How to use the case and decode to extract data

Hello gurus of PL/SQL,.

I use Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64-bit Production version

I have a table in the following form-

drop table TT2;
create table TT2(College, Class,gender,status,fees) as select
'IITB','MBA','M','P',255600 from dual union all select
'IITK','MTech','M','P',300000 from dual union all select

certain conditions of extraction are as follows-

College of 'IITC' and status = 'P'-'good SouthRegion '.
College 'IITD' and 'IITK' and status = 'P' and type = 'F' - 'female NothRegion spent.
College not in 'IITK' and status = 'F' - 'Ex Kanpur Failed'

Need help to understand how to use the SDK for our use case

Hi all!
I'm having a lot of problems with understanding the SDK and how to work with it.
The documentation available only is generated comments PHP which summarizes the methods, variables, about classes and groups.
It is a reference that helps a little more on the technical aspect of the classes and their relationship with each other, but it IS NOT tell me, for example of one of the sample files:
echo "-ch. |" -netmoref < netmoref > [choose] Vim portgroup MoRef. Required to create. \n » ;
It's the example script that creates an external network, what I have to do to set up a new client, organization.
Another unknown is what is a "fence Mode" in the present: $config-> setFenceMode ($fenceMode);
Another concept of basis of the SDK I could not really grasp yet - is why some of the classes start as VMware_VCloud_API * while others are VMware_VCloud_SDK *.
Another example? in the scree of new organization of the GUI, in terms of policy, there is a section 'Limits' - I searched carefully and found no corresponding SDK/API method in the documentation!
Also, I couldn't find a way to delete organization (when a customer cancels a subscription, for example).
I apologize if my attitude invades a bit on the angry side, but I was home for a while now and every time I get more irritated watching the "documentation" try to understand something
Nevertheless, Kimberly Wang code is simply remarkable and very well written, just help to know how to make this huge puzzel I wish (even in the sample code that I do not understand how to find the right order of things in nesting objects in order to do something like object of class VMware_VCloud_API_OrgSettingsType for the parameters for example then feed him in a VMware_VCloud_API_AdminOrgType (as well as other parameters - why are they not in the $settings object? And finally another object of VMware_VCloud_SDK_Admin is to truly create the Organization!
Why the VMware_VCloud_API_AdminOrgType couldn't be the class doing the creation of the Organization)?
This is a brief summary of the things I'm trying to understand.
Perhaps, I missed some sort of guide for this? and if not, I would be very grateful if someone could explain in a few words to help me to understand this puzzel so that I can start doing my work and build something out of these awesome (even if cryptic) building blocks!
Thank you

Sorry, you must use

$SDKAdminOrgObj = $service-> createSDKObj ($adminOrgRef);

It should return you a... Object SDK_AdminOrg.

How to optimize the performance of this query SQL

Hello
I need to find the age for each day, but I need for all previous dates in a single query. So I used the following query:
Select trunc (sysdate) - level + 1 DATE
trunc (sysdate) - level + 1 - created_date AGE
elements
connect by trunc (sysdate) - level + 1 - created_date > 0
I get output (FOR the DATE and AGE) that is fine and correct:
DATE AGE
--------- ----------
6 JULY 15 22
5 JULY 15 21
4 JULY 15 20
3 JULY 15 19
2 JULY 15 18
JULY 1, 15 17
JUNE 30, 15 16
JUNE 29, 15 15
JUNE 28, 15 14
JUNE 27, 15 13
JUNE 26, 15 12
25 JUNE 15 11
24 JUNE 15 10
Now I need to calculate the average age for each day and I added the average in the following query:
Select trunc (sysdate) - level + 1 DATE .
AVG (trunc (sysdate) - level + 1 - created_date) AVERAGE_AGE
elements
connect by trunc (sysdate) - level + 1 - created_date > 0
Group of trunc (sysdate) - level + 1

This query is correct? When I add the aggregate (avg) function to this query, it takes 1 hour to retrieve the data. When I remove the average request function that gives the result in 2 seconds? What is the solution to calculate the average without affecting performance? Help, please

How to use the GPU for the AMD over-pants D500 in Mac pro 2013

I install the first CC 2015 Pro and After Effect CC 2015 to 2013 with the graphics card AMD over-pants D500 Pro Mac, I can set GPU rendering in Premiere Pro, but impossible to define in the After Effect, only can use the CPU in the preview of the setting, how can I do?

AE uses only a few NVIDIA CUDA enabled cards to speed up rendering drawn with RADIUS. This feature never quite worked, with disabilities masks and effects on layers 3D, and NVIDIA has changed the direction of their development of this technology for the Ray-traced rendering feature is is more developed by Adobe. They are working on another technology to use the GPU, but it is not yet available. There is nothing you can do to enable the GPU acceleration, unless you have a compatible NVIDIA card.

How to set the font for this SuperNova will display the text properly

I have a problem with the use of Firefox with Supernova. Supernova is a program for the Visual disabled allowing you to enlarge the office. When you visit the page

http://www.raadvanstate.nl/Uitspraken/zoeken-in-Uitspraken/Tekst-uitspraak.html?ID=73735 & summary_only =

you will see orange colored text in the main text block. It appears correctly. However when I enlarge the screen with Supernova this orange text is barely readable due to the fact that the letters seems constructed points instead of a smooth line.

Note that this happens even with this page where I enter these details of the issues. Supernove enlarged rhe screen, texts outside of the text box are horrible while the text in this text box is good.

I ask this question here because when I use Internet explore this problem does not occur.

I tried to make a screenshot, but the screenshot feature only "sees" the screen is enlarged. So when I zoom to 100% with Supernova, the text in the screenshot seems to agree.

I realize that this is a difficult question to reproduce, but any help is welcome. Note that it is not a real option for me to enlarge the font with the Firefox options. Supernova expands the full screen, not only the text on the Web page. In this way, I am also able to see the menu / bookmarks of Firefox itself.

Thank you very much
Hans

How to use the trigger for Hammer

Hello

I used a hammer and an accelerometer of pcb to do some tests of beam. I want to express signal for start of log data after I use the hammer hit something. Here is my configuration in express signal.

Trigger type: analog edge. Source of relaxation: the channel of the hammer
Slope: fall. Level: 0

However, once he began to run, it says "logging was stopped because an error occurred with a step in the project. If this error is due to a device buffer overflow, you can improve performance by disabling updates to screen using the "view > views of Signal update during the race" menu item. You can also change the way in which the signals are recorded by changing the Logging Options in the tools > Options dialog box. Disabling "Prepare the log for display data" will greatly improve performance. "I've changed everything, but it didn't work.

Should I use other types of trigger?
