SetBinaryStream

Hello,
I'm having trouble with the java.sql.PreparedStatement.setBinaryStream() method with oracle 10g. While it used to work well before in a PostgreSQL database, it does not save data if its size is more than 2k. I'm using the latest jdbc thin driver for 10g. The frustrating part is that there are no error messages returned and all the other non-blob column updates are saved except for the blob column.

I got the latest drivers for Oracle 10g and they seem to have solved the problem. I was however, working with a 10g driver and 10g database, so I'm not sure if this will work for earlier versions of Oracle DB. At first it didnt work but that was because I only copied the ojdbc14.jar into my servlet's WEB-INF/lib directory (although it works for other JDBC drivers) instead of specifying it as part of the classpath.

AbstractMethodError while calling PreparedStatement.setBinaryStream()

I am getting AbstractMethodError while calling PreparedStatement.setBinaryStream(int, InputStream) for a BLOB column
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit
JDBC Driver ojdbc6.jar (downloaded from oracle website corresponding to 11.2.0.2 version)
JDK 6
I understand this error is due to my code calling abstract method which is not available in JDBC 3.x and it requires JDBC 4.0
But I am not able to find any traces of usage of earlier version of driver.
Debugging steps performed with results are as below
1) I enabled -verbose:class VM argument that outputs all the classes loaded along with jar from which it loads. Everywhere i see ojdbc6.jar (No reference to older or any other jdbc driver jar file)
2) Below is code segment and its output
Connection con = getConnection(); // get connection
DatabaseMetaData d= con.getMetaData();
d.getDatabaseProductName(); // output: Oracle
d.getDatabaseProductVersion(); // output: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
d.getDatabaseMajorVersion(); // output: 11
d.getDatabaseMinorVersion(); // output: 2
d.getDriverName(); // output: Oracle JDBC driver
d.getDriverVersion(); // output: 11.2.0.2.0
d.getDriverMajorVersion(); // output: 11
d.getDriverMinorVersion(); // output: 2
d.supportsGetGeneratedKeys(); // output: true
3) I updated code (its third party component, so not suppose to update :( )
Added third argument whick works fine (it means at runtime it is using older jdbc driver???)
PreparedStatement.setBinaryStream(int, InputStream, (int)length
Please let me know if i am missing anything here... how can i solve this issue?
Thanks!

From my initial post
I am getting AbstractMethodError while calling PreparedStatement.setBinaryStream(int, InputStream) for a BLOB column
3) I updated code (its third party component, so not suppose to update )
Added third argument whick works fine (it means at runtime it is using older jdbc driver???)(3) will not work if correct ojdbc6.jar is used. Because third argument is int and not long. long will work with ojdbc6 but will not work with older version.
I am using third party component and they are using - PreparedStatement.setBinaryStream(int, InputStream)
It should work with JDK 6, Oracle 11g and ojdbc6.jar driver.
I am sure its simple classpath issue or some configuration mismatch - just couldn't see it right now.
I will probably create new workspace / or test on other system now
Thanks!

Java.sql.Blob method setBinaryStream?

Hi,
I've been trying to use the java.sql.Blob methods instead of the "Oracle Extensions" so that people w/o Oracle (using MySQL etc.) can still use my code.
Problem: trying to get the OutputStream to write to the Blob. As of JDK1.4, java.sql.Blob has a method to do this, setBinaryStream. Unfortunately, calling this in Oracle JDBC (tried it in both thin and OCI version) throws an SQLException (Unsupported feature).
Sample code:
//Assume we already have a connection to the database, over either OCI or thin.
//Assume a Statement stmt created from the connection.
//Assume a table BlobTable with 2 fields : id (number) and data (blob).
public void uploadBlob(byte [] theBytes){
     try{
     stmt.executeUpdate("INSERT INTO BlobTable (id, data) VALUES (1,empty_blob())");
     ResultSet rs = stmt.executeQuery("SELECT data FROM BlobTable WHERE id=1 FOR UPDATE");
     if (rs.next()){
java.sql.Blob blob=rs.getBlob(1);
     OutputStream out=blob.setBinaryStream(0);
     //Next line never printed - error thrown.
     System.out.println("Got Stream");
     catch(Exception e){e.printStackTrace();}
//End code
Am I doing something wrong? Or is there simply no way to write to a Blob without using the extensions?
None of the docs (examples, guides, etc) make any mention of this, although the JDBC dev guide does mention that the similar method in PreparedStmt only works over OCI.
Thanks,
Dan

