Insert BLOB problem

Hi:
I'm using oracle 8.1.6 on SunOS 5.7.
I tried to insert a MS Word file into a blob column, but failed.
Following are what I did:
create table test
(id number primary key,
text blob
insert into test (id,text) values (1,empty_blob());
create directory filedir as '/home/mydir';
Declare
lobd BLOB;
fils BFILE;
BEGIN
fils := BFILENAME('filedir','test.doc');
SELECT text INTO lobd FROM test WHERE id = 1 FOR UPDATE;
dbms_lob.fileopen(fils, dbms_lob.file_readonly);
dbms_lob.loadfromfile(lobd, fils, dbms_lob.getlength(fils));
COMMIT;
dbms_lob.fileclose(fils);
END;
I got error message:
DECLARE
ERROR at line 1:
ORA-22285: non-existent directory or file for FILEOPEN operation
ORA-06512: at "SYS.DBMS_LOB", line 475
ORA-06512: at line 7
The file test.doc is at that directory /home/mydir. I tried to replace
'filedir' with '/home/mydir' in the line
fils := BFILENAME('filedir','test.doc');
but still no success.
Could anyone give me some advices?
Thanks,
George

Hi Omar,
Could anyone tell me how to insert a file (say a word doc., or a PDF or a text document) into a column of a table of type BFILE or BLOB. I know that it is possible to map to the physical file on the filesystem thru logical directory creation. But, would like to know how to insert a file into the column and use it later for retireval, string searching, etc. from the queries. Is it thru SQL*Loader? Could u explain me(with example, if poss.) how to do this with the loader utility?
Pls guide me thru this.
Thanks!
Regards,
Sanjay

RegisterOutParameter - setBinaryStream - Problems inserting Blob - setRAW

As posted in metalink (was: "Problems inserting BLOB/InputStream with ojdbc14.jar for 10g - Data size bigger than max size for this type"):
Using setBinaryStream for large Blobs works as long as I don't register outParameters.
Query that works: "INSERT INTO blobtest (attachment_id,name,data) VALUES(blobtest_SEQ.nextval,?,?)";
Query that fails = "BEGIN INSERT INTO blobtest (attachment_id,name,data) VALUES( blobtest_SEQ.nextval,?,?) RETURN attachment_id INTO ? ; END;"
The necessary tables were created by hand:
CREATE TABLE blobtest ( NAME CHAR(255), data BLOB, attachment_id NUMBER(38))
And
CREATE SEQUENCE TBL_ATTACHMENT_SEQ
The output was: <<user: SEE
pw: QD
instantiating oracle driver
query: INSERT INTO blobtest (attachment_id,name,data) VALUES(TBL_ATTACHMENT_SEQ.nextval,?,?)
uploaded no Return Parameter blob of size: 256809
query: BEGIN INSERT INTO blobtest (attachment_id,name,data) VALUES(TBL_ATTACHMENT_SEQ.nextval,?,?) RETURN attachment_id INTO ? ; END;

Apparently, this is partially known - with a different stacktrace though:
<<From: Oracle, Anupama Srinivasan 25-Apr-05 07:15
Can you please check on Bug:4083226?
Using the RETURNING Clause is not supported with JDBC. You could embed the statement in PL/SQL Block as in Metalink Note 124268.1 - JDBC Support for DML Returning Clause.
The Enhancement Request filed on this issue is being considered for Release 10.2
>>
And my answer to it.
Using the RETURNING Clause is not supported with JDBC.This is strange, with just "emptyblob()", it DOES work.
I guess, our work-around that hopefully is more portable than embedding a "PL/SQL Block" will be to
1) create the record with an empty blob,
2) update the blob in a second statement (now, a RETURNING statement is no longer needed)

Blob Problem

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.
The error message i am getting:
java.sql.exe:ORA-06550 line col22
PLS 00302: Component GETCHUNKSIZE must be declared
ORA-06550 line1 col 7
pl/sql statement ignoured

