Difference in results while using .CHILDREN and .ALLMEMBERS
Hi,
I have two almost similar MDX queries, in one I am using .CHILDREN and in other .ALLMEMBERS. First one returns no rows, the second one returns two. Please help me in understanding why!
Query 1
select
[Measures].[Claim As Of - Count] on 0,
[Accident Date].[Year].allmembers on 1
from [AW Cube]
where [Accident Date].[Year-Quarter-Month-Date].[Year].&[2010]
---NO rows
Query 2
select
[Measures].[Claim As Of - Count] on 0,
[Accident Date].[Year].children on 1
from [AW Cube]
where [Accident Date].[Year-Quarter-Month-Date].[Year].&[2010]
--2 rows
---- Claim As Of - Count
--All 637,350
--2010 637,350
TIA,
Sourav
EDIT: Some clarifications: AccidentDate is one of the Dimensions in my Cube [AW Cube]. Year is a natural hierarchy while [Year-Quarter-Month-Date] is an user defined hierarchy. [Year-Quarter-Month-Date] is created in the below way: Year-->Month--->Quarter--->Date.
So 'years' can be obtained by doing [Accident Date].[Year-Quarter-Month-Date].[Year].members and also [Accident Date].[Year].MEMBERS. Hope I am clear.
Well, got the answer myself.
Actually every ".CHILDREN" gets internally translated to ".CURRENTMEMBER.CHILDREN"
Now, [Accident Date].[Year].&[2010] is the corresponding value for the slicer on user defined hierarchy.
Here,
"[Accident Date].[Year].CHILDREN"
actually gets translated to
"[Accident Date].[Year].&[2010].CHILDREN"
which is basically an empty set. Hence, Voila! The empty result set!

From the day I bought it I realized the phone heats up after a little use. It gets really hot while using Wifi and downloading. Anyone else having these issues? What's the solution to this?
Your VGA is definitely corrupted and it is irreparable, so just make the HP to change your vga.
Also next time read my post on how to keep your laptop cool to avoid same issues again.
I assume your laptop was pretty hot during some time and that's the result you've got.
Make it easier for other people to find solutions, by marking my answer with 'Accept as Solution', if it solves your problem.

Difference between join conditions using NVL and not using NVL
Hi,
I have a join condition in one of the applications as follows.
NVL(RQ.out_mesg_id,0) = NVL(RS.out_mesg_id,0)How is it different without using NVL function. What is the internal execution difference.
RQ.out_mesg_id = RS.out_mesg_idWill there be any difference in Performance and also in the query output.

Regards,
PaboluI suppose that's a bit of a trick question (or could be).
If the column is allowed to be NULL, then your 2 queries are NOT equivalent, so comparing isn't useful since presumably you can only have one correct result :)
However, if RQ and RS (no idea what the table names are) are both defined as having a NOT NULL constraint on the column out_mesg_id (ignoring the possibility of column level masking possible with the use of VPD here) then the optimizer could do better if you rewrote the query without the use of NVL (this would of course depend on your tables, indexes, etc ... i am merely showing you that it COULD make a difference).

Comparison of number of bytes transferred over network while using HTTPService and RemoteObjects
If I have to transfer data(say records of 100 employees in a DB) from Server to Client, I could use HTTPService and fetch the data as an XML file and then convert it to ArrayCollection in the Client. Or use RemoteObject and transfer the data in binary. Lets ignore other methods(Web Services etc) of data transfer for the moment.
Now, for the same data, if I implement the application using HTTPService and RemoteObject, I notice that the number of bytes transferred over the network is less in case of HTTPService(XML) when compared to RemoteObject(AMF) which is a shock to me. My understanding is that AMF transfer should be more compact than XML. Ofcourse, once the data is available, RemoteObject result processing is noticeably faster than HTTPService result processing. My concern is why data transferred using AMF is larger than XML. As an example, you may refer to the samples provided in TourDeFlex. Refer to the following:
HTTPService:
Found in : Flex Data Access->HTTPService->BasicExample
Link: http://www.adobe.com/devnet-archive/flex/tourdeflex/web/#docIndex=0;illustIndex=0;sampleId =12700
Click on the 'Get Data' button to fetch the data.
Bytes transferred - 1050
RemoteObject:
Found in : Flex Data Access->RemoteObject->BasicJavaRemoting
Link: http://www.adobe.com/devnet-archive/flex/tourdeflex/web/#docIndex=0;illustIndex=0;sampleId =13300
Click on the 'Get Data' button to fetch the data.
Bytes transferred - 1440
This is a significant size difference. You may see the data transfer size by using developer tools like the HTTPFox Firefox extension.
Am I missing something here? Any help will be very much appreciated.
Thanks,
BaluThere is definitely problem with your tool or you looked at something else. Please check the attached snapshots of the session using charles capture tool. The response sizes are way bigger than what you mentioned but remoteobjects is almost half of httpservice for the complete transfer including request and response. Check below -

