What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

Table Model:: Null Pointer Exception

I have made an application wherein I am using a JTree to display some hierarchy.
Now while scrolling the tree,I display the details in the table.
Data for both the components come from the database.If I continously scroll up and down for some time
in the Tree I get an error in the Table Model
rsmd=rs.getMetaData();
for the above line.It throws NullPointerException,it only happens after scrolling for some time and
not for any particular value.
I update the table model using jtable.setModel().
Plz help.

What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

Select * from table where rownum 5; no rows returned? why is it so?

select from table where rownum > 5;*
no rows returned. why is it so?
can anyone explain me?

Hi,
rownum is pseudo column, and it is based on the sort order.
For ex, if you want to get the first 5 employees who get the least salary, you use,
select ename,sal from
    (select ename, sal
     from emp
     order by sal )
    where rownum<=5
ENAME      SAL
SMITH      800
ALLEN1     890
JAMES      951
TURNER     998
ADAMS      1100Suppose, if you want to use highest salary, you change the order by and not the rownum. So, it becomes,
select ename,sal from
    (select ename, sal
     from emp
     order by sal desc)
    where rownum<=5
ENAME      SAL
KING1      5000
FORD       3000
SCOTT      3000
JONES      2975
BLAKE      2850 So, its not the rownum you would want to change, but the order by.

Insert into table a (select * from table b) - need pk?

Hi there.
I'm going to insert into table FINAL (select * from table STAGING) - same structure but in STAGING the ID column has nulls.
Do I need to provide the ID (primary key) for table FINAL or will it get created based on sequence/trigger?
If I were doing this in a loop I'd get the next val from the sequence but on a simple insert, I'm curious.
thanks!

hmm.. what is ?
it didn't like it.

Returning vector and null pointer exception

Hi, I'm writing a mailing program which so far is working fine, but I have now run into a problem which is completely throwing me. My mailer needs to be able to load multiple attachments - and also to be able to deal with an HTML text which contains multiple images. In each case, what I'm trying to do is to put the attachments and the images into separate vectors and process them through an iterator. The logic, at least, I hope is correct.
I can get my code to compile but it keeps throwing a null pointer exception a runtime. Somehow, I just can't get it to pass the vector from one part of the code to another.
Can anyone help me? I've tried various things, none of which seem to work. My code, as it stands, is posted in a skeletal form below.
Thanks for any ideas:
public class MailSender
   // declare various variables, including:
     Vector embeddedImages;
     String HTMLString;
    public MailSender()
        setup();
    private void setup()
     //this part of the program sets up the various parts of the mail (to, from, body etc)
      HTMLString = "blah blah blah"; //sample HTMLString
       Vector embeddedImages = null; //is this correct?
        if (HTMLString.length() > 0)
            processHTMLString(HTMLString);
     private String procesHTMLString(String htmlText)
        Vector embeddedImages = new Vector(); // I construct my vector here, is this correct?
        //Here I process the HTML string to extract the images
        //get the file path of the image and pass it to the vector
        addToVector(imageFile);
        return HTMLString;
    public Vector addToVector(String imageFile)
        embeddedImages.add(imageFile);
        return embeddedImages;
    private void send()
        //this part does the sending of the mail
        //at some part in this method I need to get at the contents of the vector:
        //but this part isn't working, I keep getting a null pointer exception
        Iterator singleImage = embeddedImages.iterator();
        while (singleImage.hasNext())
    public static void main(String[] args)
        MailSender ms = new MailSender();
        ms.send();
        System.out.println("MailSender is done ");
}

Thank you, salpeter, for your esteemed estimation of my programming competence.
>>>What I'm wondering is: how come people always start building applications... blah blah
The reason being, is that it happens to be my job.
OK, I'm perhaps slower than most and there are things I don't yet understand but I get paid probably about a tenth of what you do (and maybe even less). I regard it as a kind of apprenticeship which, after a past life having spent twenty years packing crates in a warehouse, is worth the sacrifice. Six months ago I'd never written a line of code in my life and everything I've learned since has been from books, the good people in these forums, and a lot of patient trial and error. It's hard work, but I'll get there.
I say this, only as encouragement to anyone else who is trying to learn java and hasn't had the benefit of IT training at school and a four year computing course at university paid for by the parents, and for whom the prohibitive cost (in both time and money) of most java courses would never allow them to get on this ladder.
Excuse my somewhat acerbic posting, but comments such as yours tend to provoke...
Thank you EverNewJoy for explaining this to me. I haven't had time yet to try it out, but at least the concept now is clear to me.

Expression Framework / SELECT * FROM TABLE(CAST(...

Hello!
Is it possible to build the following with Toplink Expression Framework?
Example:
CREATE TYPE TY_OB_TEST AS OBJECT
( SYSTOP_NR NUMBER(5,0)
SYS_NR NUMBER(5,0)
IM_SYS_NAME VARCHAR2(80) ) ;
CREATE TYPE TY_TB_TEST AS TABLE OF TY_OB_TEST;
Package1.FUNCTION1 returns Type TY_TB_TEST.
SQL:
select * from TABLE(CAST(PACKAGE1.FUNCTION1(42)) AS TY_TB_TEST ));
thank you!
Harald.

Nope, just use SQL.

Reason behind this query ,SELECT * FROM table WHERE 1 0

HEllo,
I would like to know the reason behind using this query ,
SELECT * FROM <table> WHERE 1 < 0
before executing the actual SQL query.
Is there any special reason or the JDBC receiver side is configured like that.
Is there any option to overcome this process like, can we remove this option or stop using this.
Why the JDBC adapter basically sending this query on the DB?
Thanks,
Soorya,

Hi,
if you run this query, you wont be able to see any records of the table.
SELECT * FROM <table> WHERE 1 < 0
if you run this query you will see all records
SELECT * FROM <table> WHERE 0 < 1
same with SELECT * FROM <table> WHERE 1=1
So you can check this out that whats happening in your code before executing actual query. just try to co-relate.

