Jdbc Result Set

I would like to find out how to break a large result set (say 1000 records) into smaller blocks (say 50)!! Just like some of the web sites where you can view the first 50 results, then press a button to see the next 50...
Any input will be appreciated!!
Thanks.

There are many ways to do this. You could write your query to return a subset of the results, say 25-50, 75-100, etc. You could write a SQL procedure that does this for you. You could get all the rows of the result set and store them in the session, or memory, as a Vector and only display the ones you're interested in.

RDBMS Event Generator Issue - JDBC Result Set Already Closed

All -
I am having a problem with an RDBMS event generator that has been exposed by our Load Testing. It seems that after the database is under load I get the following exception trace:

I have tried several things and had my team do research but we have not been able to find an answer to the problem.
If anyone can offer any insight as to why we might be getting this error it would be greatly appreciated. Thanks!

i also have same error during load testing, mainly this error
"Unexpected exception while enlisting XAConnection java.sql.SQLException"
i tried rerunning after increasing connection pool sizes, transaction timeout, but no luck, marginal improvement in performance though
also tried changing the default tracking levl to none, but no luck.
i am with 8.1SP5, how about you ?
do share if you are able to bypass these errors

Oracle Coherence implementation for JDBC result set

Instead of ORM, is Oracle coherence will support for accessing the data using normal JDBC calls?
If it supports JDBC , what is the CacheStore implemetation for this?
Can you provide me some example how to cache the JDBC ResultSet values and retrieve back from Cache?

Hi,
I think you mix up several concepts.
user13266701 wrote:
Instead of ORM, is Oracle coherence will support for accessing the data using normal JDBC calls?At the moment (up to 3.5.x), there is no way to query Coherence via JDBC out-of-the-box. There were a couple of initiatives to provide such features but they were not part of the product, only initiatives in the Incubator, but I believe they have been dropped.
Upcoming releases may bring replacement, although I don't think it would be outright JDBC compatible, as that would imply converting an object-oriented data to result set so that you can convert it back, so it would in effect waste CPU resources.
If it supports JDBC , what is the CacheStore implemetation for this?
CacheStores have nothing to do with how you access the cache itself. Those are internal operations invoked by Coherence itself. Don't look for a relationship between querying the cache and doing anything with the cache store. The only relationship with them is that key-based operations on the cache may lead to operations on the cache store, but whether they do happen or not depends on the cache content, too.
Can you provide me some example how to cache the JDBC ResultSet values and retrieve back from Cache?If I understand, that is yet a third concept. If you indeed want to cache JDBC ResultSet-s obtained from the database, then I have to disappoint you: it is not directly possible, as the ResultSet object is an abstraction over an open database cursor, and hence it keeps a database resource. Active resources cannot be cached in Coherence. You may acquire a RowSet from the JDBC driver, which would be possible to cache, however it may not be the most efficient thing to do due to possibly not optimal serialization format used by the RowSet to serialize itself.
So if I did not answer the questions you wanted to ask, would you please explain in more detail what exactly you would like to do?
Best regards,
Robert

JDBC Result Set from Non-Database Source

In Java, is it possible to create a result set from a non-database data source?, for example an XML file, text file, vectors, java beans
We have a Swing application that currently makes direct JDBC calls to the DB2 database for creating result sets. We want to replace JDBC calls with calls to web service, but want to still create result sets on the client, so the replacement of the datasource from database to web service call is transparent to the rest of the code.

It is fairly easy, although somewhat tedious (many methods,) to create a new type of ResultSet.
But if the above application is doing SQL via statements and expecting the result via a ResultSet then you are not just creating a ResultSet but an entire driver and one that will have to deal with SQL as well. And if you have to handle the SQL itself that means you will probably need a parser and interpreter.

JDBC Result Set Control

In Oracle JDBC, when I retrieve data from Oracle server, I would like fetch page by page instead of all the data returned, and allow user scroll up and down.
How can I do this in Oracle JDBC?
Thanks,
null

But compiling it otherwise fails?
Yes..it is progress..your event handling is using deprecated methods..if you compile with the deprecation flag, it will tell you where you used them, and compile... at least that way.
Also..look into java.awt.event.* (Listeners and such)..
The basic way they work is this:
1- Implement a Listener interface (ActionListener, XYZListener, MouseListener, whatever).
2- Implement the methods from that interface (for ActionListener and buttons it is public void actionPerformed(ActionEvent ae))
3- Add your listener to the GUI element (( element.addActionListener(this); ))
There is documentation as well.

