JDBC ResultSet and direct D/B access are returning different no. of rows

I am testing a JDBC application, which is using a DataSource definition configured in Visual Admin under JDBC Connector node.
This program gets the JDBC Connection via lookup thro' JNDIContext.
What is interesting is I am getting different no. of rows from ResultSet compared to direct execution in the Query Analyser.
SELECT DISTINCT IC.ship_to_num, IC.policy_type, IC.exp_date, IC.insurance_cert_id
FROM site_user SU
INNER JOIN user_bill_to UB ON SU.user_id = UB.user_id
INNER JOIN insurance_cert IC ON UB.ship_to_num = IC.ship_to_num
WHERE (DATEDIFF(dd, GETDATE(), IC.exp_date) <= 14)
AND (DATEDIFF(dd, GETDATE(), IC.exp_date) > 5)
AND IC.breaking_14_day_alert_date IS NULL
AND (SU.customer_id = 'dealer') AND (SU.is_owner = '1')
(3 in Qu.Analyser Vs. 0 from JDBC)
Or
SELECT * FROM message_target
(405 in Qu.Analyser Vs. 380 from JDBC)
I compared the JDBC program code results Vs. "DB Initialisation" tab result in Visual Admin tool Vs. Direct 'Query Analyser' of SQL Server results.
The programmatic JDBC results are equal to "DB Initialisation" tab results !
What is wrong here ?
Any help is greately appreciated.
Thanks,

Hi Prasad,
I have never experienced this problem, but after taking a quick look at the javadoc for some JDBC classes, I found something that may help.
Try looking into the <i>setMaxRows</i> method on the <i>Statement</i> class. The URL below will take you to the complete javadoc for this class, however, here is the part that I believe relates to your problem:
"...If the limit is exceeded, the excess rows are silently dropped."
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Statement.html
If you are not setting this limit explicitly in your code, the JDBC driver implementation may be using some default value.
Setting this value to zero means that there is no limit, so you may want to try that.
Kind regards,
Mike

JDBC-ResultSet and ArrayList

Hi guys,
I need a help. The situation is next: I�m trying to store some results of ResultSet into ArrayList. Unfortunately, when I�m retrieving the data from ArrayList, the result, which I�m getting, is only the last row of a table. The result is repeating as many times as ArrayList size is. Could somebody explain me why it happens?
There is a snippet of the code to get a data from the ResultSet and add it into ArrayList:
// Execute a query
String sql = "select * from user";
          Statement stmt = conn.createStatement();
          ResultSet rs = stmt.executeQuery(sql);
          ArrayList list = new ArrayList();
          // Extract data from the result set
          while(rs.next()) {
CustomerBean cb = new CustomerBean();
               if(rs.getString("first_name")!=null)cb.setFirstName(rs.getString("first_name"));
               if(rs.getString("last_name")!=null)cb.setLastName(rs.getString("last_name"));
               if(rs.getDate("dob")!=null)cb.setDob(rs.getDate("dob"));
               list.add(cb);
Another snippet of the code to retrieve the data from ArrayList:
for (int i = 0; i < cb.getUserData().size(); i++){
System.out.println("First -"+((CustomerBean)cb.getUserData().get(i)).getFirstName()); // hire an error
System.out.println("Last - "+((CustomerBean) cb.getUserData().get(i)).getLastName());// hire an error
System.out.println("Dob - "+((CustomerBean) cb.getUserData().get(i)).getDob());// hire an error
Thank you in advance

One thing you should change is the multiple calls on the same column to retrieve the columns value from your results set. This can definately be problematic depending on the JDBC driver you're using.
I might suggest something like this:
// Execute a query
String sql = "select * from user";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
ArrayList list = new ArrayList();
// Extract data from the result set
while(rs.next()) {
CustomerBean cb = new CustomerBean();
String firstName = rs.getString( "first_name" );
String lastName = rs.getString( "first_name" );
Date dateOfBirth = rs.getDate( "dob" );
if ( firstName != null )
   cb.setFirstName( firstName );
if ( lastName != null )
   cb.setLastName( lastName );
if ( dateOfBirth != null )
   cb.setDob( dateOfBirth );
list.add( sb );
for (int i = 0; i < list.size(); i++){
System.out.println("First -"+((CustomerBean)list.get(i)).getFirstName()); // hire an error
System.out.println("Last - "+((CustomerBean)list.get(i)).getLastName());// hire an error
System.out.println("Dob - "+((CustomerBean)list.get(i)).getDob());// hire an error
}Although this might not immediately solve your problem, it might help narrow down the area where the problem might exist.

