About update a blob via JDBC

I want to update a blob value via jdbc.
The following is my program(part)
1)String sqlstr = "SELECT * FROM test WHERE vchar='anyone' ";
2)ResultSet rset = stmt.executeQuery(sqlstr);
3)BLOB blob = ((OracleResultSet)rset).getBLOB(2);
4)OutputStream outstream = blob.getBinaryOutputStream();
when excute the line
#5)outstream.write(...);
A IOException throwed. And said "row containing the LOB value is not locked"
So I change the sqlstr value as
sqlstr = "SELECT * FROM test WHERE vchar='B' FOR UPDATE";
Then ,when I restart the programe,it stoped at the line 2) and nothing tell me.
Just one thing I can do is ctrl-c to corrupt
it.
Can you tell me how to resolve it.
thank you.

Please take a look at this: http://technet.oracle.com/sample_code/tech/java/sqlj_jdbc/sample_code_index.htm
You must do
select ... for update;
even before you manipulate LOB's.

Joe,
a) I could not find updateBlob(int, java.io.InputStream). It is updateBlob(int, java.sql.Blob).
b) I tried the below test and it worked fine, I am using the latest drivers.
CREATE TABLE BLOB_TABLE (C1 NUMBER, C2 BLOB);
INSERT INTO BLOB_TABLE VALUES(55, '101011');
public static void test2(Connection conn) throws SQLException {
System.out.println("test -");
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
String query = "select c1, c2 FROM blob_table";
pstmt = conn.prepareStatement(query, ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
rs = pstmt.executeQuery();
SQLWarning x = pstmt.getWarnings();
if (x != null)
System.out.println(x.getMessage());
x = rs.getWarnings();
if (x != null)
System.out.println(x.getMessage());
BLOB blob = BLOB.createTemporary(conn, true, BLOB.DURATION_SESSION);
byte[] b = new byte[50];
java.util.Arrays.fill(b, (byte) 53);
blob.putBytes(1L, b);
if (rs.next()) {
rs.updateInt(1, 88);
rs.updateBlob(2, blob);
rs.updateRow();
x = rs.getWarnings();

Lost index stats in Ora 8.1.6 Tables when selecting via jdbc

Hi,
i'm using JBuilder8 and Kylix2 on a Linux machine with Oracle oci drivers of client 8.1.7.
The connect through JB8 jdbc via DBPilot is succesful and shows the tables of the db.
After executing a select on any table the index stats of this table are lost.
Kylix works fine without this failure.
Thanks for any comments to this problem
Jens

Well, it's not the PL/SQL code that is causing a problem. Everything worked fine for many months. Then one day (without any changes in the environment or code) the update of a table from a java application (via JDBC) fails. The same update done directly on the DB with SQL Plus still succeeds!
This led us to think that something is wrong with the JDBC connection (which was up for several months). Maybe a memory corruption?
Anyone that experienced similar problems with JDBC?

Update key mapping via web service

Hi ,
I have a question about edit key mapping. The problem is that we create vendors in MDM and syndicate them to different ERP systems. To decide which system a new vendor/changes must be send to, I need the Edit Key Mapping, but the users do not want to enter this information manually and I do not see how I can create key mapping automatically.
We are working on a new solution where vendors are entered in sharepoint and updated in MDM via web services. I would like to know if one of you know if key mapping can be maintained via a web service.
Kind regards
Jonna

Hello,
You may use the document,

How can i put a file into blob using jdbc !?

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
java.lang.UnsupportedOperationException
     at sun.jdbc.odbc.JdbcOdbcResultSet.getBlob(JdbcOdbcResultSet.java:4174)
     at test3.Frame1.saveBlobTableToDisk(Frame1.java:48)

     at test3.Application1.<init>(Application1.java:5)
     at test3.Application1.main(Application1.java:8) "
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.
D.T.

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?

Problem with update of BLOB field in a table with compound primary key

Hi,
I've been developing an application in Application Express 3.1.2.00.02 that includes processing of BLOB data in one of the tables (ZPRAVA). Unfortunately, I've come across a strange behaviour when I tried to update value in a BLOB field for an existing record via a DML form process. Insert of a new record including the BLOB value is OK (the binary file uploads upon submiting the form without any problems). I haven't changed the DML process in any way. The form update process used to work perfectly before I'd included the BLOB field. Since than, I keep on getting this error when trying to update the BLOB field:
ORA-20505: Error in DML: p_rowid=3, p_alt_rowid=ID, p_rowid2=CZ000001, p_alt_rowid2=PR_ID. ORA-01008: not all variables bound
Unable to process row of table ZPRAVA.
OK
Some time ago, I've already created another application where I used similar form that operated on a BLOB field without problems. The only, but maybe very important, difference between both the cases is that the first sucessfull one is based on a table with a standard one-column primary key whereas the second (problematic one) uses a table with compound (composite) two-column PK (two varchar2 fields: ID, PR_ID).
In both cases, I've followed this tutorial: [http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm]).
Can anybody confirm my suspicion that Automatic Row Processing (DML) can be used for updating BLOB fields within tables with only single-column primary keys?
Thanks in advance.

