Any function that can get me occurance of a particular char in a string?

Hi All,
I want to calulate occurance of a semi colon in the following string , so i can achieve this using connect by but I am looking to use a function(preferably an oracle built in function)
string : ';1;2;3;4;5;6;7;8;9;'
Regards
Rahul

Yet another »classic« approach:
SQL> with t as ( select ';1;2;3;4;5;6;7;8;9;' str from dual)
-- actual query:
select str
,      nvl(length(translate(str, ';'||str, ';')),0) number_of_occurances
from   t
STR                 NUMBER_OF_OCCURANCES
;1;2;3;4;5;6;7;8;9;                   10
1 row selected.Edited by: MichaelS on Nov 18, 2010 3:13 PM

Any app that can play wmv files?

Hi, like some other users here, I'm facing the inability to open my wmv attachments in my mail -which is quite frustrating considering that most of my friends are windows users. I know iPad doesn't support wmv and some other windows video files, but isn't there any app that can get around this problem? I searched Appstore and one of the results I got was called AirvideoFree but dumb 'ol me can't understand how it works. Their website doesn't help much either. Any answer (in simple to follow steps) is welcome. If this app is not what I'm looking for-is there any other available?

I contacted Omar with support for Azul and was quickly answered. I was having the same problem. Since iOS4 multitasks you will need to double click the home button to show apps running in the back ground. Hold down on the app until it wiggles. At that point x out or close Azul. Now go back to your mail and click on the attachment and you get option to open with Azul and by using that it will open and play the .wmv file.
Omar said problem is a bug and they are working to fix it in an upcoming update. This is a great little app and the price is very reasonable IMHO. The above mentioned work around involves a couple of extra clicks but since I could not even view .wmv before I am happy with the work around.

SSAS- DAX expression : Is there any DAX function that can return multiple values ?

Hi,
Iam in search of a DAX function that can return multiple values as result. please find below scenario where i want to implement the same.
I have three Tables: Table A (typeid, Cost, Qty ) ,Table B (typeid, Cost, Qty ) , Table C ( typeid,Typename ) .
Table A                                       Table B
Table C
type id cost Qty             type id   Cost    Qty
typeid typename
1          100    100                3         300
300                  1           aa
2           200    200                4          400
400                  2           bb
                                                                                         3           cc

i have to club cost and Qty of two tables(four measures) as two measures in the UI report. There are more columns in these tables that restrict the UNION of the tables.(for the sake
of understanding , i have not mentioned the othr columns). In the UI report(Execl 2013-power pivot) iam plotting these measures against the
Table C.Typeid. Hence the measures drill down against each
Table C. Typeid as shown below:
Typeid Table A.cost Table A.Qty TableB.cost TableB.Qty
1              100             100
2              200             200
3
300             300
4
400             400
My requirement is to club these measures so that the report will be as below
Type id cost   Qty
1          100    100
2          200    200
3         300     300
4        400      400
Since i cannot club these in model,as a work around, i created a calculated measure in excel(Analyze tab->Calculations->olap tools->calculated measure) with the condition as below:
new cost = IIF (ISEMPTY(TableA.cost)="TRUE",TableB.cost,TableA.cost)
new Qty = IIF(ISEMPTY(TableA.Qty)="TRUE",TableB.Qty,TableA.Qty) and dragged these new measures into the report. It was working fine as expected.
But this functionality of Creating calculatedmeasure in excel report is possible only in 2013 excel version.
Now the requirement is to get the same result in 2010 excel. Can you please help me in implementing the same in 2010 excel? or any other alternative method to bring the columns in model itself. I tried to create a measure in table A with DAX expression as
: new cost :=CALCULATE(SUM(Table B.cost),ISBLANK(TableA.cost)) -> but this will return only 1 result .i need Sum(Table A.cost) also if it is not blank.
Thanks in advance

You can use SUMX ( 'Table A', 'Table A'[Cost] + 'Table B'[cost] )
However, if you install the latest version of Power Pivot in Excel 2010, it supports the ISEMPTY function, too.

If your phone is offline, the ONLY way to find it is to look for it the old fashioned way. Your phone CANNOT be located electronically if it's offline.