You are probably better off using BLOBs rather than BFILEs. The main reason for this is that with BLOBs data integrity between file and its meta data in the database are managed and protected by the RDBMS. BFILEs are useful for legacy systems where the files already exist in some form of meaningful and managed structure that needs to be preserved.
There is a down side to BLOBs and that is performance - BLOBs are relatively slow to load into the database. However, its not too bad and the performance of extracting BLOBs out from the database is quite reasonable the bottleneck is more likely to be your LAN.
In order to use BLOBs it is important to have the right class libraries involved. For BLOBs you must use the classes12.zip (supplied with the database) for JDBC2 support and furthermore put this class high up the list of class libraries if you do not you may find that your code compiles but raises a runtime exception about invalid data types; this is because the wrong definition of the Blob class is being picked up.
Assuming that you are using BLOBs then the following describes the techniques for storing files as BLOBs in an Oracle database.
LOADING BLOBS
Assuming that you have a table with a BLOB column in it then to load a BLOB you must first create the record containing the BLOB by inserting a row into your table with the value of the BLOB column set to EMPTY_BLOB( ) (PL/SQL built in):
INSERT INTO tablex( col1, col2, colBLOB )
VALUES( val1, val2, EMPTY_BLOB() )
Then you must row lock this record and obtain the LOB locator for the BLOB just created:
stmt = connection.createStatement();
query = "SELECT colBLOB FROM tablex WHERE ... FOR UPDATE OF colBLOB";
ResultSet lockLOBSet = stmt.executeQuery(query);
At this point you should be able to use lockLOBSet.getBlob(1) to create a binary stream to load the BLOB directly into the database. Under Java Developer 2 I could never get this to work and havent tried since with Java Developer 3. Instead I used the PL/SQL DBMS_LOB package and did it using JDBC; this assumes that the file has been loaded into a buffer binaryFile and note that the maximum chunk size that dbms_lob.write can be called with is 32K:
blobLoc = lockLOBSet.getBlob(1);
while(amountWritten < fileSize)
if ((amountWritten + writeAmount) <= fileSize)
writeAmount = 32000;
else
writeAmount = fileSize - amountWritten;
System.arraycopy(binaryFile, amountWritten, buffer, 0, writeAmount);
CallableStatement cstmt =
connection.prepareCall("{call dbms_lob.write(?, ?, ?, ?)}");
cstmt.setBlob(1, blobLoc);
cstmt.setLong(2, writeAmount);
cstmt.setLong(3, amountWritten + 1);
cstmt.setBytes(4, buffer);
cstmt.execute();
cstmt.close();
amountWritten = amountWritten + writeAmount;
EXTRACTING BLOBS
Binary streams do work when it comes to reading BLOBs out of the database so things are a whole lot simpler probably worth trying it with loading BLOBs now as well.
ResultSet queryLOBSet = statement.executeQuery(query);
if(queryLOBSet.next())
lobSize = queryLOBSet.getInt(1);
blobLoc = queryLOBSet.getBlob(2);
BufferedInputStream bi;
blobBuffer = new byte[lobSize];
bi = new BufferedInputStream(blobLoc.getBinaryStream());
amountRead = bi.read(blobBuffer);
bi.close();

Please HELP!!! I try to insert BLOB to Oracle

Please help, I try to insert BLOB to Oracle.
Here is my sample code. Basically what i tried to do is to to try to insert an image file to Oracle.
But it did not work. If you have a sample code that works, please give me.
Thanks,

rset.next();
BLOB bdata = rset.getBLOB("test.jpg");
os = bdata.getBinaryOutputStream();
os.write(bdata);
os.flush();
os.close();
dbCon.commit();
dbCon.close();
catch (Exception ex)
ex.printStackTrace();

Well, the obvious problem is that your "getBLOB" call ought to access the field by the field name "FOTO" not by a file name. Then you need to open an FileInputStream for the image before copying it to the blob's output stream.
In my opinion BLOB and CLOB handling is jdbc is a confusing mess.