Hi lancea,
It's been a while since this thread was active, but I have a related question.
Is there a comprehensive list of changes between JDBC 3 and JDBC 4 that makes application not work any more, such as this setBinaryStream issue or the CallableStatement/Named parameters issue that we stumbled upon. We would like to address these issues proactively and not find out about them in production, since we're upgrading from jdk1.4 to jdk6. Oracle has provided us with their changes regarding database versions, but have been less forthcoming with JDBC spec version changes.
Thanks in advance,

Problem with inserting two BLOBs into a table using setBinaryStream

DBMS 9.2.0.1.0, Oracle JDBC driver 10.1.0.2.0
The following code insert in one INSERT two BLOBs

inserted into wrong columns.

Oracle.sql.BLOB.setBinaryStream() throws UnsupportedFeatureException

Does anyone know why oracle.sql.BLOB.setBinaryStream(long pos) throws an UnsupportedFeatureException? It seesm to me that if the method were rewritten as:
public OutputStream setBinaryStream(long pos) throws SQLException {
return getDBAccess().newOutputStream(this, getBufferSize(), pos);
... then there would be no reason to throw an exception.
Ideas?
- David

Hi Dave,
I ran into this when I did rs.getBlob(1).setBinaryStream(0) using the ojdbc1_4 driver (without casting to oracle.sql.BLOB). Someone pointed out that I needed to select the BLOB column FOR UPDATE. I did this and now I am getting ORA-01002: fetch out of sequence.
Not sure if I have helped you any...still digging around for the meaning of ORA-01002
Raj

What exactly do I have to put in setBinaryStream(long pos)?

I'm so confused.
Someone put 0L and someone put 1L.
Well oracle jdbc says 0L, but..I'm still confused....
Anybody?

Oooooops.
I'm so sorry, I'm talkin' about the metohd setBinaryStream(long pos) of java.sql.Blob not XXXStatements or ResultSet.
Sorry.
I know the parameter index start with 1 in statements and resultset.
But it's not sure when it comes to say, Blob.setBinaryStream(long pos).
I actually tried with both 0L and 1L,
And the most interest thing is both cases seem to be ok.
When I put 2L, there is an empty byte placed on the first stream.
When I put 3L, there are two empty bytes placed on the first stream.
And so on.
I think (I just think) both 0L and 1L seem to be ok for the first stream.
I coudn't find any clue from jdbc spec through oracle jdbc
ANYbody has ANY concrete solution?

Blob setBytes and setBinaryStream Clarification Needed

I'm writing a JDBC driver for SQL Server and working on the Blob implementation details.
One thing that is not clear in the JDBC spec to me at least is the behavior of the call to setBytes and to setBinaryStream on a Blob.
Say for a simple example I have a Blob with 5 bytes in it ->
1 2 3 4 5
AA BB CC DD EE
So in the database these 5 bytes are stored. I open a Blob on this field.
Then I call setBytes with offset of 3 and write bytes 11 22 33 44
Do I get this ->
1 2 3 4 5 6
AA BB 11 22 33 44 <- Writes over data, also past end of Blob.
Or this?
1 2 3 4 5
AA BB 11 22 33 <- Writes over data, but not past end of Blob.
Or this?
1 2 3 4 5 6 7 8 9
AA BB 11 22 33 44 CC DD EE <- Inserts data at offset, pushes existing data to right.
So in other words, does setBytes insert data at the insertion point, or start overwriting data at the insertion point? Also, does it allow you to keep writing the data in the backend Blob past the end of the Blob?
Same goes for setBinaryStream. The API spec is not clear about the desired behavior.
Thanks for any clues!
Matt

