First execution of query is always best than all the following
I have a static query that I execute in sql*plus in the same machine as the database and all the time, the first execution is faster than the following executions and it driving me crazy! Any help is appreciated...
The database is Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
The query has a comment in the there so I can change the query to be "different" form the previous ones.
I ran it in sql*plus with set autotrace traceonly and timing on and the results are:
First execution:

Greetings,
I hope this email finds you well. I bought my iPhone on December 1st, 2012 with a track order W459517623. When I first bought it, it was meant to use all the services provided by Great Apple including the new LTE service as a main service for such device. Now I just realize that such service does not match with the model I have, as per this link:
http://www.apple.com/iphone/LTE/
Model A1429
(GSM model)
Saudi Arabia - Mobily
The model Apple sent is A1428
I believe that such service should be provided to my devices too. Also, Apple always find best ways to solve such queries.
Please advise me
Thank you and Regards,
AbdulrahmanI'm assuming you bought it via the Apple Online store. Contact them. Use the Contact Us link at the bottom of the page. Did you buy the phone from the store in the country you intend to USE the iPhone? If you bought the phone in the US store and intend to use it OUTSIDE the US, you only have yourself to blame, as they shipped the CORRECT phone for use in the US.

Since i got my iPhone 4S, Last year. it's the 8gb experminetal version. My phone's volume always appears. All the time. And since i got the iOS 8 yesterday. It got even worse, it won't get out anymore. I'm super mad. I don't know what's going on. Is it my case? But, i don't use a case anymore. It doesn't even lessen. And when i take pictures for like 10 seconds, i get like 50 photos. Without even clicking the button. This is a real problem for me Apple, and i need you to do something about it. I need an answer real soon.
I got Troubles too with iphone 4s with the new iOS 8, its unstable, apple said its for that model to but its not totally true, well few troubles disappear if you do this:
First you need to Sync your iphone like regular you do it, but check you could made a Saffety and restore back up manually in your computer.
then when this it's already done, disconnect your iphone, then restore your iphone as factory settings, beware! don't do this if you don't have your Saffety copy first!
when you restore your iphone as factory settings iTunes will ask you if this is a new phone or a previous phone, well, select previous iphone and select the back up copy you made, and let iTunes restore all, that fix a few issues in my phone, but the real problem its iOS 8 its not good for 4s. -

SELECT * FROM DUAL;
The above table STUDENT_DETAILS stores the details of all the students and each student has a unique student id.
Another table PAYMENT_HEADER saves the payment details as a document for each month which has a header id.
In the PAYMENT_DETAILS table, payment details are stored for the students (who made the payment for that month). This table does not save the data for a student if he has not paid on that month. This table is connected to the PAYMENT_HEADER table through a header Id.
The view should be such that when I pass the document number, it shall show the names of all the students, but shall show payment amount only for those students who had paid under the selected document number, for other it should show null.
I tried the following query:
select * from (
select sd.student_name,sd.DOB,sd.sex,sd.contact_number,pd.doc_num,pd.month_name,pd.cum_amount
from hr.student_details sd left join
(select hdr.doc_num,hdr.month_name,det.student_id,det.cum_amount
from hr.payment_header hdr, hr.payment_details det
where hdr.pay_header_id = det.header_id) pd on sd.student_id = pd.student_id)
But when I pass the filtering values like document number, it does not show some students with null values.
select * from (
select sd.student_name,sd.DOB,sd.sex,sd.contact_number,pd.doc_num,pd.month_name,pd.cum_amount
from hr.student_details sd left join
(select hdr.doc_num,hdr.month_name,det.student_id,det.cum_amount
from hr.payment_header hdr, hr.payment_details det
where hdr.pay_header_id = det.header_id) pd on sd.student_id = pd.student_id)
where doc_num = 1 or doc_num is null;
My requirement is that, every time I use a document number in the where clause for the view it should show the paid amount against the student names who has paid on that month and for all other student it should null. Total student number is 13. So every time it should show 13 students only even when I pass document No 2 or 3.
Seeking your help.

HawkerHi Frank,
as per your advice, I am omitting the 'DOB', 'GENDER','ACTIVE','CONTACT_NUMBER' fields from the 'STUDENT_DETAILS' table.
I shall create separate tables and insert the desired output from the view for each where clause.
First let us create three tables each for the desired out put:
1) For the desired output I want to see when I pass doc_num as 1
create table HR.SDT_PAY_DET_DOC_ONE (
STUDENT_ID NUMBER(10),
STUDENT_NAME VARCHAR2(50),
DOC_NUM NUMBER(5),
C_AMOUNT NUMBER(10),
primary key(STUDENT_ID)
2) For the desired output I want to see when I pass doc_num as 2
create table HR.SDT_PAY_DET_DOC_TWO (
STUDENT_ID NUMBER(10),
STUDENT_NAME VARCHAR2(50),
DOC_NUM NUMBER(5),
C_AMOUNT NUMBER(10),
primary key(STUDENT_ID)
3) For the desired output I want to see when I pass doc_num as 3
create table HR.SDT_PAY_DET_DOC_THREE (
STUDENT_ID NUMBER(10),
STUDENT_NAME VARCHAR2(50),
DOC_NUM NUMBER(5),
C_AMOUNT NUMBER(10),
primary key(STUDENT_ID)
Now I shall insert values in each of the above three tables:
INSERT ALL

