called procedure (inserting BLOB into a table) is ready.
Can someone advice?
thanks,

Someone used upload files into blob in JDeveloper 10.1.3.2 ?
Someone used upload files into blob in JDeveloper 10.1.3.2 ?
I used Steve Muech example 85, but after downloading , downloaded files doesn't work ?
I prepared test case http://www.sttb.pl/jakub/UploadAndDownloadBlob.zip - meybe someone resolve it.
Regards
KubaHi,
There is no problem with download in above example. I have used Steve's example to upload, and solution delivered by Ric Smith on his blog to download files. I think there is something wrong with Steve's uploading solution. When I used Ric solution (he sent me by email complete JDeveloper project) to upload and download everyting works correct. I created last Friday SR on Metalink to review it and it's still in progress. My advice is:
1) Look onto Ric Smith blog:
http://thepeninsulasedge.com/blog/2006/08/17/reading-and-writing-blobdomains-to-and-from-an-adf-uploadfile/
and
http://thepeninsulasedge.com/blog/2006/11/06/adf-faces-and-adf-bc-fileupload-and-blobs-continued/
2) Ask him to send JDeveloper project or update email to your profile - I'll send you directly this project that I retrieved from Ric Smith

Load blob to file. error: file write error
Hi,
I used procedure witch load blob to file. It's working at Oracle 10g, but its does't work on oracle 11g. Why?
create or replace PROCEDURE load_blob_to_bfile (p_file_id IN VARCHAR2, p_directory IN VARCHAR2, p_ident in varchar2 default NULL)
IS
v_blob BLOB;
v_start NUMBER := 1;
v_bytelen NUMBER := 2000;
v_len NUMBER;
v_raw RAW (2000);
v_x NUMBER;
v_output UTL_FILE.file_type;
v_file_name VARCHAR2 (200);
BEGIN
-- get length of blob
SELECT DBMS_LOB.getlength (blob_content), filename
INTO v_len, v_file_name
FROM wwv_flow_files
WHERE filename = p_file_id;
-- define output directory
v_output := UTL_FILE.fopen (p_directory, p_ident||'_'||v_file_name, 'wb', 32760);
-- save blob length
v_x := v_len;
-- select blob into variable
SELECT blob_content
INTO v_blob
FROM wwv_flow_files
WHERE filename = p_file_id;
v_start := 1;
WHILE v_start < v_len AND v_bytelen > 0
LOOP
DBMS_LOB.READ (v_blob, v_bytelen, v_start, v_raw);
UTL_FILE.put_raw (v_output, v_raw);
UTL_FILE.fflush (v_output);
/* Text only could be: UTL_RAW.cast_to_varchar2 (v_raw);*/
-- set the start position for the next cut
v_start := v_start + v_bytelen;
-- set the end position if less than 32000 bytes
v_x := v_x - v_bytelen;
IF v_x < 2000
THEN
v_bytelen := v_x;
END IF;
END LOOP;
UTL_FILE.fclose (v_output);
END;
directories is creaited and granted for read and write. It looks like file is created, but application rise the write file error, and files in directory is emty.
TomasBSo, I'm copying the file in a temp. BLOB with this function:
FUNCTION get_remote_binary_data (p_conn IN OUT NOCOPY UTL_TCP.connection,
p_file IN VARCHAR2)
RETURN BLOB IS
l_conn UTL_TCP.connection;
l_amount PLS_INTEGER;
l_buffer RAW(32767);
l_data BLOB;
BEGIN
DBMS_LOB.createtemporary (lob_loc => l_data,
CACHE => TRUE,
dur => DBMS_LOB.CALL);
l_conn := get_passive(p_conn); //get a passive connection
send_command(p_conn, 'RETR ' || p_file, TRUE); //send Retrieve command to server
BEGIN
LOOP
l_amount := UTL_TCP.read_raw (l_conn, l_buffer, 32767);
DBMS_LOB.writeappend(l_data, l_amount, l_buffer);
END LOOP;
EXCEPTION
WHEN UTL_TCP.END_OF_INPUT THEN
NULL;
WHEN OTHERS THEN
NULL;
END;
UTL_TCP.close_connection(l_conn);
get_reply(p_conn);
RETURN l_data;
END;
Then I'm writing it into a local file:
PROCEDURE put_local_binary_data (p_data IN BLOB,
p_dir IN VARCHAR2,
p_file IN VARCHAR2) IS
l_out_file UTL_FILE.FILE_TYPE;
l_buffer RAW(32767);
l_amount BINARY_INTEGER;
l_pos INTEGER := 1;
l_blob_len INTEGER;
BEGIN
l_blob_len := DBMS_LOB.getlength(p_data);
l_amount := DBMS_LOB.GETCHUNKSIZE(p_data);
IF (l_amount >= 32767) THEN
l_amount := 32767;
END IF;
l_out_file := UTL_FILE.FOPEN(p_dir, p_file, 'w', 32767);
WHILE l_pos < l_blob_len LOOP
DBMS_LOB.READ (p_data, l_amount, l_pos, l_buffer);
UTL_FILE.put_raw(l_out_file, l_buffer, FALSE);
l_pos := l_pos + l_amount;
END LOOP;
UTL_FILE.FCLOSE(l_out_file);
EXCEPTION
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(l_out_file) THEN
UTL_FILE.FCLOSE(l_out_file);
END IF;
RAISE;
END;
I've checked the blob before I'we wrote it ito the file (UTL_FILE.put_raw(l_out_file, l_buffer, FALSE)), and it contains no carriage-return.
