BLOB, BFILE problems
We have tried different methods to get these data types to work in a PO8 environment. If we use the Oracle Navigator we can store and read blob data. When we try the same using JDBC 2.0 driver we can not get even the insert to work correctly. Has anyone ever been successful in getting it work. The samples of codes in many books don't seem to have been tested either because they don't work either!
For example, using the BFILE option (example given by Steve Bobowski)gave us a FILEOPEN exception ORA error 22285 (No directory exists or cannot open file). The directory and the file does exist and the user has the required permissions!
Any help?
Chapter 7 in the Oracle Call Interface Programmer's Guide discusses [LOB and BFILE operations|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14250/oci07lob.htm#g452677]. Given that you are posting here, I assume you are interested in using the OCI interface and that you are familiar with the basics of OCI programming. If not, you'll want to read the other chapters in the OCI Programmer's Guide.

hello gurus
i would like to know how is possible within Oracle Forms (i am still using 6i) to retrieve a MS office document stored in an oracle DB and showing it using ole2 automation.
I miss just the step of retrieving from DB and loading it into memory or somewhere on the client filesystem, so let it be opened with the right MS office application (chosen with ole2)
My actual idea is to create a block based on the table that stores the blob (bfile) column, but i don't know how to store the blob (bfile) object in the forms application.. there is a particular object to use? or i must just load the key (or rowid) and then requering the table using it? and after loading the blob (bfile) from table, how can i convert it to be usable for ole2?
thanks in advance!

Hello,
I have the following problem:
1. I can upload PDF files into BFILE(s) - in the DATA_PUMP_DIR (dba_directories table)
2. The uploaded file can be opened/viewed with Adobe Acrobat Reader.
3. I use a stored procedure do download the PDF files from my browser.
4. the download works ok but the file can no longer be opened/viewed using Adobe Acrobat Reader.
5. I did a hex compare of 2 pdf files (the uploaded file and the downloaded file) and I think it is a CR vs CRLF conversion problem.
I am using Oracle 10g XE on a Linux box and Windows as a client. The upload/download is part of a APEX application.
This is the code used to download the BFILE:
Note: v_mime is set to 'application/pdf'.
x_bfile := BFILENAME ('DATA_PUMP_DIR', p_file);
DBMS_LOB.fileopen (x_bfile, DBMS_LOB.LOB_READONLY);
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||substr(v_file_name,instr(v_file_name,'/')+1)|| '"');
-- close the headers
owa_util.http_header_close;
BEGIN
LOOP
DBMS_LOB.READ (x_bfile,
n_size,
n_pos,
x_buffer);
HTP.prn (UTL_RAW.cast_to_varchar2 (x_buffer));
-- increment number of bytes read
n_pos := n_pos + n_size;
END LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
END;Any suggestions?
Thanks,
Catalin Florean.You could try using wpg_docload.download_file instead of htp.prn.
Here is part of the procedure I use for downloading MP3 files from BFILES:
owa_util.http_header_close;
dbms_lob.createTemporary(TBlob, true);
dbms_lob.open(Lob_loc, dbms_lob.file_readonly);
dbms_lob.loadfromfile( TBlob, Lob_loc, dbms_lob.getlength(Lob_loc) );
dbms_lob.fileclose(Lob_loc);
-- download the BLOB
wpg_docload.download_file( TBlob );
dbms_lob.freeTemporary( TBlob );You would replace my Lob_loc variable with your x_bfile. -
Hello,
The problem that i have is that i want to insert a file residing in the network into the oracle database into a blob field and again read it from the database and show it ie either insert it into a file directly and then open it using the correct editor or open it directly. I am using java along with it but i am basically stuck on the database side.
I am sending the code which i have written till date
i basically need to know
1)the syntax i am using to interact with the database is right ie where is the error in the code
2)provided that is ok whether my overall code is on the right track.
After line control 10
The error message i am getting:
java.sql.SQL Exception:ORA-22288:file operation fileopen failed
LFI:00108:open expect the file[map][gif] to exist
ORA-0615:at"SYS.DBMS_LOB",line 370