I recently built a computer and was installing Windows 7 Ultimate 64 bit on it. I have a few problems going on. First of all all my browser are constantly crashing (including IE, Firefox and Google Chrome) on random reasons. I checked the conflicts on chrome
and there were none conflicting with it. I did the /sparrow thing to clear and fix corruption but that did not work. I've tried making a new user file in Chrome, same results. Another problem I've been having is that my SSD disk that I have Windows installed
on shows way to much space being used in My Computer. I checked all the file sizes within it and it is a maximum of 40GB all put togather but My Computer says only 28GB is free of 111GB SSD drive.
Here are the specs to my computer:
AMD FX 8350 CPU
Mushkin 16GB 1866hz RAM
Gigabyte Radeon R9 270x 4GB VRAM GPU
Gigabyte 990FXA-UD5 motherboard
600W Amrageddon PSU
120GB Mushkin Chronos Deluxe SSD
2TB SSHD Seagate
Anyone know what I can do?
P.S Drive cleanup freed only 500MB and the Recycle Bin is empty
P.P.S I moved the Program files from the SSD to the SSHD (If that matters) Also the download folder.HH
1-You can check what is using the space with a free 3rd party tool called Treesize from Jam software
2-I believe you have a hardware issue and here is why.
Event viewer logs show
1-The platform firmware has corrupted memory (see snip)
2-The Browser are crashing because of something called a memory exception (Cx05) see snip
I would check for a BIOS update, configure your system to generate a user mode DMP file and upload it when they crash. Beyond that there are only a few events in EV (~300). We can alwasy use more.
You can configure Windows to create user-mode dumps. Create a System Restore Point first.
Copy and paste the following in Notepad and save as a .reg file, then right-click the .reg file and select "Merge" to add to the registry, a .dmp file should be created in the C:\CrashDumps folder:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\explorer.exe]
"DumpFolder"=hex(2):43,00,3a,00,5c,00,43,00,72,00,61,00,73,00,68,00,44,00,75,\
00,6d,00,70,00,73,00,00,00
"DumpCount"=dword:00000010
"DumpType"=dword:00000001
"CustomDumpFlags"=dword:00000000
After the app crashes, can you then upload the dmp file via Windows Live Onedrive or other file sharing site.
The following link has information on using Windows Live Onedrive:

IMovie won't import from iPhoto (this is different than all the other post)
Before you think, "Oh... this is the typical 'iMovie 7 isn't importing iPhoto movies' question" this isn't. I've looked through a ton of threads and questions trying to find something similar to this.
Q: I have all my digital camera (Canon SD500 camera (not camcorder), no known compatibility issues with Apple) movies, which are in .AVI format, in iPhoto. iMovie is being weird as in it will only import SOME of my camera movies. For some events, it imports ALL the movies in. For some events, it won't import ANY of the movies in. For some events, it will only import SOME of the movies included in it.
If someone responds, "Your camera is incompatible" OR "the file format isn't supported" they should have points deducted from their account because they didn't read anything except for the first sentence and decided I don't know what I'm talking about.
Here's some interesting things that have happened:
1) I found ONE event in question called "Wedding Pictures & Movies" that wasn't showing up in iMovie. The camera we took movies with has other movies in other events that have successfully been imported into iMovie. But anyway, I realized that for some programming languages (I don't know if this is true with iMovie, I doubt it) that the ampersand (&) sign is used in code and shouldn't be used in titling things. So I shortened the name down to "Wedding" and all the sudden (more like after iMovie asked me if I wanted to create the thumbnails for the movies), SOME of my movies were put into iMovie, not all.
2) Upon realizing that either: the event name was too long OR the & sign actually did screw it up, I shortened another event in question from "Reception Pictures & Videos" to simply "Reception". Upon opening iMovie, it never asked to build the thumbnail library with movies from this "Reception" event that I did the exact same thing to as the "Wedding" event.
3) I thought I would try and force iMovie to refresh the thumbnail database (or build thumbnails for another movie again) by taking another movie with said camera above, the same one that I've taken all the other movies with, and imported the movie into iPhoto. Upon opening iMovie, it asked me to build the thumbnail, but only did so for the movie that I just took.
What could be going on that movies from the same camera aren't showing up in iMovie? I can understand other cameras, but these movies are all from the same camera. Some will show up while others will not? Does anyone have a clue what could be going on here?
BTW, the movies have not been edited in any way. They are all still in the exact same format and everything since they were imported into iPhoto.Before you think, "Oh... this is the typical 'iMovie 7 isn't importing iPhoto movies' question" this isn't.

