How can I make this update, when I have two records (a primary key, no seq)
How can I make this update in pl\sql
Below is the table with data
CREATE TABLE INSERT_TE ( PIDM VARCHAR2(8), FORM_ID VARCHAR2(2), TEACHER VARCHAR2(30) )
commit;INSERT into INSERT_TE ( PIDM, FORM_ID, TEACHER ) SELECT '1106651', 'TE', 'Teacher, Alber Howard' from dual

For your table, you can set a single like this:
PIDM column + a sequence. (new heading):ALTER TABLE INSERT_TE ADD(TEACH_SEQ NUMBER) / UPDATE INSERT_TE x SET TEACH_SEQ = (SELECT n FROM (SELECT ROWID rid, ROW_NUMBER() OVER(PARTITION BY pidm ORDER BY TEACHER) n FROM INSERT_TE t) s WHERE s.rid = x.ROWID) PIDM FORM_ID TEACHER TEACH_SEQ 1106651 TE Teacher, Alber Howard 1 1106651 TE Teacher, Alber2 2 2321241 TE Teacher, Silly Billy 1

The first record should update the table when the condition is sarchkl_admr_code = "REC1" and the second record with the condition is sarchkl_admr_code = "REC2.
>not normally.
but you can do (now)
select PIDM, FORM_ID, TEACHER, 'REC'||TEACH_SEQ TEACH_SEQ from INSERT_TE PIDM FORM_ID TEACHER TEACH_SEQ 1106651 TE Teacher, Alber Howard REC1 1106651 TE Teacher, Alber2 REC2 2321241 TE Teacher, Silly Billy REC1
and use the last column to update you...

How can I fix my resolution when it will automatically from high to low?
Since I installed my touchsmart 610-1180qd I had problems with passing automatically to 640 x 480 resolution. When I try to change the resolution in the Control Panel, the resolution button is not highlighted. I have to turn on my computer works to return to the initial setting high resolution. I called technical support 4 - 5 times all ready without solution. I'll give them another call, but if anyone knows what is the problem, I would appreciate your help.
I also have the same problem with the resolution of the screen change after the mode 'sleep'. After being unable to find a solution to the problem on the internet, I have played around with my settings and have found what seems to be a viable solution (at least for me). I say this because I know that the issue is not yet resolved, but at least I found a way to keep my video resolution even after the return of the mode 'sleep'. I have tested my 'solution' for the week past and have found that it works... until now. So without further ADO, here is what I did:
(This process which requires you to write your settings of resolution in a two steps)
First of all, you need to open the 'NVIDIA control panel '. This can be done by right-clicking on a any part of the homepage and selecting "NVIDIA control panel", or will the taskbar (next to the clock) and right click on the NVIDIA icon. Once you are in the Control Panel, select "Change resolution" under the heading "display". When everything is working properly, you will see your "recommended" setting, as well as all the other parameters available. Then click on the 'Customize' button which will open a pop-up window. In this window, click on the button 'Create Custom Resolution'. This will bring up a context menu that allows to display all of your current settings (for example Horizontal pixels, vertical lines etc.). There are 17 variables, you will need to register. Once you have entered these parameters, you can put your computer in mode 'sleep' to activate the resolution problem. For me, I had to wait some time before the issue of the resolution would surface (an indication that the problem occurred before even to see the screen was a sound the computer would just before you wake.) It's the sound that makes Windows when you connect a usb device and windows detects it).
Now that your screen resolution has changed (a very undesirable occurrence), you must make your way to the NVIDIA Control Panel. It is extremely difficult due to the large size of the windows and such (I had to hide my taskbar automatically in order to access all the necessary buttons). You will need to then press the button 'Customize' and 'create a custom resolution' button once more. Once there, you can enter your 'custom' variables, even if they are the real '' recommended '' for your resolution settings. (Tip: under the "calendar" section, you may need to move from "automatic" to "manual" in order to access the lower set of variables.) Once you have finished, click on the 'test' button, and your resolution should be back to normal. I think he will ask you if you want to preserve settings, and if they are to your satisfaction, then click Yes. Once you have done this, it will save your settings 'customized', so that when your computer becomes crazy and changing your resolution again, it will be pushed to change for your custom configuration.
Some things to note, you can't create and save a custom setting when your computer is not working properly because it will just tell you that it is a double parameter. Your can only create and save the custom setting when the computer has been removed and all parameters available in addition to 640 x 480. That's why you go through all the trouble in resolution 640 x 480. That's what I did to make my computer 'Act' normal after the mode 'sleep'. It has worked for me so far, but I know that the problem is still there because all the other resolutions are missing (next to 640 x 480 and my "custom" of the 1920 x 1080 resolution). Of course once you restart your computer, all your choices of resolution will be back.
If this does not work for you, I'm sorry. I'm not an it expert by any means. I couldn't stand having to restart my computer whenever he entered mode 'sleep'. I am very disappointed that hp has not addressed this issue or have found a real solution to it, but at least I can leave my computer goes into sleep mode now. I tried to be as detailed as possible in my explainantion of measures to take, but feel free to ask if you have any questions. I'll try to clarify if I can, but as I said, I'm no computer expert, and I could not be able to answer your actual technical questions.
Good luck to you all.