How can I erase images from the clipboard while using ink and slide or sketches and lines apps?
I've been having trouble with my clipboard while using my adobe ink. Is there any way I can erase the images saved on the clipboard, because have been trying and I can't find a way to do it, it seems like the only option is by turning the selection into favorites and then a trashcan icon appears, but even if I choose delete it will only be erased from the clipboard favorites while remaining on the clipboard.
I've thought erasing the sketches App, or deleting the project but I don't want to risk losing my work.
Thanks!I posed a similar question in the Draw forum and got this reply:
Re: How to clear the clipboard and empty drawings ?
In short: you can't erase those clippings, at least not currently. -
Error while using Enumeration and Vectors

if I seperate the For block out of While loop then im getting cannot resolve enum variable, bcoz its declared in while loop, I cannot declare it out side of while loop because I dont know the perfect size of the array and it will change dynamically.

Mac Mini 2011 crashing often while using Chrome and Firefox
I have a Mac Mini 2011. OS is Yosemite 10.10. Processor 2.3 Ghz Intel Core i5. 8GM RAM 1333 MHz DDR3. It crashes often especially while using Firefox or Chrome. Basically it just hangs showing the beach ball. Then we have to turn it off and on.
How should I debug the problem?
Note: Although recently I upgraded RAM from 4 to 8 GB, the crashes were happening before that activity.
RahulWhen it next crashes note the time. Then reboot and open the Console app (in Utilities folder). Look for suspicious log entries at the time of the problem and post them here

HP Prime crashes while using CAS and loses stored variables
As the title suggests I'm experiencing some problems while using CAS whit my new Prime (it arrived 3 days ago). While doing operations like scrolling up the screen and copying/pasting things, or simply defining new variables it happens that the prime crashes (sometimes it also restart itself) and loses all the variables I've stored.
The prime is running the latest FW (6030). I've also noticed that after the firmware upgrade the DataStreamer icon in the app library has became grey and an exclamation mark appears when I try to start it.
Any help or suggestion would be great.
Thank you in advnce,
M1cha3lI have only a little experience with Primes RPN.
It does seem that for user variable, you do need to first create them before storing anything to them. a ENTER OK creates user variable a and puts a 0 on stack 1:
123 ENTER, 'a' ENTER, Shift Sto> or 123_'a'_Shift Sto> ( _ = space key) store 123 in a and put 123 on stack 1:
Other more expert users may offer better advice. -
What is the difference in Webintelligence while using SAP BW or MS SQL Server
Hi Experts,
What is main difference in using SAP BW and MS SQL server in SAP BO while creating Reports using Web intelligence, Crystal reports. I want to know mostly on Report Level difference.Hi,
I Have not used Crystal with Ms SQL server but webI i can tell .
SAP BW is OLAP Layer .
M S SQL Server is Database .
You can Edit your Web Intelligence Query SQL Code in MS SQL Server .
Not in SAP BW .
Combined Query is Disable in SAP BW but it is available in SQL Server .
Performance wise SAP BW Query is better because it calculates every thing in SAP BW & gives us Required Out . -
Inconsitent result whil using pre queries
Hi
I have three queries, q1, q2 and q3 where q3 calls q2 and q2 calls q1. I have a formula used in q2 which restirct the display of records with a particular formula.
I have excuted the query q3 and I received the results where q3 called q2 and q2 called q1. But this output is not the same when I execute each query seperately.
Could you please help me if using a formula create problem in getting the correct data.
Thanks
DeepakHi ,
Check in any query (Q1 and Q2) you have variable default values, Filter values or any conditions individually.
For example:
I have Q3 which should should me the all employees who are under Business leader B1.
The Q3 gets the employees from Q2 .
but Q2 in my case fetches teh data employees who are in Costcenter CC.So few employees are reduced here.
Also The Q2 takes data from Q1 which brings CC who belongs to Region WEST. Again the employees will get reduced .
So check if teh condition like this is restricting teh output.
As the daat bringing from all teh under laying queries comes as teh AND condition between various selections used in them.
I am very sure you are getting the less number of records in final Q3 ,while you are expecting more data.
It will be very rare that you get teh data more then what u expected.
Checl the various AND conitions between teh reports.
The query definition of teh underlaying reports will be the main cause of teh creation of AND consitions.
Thanks

Query overall Result while using structures
Hi all,
I have 2 structures in my query, in both <b>rows and columns</b>. Now I want to display the total result for all the columns in my structure. How do I go about that?
I cant use cell definition as I used the cell definition on a couple of cells to calculate and all other columns have been derived normally thru selections and formulas.
Any insight or pointers would be appreciated and rewarded.

At time I go to Google or click on a link that sends me to Google but except for the word Google everything is in some other language, such as, Ελληνικά, Διαφήμιση.
Do you notice any pattern to this, for example, does it occur with certain sites or types of sites?
In case one of your extensions is involved, could you test the same action in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled ''(Flash and other plugins still run)''
In the dialog, click "Start in Safe Mode" (''not'' Reset)
Any difference?
