JDBC 8.1.6.0.1 Bug with grouping function

Hi,
I found a bug in the JDBC 8.1.6.0.1 driver, concerning the new grouping functionality of Oracle 8.1.6. Look at the following code fragment:
String cSelect = "SELECT DACO_VU_NAME AS DIM1, ' ' AS DIM2, TO_CHAR(DACO_VERKAUFSDATUM,'yyyymm') AS DIM_DATE, GROUPING(DACO_VU_NAME) AS DIM1GROUP, GROUPING(' ') AS DIM2GROUP, GROUPING(TO_CHAR(DACO_VERKAUFSDATUM,'yyyymm')) AS DIM_DATEGROUP, sum(DACO_BRUTTOBETRAG_TX) AS VALUE FROM DATENCONTAINER GROUP BY CUBE (DACO_VU_NAME, '-', TO_CHAR(DACO_VERKAUFSDATUM,'yyyymm') ) ORDER BY 1,2,3";
try {
System.out.println("SELECT: " + cSelect);
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(cSelect);
while (rset.next()) {
String cTest1 = rset.getString("DIM1");
String cTest2 = rset.getString("DIM2");
String cTest3 = rset.getString("DIM_DATE");
String cChar1 = rset.getString("DIM1GROUP");
String cChar2 = rset.getString("DIM2GROUP");
String cChar3 = rset.getString("DIM_DATEGROUP");
System.out.println(cTest1 + "\t" + cTest2 + "\t" + cTest3 + "\t" + cChar1 + "\t" + cChar2 + "\t" + cChar3);
}When I compile this with the mentioned JDBC version and run it with java 1.2.2 (JDeveloper 3.1), i get the following output:
Ahrend GmbH & Co. KG 200003 0 0 0
Ahrend GmbH & Co. KG 200003 1 0 0
Ahrend GmbH & Co. KG 200004 0 0 0
Ahrend GmbH & Co. KG 200004 1 0 0
Ahrend GmbH & Co. KG null 0 0 1
Ahrend GmbH & Co. KG null 1 0 1
null 200003 0 1 0
null 200003 1 1 0
null 200004 0 1 0
null 200004 1 1 0
null null 0 1 1
null null 1 1 1As you can see, the grouping columns are mixed up. In this example, everywhere a normal row shows a "null" value, a corresponding grouping row should show a "1", but as you can see, for the last 6 rows, the ones are not in the first, but in the second grouping row.
When I compile the example with the Oracle 8.1.5 JDBC driver, I get the following, correct, output:
Ahrend GmbH & Co. KG 200003 0 0 0
Ahrend GmbH & Co. KG 200004 0 0 0
Ahrend GmbH & Co. KG null 0 0 1
Ahrend GmbH & Co. KG 200003 0 1 0
Ahrend GmbH & Co. KG 200004 0 1 0
Ahrend GmbH & Co. KG null 0 1 1
null 200003 1 0 0
null 200004 1 0 0
null null 1 0 1
null 200003 1 1 0
null 200004 1 1 0
null null 1 1 1The special thing about this example is, that I use a constant row for grouping (row 2). If you use a normal database row, everything works fine with 8.1.6.0.1, but nevertheless, this should be a bug.
Any comments on this are highly appreciated, since I need the JDK 1.2 for the application and I didn't find a working Oracle 1.2 JDBC version.
Thanks,
Thorsten.

Patches can be obtained from an Oracle Support Services technical analyst.

Bug with min function applied to an attribute?

Does anyone know if there is a bug with the minimum function when it is applied to an attribute?
I have Accounts, Date, Sales Type and volume in my request.
I have applied min(Date) in the fx of the Date column.
My query is hitting the YAGO table even though non of the columns i am using is mapped onto a YAGO table.
As a test I've removed the min function frem the Date column and applied it to the Account column.
Again my query hits the YAGO table.
Does anyone know if it is a bug or can someone propose a workaround?
I am using OBIEE version 10.1.3.4.1090414.1922 on Windows XP.