Well... looking at the API...
public void setBytes(int parameterIndex, byte[] x)
throws SQLExceptionSets the designated parameter to the given Java array of bytes.
The driver converts this to an SQL VARBINARY or LONGVARBINARY
(depending on the argument's size relative to the driver's limits
on VARBINARY values) when it sends it to the database.
public void setBinaryStream(int parameterIndex, InputStream x,int length)
throws SQLExceptionSets the designated parameter to the given input stream, which will
have the specified number of bytes. When a very large binary value
is input to a LONGVARBINARY parameter, it may be more practical to send
it via a java.io.InputStream object. The data will be read from the
stream as needed until end-of-file is reached.
It appears that setBytes() you pass in an entire in-memory array
of bytes, whereas setBinaryStream() allows you to pass in an
InputStream that contains the bytes.

When to use setBytes() and setBinaryStream()

Hi,
I am using oracle thin driver to insert a image (blob type) into database.
Which method of PreparedStatement interface should I use to insert data,
setBytes() or SetBinaryStream().
My understanding is BinaryStream also sends data in form of bytes.
Then what is the difference between these two method ?
Please let me know.
Thanks,
-Amol

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

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)

Hi,
but I checked my java version following this steps:
1a - In Windows, Classic View, open the Control Panel and then double-click the Java icon.
1b - In Category View, select the Other Control Panel Options, and then click the Java icon.
2- In the Java Control Panel window click the Java tab, and then click View.
3 - In the Platform column, make sure that version 1.5 or higher exists and that it is enabled.

Why is there a length attribute in setBinaryStream()

Hello,
I am wondering why you have to supply a length attribute in method setBinaryStream(). Normally you do not know the size of the data stream, especially if you create it by marshalling java objects in a separate Thread. For such a case I would like to use the possibility to work with streams when writing to the database. But not knowing the length of the data is a problem. InputStream.available() is not a solution, as it only gets the number of bytes that can be read non-blocking.
The only workaround I can think of is writing in a temp-file, getting its size and creating a new InputStream out of it to write to the database.
Do I miss something here? I think there should be a more elegant solution...
Thanks,
Daniel

I'm using this API with the Microsoft SQL Server 2005 driver (on a SQL Server 2000 database).
Microsoft's implementation of this interface (documented here: http://msdn2.microsoft.com/en-us/library/ms378983.aspx) allows -1 to be supplied as the length parameter and it will read to EOF.
So this code works for me:
PreparedStatement pstmt = con.prepareStatement("INSERT INTO Files ...");
pstmt.setBinaryStream(5, inputStream, (int)size);
It looks like Sun have updated the documentation of this API with JDK 5 also:
http://java.sun.com/j2se/1.5.0/docs/api/java/sql/PreparedStatement.html#setBinaryStream(int,%20java.io.InputStream,%20int)
To quote: "... When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached."
After investigating this lead, I have found this code works also:
pstmt.setObject(5, inputStream);
Perhaps the length parameter was included in the setBinaryStream method in the API because some databases need to allocate space in advance of saving the stream. For those that don't need to allocate space in advance, their drivers might typically accept -1 as the length, and read the stream to the end of file. It's possible that supplying it when it is available might allow the database to allocate space in advance, which might improve performance (this is speculation).
It has taken me a long time to sort out this issue! The main problem was that older API documentation failed mention that it was possible to stream without specifying the length. To anyone in a similar situation - read the JDK 5 API documentation and documentation on your driver's implementation of PreparedStatement.
In summary - I can confirm you don't need to specify the length of a stream for MS SQL Server databases.

Error while iserting a image in DB!!!!!