Abt jdbc result set

Hi frendz,
I have lakhs of records (around 1 GB)in database. I have to access them according to the time stamp. I have to access them. But u no problem of memory, So is it possible to retrieve the records in numbers of hundres??
thanq
chandu

I thnk PreparedStatement is for insertion of records.
Isn't it? I m not sure abt it.How about looking it up if you're unsure? It does whatever you tell it. And it returns a ResultSet when you run a query which is, as I already pointed out something like a pointer on a view of the selection. It may contan as many records as you like, it doesn't load any of them into the memory.

Eliminating null from result set

Hi,
How can i set some value (say 0) for fields having null value using ejbql?
Anybody please help me....
Thanks in Advance,

what is the best way to get from a jdbc Result Set to
a Swing Table Model?I think I would iterate over all the elements in my result set and add them to a hashmap / hashtable where the key is their spot in the table, represented by a Point object. One thing I'm not sure of is if 2 points with equal coordinates have the same hash value, but you could always just create your own point class where such is the case and use that.
Result Sets are no random access structures. You have
to navigate through them to reach a certain row.Yes. Not only that, but the resultset is part of your transaction with the DB. It's not good style to keep that open any longer than necessary.
JTable Models want you to implement something like
getValueAt(int i, int j) to access a row (and even a
column) at random.Would be easy using my suggestion above
- your are in fact interducing another cashKind of. But you don't have a choice. You gotta copy the data.
- big Result Sets could be a problemThat's always going to be true, and I don't see how you can get around it.

Avoid JDBC sender error: Execute statement did not return a result set

Hi!
My JDBC sender adapter towards MS SQL server works fine, with an Execute statement calling a stored procedure that returns the source data needed. The stored procedure itself updates the status of database table records, so that only the unread records are returned each time the stored procedure is called.
However, the communication channel monitoring sets a red flag for the JDBC sender adapter, when there are no values to fetch from the database table (using the stored procedure). Message says: "Database-level error reported by JDBC driver while executing statement 'EXECUTE FetchMessage 1, 9000'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor."
This is not an error situation, as I do not expect there to be any values to fetch from the database at all times.
I do not see how to change the stored procedure to avoid this error.
Is there a parameter to be set on the JDBC adapter that I can use, so the red flag is avoided?
Thanks for any input!
Regards,
Oeystein Emhjellen

Hi Oeystein Emhjellen.
The problem is Store Procedure that has to generate always a ResultSet (or cursor). If it doesn't have a output, you have to generate an Empty ResultSet.
Like a SELECT Statement:
If there are data, SELECT get an output result but if it get nothing the SELECT Statement get a empty ResultSet.
Ask to your database team.
I hope it helps you.

JDBC-ODBC Bridge to SPSS data files - Result Set Type is not supported

Hello,
As mentioned in the subject I am trying to read SPSS data files using the SPSS 32-Bit data driver, ODBC and the JDBC-ODBC Bridge.
Using this SPSS Driver I manged to read the data directly into an MS-SQL Server using:
SELECT [...] FROM
OPENROWSET(''MSDASQL.1'',''DRIVER={SPSS 32-BIT Data Driver (*.sav)};DBQ=' SomePathWhereTheFilesAre';SERVER=NotTheServer'', ''SELECT 'SomeSPSSColumn' FROM "'SomeSPSSFileNameWithoutExt'"'') AS a
This works fine!
Using Access and an ODBC System DNS works for IMPORTING but NOT for LINKING.
It is even possible to read the data using the very slow SPSS API.
However, when it comes to JDBC-ODBC the below code does only work in part. The driver is loaded successfully, but when it comes to transferring data into the resultset object the error
SQLState: null
Result Set Type is not supported
Vendor: 0
occurs.
The official answer from SPSS is to use .Net or to use their implementation with Python in their new version 14.0. But this is obviously not an option when you want to use only Java.
Does anybody have experience with SPSS and JDBC-ODBC??? I have tried the possible ResultSet Types, which I took from:
http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/ad/rjvdsprp.htm
and none of them worked.
Thank you in advance for your ideas and input & stay happy!

Thank you for your reply StuDerby!
Actually the above script was before, as you suggested, leaving the ResultSetTeype default. This did not work...
I am getting gray hair with SPSS - in terms of connectivity and "integratebility" none of their solutions offered is sufficient from my point of view.
Variable definitions can only be read by the slow API, data can only be read by Python or Microsoft Products... and if you want to combine both you are in big trouble. I can only assume that this is a company strategy to sell their Dimensions Platform to companies versus having companies developping their applications according to business needs.
Thanks again for any furthur suggestions and I hope, that some SPSS Developper will see this post!
Cheers!!