Hi,
You can create a separate report and refer it into the column of main report by 'Filter based on results of another request'
This should resolve
Hope this helps

Shading pattern bug with stitching functions

I am using Acrobat Professional 7 for Windows, but I don't believe the situation has changed in Acrobat 9.
I have a simple hand-crafted pdf that is designed to test shading patterns with extend regions when used with stitching (Type 3) functions. These behave according to the spec in most cases, but there is a special case where they don't. I've included the job at the end of this message.
The special case is where a Bounds entry is identical to one of the Domain values. The spec doesn't say what should happen for this case, but I might expect either the end child function would be ignored, or that it is used but the appropriate colour would be evaluated using it and applied to the extend region.
What in fact happens, is that the extend regions have their colour derived from evaluating 0 or 1 through the end child functions. This is true regardless of whether the shading domain includes zero. But, these are used the wrong way round.
This might seem like a specialised case that would never appear in the field from real world application, but that is not the case. I have dozens of such jobs from customers displaying exactly this problem with varying workarounds by producers such as (Agfa Apogee Normalizer), (Acrobat Distiller 6.0 \(Windows\)), (Adobe PDF library 7.77), (Creo Normalizer JTP ver. 3.1.6), (Adobe PDF Library 8.0).
In more detail, the job has one radial shading pattern using a stitching function with 6 child functions. The first child function coincides with the function domain, as do the last two child functions. The domain of the shading is a subset of the stitching function, arranged so that the end child functions should never be evaluated.
I believe the whole of the shading should be a solid cyan because the domain is 0.3 to 0.7. Only one of the child functions covers this range which is solid cyan. Acrobat displays the inner extended region as black which can only be explained by pushing 1 through the first child function, and the outer extended region is yellow which can only be explained by pushing 0 through the final child function.
I believe Acrobat should be using the shading domain limits for the extend regions. Instead, it is using 0 and 1. But worse, the values are being used the wrong way round.
This is my hand-crafted job for testing shading patterns with Type 3 functions. The job is hand crafted, and I haven't gone to the trouble of setting the xref table or setting the stream lengths, but Acrobat does repair the file and it behaves the same as other, real-world, jobs

Philip, thankyou for offering to look at this.
I have attached 'FunctionType 3 boundary.pdf' which was the original file I attempted to post. The file 'AcrOut Domain 0_3-0_7.png' makes it clear what I am seeing in Acrobat. I would also like to augment my original post a little to point out incompatibilities between Acrobat and CPSI.
1. From my PoV, compatibility between Acrobat and CPSI is important, so I've also attached a file that contains equivalent PostScript. On my Ricoh Aficio with CPSI (3016.203) inside it, the job is rendered in solid cyan as I would expect given that the domain of the shading is restricted to [0.3 0.7].
2. If the jobs are changed to make the shading domain [0 1] instead of [0.3 0.7], Acrobat displays a green ring (expected), and the inner extend region is now red (expected). The outer extend region remains yellow.
CPSI renders the job almost the same as Acrobat, but the outer extend region is painted in cyan, not yellow. An Nth reading of the PDF and PS specs has revealed a subtle difference; there is one sentence in the stitching function section of the PDF spec not present in the PS spec, it is "If the last bound, Bounds(k−2) , is equal to Domain(1) , then x′ is defined to be Encode(2i)". I take this to mean the outer extends region may have different color in the PDF and PS versions by design.
3. If the pdf job is changed to make the shading domain [0.01 0.99], Acrobat displays the inner extend in black as before (unexpected), otherwise the same as 2).
To summarise:
1. There appears to be a bug in Acrobat whereby it ignores domain of the shading when painting the extend regions.
2. There is an incompatibility between Acrobat and CPSI in the outer extends region when the final Bounds entry is equal to the Domain value. This may be by design.

Is this a bug with grouping sets?

A Possible Bug With Grouped Objects

This is my problem:
1. I group a drawing or I create an object (movie clip, graphic, button...)
2. I double click the object/group on scene to edit.
3. I go in to the group.
4. I go back to the scene by double clicking somewhere empty.
5. And object is gone. It's invisible. I can only bring it back by clicking on something NOT GROUPED on scene, or by clicking the red line on the timeline.
Note: This problem seems to be not occuring when I go back to the scene via the blue arrow icon pointing left at the top or by clicking the scene name.
I use Flash CS5 on a Windows 7 PC.
A collegue of mine said that the same problem was also can be seen in Flash CS4.