Hello guys,
I want to insert an image in the DB(MySql). I receive a compiling error when i try to insert an image.
I tried to find in the forums.. but i could not find it..
here is my code..
public void insertImage(String name, String path){
          try{
     ImageIcon icon = new ImageIcon(path);
     Image image = icon.getImage();
        BufferedImage bImage = new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_RGB);
        Graphics bg = bImage.getGraphics();
        bg.drawImage(image,0,0,null);
        bg.dispose();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        ImageIO.write(bImage,"jpeg",out);
        byte[] buf = out.toByteArray();
        ByteArrayInputStream inStream = new ByteArrayInputStream(buf);
          try {
          String query = "insert into instimage(Name, Image) values ('"+name+"',?)";
          PreparedStatement ps = conn.prepareStatement(query);
          ps.setBinaryStream(1,inStream,inStream.available());
          int count = ps.executeUpdate(query);
          }catch (SQLException e) {
               e.printStackTrace();
          }     catch (Exception e) {
               e.printStackTrace();
     The error is
com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near '?)' at line 1I would be grateful, if u guys help me out!!
Thanks

Your query looks like valid. But only if the name variable has good value. If name has value "name with apostrophe'", your code will fail. Try
String query = "insert into instimage(Name, Image) values (?,?)";
PreparedStatement ps = conn.prepareStatement(query);
ps.setString(1,name);
ps.setBinaryStream(2,inStream,inStream.available());

Error while trying to store PDF in Oracle's BLOB field

Hi folks!
I'm having problems while trying to store PDF file in a BLOB field of an Oracle table
This is the message code:
Exception in thread "main" java.sql.SQLException: Data size bigger than max size for this type: 169894
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

at oracle.jdbc.driver.OraclePreparedStatement.setBytes(OraclePreparedStatement.java:2170)
at vgoactualizacion.Main.main(Main.java:84)
This is the piece of code i'm using:
Assuming conn = conection to Oracle 10g Database ( it's working )
String miProcedimientoAlmacenado = "{ call package_name.update_client(?,?, ?) }";
CallableStatement miComando = conn.prepareCall(miProcedimientoAlmacenado);
miComando.setString(1,miClienteID ); //first parameter : IN
               //second parameter : IN
File miPDF = new File(pathPDF + "//" + miClienteID + ".pdf");
byte[] bodyIn = readFully(miPDF); //readFully procedure is shown below
miComando.setBytes(2, bodyIn); //THIS IS THE LINE WHERE THE ERROR IS PRODUCED
          //3rd parameter: OUT
miComando.registerOutParameter(3, java.sql.Types.VARCHAR);
miComando.execute();
private static byte[] readFully(File miPDF) throws FileNotFoundException, IOException {
FileInputStream fis = new FileInputStream(miPDF);
byte[] tmp = new byte[1024];
byte[] data = null;
int sz, len = 0;
while ((sz = fis.read(tmp)) != -1) {
if (data == null) {
len = sz;
data = tmp;
} else {
byte[] narr;
int nlen;
nlen = len + sz;
narr = new byte[nlen];
System.arraycopy(data, 0, narr, 0, len);
System.arraycopy(tmp, 0, narr, len, sz);
data = narr;
len = nlen;
if (len != data.length) {
byte[] narr = new byte[len];
System.arraycopy(data, 0, narr, 0, len);
data = narr;
return data;
}//fin readFully
This approach indicates that the PDF file is converted into an array of bytes, then is stored as binary in the BLOB field.
Thanx in advance, and looking forward for your comments.

You will probably need to use the setBinaryStream() method instead of setBytes().

Setting a null(empty) binary stream in a PreparedStatement

How can I bind a null binary stream into a PreparedStatement?
In the following, if pMap is null how do I bind it? If I try to serialize a null pMap I get and error that not all columns bound.
if(pMap == null)
else
byte[] _bytes = SerializeUtility.serializeObject(pMap);
pStatement.setBinaryStream(pColCount, new ByteArrayInputStream(_bytes), _bytes.length);
Thanks,
David

I was too close to the monitor, couldn't see the big picture ! :-) Now it works.
Although, I still get that Websphere error:
7c7fc721 SharedPool I J2CA0086W: Shareable connection MCWrapper id 31c73d Managed connection comm.ibm.ws.rsadapter.spi.WSRdbManagedConnectionImpl@2e55c73d State:STATE_TRAN_WRAPPER_INUSE from resource jdbc/ds was used within a local transaction containment boundary.
It use to work fine, no errors.
Any ideeas??