JDBC SQL Server Channel Calling Stored Procedure Won't Return Result Set

Good afternoon, Experts
We're calling a stored procedure in a sender communcation channel. I can perform any SQL SELECT statement here, but for some reason when I execute the SP (EXECUTE StoredProcedureName) The Adapter Engine returns the following:
Database-level error reported by JDBC driver while executing statement 'DECLARE @UpdateRecords bit SET @UpdateRecords = 0 EXECUTE ExportToSAP @UpdateRecords'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor.
Even stranger yet is is that this works just fine on our PI-DEV system. I created an identical communication channel connecting to the same database with the same UID and PWD and it won't work in PI-QAS.
Any help/ideas you could share would be greatly appreciated!!!
Thanks,
Chad

Hi Chad.
Normally, itu2019s a problem with your procedure. The Store Procedure is wrong and something is different between your DEV environment and QAS environment.
Try to ask to DB team check it.

Bruno

JDBC- RFC - JDBC How to send result set to rfc ?

Hi Friends ,
 I am working on scenario like .
 I have to read data from a sql server using select statement and send same data to r3 ( using RFC we are inserting the same as a copy ) .
 Then i have have get confirmation from R3 as data inserted succesfully - Flag .Then we have to come back to same table and update one field flag as 'U'.
 For this I am using JDBC Sender Adapter and RFC Receiver Adapter .Will i use as Synchronous Interface ?
 I think i have to use JDBC Receiver Adapter also to Complete the cycle .
 Can you please clarify the following....
 1. how is that whole selected data will send to R3 . If i use Select statement in JDBC Sender Adapter it will as resultset .It will contain Multiple Rows right ? Our RFC Will accept the parameter as string .
 2. If we use the synchronous Interface will it send row by row from the result send Then get back the result from R3 and come back again to JDBC ( Database ) and update the required field ?
 3. In JDBC Sender Adapter , the Update Parameter doing the Updation Part prior to get the status from R3. How to handle this ?
 4. Do i need to configur teh separate JDBC Receiver adpater for this updation part ? Then We cann't use Synchronous Interface right ?
 5 . Will JDCB Sender Adapter get the result set (by select statement ) and send to r3 as row by row and get the confirmation message as inserted ?
Best Regards .,
V.Rangarajan

Hi Udo ,
 Thanks for your reply . If i have used the synchronnous RFC Calls , that RFC will return the flag as 'Y' or 'N' , for Either succesfully inserted or Not successful .
 In this synchronous how can i use the JDBC Receiver adapter ?
 If 'Y' or 'N' I have to update the same table ,same row which have sent to RFC . My doubt , we are wrirtng the SQL select query as " select * from table name where UpdateStatus is null " .
 So it will return multiple rows right ? I have to uses the synchronous response form RFC to update the row of the same table using JDBC Adapter right ?
 Can you please explain me little bit more ? I am new to xi .
Best Regards .,

Gor The result set is closed after switch to latest microsoft JDBC driver

The same code works fine with the previous version of the microsoft JDBC driver, but throws
com.microsoft.sqlserver.jdbc.SQLServerException: The result set is closed.
for the JDBC driver 4.
Please Help!
Thanks.

I found the same exception when dealing with ResultSetMetaData.
Using the old driver (1.2.2828.100) it was possible to do something like:
Statement s = con.createStatement();
ResultSet r = s.executeQuery("select * from <table>");
ResultSetMetaData m = r.getMetaData();
r.close();
s.close();
int numCols = m.getColumnCount();
But using the new driver (2.0.1803.100) it complains that the result set is closed.
The solution was to keep the ResultSet and Statement open until after the ResultSetMetaData is no longer needed. It is somewhat inconvenient because before it was possible to have a utility method that would return a ResultSetMetaData object and not have to worry about keeping the Statement and ResultSet objects around.
I was hoping for a speed increase for batch inserts by having the latest driver, sadly there is no performance gain.

SCROLL_SENSITIVE result set can't see the data inserted.

hi all ,
I am trying to display all the latest data available in the table through SCROLL_SENSITIVE and UPDATABLE result set after inserting a new record in the table.

Sure - but you could have answered your own question if you had read the doc link I gave you in your other thread and next time you post code use \ tags on the lines before and after the code - see the FAQ for info

Problem in Retrive values from result set

I have a class where i do all database operation .First i fire select query and take values from result set and based on that value i fire update query.
Problem is that i am not getting all values from result set . i get only last value and when i fire update query i get error as :Resultset is closed.
I am using acess and java.

You probably are using the same Statement object for both queries? Try creating separate Statement objects for each query. (My guess is this a problem with the way you're using JDBC, not a Servlet issue.)