Is there a chance that the bug will be included in the next patch?No, this fix will be in the next full version, 3.2.

Problem with ojdbc14.jar (oracle10g Rel. 2 driver) in updating a BLOB field

Hello All,
Our web application uses oracle10g Release 2 jdbc driver with websphere 5.1.1.4 and oracle 9i. When it tries to update a BLOB field in the database updation is successful but it is updating that field with a null value. So rest of our application fails as this value is becoming null. We use an entity bean to update this table and websphere uses a prepared statement to update this table. Just before setting this BLOB field using setBinaryStream() on prepared statement I am printing to see whether it is null or not as shown in the code snippet below. And it is printing it correctly as non null. But after execution of the prepared statement some how the value stored in database is null.
Is this a known issue with this driver? Does any one know work around or a solution to this? We have 3 BLOB fields in that table. Is that a problem? If we separate these BLOB fields into separate tables will the problem be solved? Any input on this is very much appreciated.
// For column ORIGINAL_CONTENT
byte[] tempbyteArray;
tempbyteArray=(byte[])inputRecord.get(25);
if (tempbyteArray == null) {
System.out.println("DqPageBeanFunctionSet_f9c724af: tempbyteArray NULLLLLLL");
} else {
System.out.println("DqPageBeanFunctionSet_f9c724af: orig tempbyteArray length: " + tempbyteArray.length);
if(tempbyteArray != null) {
pstmt.setBinaryStream(25,new java.io.ByteArrayInputStream(tempbyteArray),tempbyteArray.length);
else pstmt.setNull(25,java.sql.Types.BLOB);
Thanks & Regards,

Inserting and updating a BLOB field

Friends I want my application (Oracle is the backend) to look for a character in a BLOB field and then replace it with the desired character.
Can some one give me some example of retrieving and updating a BLOB field

Examples are in Oracle Technet: http://otn.oracle.com/
In this forum I saw also some examples and in your local Oracle Client Installation you find under $ORACLE_HOME$/jdbc/demo/ examples.

"', Address='" + comp_Addr.getText() +
"', City='" + comp_City.getText() +

ALL_ARGUMENTS information via JDBC Metadata

Hi,
I require METADATA information via JDBC:
* Packages
* Procedure and Functions inside the package
* Arguments with name, datatype,precision,.....
for each package function/procedure
I only found the:
- getProcedures
- getProcedureColumns
but this look like only supporting stored procedure and function
but not package procedures and functions.
Any idea how to get this information ?
In the worst case I have to retrieve the information via all_arguments
dictionary table.
Thanks for your help!

Yes, files opened from SharePoint use a different ASFileSys and you can get info about the location from the ASPathname.
However, no SP-specific information (like metadata) is provided. You would need to use the SP-APIs yourself to do that.

A blob is able to hold files with gigabyte size, a simple 460k file should not cause this JDBC error. I had a test with a 127k file, too, same error (different file types tested: html, doc, pdf, ...). Is this a problem of the driver or is there anythig I am doing wrong?
Many thanks in advance for your help,
Rommie.

My problem is not to retrieve the file but to upload
it. I checked the examples and only saw examples for
retrieving a BLOB or CLOB, but not for inserting it
into the database
Maybe I am blind ... if so, please publish your link
to the example.The page at:

Has a subsection that reads:
LOB Datatype [19-Feb-2003]
The term large object (LOB) refers to a data item that is too large to be stored directly in a database table. This sample application demonstrates how to read and write LOB datatype.The Oracle JDBC drivers provide support for two types of LOBs: BLOBs (unstructured binary data) and CLOBs (character data). BLOB and CLOB data is accessed and referenced using a locator stored in the database table.

The zip is a standalone Java application that will create any needed tables, populate them with example data (both LOBs and CLOBs) from the data files in the zip and then put up a Swing gui that will allow you to add additional LOB and CLOB data to the table. Everything is there, the readme explains the 2 properties files you need to edit. The only other thing besides reading comprehension that you need to supply is DB connection information with the necessary privileges.
The Source link is a link to the main code, but does not include all the code in the package. However, it contains the code to write CLOBs and BLOBs into the database.
The Readme explains everything. It also has code excerpts, including the code used to read the sample data from file and write it into the LOBs and CLOBs.

Question(s) about updating to iOS 5.1.