After upgrading to OS Mavericks, I realized that the Partition for Windows is gone. I have really important data on this drive without a back up. Is there any way I can get this data before reformatting. Is there any third party software for receiving the data or any possible way? Money is not a limitation to this fix. Please help!!!

sure pretty simple. make a backup of your current settings
http://support.apple.com/kb/HT1766?viewlocale=en_US
then restore device from old backup you need pics off of
then import pics to computer
http://support.apple.com/kb/HT4083
you may need to save pics to camera roll first
then restore the new backup and sync pics back to phone via itunes

I have bought the Lightroom 5 disk last december but I mistakenly misplaced the case that had the serial number on it. I need that number to download it otherwise, the disk is no use. Is there any way I can get someone where else?

Change your iTunes (Apple ID) password along with any other password that was stored in the iPod. If any passwords are associated with credit cards, contact the CC company and get your card replaced (with a new number). If any passwords are associated with your bank or any savings institution, contact them also and discuss approprate action with them.
The "Find my..." function is pretty much useless if the device is in the hands of a thief. All that is necessary is for the thief to connect to any computer with iTunes and "Restore as new."
The only real protection you have is with the personal information on the device rather than the physical device itself. Something as small as an iPod should have a strong 8-digit (or longer) password AND be configured for automatic wipe in the event of ten consecutive incorrect password entries.

My itunes was deleted off of my computer. Is there any way I can get my music from my Ipod back onto my computer?

Most of my music is from CDs that I don't have anymore. I've got over a thousand songs and most of them were deleted when my computer crashed. Is there any way I can get my music from my ipod back onto my computer? Any sort of program you can buy? Thanks for any help, I really appreciate it!

I guess the problem come from me or I really need those contacts before he calls me for it. I'll try some method that I got from some responders on your support website. Do you have or can you recommand any software that can solve this problem?

One more thing. I just update my iphone that my boss gave to me but it seems to be like it giving me some trouble. My iphone was updated not too long and was successful. I try to lock into it and it telling me emergency call. I plug it to my itune and it telling me that the sim card is not valid or supported. So I inserted my sim card that I usually use to call and it still saying the same. Please help me get into it.

And as far as paying for phone support, here are a few tips:
If you call your carrier first and then they route you to Apple, you usually don't have to pay for phone support.
If you are talking to Apple and they ask you to pay a support fee, ask if you can get an exception this time. That usually works once, but they keep track of the times you've been granted such an exception.
If you still end up paying the support fee, that fee only applies if it's not a hardware related issue. In other words, if it can be fixed by just talking over the phone and following Apple's instructions, then the fee applies. But if your device is deemed to have a hardware failure that caused the issue, then the fee should not apply, and you can ask for it to be waived after the fact.
This forum is free, and almost all of the technical support articles the Apple tech advisors use are available on this website. Literally 99% of what they can do over the phone is just walking you through the publicly available support articles. In other words, you're paying the fee to have them do your research for you. It's like hiring a research consultant to go look stuff up in the public library so you don't have to. You're capable of doing it; you'd just rather pay someone to do it for you.
It's like Starbucks. You know how to make coffee. Everyone knows how to make coffee. And Starbucks coffee isn't any better than what you could make at home for far less. But you want the convenience. So you're really paying a convenience fee. Milk is more expensive at 7-Eleven than it is at the grocery store... because it's a convenience store.

While synching iPhone, box popped up and said changes will be made to my contacts. If I didnt allow change, it wasnt going to continue to sync. Now half of my contacts are gone and I have all of my wifes contacts. Any way I can get mine back?

While synching my iPhone, a box popped up and said that so many of my contacts are going to change. That happened before and my contacts and my wifes contacts ended up in each others phones. So we just had to go through and delete the ones we didnt want. When I did it this time, half of my contacts are gone and I have all of my wifes. Any way I can get my contacts back?

You should have been sycning them with your computer all along. Sync them from your computer back to the iphone.

I tried mackeeper to recover files but it could not. Any other way any one has tried to recover a system library folder after OS upgrade?

No, it doesn't store a clone. You would have needed to make one with either SuperDuper or CarbonCopy Cloner.
If the files were in your ~/Library folder then they may still be there. As I said, you can access it by
going to your Finder "Go" menu hold the option key to choose "Library". I wouldn't think an upgrade would overwrite anything in ~/Library.
If you have a Time Machine backup you may also be able to use that to retrieve them.
