Scrollable Result Set in Oracle 8.1.6 ?

The Oracle8i Release 2 New Features Summary says::
JDBC 2.0 core support plus connection pooling and distributed transactions.
My Question is : 8.1.6 provide full JDBC 2.0
Support or just some features not specified?
Is there support for an scrollable Result set ?
I hope somebody can answer
thanks ITDEVEL

Java.lang.Exception: org.hibernate.AssertionFailure: scrollable result sets

Hi All,
I am using Oracle 11g and I am trying to delete some records from database using some GUI. In that case I am getting following error:
java.lang.Exception: org.hibernate.AssertionFailure: scrollable result sets are not enabled. When I restart the application's service, this error is going away and deletion is working fine.
Other related jars that I am using is as follow:
ojdbc5.jar
hibernate-3.0.5.jar
I am attaching the stack trace as well:

Scrollable result set fails with doubles

Hi there,
i have a strange behaviour using the 10g thin JDBC driver:
Using a scrollable result set the driver fails reading a BINARY_DOUBLE value from the result set with rs.getDouble(column) as long as the value is not null. The SQLException reports "Conversion to double failed".
When i use a forward-only result set instead, the value can be retrieved without any error. Can anyone explain this or give a workaround?
Thanks in advance,
Thorsten

ThorstenS,
ScrollableResultSet stores BINARY_DOUBLE column as oracle.sql.BINARY_DOUBLE & since, oracle.sql.BINARY_DOUBLE does not have method to convert to double you are seeing this error.
The workaround would be to do,
rs.getBINARYDOUBLE(1).stringValue()
& please file an enhancement request against Jdbc.

I'm using hibernate 3.2.2.ga and oracle 10g
Can someone help me? How can I solve this problem?

Scrollable result sets

I need a scrollable resultset. I have never had to use one before. I have research this some what. I am usin the following statement which i reference from the Sun site:
Statement stmt2 = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE);
Problem is, I receive a "cannot resolve symbol"
message when it tries to compile. Anyone have any ideas?
Thanks.

connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
OR.
connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE );
make sure your driver(jdbc) supports the Scrollable drivers .
all drivers can't support this type of result set.
Oracle ThinDriver class12.zip will support this.
and also some drivers will support.

Please help - Scrollable result set in sql server 2000

Hi can some one please help me. I'm trying to create scrollable result set in sql server 2000, but i just can't get it to work. I've been trying to do this for the past 12 hours. I want to go home, but I can't till I get this going! please help!!! My crap code is as follows:
package transact;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.JInternalFrame;
import java.sql.*;
import java.io.*;
import java.util.*;
public class DummyFrame extends Dummy

public DummyFrame()
createFrame();
private void createFrame()
try
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://server:1433;" +
"user=user;password=pwd;DatabaseName=Northwind");
catch (Exception e)
e.getMessage();
populateFields();
menuAction();
show();
private void menuAction()
btncontacts.addActionListener(new ActionListener()

getRecords();
populateFields();
btncontacts.setText("NEXT");
btnkeywords.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
// transaction.getRecords();

populateFields();
btncontacts.setText("NEXT");
protected void nextRecord()
try
// CallableStatement cstatement = null;
cstatement = conn.prepareCall(
"{call Employee_Selection}", ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = cstatement.executeQuery();
while (rs.next())
surname = rs.getString("Lastname");
cstatement.getMoreResults();
catch (Exception e)
e.getMessage();
protected void getRecords()
try
CallableStatement cstatement = null;
cstatement = conn.prepareCall(
"{call Employee_Selection}", ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = cstatement.executeQuery();
while (rs.next())
surname = rs.getString("Lastname");
name = rs.getString("Firstname");
rs.first();
// call stored procedure
catch (Exception e)
e.getMessage();
// populate the fields;
private void populateFields()
txtfirstname.setText(name);
txtsurname.setText(surname);
}

ummm ok i think the logic in your code is kinda screwy...
here is what your should be doing.
create the gui.
get the resultset...
have code that looks like this for nextRecord...
protected void displayNextRecord(){
// we do not call next here because we already called it last time
surname = rs.getString("Lastname");
name = rs.getString("Firstname");
populateFields();
if(!rs.next(){
btncontacts.setEnabled(false);// i'm not sure what btncontacts is but we want to disable next becuase there are no more records...
// in your intitalization code you need to do this...
// you old stuff ending with...
ResultSet rs = cstatement.executeQuery();
// the new stuff...
if(rs.first()){
displayNextRecord();
}else{
btncontacts.setEnabled(false);//the result set is empty
}ok the real problem you are having is that you are trying to display one record at a time but you are scrolling
through the entire result set using while(rs.next()... what you
want to do is create the result set once and scroll through
it one item at a time with your gui.
the example method i have given displays the data from the current
row in your gui. then it advances the result set forward one row if possible. this method assumes that the result set will always
be positioned on a valid row thus the need for calling
rs.first() before we originally call displayNextRecord()
well i hope you find this helpful.