Before the upgrade, I was able to duplicate a standard file and rename it to that I work with the client. I then will mark the file and send it to the customer when I got access to the internet. This simple procedure is available with the upgrade WITHOUT internet access or cloud? I have no access when working with clients. Help!
Hello
What is the version of the OS you are using? Unfortunately, you will not be able to rename them, duplicate or delete files from Adobe Acrobat DC app. You will need to do the same to a third-party to do the same file manager. However, you don't need internet access or registration to DC to do the same thing.
Thank you

When I have an an effect in the Gallery of effects, for example, a picture of a cloud, the race changes too. How can I stop the blow of change? I have Cs3/Cs2. If it has something to do with the appearance Panel, I don't see a background or stroke attribute when I click on the cloud. Only when I deselect.
You must select the fill only in the appearance Panel. Stupid, but it's like that.

I have dell computer and I would like to delete everything on it, except that which came with my computer when I bought it please tell me how to do a factory default thank you
Hi Amy.
There are two ways to go about this.
Firstly, if your computer has a recovery partition or if it came with the recovery disk, it can be restored to settings by default and aid programs. Note that this procedure will probably remove also your personal files. You will need to back up your personal files beforehand.
Second method is to simply go to add/remove programs and uninstall the software until the software only left is that that came pre-installed on the computer.
Please tell me the number of full model of your computer.

Hello
I have an application that I'm migrates from the web to mobile, and I recently encountered a problem where it will crash on the charge, but _ONLY_ when they are packed for liberation as well as iOS.
FOR EXAMPLE:
1. for Android, works at
-Emulator
-USB debugging
-release mode compilation
2. for iOS, works in:
-Emulator
-fast compilation USB debugging
-USB debugging standard compilation
Doesn't work in:
-compile ad hoc
Initially, I thought it was because of loading SWF with ActionScript, but even after replacing these files with static JPEG, it always crashes.
I commented all the traces, after another report by the forum that has listed the tracks as a problem with ad-hoc compile.
I tried mobile bundle strings resources out of the sight of problem that these channels are not displayed in the view of problem (but do it somewhere else).
In all cases, the result is the same:
Discover loads then freezes before he gets far enough set navigatorContent property (declared in MXML) so it hangs just with no. visible labels.
Have you tried a number of things to debug it and twenty minutes by compilation, there is a limit to how much I _can_ try, so, please, please, someone has an idea of where to look the potential problems that could be causing my application to fail?
Thank you
Gaius
I have it.
I used the Swiz (which is awesome, btw) framework and compilation of the library of Swiz rather that to use the CFC that I needed a change to the base, I forgot one of the metadata tags since the compiler args - for some reason, recovered by operating in any other mode of compilation, it crashed when running in release mode.

Hi guys,.
If all goes well, a super simple question to someone... Driving me crazy right now! I have a folder on my desk of RAW (image) files, that I imported into LR up and worked. So now when I open LR and access this folder, the images are seen behind a grey colour and cannot be selected and / or worked on. Only way around it so far has been rename images, re-import them to LR and then expand them, which is of course very time consuming. How can I access these images and expand them?
Thank you much in advance!