nullHi
Have you found a workaround for this problem? im having a similiar problem and am interested in its solution..... -
Hi,
I have some problems with blob mapping.
I map a Serializable field in a BLOB column (in MySQL 4.1 w/ latest Kodo
version) using following metadata:
<field name="metadata" persistence-modifier="persistent">
<extension vendor-name="kodo" key="type" value="Object"/>
<!-- extension vendor-name="kodo" key="jdbc-size" value="-1"/ -->
</field>
<field name="metadata">
<jdbc-field-map type="blob" column="METADATA"/>
</field>
Making the object persistent works well. The generated SQL is
INSERT INTO ATTRIBUTE_TYPE (METADATA, NAME, POID)
VALUES (?, ?, ?)
[params=(InputStream) java.io.ByteArrayInputStream@1c9b9ca, (String)
IntegerNew3, (long) 250] [reused=0]
Problems occur when I try to load the object. I get a ClassCastException
(see below). For information:
- I have saved the blob to my hard disk, and read it using
ObjectInputStream, and it works fine. So, the object is correctly stored.
- I have set the field in my Java class to java.lang.Object (instead of
my class implementing Serializable), and then it works fine too.

Hi,
This is a known issue with MySQL, and Kodo 3.3.3 has a workaround for it
-- set the DBDictionary DriverDeserializesBlobs property to false:

-PatrickDon't take it bad, but then why don't you put it in the MySQL known issues
in the documentation. It is a pity to waste hours on a known problem.

Persist document in BLOB column problem
Hi all,
I'm having problem with persisting document in BLOB column.
Using debuger I checked that document.doc contains correctly uploaded file before persist. There are other attributes of document and they are persisted correctly, but when I check blob size in database it size is 1byte which is incorrect.
After I persist second file, first one get his correct size value, and size of second one is 1byte.
If I stop weblogic server, second value will never be populated. If I only restart application without restarting server, and then upload third document, size of second one will be corrected.
Oracle JDeveloper 11g R1 11.1.1.2.0

Using ADF 11g RC & EJB
I set id manually.

Hello again.
I have the following code:
java.sql.ResultSet resultSetForUpdate = stat.executeQuery("select picture from some_table where some_id=" + someId + " for update");
java.sql.Blob blob = resultSetForUpdate.getBlob(1);
// here is some code that types the class of the blob
logger.info("blob class is: "+blob.getClass());
now the problem is that the class returned with blob.getClass is different on 2 portals... on 1 portal I get oracle.sql.BLOB (this is the expected result) but on the other I get com.inqmy.services.dbpool.remote.RemoteBlobImpl
does anyone have any idea why this is happening and how can I do so that I always get the oracle.sql.BLOB class?
more information: both portal installations are ep6 sp2 with (I think) identical patch levels (35 if I remember correctly). the database they access is the same one. the dbpool definitions (in visual administrator) look similar.
thanks in advance.
silviu.Thanks for taking the time to look at this.
No, it is the same driver on both servers. The driver is the oracle driver oracle.jdbc.OracleDriver provided by Oracle themselves.
This is not it...
Could there be some path problem? The server on which it works fine is a windows machine, whereas the server where it doesnt work is a solaris machine, I think (not windows for sure).