Updateable scrollable result sets with join statement

I am writing a generic GUI fronend for any database that has a JDBC2.0 driver available.
I have been using scrollable updateable result sets. These work well for individual tables but as soon as two tables are linked either implicitly or explicitly with a join statement the result set meta data isDefinitelyWriteable is set to false thus preventing the result set from being updated.
Assuming I am using the JDBC-ODBC driver with java sdk1.4.0 and MS Access (although I have used other databases and JDBCs I assume that the one mentioned will be a common combination and needs to work) is there any way of getting linked tables to be updateable with scollable result sets.
I am using scrollable result sets since this prevents the necessity of putting the data in a secondary data store.
I am able to link tables programmatically by requerying the linked table with a new where clause each time the cursor moves in the linked table but this seems rather wasteful. This method is not vey satisfactory when attempting to display data from more than one table which have more than one linked level (i.e. cascaded links).
Is there a simple solution to this problem or do I have to do a rewrite using an update statement instead of having an updateable result set. I assume this method would also require the result set to be reloaded after the update.
Any suggestions much appreciated.

I am trying to make the GUI as flexible as possible by constructing "views" which if necessary link tables on one field in each table. This is fine for two tables but when linking to several tables the information thats produced cannot be read easily because as it stands the information from each table is displayed on a separate tabbed page. This mechanism allows me to keep each record set for each table separate and updateable.
Since I could see that this was not very user friendly in the way that it displayed the data I decided to try and introduce a join on two or more tables and hence the introduction of the current problem.
I mentioned that the objective was to be flexible and therefore I also allow queries to be written by the user to facilitate for any shortfalls of the automatic query construction produced by using the "views" mechanism.
So the answer to your question is yes I do control the SQL selections with one mechanism but ultimately no I do not because I provide a fail safe which allows the user to enter arbitary SQL.
I only really want a solution for the controlled SQL construction mechanism where I create the link between two or more tables. As mentioned earlier these are linked on one field only but I wish to provide the option of displaying the result in a single table (tabbed page) rather than spread across multiple tabbed pages.

Scrollable Result Set

I am trying to use a scrollable result set in Java so that I can page the result set on the client at 150 records at at time. The problem is, when there is lots of rows (200K+) the client running the query runs out of memory. To solve this, I limited the rows using setMaxRows(30000). I would like to not have to limit it in this way, but I can't seem to find a solution. Also, since I want to be able to page through all rows, no matter how many, is it possible that the select statement will crash the server at some point as well (if it is a SELECT * FROM TABLE)? If say there were millions of records? How do people solve these kinds of situations?
String query = "SELECT * FROM EventDetail";
Statement stmt = con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY
stmt.setMaxRows(30000);
rs = stmt.executeQuery(query);

Hi,
u can use rowcount for making ur results scrollable. just use one variable for page no. Example
select position,empno,empname FROM (select rowcount position,empno,empname from employee where rowcount < (pageno*pageno)
Thanks,
Harish

Did you forget to put the SQL statement in when you used createStatement? I added it below:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("Jdbc:Odbc:IMSMC","sa","");
String sql="select * from <Table Name> ";
Statement stmt=conn.createStatement(sql, ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
Does the JDBC-ODBC bridge driver accomodate any of these settings you're trying?
The problem shouldn't have anything to do with Tomcat. Sounds like a JDBC driver issue to me. Try to reproduce the error without Tomcat, and then see if adding the SQL corrects things at all.
I'd read the docs to see if the bridge driver has these features. I don't think it's up to the full standard.

Java.sql.Statement.setFetchSize(int) option for non-scrollable result sets

Hello!
Our tests indicate that fetch size option mentioned makes visible difference in performance for non-scrollable result sets also. In the same time, it seems there is no way to set this option for such result sets at TopLink level, and default fetch size is always used instead.
Can somebody propose a solution for this, I mean a way to specify custom fetch size (for results without any scrolling)?
Thanks,
Sergey

To set the JDBC fetch size for a query, use the following APIs:
int desiredFetchSize = 500;
ReadAllQuery query = new ReadAllQuery(YourClass.class);
CallQueryMechanism queryMechanism =
(CallQueryMechanism) query.getQueryMechanism();
DatabaseCall call = queryMechanism.getCall();
call.setResultSetFetchSize(desiredFetchSize);
If you wish to set the fetch size for all queries, consider using named queries for all queries (see the TopLink documentation for more information on named queries), and then configure them on startup.