Hi everyone! I have a few questions about updating my iPod to the iOS 5.1.
First question:
How long will it take? I have used about 8GB worth of memory on it but I have good internet speed.
Second question:
My main computer that I originally had everything set up with doesn't want to work good at all with iTunes, so I switched everything over to my grandma's
computer. So the question is, what will happen to all my music, apps, etc. if I update using my grandma's computer?
Third question:
Do I need to transfer my photo's over? I have over 1,000 photo's on my iPod and I was wondering if I updated would I need to transfer them to the computer
or if they'll manually stay on the iPod.
Fourth Question:
If I update, will I be able to do future updates on the iPod itself without everything being erased like it is with past updates?
Fifth and final question:
Is the kinks in iOS 5.1 worked out yet? I remember when iOS 5 came out they had a miserable time with it and everyone wasn't too pleased, so I'm wondering if
it'll do me any good to update?
I know I sound like a noob, but the last update I did was iOS 4.2 and I don't like doing updates because they take forever with putting everything back on the iPod. They also worry me a bit because I don't want to lose my music and apps (yes I back the iPod up every few downloads but it still worries me lol). Thanks

Downloading the update file can take an hour or more. After it is downloaded the actual update should take between one and two hours, likely closer to one hour.
Second question:

computer. So the question is, what will happen to all my music, apps, etc. if I update using my grandma's computer?
If all the media is on Grandma's computer and in the iTunes library and the computer authrized for the iTunes accounts used then the media will be restored to the iPod during a latter stage of the update if you:
- Connect the iPod to the computer and and make a backup by right clicking one the iPod under Devices in iTunes and select Back Up. Then restore from that backup. The restore will also do the update.
Note that the backup that iTunes makes does not included synced media like aps and music.
Third question:
Do I need to transfer my photo's over? I have over 1,000 photo's on my iPod and I was wondering if I updated would I need to transfer them to the computer or if they'll manually stay on the iPod.
If the photos were taken by or saved to the iPod they are in the backup that iTunes makes. If they were synced to the iPod you have to move them from the old computer to grandma's computer. There are third-party programs that will copy synced photos from the iPod to a computer but you have to pay for them.
Fourth Question:
If I update, will I be able to do future updates on the iPod itself without everything being erased like it is with past updates?
With iOS 5, you can do subsequent updates on the iPod itself via wifi. Nothing is lost (unless something goes amiss)
Fifth and final question:
Is the kinks in iOS 5.1 worked out yet? I remember when iOS 5 came out they had a miserable time with it and everyone wasn't too pleased, so I'm wondering if
it'll do me any good to update?
I have no problems with iOS 5.1. It is improved over iOS 5 and 5.o.1 with the except that sometines the iPod will crash when you try to edit a photo you took.
I know I sound like a noob, but the last update I did was iOS 4.2 and I don't like doing updates because they take forever with putting everything back on the iPod. They also worry me a bit because I don't want to lose my music and apps (yes I back the iPod up every few downloads but it still worries me lol). Thanks
The following also tells you what will happen when you update another than the syncing computer. If you follow with what I said above, it will be the same as updating on yur syncing computer.

Accessing and retreiving ResultSets through CORBA via JDBC

Hey,
Im in the middle of doing a project and I was originally planning to connect to the database through JDBC over TCP/IP only. Everything worked fine. Now Ive been told that I have to use CORBA to relay the result sets over from the remote database. ie An applet requests information, queries the CORBA server, the CORBA server via JDBC then queries the database and gets the result set. The result set is sent back via CORBA to the client applet, where the data is then manipulated.
What I want to know is it actually possible to do this? I only know a small amount of CORBA and Ive been crawling the web for even a small example of it. Could anyone help me out. Ive been looking for the past week and you guys are my last hope.
Thanks in advance

Hi,
You won't be able to send actual instances of the Java class ResultSet via CORBA. All interfaces and data structures you use must be defined in CORBA IDL. You should be able to find a lot of tutorials about general CORBA, including the ones at the bottom of
http://java.sun.com/j2se/1.4.1/docs/guide/idl/index.html
You should define an interface in CORBA IDL for your server that the client applet will call. Probably you'll have a method which takes the query parameters and returns some sort of data structure that you also define in IDL.
The only problem I really see is whether or not the JVM your browser uses does CORBA very well.

I am trying to update my RSS via sound cloud to iTunes but having issues... please help

I am trying to update my RSS via sound cloud to iTunes but having issues.
I currently have my podcast working on iTunes but I have decided to change where I have them hosted. I moved my podcasts over to Soundcloud and currently have the rss feed but I would like to update my iTunes podcast with this so that all my podcasts showing up on sound cloud will sync up and automatically update.
here is my rss feed:
feed://feeds.soundcloud.com/users/48458062-the-collective-podcast/tracks
Podcast via Soundcloud:
http://soundcloud.com/the-collective-podcast
my podcast on iTunes:
https://itunes.apple.com/us/podcast/the-collective-podcast/id662393388
Any help would be greatly appreciated!
Thanks!

The feed in use by iTunes is http://thecollectivepodcast.podomatic.com/rss2.xml , not the one you list. It has one episode, whose media file URL is
http://thecollectivepodcast.podomatic.com/enclosure/2013-06-14T16_06_53-07_00.mp 3
Your feed at http://feeds.soundcloud.com/users/48458062-the-collective-podcast/tracks has no episodes.
You will obviously need to get this sorted out before you can proceed. Once you have the soundcloud feed working properly you will need to add a special tag to the original feed in order to transfer the Store to using the new feed. The method is decribed here:

Please make sure you are completely clear about it before proceeding, and check that the new feed works by subscribing manually in iTunes before you try moving the Store to it.
