Update problems with jdbc on access db too

hi..
i have a strange problem with updating a record in ms-access - db by using jdbc.
my program creates a "correct??" update-statement but i get an error-message: errorcode:3144.. syntaxerror in update-statement or something like that..
thats the statement that my program creates:
update maX2 set m1='super',set m2='hallo' where id=2
java-code:
Statement stmt = con.createStatement();
stmt.executeUpdate(... the update-statement ...);
does anybody know why i get this errormessage?

Your statemente should be:
update maX2 set m1='super', m2='hallo' where id=2

I have a problem with JDBC Realm in Tomcat/Oracle/Win XP

I have a problem with JDBC Realm in Tomcat.
I have attached my server.xml file located in the
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\server.xml
The Problem is that when I login I get the user name and password prompt but it does not resolve.
When I enter in the tomcat-users.xml password with memory realm uncommented it works fine.
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml
Is there a cache or something I need to reset for the JDBC Realm to work?
I have attached my tables and contents as well...
Did I miss something????
Thanks
Phil

I have a tesco router and an external hard drive attached to it as a network drive (shared) for my macbook and MB-Air. Have no problems with my MB accessing it, but with MB-AIR it says - 'the version of the server you are trying to connect to is not supported. pls contact your system administrator to resolve the problem'. MB-Air uses maverick downloaded yesterday - upgrade from mountain lion. MB uses snow leopard still, as i am quite used to it and am thinking of upgrade if mavericks work fine on air. Also have parallel on snow leopard but it is no longer supported according to mac website - if i upgrade am i going to lose my parallel and will have to buy a new one!!!

Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

A problem with a session Access

Hi Olivier,
To connect with Forte while running distributed you must use System DNS
instead of User DNS on the server. The ftexec.exe on your server partition
will be launched by the NodeMgr running as UID SYSTEM. User DNS are not
available to processes running as UID SYSTEM.

I do not recommend reformatting your harddrive and reloading your software. This is a Windows thing. On an older mac it may be difficult to find all your software again.
Best to have greater than 2gig of free space. Many posters to these forums state that you need much more free space: 5 gig to 10 gig or 10 percent of you hd size.

Be careful when deleting files. A lot of people have trashed their system when deleting things. Place things in trash. Reboot & run your applications. Empty trash.
Go after large files that you have created & know what they are. Do not delete small files that are in a folder you do not know what the folder is for. Anything that is less than a megabyte is a small file these days.

$200 reward to solve problem with JDBC and CLOB.getCharacterOutputStream

I'm trying to update CLOB with the getCharacterOutputStream as suggested in the example code. It works with US7ASCII DB instance but not instances in UTF8.
I've been browsing through all the Oracle doc's and found some rather confusing statements:
In the page at http://oradoc.photo.net/ora816/java.816/a81354/oralob2.htm#1043220
it says: [When writing to or reading from a CLOB, the JDBC drivers perform all character set conversions for you.]
also: [The oracle.sql.CLOB class supports all the character sets that the Oracle data server supports for CLOB types.]
So far so good.
In the page at http://oradoc.photo.net/ora816/java.816/a81354/oraint3.htm#1012518
it says [The oracle.sql package supports these datatypes in several ways: CLOBs point to large fixed-width character data items (that is, characters that require a fixed number of bytes per character) and are supported by the oracle.sql.CLOB class.]
Ooh no! Is this for real? UTF8 is variable width and does this mean it is not supported?
Any way to get around this?
In the page at http://oradoc.photo.net/ora816/java.816/a81358/03_pub2.htm#36009
says [6.The mappings to oracle.sql classes are optimal because they preserve data formats and require no character-set conversions (apart from the usual network conversions). Those classes are especially useful in applications that "shovel" data between SQL and Java.]
"No character set conversion"? Very confusing!
I've been hammering on this CLOB/JDBC/UTF8 problem for more than a week now and I really appreciate some solutions, workarounds, or whatever help I can get. I'm running java stored procedure in 8.1.6 on Linux RH6.2.
For your trouble, I'd pay $200 for the first guy who come up with a verifiable solution.

This is just findings based upon your comments:
Please refer to document Oracle8i National Language Support Guide
Release 2 (8.1.6) from Oracle Documentation Library, Release 8.1.7
Chapter 6 Java,
There its clearly mention that:
"Oracle JDBC drivers provide globalization support by allowing users to retrieve data from or insert data into a database in any character set that Oracle supports. Because Java strings are UCS2 encoded (16-bit Unicode) for JDBC programs, the target character set on the client is always UCS2. Character set conversion is required to convert data from the database character set (Db Charset) to UCS2. This applies to CHAR, LONG, CLOB, and VARCHAR2 data types; RAW data is not converted. "
Also..please refer this...
"oracle.sql.CLOB's method getCharacterStream() returns the contents of a CLOB as a Unicode stream."
"The techniques that Oracle's drivers use to perform character set conversion for Java applications depend on the character set the database uses. The simplest case is where the database uses a US7ASCII or WE8ISO8859P1 character set. In this case, the driver converts the data directly from the database character set to UCS2,which is used in Java applications. "
"If you are working with databases that employ a non-US7ASCII or non-WE8ISO8859P1 character set (for example, Japanese or Korean), then the driver converts the data, first to UTF8, then to UCS2. "
In my case the characte-set of the database is WE8ISO8859P1 and for security reason i can't change the character set but my feeling is that if you are updating the CLob from the java client you are forming a reference of a clob in the client which is UCS2 at the Java side. Now when you are populating the clob through java.io.Writer and call the procedure to pass the reference of the clob to the procedure then I believe the JDBC will convert the UCS2 datatype of Clob to UTF8 in the database.