I tried reproducing the issue with the same setting and was unsuccessful in doing so.
I think the issue could be because you might have nested symbols and you are not sure under which depth you are operating under.
The bread crump trail is essentially created for this sole purpose. This helps you in finding out what you are editing and in which depth you are editing.
Please find the screen shot.
Also search the internet for more articles on using the bread crumb trail.
Hope it resolved your problem!

The bug with JNI function RegisterNatives in Java 1.6

JDK 1.6 has problems with implementation of native methods in the class that loaded at runtime. I found it after making debug version of JVM.DLL.
I have JNI code that
- loads at runtime a new class with native methods;
- implements these methods with RegisterNatives();
- gets Field and Constructor IDs (at this time JVM cleans all finction pointers in Methods Table of the class);
- creates the object of this class and passes it to Java code for callbacks.
When Java calls my native methods I get the exception: "java.lang.UnsatisfiedLinkError", the naive method was not implemented.
I did workaround in my JNI code:
- load the class;
- get Field and Constructor IDs;
- implement methods with RegisterNatives();
- create the object of this class and pass it to Java code for callbacks.
This version of my code runs fine.

What I do with Java? I am developing
- .NET JNI SDK (like regular JNI SDK for C++) for
integration .NET and SUN/IBM Java codes,
- technology of integrating Java applications with
other programming platforms without knowledge of Java
Application sources,
- automation of JNI programming in C++ and .NET,
- tools for conversion AWT based applications to
SWING, etc.
Beside Java projects I develop projects with
Databases, OLAP, WEB in .NET, C++, VB6, etc.
That is why I have no much time to focus in SUN Java.Yes and I am busy too.
That had nothing to do with my post however.
I suggested that if your sole or primary critieria for langauge selection is whether the language forums have company representatives then you should choose .Net rather than java.
Myself the forum support is never even a minor factor in language selection.

Creating a query with group function and non group function

Could anyone help me with creating a query that contain single row function and multiple row function in Report6i.
what i want to do basically is to create a query that will display sum of certain columns according to a column in that table

You can either calculate a sum yourself, or let Reports do it for you.
1. select sum(column) from table where ....
This will just display the sum, not the records.
2. Make a query: select column from table where ...
Create a summary field. You can do it manually or with the report wizard.
That will create a report like this:
   Column
       10
       20
       15
   ======
Sum    45

FOR UPDATE with group functions

Hi,
Is it possible to have a select .. FOR UPDATE and in that select using group by and having count? If so, where should be placed the FOR UPDATE clause?
Thanks

Hi,
Update and FOR Update are different functinalities of Oracle.
Update as name suggest :- update Database records based on the condition we give.
For Update :- It donot update any Database records, it helps to lock set of columns. we generally use FOR Update in Select query.
Please refer below link for better understanding on FOR UPDATE function

Okay, i have 2 bugs with maverick. First, when I delete a file within a window, the files deletes but the preview doesn't delete until I close the window and reopen it. Second, I work on a network of computers and the search feature is now buggy... When I search for a file, A) it asks me if it's a name, or it wont produce anything, and B), its slower than in prior OS versions and in some instances I have to toggle to a different directory and go back to my original directory in the search: menu bar or the search wont produce anything... Very buggy.

It appears to me that network file access is buggy in Maverick.
In my case I have a USB Drive attached to airport extreme (new model) and when I open folders on that drive they all appear empty. If I right click and I select get info after a few minutes! I get a list of the content.
It makes impossible navigate a directory tree.