I have the problem with file bigger than 32 ; i printed the value of sqlerrm and sqlcode
the results ar sqlerrm = User-defined exception
sqlcode = 1
Ony body can help me
Thanks
MarcHi
Call the function without exepction handling and post the error message and the number of the line where the error occures.

hi all,
im facing an stylist problem when inserting blob into oracle dbms. im trying in a very simple way like this :
stmt.executeUpdate("insert into picture values('sample1.gif',empty_blob())");
ResultSet rs= stmt.executeQuery("select * from picture where name='sample1.gif' for update");
rs.next();
oracle.sql.BLOB blob=(oracle.sql.BLOB)rs.getBlob(2);
FileInputStream in= new FileInputStream(filename);
OutputStream os=blob.getBinaryOutputStream();
int data;
while((data=in.read())!=-1){
os.write(data);
in.close();
os.close();
this code is ok but i have an allergy about standerizing my coding so im trying to use the following code :
stmt.executeUpdate("insert into picture values('sample1.gif',empty_blob())");
ResultSet rs= stmt.executeQuery("select * from picture where name='sample1.gif' for update");
rs.next();
java.sql.Blob blob=rs.getBlob(2);
FileInputStream in= new FileInputStream(filename);
OutputStream os=blob.setBinaryStream(1);
int data;
while((data=in.read())!=-1){
os.write(data);
in.close();
os.close();
but the problem is setBinaryStream(int pos) is not implemented by oracle.sql.BLOB class. my oracle version is 9.0.1.0.1. when i run it,it shows an exception like abtract method error. is there any way not to use the oracle.sql.BLOB for inserting blob into oracle database ?I can't give a definitive answer but I've observed the same problem.
The ability to get an outputstream to a Clob was only introduced in JDBC 3.0.
Chapter 5 of Oracle's JDBC Developer's Guide and Reference http://download-west.oracle.com/docs/cd/B10501_01/java.920/a96654/jdbc30ov.htm#1004903 mentions that only some JDBC 3.0 features are implemented; none of the mentioned features include the API calls for streaming to a Clob.

Help abt store and delete images as blob & bfile using Visual C++
Hi
Does anyone knows if there is code for visual c++
to store and delete images as blob or bfile?
thanxThe documentation states there are examples in the oracle database distribution: <ORACLE_HOME>/rdbms/demo/cdemolb.c <ORACLE_HOME>/rdbms/demo/cdemolb2.c <ORACLE_HOME>/rdbms/demo/cdemolbs.c
These examples are in c, but can be used in c++

hello Gurus,
I want to know these two things
٭ How to use BLOB data type?
٭ How to use BFILE data type?
Regards
Santosh KumarApart from what Raford mentioned, you should also keep in mind about the security aspect of it.
Documents stored in db are more secured or can be made more secured.
When you use bfiles, they are stored in OS and thus can be deleted intentionally or by mistake.
Performance wise, they donot make much difference even though bfile have an overhead of going to file system to fetch the fiiles/information. -
We are inserting a BLOB in our table. If the size of BLOB is greater than 5KB, it's not being inserted. Smaller BLOBs are being entered successfully. Is ther some default parameter which need to be set.
AFAIK there is no such initialization parameter.
How do you insert BLOB ? Which is the host language ?
Which use case described in http://download-uk.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl10pst.htm#125074 is the closest to the one you are using ? -

Hello,
I am using 8.1.7 on Solaris. I store a Word document in a blob column and index it without errors. However when I try to select from this column using "select...contains" it always results in zero rows being returned. Changing the filter to NULL_filter using the 'parameters' clause in the create index statement works, but the DR$ table contains a lot of binary chars as well as text as a result.
If anyone could help I'd be most grateful.
Thanks,
HNThank you for your reply. Here is the script.
drop table ImageTable;
create table ImageTable
(myCount number, myImage blob);
alter table ImageTable add constraint pk_imageTable primary key (myCount);
insert into ImageTable values(1, empty_blob());
commit;
create index idx_imageTable on imageTable(myImage) indextype is ctxsys.context;
-- create index idx_imageTable on imageTable(myImage) indextype is ctxsys.contex
t parameters('filter ctxsys.null_filter');
The following lines insert a Word95 doc which contains only one line:
"This is a test document."
host javac SearchW2K.java
host java SearchW2K
alter index idx_imageTable rebuild online parameters('sync');
select myCount from imageTable where contains(myImage,'test') > 0;