Is there a query or program to find all the unreferenced images or assets?
I am looking for a query or a simple program to find all the unreferneced images or assets within DAM. This will help us clean out the images that are no longer required.

Why needs the first reference much more time to close than all others?
Hi all,
I am facing a strange problem with closing an array of references.
A few words to my environment:
I can load dynamically VIs into a subpanel sitting on my main VI but if I unload and reload Visa I need to close my Visa properly, not just by stopping.
Therefore I wrote a closingVI which is attached. In this VI I look for a "Stop" button and send a true by signaling.
The problem now is that the very first reference in the "Control[]" needs around 40seconds to close, all following refs just need <1ms! By the way, the array size is just about 24 and it is independent which ref comes first.
In addition to that the problem just occurs when the VI runs longer than 10 minutes, which doesn't makes any sense to me.
Do you have any suggestions?
Stay Hungry, Stay Foolish

I don't know what you are referring to here. You are closing all of the Control references in a single node. Are you saying it takes that long for the Close Reference for the entire array?
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

A warm welcome to Apple discussions!
A 2003 iMac cannot support Snow Leopard 10.6; you'd need an Intel processor and that cannot be retrofitted to your Mac. What does "About this Mac" in your Apple menu say for your processor speed? What does it say about how much RAM you have?
If the processor is 1ghz or faster, you can run OS 10.5; otherwise, you are maxed out at 10.4.11.
Also, are you running any commercial ("pay for") anti-virus or security software? They are notorious for slowing most Macs to a fraction of their speed potential.
A too-full hard drive can drag down performance, especially if you don't have a lot of physical RAM installed. If you single-click your hard drive icon and then do command i, you'll see the disk usage. Looks like this:
The value for "Used" should be no more than about 90 percent of "Capacity." In the example image, that drive has about 34 percent of its space used and 66 percent free--more than enough. Please post what you see for your Capacity and Used numbers
There are a few more things we might check but this is a good start.

Hi,
I noticed once of my Fact tables in my Power Pivot model contains a blank record. I can't understand why.
So I added a Filter expression to the underlying Power Query query, something like; -
Text.Length("MyField") > 0
However after refreshing the Power Query query which contains the above expression the blank record still appears within my Power Pivot table.
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/hi..
As my understand, the blank record in Power Query will be return null value . So that, You try to use Text.Length("MyField" ) <> null.

New 17 Macbook Pro 5 key is brighter than all the others
Why? Why? Why? I do alot of work in low light and this key is like a homing beacon. My OCD kicks in and this key drives me nuts. I went back to the Apple store where I purchased this and checked the other display models. The same issue, BUT only with the 17's not the 15's or 13's. The 15's look perfect as they should.
What happened. I've never had this issue with my other macbook's. What changed on the 17?
Can this be fixed or do I need to switch to the 15 or just deal with it.I just bought a used MBP 17 and its 5 key was much brighter than the others. I popped off the 5 key, trimmed a small piece of paper from the recycle bin, dabbed it with a black marker, and laid it into the top left corner of the hole where there was an obviously brighter zone of light shining from below. Replaced the key, now its just about the same as its neighbors and the physical keystroke isn't affected by the presence of the paper sliver.

Imovies - how do I seperate the videos from the photos. My library has bundled them all together from iphoto
One way I was able to do this, was to make a Smart Album in iPhoto, with the rule of showing just the movie files. This will work, once you know what format the movie files are in.
In iPhoto, select one of your movies, and right click it. Look for the option: "Reveal in Finder" or "Show in Finder" (this depends on the version of iPhoto).
Once you see the file, look for the three letters AFTER the period. Like this:
.mov (QuickTime movie)
.avi (Uncompressed Windows Video)
.mpg (MPEG video)
Back in iPhoto, when you make your Smart Album, set it up like this:
Once you have it set like this, press RETURN (or click "Ok").
What you'll see is all the videos that have that file extension (.mov, .avi, .mpg, etc.) listed. Now the nice thing is this: Every new movie you add to iPhoto will automatically get listed here, regardless of where in iPhoto they live!
Integration with iMovie:
By making this album in iPhoto, when you get to iMovie, you'll be able to see the movies when you select your Videos Smart Album.
I hope this helps you out. They have iPhoto and iMovie workshops at Apple Stores that cover this too. They're free, and you can learn a lot.
Sincerely,

I want to upgrade but want to know that I will be getting many of the features that I am expecting to. As of right now, running Snow Leopard, I only have 2 finger scrolling via trackpad.