Update problems with itunes 10.6.1 on xp

When I try to update to iTunes 10.6.1 n Windows XP sp3 I get the dialog box to repair or remove. If I select repair the update fails. Any ideas on how to correct this issue?

I have an old macbook too.
It seems like Apple writes new software that makes older computers not work as well.
I always have reservations about updating with an older model.
Does anybody else have any problems with the new iTunes?

There are numerous problems with what you posted.
1) Do you mean to use updateNull and not what you are doing?
2) As mentioned why would you not do this in an UPDATE query? Even if you get this to work arbitrary moving around in a result set that you don't even need along with bad practices like SELECT * is just bad all around.
3) Further as mentioned what you are trying to do is not supported (obviously) by your driver/database etc. Just because you ASK for a scrollable updatable cursor does not mean that you get one. You ask for one but obviously that error message says that the cursor is read only. For the benefits of others it says (more or less) "invalid operation on read only result set : updateBlob"
Possibly you will have to use a forward only cursor to make it updateable... I don't know consult the Oracle docs. Or better yet don't do it this way.

Update problem in JDBC

Hi,
I am using mysql with JDBC , and I try to execute a update like this:
update tablename set doc="function test(){ var test; test=1;return test;}" where DocId='11';
It is work well in mysql console. But when i run it in program use JDBC, the result in database field Doc in row where DocId='11' is :
function test() var test; test=1; return test; {}
I didn't know who change the "{ " location ?
How to solve this problem?

Hi,
Maybe the driver thinks it's some kind of escape
sequence, but I still don't see why this happens. Just
an idea, maybe it helps.
Alin.Mr Ace169,
Thank you for your reply. I also think that { must a escape sequence . Could you tell me where can i find the escape sequence for JDBC of mysql?

Problem with JDBC Connection for HDB hanadb 02

Hi folks,
Ok I have an instance based on the 7.4 SP5 HANA CAL solution.
But when I suspend and restart the R3 system doesn't start again.
I've followed the instructions in the user guide and can access the backend instance and see that for HDB GetProcessList everything is GREEN, running
while for A4H GetProcessList everything is GREY, stopped
When I try to start the A4H instance I get
Checking HDB database
Database is not available via R3trans
Database must be started first
The messages I found on SCN suggested this might be a license problem with the HANA database, so I tried to follow the install license instructions for the HANA database via the HANA studio, but when I try to open the HDB(SYSTEM) > Properties > Licence, I then get the messages
Error while reading the licence information from system HDB hanadb 02
Reason:
Cannot retrieve JDBC Connection for HDB hanadb 02
So what do I try now?
Any suggestions?
Rgds,
Jocelyn

Thanks Ivanka! That sorted it.
For the benefit of others...the error message was found in the server log files
/var/log/applianceagent.log

Problem with JDBC and Tomcat

I don't know where the problem originate, the only thing in my memory is that the program worked very well on my PC yesterday, but today, without even slightest change, it doesn't work anymore. As to debug it, I simplified the codes to the least, but it still refuse to work. I was beaten down by this problem totally, and cannot make out any solution for it, so, I come here, hoping to find a warrior to kill this damned bug for me.
My program is a Servlet, but for the purpose of debugging, I have recode it to an Application/Servlet. When run as a application, I can get the result expected, but as a Servlet, :-(, maybe you should see it by yourself. My server software is Tomcat 4.1.15, and the JDK version is 1.4.0. To excute this program, you should add Data Source "Test" to ODBC.
///////////////////////code begins/////////////////////////
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Ex extends HttpServlet
 int ErrorType = 0;
 String err = new String("");
 public static void main(String args[]) throws Exception{
 Ex cEx = new Ex();
 cEx.init();
 System.out.println(cEx.ErrorType);
 public void init() {
 String url = "jdbc:odbc:Test";
 ErrorType = 3; //passed
 try{
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
 } catch (ClassNotFoundException e) {
 e.printStackTrace();
 ErrorType = 1; //trapped in Class.forName
 try{
 Connection c = DriverManager.getConnection(url);
 } catch (SQLException e) {
 e.printStackTrace();
 ErrorType = 2; //trapped in DriverManager.getConnection
 err = e.getMessage();
 public void service(HttpServletRequest req, HttpServletResponse res)
 throws IOException {
 res.setContentType("text/html; charset=GB2312");
 PrintWriter out = res.getWriter();
 out.println("Success " + "" + ErrorType + "" +err);
 out.close();
//////////////////////////code ends///////////////////////////////
The result from the Servlet tell me that the problem occurred within the connection process, I don't know who should be responsible to this - Tomcat or JDBC?

If you could print the exception that you got then that would help :) In the mean time, I could make a guess. It is unlikely that your application server (in this case, Tomcat) is blocking connections from your servlet. So the problem is either with JDBC directly or with the underlying datasource. It seems unlikely that it is JDBC given that you have stated that the code has not changed and it works in application form.
My guess would be that you are coming up against some sort of security constraint (eg: your DBMS is letting you log in from one IP but not another?, your Java plug-in security policy is disallowing the connection?). It's hard to say.
But if it works as an application but not via a servlet then you could try putting this in your java.policy file, which is located in the directory where your plug-ins are installed (eg: "C:\Program Files\Java\<version>\lib\security\") on Windows systems;
permission java.net.SocketPermission "bend xp:1099", "listen,connect,accept";
Try that, see if it works :)