Java Null Pointer Exception while Importing a Table to IS

Hello All,
I am trying to import a table into IS and receiving a JAVA Null Pointer Exception. The table is in a Teradata database and I am able to import other tables belonging to the same schema.I get the Java error only while trying to import this one particular table. The DBA has confirmed that the table belongs to the schema/owner I am using. In any case, it seems more of a application error than a database level error. Can anyone provide any insight? Thank you in advance.

hi Keerthi,
thank you.
i tried with below code but still unsuccesfully
+ oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
anyway i'm not able to reach your suggested if statement because execution stops before.
Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
page doesn't give error and saves data.
any suggestion appreciated,
thanx,
N

Null pointer exception while executing a scenario from cloned work repo

Hi,
I have involved in ODI 10g to 11g migration activity.
For doing that activity, i cloned the existing master and work repositories into some intermediate master and work schemas.
Created new configuration settings for pointing the odi 10g to the intermediate master and work repositories.
Everything is fine till this, but while executing any interface or package anything from intermediate work repo designer, am facing error as below

Could anyone pls help on this.
Thanks in advance..

The error is resolved by following the below solution
If you receive an error in ODI 10g like;
java.lang.Exception: Error during Session launching
at com.sunopsis.dwg.dbobj.SnpSession.remoteExecute
or
java.lang.NullPointerException
at com.sunopsis.dwg.cmd.DwgCommandBase.prepare(DwgCommandBase.java)
1.First check whether your agents are working and test connection to repositories. If everything ok, you might have changed your repository name recently.
2.When you export your work and master repository and import to another schema or database and whether you connect to your imported repository, you change your repository name in your first environment.
3.Correct order is first rename your Master Repository name, log off / log on and change your Work Repository name and check below fields in both your Master and Work Repositories in both environments.
Master Repository : SNP_REM_REP
Work Repository : SNP_LOC_REPW
REP_NAME column of MASTER_REP.SNP_REM_REP should be equal to REP_NAME column in WORK_REP.SNP_LOC_REPW.
You cannot see WORK_REP.SNP_LOC_REPW value in ODI Topology Manager and if you are changing your repository name you need to update value from database.
Change the value from DB, loggoff and logon the user and connect the designer again.

Html form for select * from table a

Hi all,
I m looking for report on header/footer part from one apex pages
which will display context from table a, like sql statement
select * from table a, written in html.
Is any examples in java script/html select from tables
(and same insert into table A (...) select * from table b)
thanks,
Gordan

Hello Gordan,
Do you want to show the whole report or just some data of it?
If it's for ex just the name and address you could create two items and have a process or computation to fill it with your select statement.
If it's the whole report, just create the report and put it in for ex. Region 1. In your page template you can specify that Region 1 needs to come into the footer.
Regards,
Dimitri

How do I do SELECT * FROM TABLE WHERE KEY IN ({list})?

The title says it all really.
Is there a reasonable performant way to perform the query
SELECT * FROM TABLE WHERE KEY IN ({list})where {list} is String []?
I am currently creating a PreparedStatement with a for loop like this StringBuffer sb = new StringBuffer ("SELECT * FROM TABLE WHERE ID IN (");
for (int ii=0;ii<keys.length;ii++) {
sb.append (keys [ii]);
if (ii != keys.length-1) sb.append (",");
sb.append (")");but this means that the prepared statement is created each time I call my method and so I'm not sure that the optimizer will find it easy to cope with. Is there a construction that I'm missing along the lines of SELECT * FROM TABLE WHERE KEY = ? where I can create the PreparedStatement once and just call setObject or something on it when the values in {list} change?

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.
You could create several prepared statements which have a common number of bind variables. For example 10 statements with from 1 to 10 bind values. This will work if most of the queries use those.

Select from table containing clob

If i try to select from table containing clob column in SQL PLus it gives error.
Tab1 contains 3 clob columns and 1 blob column
select * from tab 1;
SP2-0678: Column or attribute type can not be displayed by SQL*Plus
The same statement works in SQL Developer and I am able to see the result.
Actually i am writing the queries and they will be used by Java developers in their JSP page.
So what happens here? Can Java use these select statements or will it throw error like SQL Plus?

BLOB column content can't be displayed in SQL*Plus:
SQL> create table t_blob (b blob);
Table created.
SQL> edit
Wrote file afiedt.buf
1* insert into t_blob values('01')
SQL> /
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t_blob;
SP2-0678: Column or attribute type can not be displayed by SQL*PlusBlob and clob columns content can be processed using DBMS_LOB
package procedures and functions or using client's language (like Java)
methods. See JDBC specification.

Select * from table not working with Oracle OBDC driver

Hello,
In our web development we have been using the MS ODBC for Oracle
driver to connect to our Oracle db. We decided to try the
Oracle ODBC driver because it supports the commandTimeout
property in ASP which the MS driver does not. The problem I'm
running into now is that all of our select * from table
statements appear not to be working. The Oracle ODBC driver
version we are using is ver 8.00.05.00. Is there something that
I'm not doing properly? If I take the same select * from table
statement and name the columns, I dont get any error. Otherwise
I'm getting a Subscript out of range error. It seems strange to
me that this driver would not support a select * from table
statement (which I''m told is the case by another developer
here).
Is there something I'm missing?
Thanks,
Pete

I'm positive I have a connection. Otherwise I wouldn't get a
response when I name the columns instead of using *.
There must be something else that I'm missing or doing wrong.
I've actually been looking into alternative ODBC drivers to see
if I have the same problems but none that I have found support
commandTimeout.
Any other ideas?