Inserting blob data into database

Hello everybody,
I need insert blob data into database. that data i need to get from form
can i use request.getParameter(""); for getting that file.
Plz help how to get data from form to servlet and through callablestatement i need to insert into database.
regards,
Anil

Hi,
1) first create a form with file element
first.jsp
<form action="GetData" enctype="multipart/form-data" method="post">
<input type="file" name="datafile" size="40">
<input type="submit" value="Send">
<input type="reset" name="Reset" value="Cancel">
</form>
GetData.java
// servlet file
public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
res.setContentType("text/html");
PrintWriter out = response.getWriter();
try {
System.setProperty( "jdbc.drivers", "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
con = DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=JAVATEAM;SelectMethod=cursor;User=sa;Password=urpassword" );
PreparedStatement pst = con.prepareStatement("insert into uploads(binaryfile) values(?)");
FileInputStream fis=new FileInputStream(request.getParameter ( "datafile" ) );
byte[] b= new byte[fis.available()+1];
fis.read(b);
pst.setBytes(1,b);
pst.executeUpdate();
pst.close();
con.close();
catch(SQLException e)
out.println ( e);
catch (ClassNotFoundException e)
out.println( e );
}Here in doPost(), i create preparedstatement,
now you to create one procedure for insert
and by using callable statement you just call that procedure and pass this byte b as arguments,
now its in your hands
my idea is over.

SQLite3 and BlobsI am having trouble learning how insert blobs into SQLite

I am having trouble learning how insert blobs into SQLite for the iphone. Is there a way to insert a blob into sqlite3 from the command line? I know it was possible with sql using
INSERT INTO temponly(name , pic) values( 'velan',
load_file('e:/mysql/images/Click.gif')) ;
but I don't think load_file is supported on sqlite.
Also, I need to insert the blobs from my iphone app. I saw a C program called eatblob.c which goes through the following just to INSERT a blob into sqlite
1. read the jpeg image file into memory , doing appropriate malloc based on size
2. prepare an sqlite statement with ? values
3. bind the malloc'd memory to the ?
4. execute an sqlite step
etc. etc. etc....
This is quite a bit of work just to do an INSERT ???
The reason I'm doing this is my iphone app has a lot of tiny (20x20) images that get downloaded to the phone periodically from the server. Plus, there are a number of images that come loaded with the application. I was going to save all of these in SQLite. So, I need the command line tool to load up the initial images that come with the app, then I need code to download the images from the server and load them into the database. Of course, reading them out is necessary!
Please help if you can!? Its late..and I'm blurry eyed from googling SQLIte3 blobs...

Thank you for your quick reply Liam! You know, I checked the web forms list when I got that error message and the form isn't there. I was having trouble the other day when another of my forms kept getting deleted.
Sorry if this is a stupid question (I'm a BC newbie) but I want to be sure so I can get this project finished... The proper workflow would be to create this form myself in Web Forms then insert it into the Registration - Buy template using the modules toolbox?
Thanks to you I may get this done on time still... if my PayPal set up works

Single record insert performance problems

Hi,
we have on production environment a Java based application that makes aprox 40.000 single record Inserts per hour into a table.
We ha traced the performance of this Insert and the medium time is 3ms, that is ok. Our Java architecture is based in Websphere Application Server and we access to Oracle 10g through a WAS datasource.
But we have detected that 3 or 4 times a day, during aprox 30 seconds, the Java service is not able to make any insertion in that table. And suddenly it makes all the "queued inserts" in only 1 second. That "pause" in the insertion cause problems of navigation because is the top layer there is a web application.
We are sure that is not a problem with the WAS or the Java code. We are sure that is a problem with the Oracle configuration, or some tunning action for this kind of applications that we don´t know. We first thought it could be a problem with a sequence field in the table. Also, a problem when occurs the change of the redo log. But we've checked it with our DBA and this is not the problem.
Has anybody any idea of what could be the origin of this extrange behaviour?
Thanks a lot in advance.
Jose.

There are a couple of things you'd need to look at to diagnose this - As Joe says it's not really a JDBC issue from what we know.
I've seen issues with Oracle's automatic SGA resizing causing sporadic latency in OLTP systems. Another suspect would be log file sync wait events, which are associated with commits. Don't discount the impact of well meaning people using tools like TOAD to query the DB - they can sometimes cause more harm than good.
Right now I'd suggest you run AWR at 10 minute intervals and compare reports from when you had your problem with a time when you didn't.