ICal bug with month view

I primarily use week view on iCal, but sometimes i switch to month view for a larger perspective. Often, i use month view to check for any leftover events from the previous month in case i forgot to delete one or two.
I just found a bug concerning this. If i click on "month" today, it'll take me to the month view for june 2011, and from there i can navigate forwards or backwards. However, may 2011 seems to have a bug. If i click on < from june, it does nothing; if i click again, it takes me to april 2011. Similarly, if i click on > from april it does nothing and if i click again it takes me to june.
It doesn't end there. The june/may thing happens only when the selected day (the one shaded light grey on the month and week views and bright blue on the little month tab on the left) is after 04 june. If a day from the first week of june (i have my weeks start on sunday) is selected, the < button does take me to may, but several events which i deleted a long time ago are showing up.
Now, i have an event set for today (04 june). Since the first four days of june are in the same week as the last three of may, the month view for may shows these four days, as any normal calendar app would.
If i use the month tab to the left to navigate, i can access may 2011 by selecting any day on that month. However, iCal's behaviour depends on which day was selected previously. If the previous day was in april 2011 or earlier, iCal will show the month of may completely empty, which is great because i have no leftover appointments from may; however, the box for 04 june is also empty, which it shouldn't be. If the previous day was in june 2011, it'll show may with a repeating event on every sunday except the first, which is completely absurd, since i have deleted this event (and why isn't it showing on the first sunday in may?); the box for 04 june, however, will correctly show the event i have set for this day. If the previous day was in july 2011 or later, it'll show may with the repeating event on all sundays (including the first one) and it won't show anything on the box for 04 june.
Obviously, there is a bug with may 2011.
In case it helps, i do have a repeating event set to all sundays until the end of existence, but i have deleted all the entries from may and previously, since they have obviously already happened. Also, i had many other repeating events set to happen on different weekdays; these are to repeat themselves weekly until about halfway through june, and they started on april or may (can't remember right now). Like the sunday one, i have deleted all the entries from may because they have already taken place. Strangely (and thankfully), none of these appear when i visit may from june or later, as does the sunday event.
Any help would be greatly appreciated. Or am i forever stuck with week view, which has so far proven to be bug-free?
(I did a search on Google and another on the Apple forums for this issue but could find nothing, so i decided to ask the question myself. I apologise if somebody has already asked this question and i just couldn't find it.)

Greetings,
I have a vague recollection of someone else with this issue but haven't experienced it myself nor encountered it recently.
Troubleshooting:
1.) First make an iCal backup: http://support.apple.com/kb/HT2966.
2.) Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical and / or "ical"
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
__NOTE: Removing these files will remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
Once the computer is back up and running open iCal and test.
Hope that helps!

Is this a bug with BoEdge3.1?

Can anyone help me on the issue which my customer is facing for BoEdge3.1
Concerning Error Message: You do not have enough Named User Licenses to make this user a named user. You have 55 Named User Licenses. (FWB 00013)
This is the error message she was receiving when trying to change an
existing user from Concurrent to Named under the Connection Type on the
Properties panel.
The current workaround was to delete the existing Concurrent user, then re-add the same user as Named.
She have been going through this process of deleting existing users, and then
re-adding them as Named and it was working okay. Then, it stopped
working and she started getting the same FWB 00013 error message again.
She was not able to create any Named users now. Basically, the workaround
worked for a while - then stopped working.
She currently has a total of 88 users. 21 of them are named. 67 of them
are Concurrent. She is licensed for 55 Named.
Once again, the system thinks she has 55 users marked as Named. But
there are only 21 marked as Named.
She did notice that as she was going through all of her existing list of
users, in alphabetical order, she was opening the Properties tab and
checking the Named/Concurrent status - as she got to the 55th user in the
list that is when she started getting the error message again.
Is this a bug with BoEdge3.1?
And I got an ADAPT01194692.
I am not sure that Is the ADAPT related to this issue.
Please help me its very critical.

BlueTooth bug with car

Since the 4.3 update there's a big bug with the bluetooth connection with the car system - it still exists after a factory reset:
I paired the phone and the car. But every time they connect, I get a message box if I want to grant access to my phone's messages. Even the "Allow always" option does not work and I get asked every time. Very annoying!!

Hello, I'm having the same issue after updating my Xperia SP to Android 4.3 (12.1.A.0.266). In my car (Mercedes Benz A-Class from 2013) there is a radio called "Audio 20 CD" built in. Every time when I want to get into my car, my smartphone wants a connection request for my messages (SMS).The option "Always Allow" does not work. The phone does not remember the next time. I tried several times a new pairing of phone and car radio and I cleared the cache of the bluetooth-share app and smart connect app, but this didn't solve the problem. Is there a fix available? With kind regardsThorsten