Database driver that allows scrollable result set

I attempted to create a scrollable result set with the following create statement.
s = c.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
I received the following error at runtime.
java.sql.SQLException: [Microsoft][ODBC Visual FoxPro Driver]Driver not capable
Anyone know of a Foxpro driver that supports scrollable result sets or another solution to this problem.
Thanks,
Brian

I don't know if you just mistyped your original question, but to create a scrollable resultset you have to give it a the statement constructor a ResultSet.TYPE_SCROLL_INSENSITIVE parameter:
s = c.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);maybe your driver does not support ResultSet.CONCUR_UPDATABLE??

Problem with scrollable result set

hi
can u please tell me how i can get no of rows from a result set..
i am using thin drivers and connecting to remote database,every thing is working fine if i use fwd only type ,but if u use sensitive type it is giving error
code:
stmt=con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
i am geting error at this line
error :
java.lang.AbstractMethodError:oracle/jdbc/driver/oracleconnection.createStatement
please help me

does your jdk include jdbc 2.0? Is your driver updated to support jdbc 2.0 features? have you recently updated either(and forgot to change the classpath)?
I am running jdk 1.3 and oracle thin(classes12.zip) have not had problems creating/using scrollable resultsets??

Can I retrieve a result set from Oracle and then incorporate that result set into my main SQL Server Stored Procedure?

So I have a chunk of data that only resides in Oracle. So I need to capture that information from Oracle. Now before you get over zealous, I did try with an OPENQUERY and it took FOREVER! And I don't know why the OPENQUERY took FOREVER but if I run the same
query directly against Oracle it runs very quickly...like 20 seconds.
So now I'm wondering...can I build a dataset in my SSRS Report that uses an Oracle Data source and an Oracle Stored Procedure in its Dataset that I'll create to aggregate this subset of data and then utilize its result set back in my main reporting
Dataset that will utilize SQL Server? And how can I do that? Can I make my main Dataset reference, say, a #TemporaryTable that is created from my Oracle Dataset in its
I'll continue to Google a few things as I await your review and hopefully a reply.
Thanks in advance for your help.

Hi ITBobbyP,
According to your description you want to use data from a Oracle data source into a DataSet which retrieving data from SQL Server. Right?
In Reporting Services, we can have multiple data sources in one project pointing to different database. And we can use separated dataset to retrieve data from different data source. However, it's not supported to combine the two datasets together
directly. We can only use Lookup(), LookupSet() function to combine fields from different dataset into one tablix when there are common columns between two datasets. This is the only way to make tow result sets together in SSRS.
Reference:
Lookup Function (Report Builder and SSRS)
LookupSet Function (Report Builder and SSRS)

Scrollable result set in PDK How?

is there any standart possibility
to work with cursors?
or only i can do to store entire
limited result set(in XML m.b.)
and send back demanded part
if so when collect garbage?

O'Rix,
I am not sure if I understand your question. But, if you are asking if you can use cursors in the PDK, yes, in a Database portlet you can.

Oracle JDBC Thin Driver Memory leak in scrollable result set

Hi,
I am using oracle 8.1.7 with oracle thin jdbc driver (classes12.zip) with jre 1.2.2. When I try to use the scrollable resultset and fetch records with the default fetch size, I run into memory leaks. When the records fetched are large(10000 records) over a period of access I get "outofmemory" error because of the leak. There is no use increasing the heap size as the leak is anyhow there.
I tried using optimizeit and found there is a huge amout of memory leak for each execution of scrollable resultsets and this memory leak is propotional to the no of records fetched. This memory leak is not released even when i set the resultset,statement objects to null. Also when i use methods like scrollabelresultset.last() this memory leak increases.
So is this a problem with the driver or i am doing some wrong.
If some of you can help me with a solution to solve this it would be of help. If needed i can provide some statistics of these memory leaks using optimize it and share the code.
Thanks
Rajesh

This thread is ancient and the original was about the 8.1.7 drivers. Please start a new thread. Be sure to include driver and database versions, stack traces, sample code and why you think there is a memory leak.