Using objects rather than jdbc resultset to fill reports

Hi buddies!
I�m developing a small sample of application that generates reports using values retrieved from objects.
The idea is simple, I have an arraylist of objects and want to fill my report which these objects atributes.
Jasper Project API has a class called JasperFillManager which is used to fill reports and takes 3 arguments, for instance:
JasperFillManager.fillReport(JasperReport reporttofill,HashMap parameters, JRDataSource dataSource)
I�ve created a custom JRDataSource named fonteDadosJasperCustomizada
This class implements an arraylist of objects and two methods from the interface JRDataSource which are responsible for giving the values to fill the report. This class doesn�t take values from a resultset! ;)
but for some reason nothing appears to me after executing the application... everything is alright I think the might be a mistake in the interface methods, the report also is alright.
All sugestions are welcome
thanks

Wait events 'direct path write' and 'direct path read'

Hi,
We have a query which is taking more that 2 min. It's a 9.2.0.7 database. We took the trace/tkprof of the query,and identified that there are so manay 'direct path write' and 'direct path read' wait events in the trace file.
WAIT #3: nam='direct path write' ela= 5 p1=201 p2=70710 p3=15
WAIT #3: nam='direct path read' ela= 170 p1=201 p2=71719 p3=15
In the above, "p1=201" is a file_id, but we could not find any data file, temp file, control file with that id# 201.
Can you please let us know what's "p1=201" here, how to identify the file which is causing the issue.
Thanks
Sravan

What does:
show parameter db_filesreturn? My guess, is that it returns 200.
The direct file read and direct file write events are reads and writes to TEMP tablespace. In those wait events, the file# is reported as db_files+temp file id. So, 201 means temp file #1.
Now, as to your actual performance problem.
Without seeing the SQL and the corresponding execution plan, it's impossible to be sure. However, the most common causes of temp writes are sort operations and group by operations.
If you decide to post your SQL and execution plan, please be sure to make it readable by formatting it. Information on how to do so can be found here.
Hope that helps,
-Mark

Disable Mouse and other Keys except Number and Directional keys in a screen

Hi all,
Recently we have developed a sceen program as per the requirements of client who are used to enter meter readings using only Enter key. They used to give Enter key to give meter readings, date of meter reading, meter reading note and consumption in their legacy system.
Though we developed the screen as per the requirements with all validations checking simultaneously which are required but we failed to handle mouse and other keys as we have not found any specific events occured by the keys.
Now some of the meter readers are using mouse and other keys and because of this our code is getting failed and no validations are working at all. So we want to disable the mouse and other keys except Number keys and Directional Keys while we are in the screen so that they are bound to work with the Enter and NumKeys as per their requirements.
Please help me with an idea or code snippet by which we can solve the problem. <removed by moderator>

Difference between copying cube content using datamarts and direct copying

Hi Experts,
I have been going through the SDN for the last 6 months and this is my first post
I know two methods of copying the cube content from one cube to another.
One is data mart method in which we create a datasource based on the cube and
then create a transformation between the new cube and datasource.
This method is used if our source cube is in same server or in diff server.
Other method is directly copying the cube content from source to destination
by creating a transformation between two cubes .
this is used if source cube anddestc u be are in same server.
My doubt is if both the cubes are in same server then what is diff between first method
and second method,
Please clarify me

Hi,
Now Iam closing this thread with a conclusion .
The question is what is the difference between copying cube
content using datamarts and direct copying
Also what are there any other methods to copy cube contents
from one cube to another.
The diff bet using data marts and direct copying is
In case of datamarts,ven if the source cube is changed in futute there is no effect on the target cube.
In case of copying directly,whenever the source cube is changed,the transformation becomes inactive.
so we have to activate the transformation again.
ALso there are some other methods to copy cube contents fron one to other .
But datamarts is sap standard one.
Thankyo every one for giving answers

Sundar

Hi anji,
Good answer,
GAP ANALYSIS:
The gap analysis is the analysis on what the differences between actual system are and what the customer want to develop.
A through gap analysis will identify the gaps between how the business operates ad its needs against what the package can can't do. For each gap there will be one of three outcomes which must be recorded and auctioned, GAP must be closed and customized software can be developed close the gap, GAP must be closed but software cannot be written therefore a workaround is required, GAP does not need to be closed.
In simple terms: Gap means small cracks. In SAP world. In information technology, gap analysis is the study of the differences between two different information systems or applications( ex; existing system or legacy system with Client and new is SAP), often for the purpose of determining how to get from one state to a new state. A gap is sometimes spoken of as "the space between where we are and where we want to be." Gap analysis is undertaken as a means of bridging that space.
Actual gap analysis is time consuming and it plays vital role in blue print stage.
While implementing the SAP to one company they use ASAP Methodologies to implement it has 5 steps .
1: project preparation .
2: Business blue Print .
3: Realization .
4: Final preparation .
5: Golive .
in Business blue print they give AS IS and TOBE that means what are the different requirements are to be made to reach the customer requirement that is called Gap analysys

Difference between Realtime Data Acqisition and Direct Data Access ?