Inserting BLOBs Programmatically

Is it possible to insert BLOBs programmatically?
http://java.sun.com/docs/books/tutorial/jdbc/jdbc2dot0/inserting.html
has details on this, but it appears to be at odds with the "empty_blob()" mechanism used by oracle, which requires an explicit insert statement.
Thanks,
Sanjay

Although jdbc can't immediately see how the Blob/Clob needs to be implemented the database implementors should. The sequence should be as you suggest: create a new blob, write the data to it then store the OID in the database with a PreparedStatement.
Because the Blob needs to be database implementation specific new Blobs should be created from the Connection object. In the typical case writing to the Blob should write straight to the database. Copying block values from one record to another should just involve copying the OID.
As I read the Blob class description it should mean that the actual data isn't moved to or from the client unless you open a stream on it.
Looking at the postgres implementation source it's pretty crude, in fact whereas retrieving a blob works as I suggested; no reads from the database until you open the stream, when you write the blob back to the database it's creating a new OID every time. I'd assumed it would retrieve the OID from the Blob you passed to PreparedStatment.setBlob actually it creates a new OID and copies the data byte by byte (icky).
Looks, in fact, as if I can create a fake Blob with nothing but a getBinaryStream method.
setBinaryStream/setAsciiStream doesn't work properly because it seems to decide whether the field is a blob purely based on the implementation version of postgres, without regard for the field type. (I suppose you can't judge the field type in a PreparedStatement).

Problem inserting Blob through Oracle 9iAs

Hai Everybody,
I got a unique problem , i am trying to insert a blob object to the blob column. This is working fine when i am using JDeveloper 9.0.3 , but when i am using the same on 9iAS , the data is not evening inserting to the database. Please can any body help me how to solve this problem.
This is the code used to insert into the database.
if (resSet.next()) {
oracle.sql.BLOB bCol = ((OracleResultSet)resSet).getBLOB(1);
blobOutputStream = bCol.getBinaryOutputStream();
byte[] bBuffer = new byte[bCol.getBufferSize()];
int intBytesRead = 0;
ByteArrayInputStream fis = new ByteArrayInputStream(byteValues);
ErrorLog.log(" before the while loop ");
while ((intBytesRead = fis.read(bBuffer)) != -1) {
blobOutputStream.write(bBuffer,0,intBytesRead);
blobOutputStream.close();
// i am commiting the connection here
conn.commit();
conn.setAutoCommit(true);

Blob problem (Image storing or Currupted )

AOA!
I am working as a developer in a companey. we made a database for HRMS. In this database there is a table EMPLOYEE with a column PICTURE of type BLOB. We were using oracle 8i initially but when we migrate to oracle 9i, we are facing a problem in image storing. The situation is, database showing ur previously stored images (those have stored in oracle 8i) but when we save a new image in that table or any other table it seams to be saved but cannot retrived. I mean when we issue a query
SELECT EMP_ID FROM EMPLOYEE WHERE PICTURE IS NOT NULL;
It shows the new inserted records too (thats shows us that picture has been inserted) but when we issue query from a forms6i application it didnt show any image. In case of report, when we try to query a record which newly inserted with image, it says some thing like REPORT IS UNABLE TO SHOW IMAGE FORMATE etc.
The situation is for all table and all schema which is indicating us may be it is some thing due to oracle 9i headen technique or due to miss managment by us. we dont have DBA in our companey.
Please help us in this regard. We will be thankfull to you.

I think that both your SQL is wrong and your intended use is wrong. According to the SQL reference, the following seems to be a simplified definition that seems to match what you're trying to do. UPDATE <table> SET <column> = <expr>. So PROPERTIES should be a <table> of some kind and X should be a <column> of that table. This changes your PreparedStatement to *"UPDATE PROPERTIES SET X = ? WHERE NAME = ?"* Then you can do ps.setBlob(1, b) and ps.setString(2, ...). Because your statement is DML you must do ps.executeUpdate(). So your code might look something like this.
Blob b = ...;
String x = ...;
ps = c.prepareStatement("UPDATE PROPERTIES SET X = ? WHERE NAME = ?");
ps.setBlob(1, b);
ps.setString(2, x);
int i = ps.executeUpdate();
The executeUpdate() returns the row count (i.e. number of rows) of your DML statement. Try that and see if it helps.