Hi experts,
What is RDA and DDA and whrere these two are used ?
What is the Difference between Realtime Data Acqisition and Direct Data Access?
Please explain me in a detail manner, i will assign points for ur valuable answers..............

Hi,
Eventhough the aim of the two methods are to report on the latest data, there is a difference in both.
In Realtime Data Acqisition you are loading the data into BW and then reporting on that data from BW Infoproviders.
http://help.sap.com/saphelp_nw04s/helpdata/en/52/777e403566c65de10000000a155106/content.htm
I think you are refering to Virtual providers by the term Direct Data Access. In Direct Data Access you are not loading data into BW. Data is residing in R/3 itself. Your reports will fetch data from R/3 directly. The data is called during execution of a query in the source system.

How to I contact Apple about a support issue with Game Center--itself, directly. I changed my Apple ID and now I cannot access my game center account that I had previously. It created a new one for me with my new apple ID instead of keeping the old one.

I want to submit an issue with Game Center--itself, directly. I had an account set up that I used to play online games. I changed my appleID and then I no longer could access my game center account. I, apparently, had a new game center account created for me (which is friends with my old account) and now I cannot access my original game center account.
If I can't get access to email apple directly (which seems ridiculously difficult to do), then someone please tell me how to FIX the issue.
Thank you

Yes. I have tried that. When I use the ID I had before, it sets it up as a new account and I don't want to lose my stats attached to my old account.
Let's say that my old nickname was "user10" and I used the email, "[email protected]" for my apple id. I changed my apple id to "[email protected]" and it changed my game center account to "mynew" and somehow I am friends with my old acct, "user10". I tried getting a password reset for "user10" but I apparently don't know my own birthday, which is possible because I usually give a false one, but the same false one each time.

To sync photos from a Mac or Windows PC to your device using photo applications
Make sure you have the latest version of iTunes installed.
In iTunes, select your device's icon in the Devices list on the left.
Click the Photos tab.
Choose "Sync photos from."
On a Mac, choose iPhoto or Aperture from the pop-up menu.
On a Windows PC, choose Photoshop Album or Photoshop Elements from the pop-up menu.
Note: Some versions of Photoshop Album and Photoshop Elements don't support collections. You can still use them to sync all your photos.
If you want to sync all your photos, enable the option for "All photos, albums, events, and faces." If you want to sync photos from only some albums, events, or faces, enable the option for "Selected albums, events, and faces" and then select the albums you want. If syncing on a Mac with iPhoto version 6.0.6 or later, you may enable the option to "Include videos" to sync videos directly from iPhoto to your device. (Requires iOS 3.0 or later).
Click Apply.
To sync photos from a folder on your hard disk to your device
Drag the images you want into a folder on your computer. If you want images to appear in separate photo albums on your device, create folders inside the main folder and drag images into the new folders.
In iTunes, select the device icon in the Devices list on the left.
Choose "Sync photos from."
Select Choose Folder from the pop-up menu and choose your main image folder.
Click Apply.

I have a 4s and I am not sure when it began, but I cannot save photos that are nit camera related in my photo roll. Furthermore, applications that I have downloaded and should request access are not apparent in my privacy photo settings. What should I do?

My problem began when I wanted to change my screen saver. At first, I would try to take pictures and download images and they would toatally disappear. So then I uninstalled my icloud, deactivated my photostream, and supposedly restored my phone to the last back up. Well atleast now the pictures that I take are not dissappearing into thin air. However, I have never been able to and I still cant seem to turn on the request for photo applications in my privacy settings. I am not sure when this initial problem began. As of now, I am not able to save downloaded photos to my camera roll and applications that request access to my photos are not displayed in my privacy settings to even accept the request. This is very frustrating and I am not sure what to do.
I have tried everything from disabling and enabling my icloud, disabling and enabling my photo stream, stopping the photo app and restarting it, and even restoring it to the last itunes backup.

This works!
go to settings> general>restrictions>privacy and allow changes. Make sure that your camera is on under allow!

Windows network setup: can't share on network and have each system access internet directly

Windows network setup would not let me set up my network so that I could both:see my other computers on the network and have them both connect directly to the internet. It wanted to set one up as a server.
Is it dangerous to arrange it that way?
If not, several people have told me it should be no problem to set up my network so that my computers can see each other and share, and yet still ahve access to the internet. I think this is enabled through DHCP?
Would someone mind lending me a hand?
I have a BEFW11S4v2
