How many column can I make in a table or view??

What is the maximum column that I can create in a table or a view in Oracle9i??
When I create a view of 500 columns, I encountered an error "too many sort key", can any one tell me what is the limit for Oracle9i on number of column

I believe the limit was raised to 1000 columns in 8i; that's certainly what it is in 9i. At a guess I would suspect your problem is the number of columns in your GROUP BY or ORDER BY clause. It would be helpful if you posted the error number, the ORA-nnnnn bit.
Cheers, APC

Adjusting forecast by considering how many pieces can i make in Hr in DP

Hi Gurus,
After monthly planning is done at consensus adjustment level user wanted to consider even how much a product can make TON/Hr before adjusting consensus forecast.I am worried where and how i can bring this requirement for further adjustements.
Please it will be really great if anyone can respond me.
Thaks & Regards,

Hi Raj,
Please try any one of the ways to get your requirement
1) Using the past history key figure data, extract data from BW
for production done/Hr by selecting the relevant key figures
2) Try running transactions /sapapo/ppl1, /SAPAPO/CDPS_REPT

How many columns can be display if use Class cl_gui_alv_grid?

Hi,
    I have a fieldcat table which contains 200 items. But it only shows about 90 columns in my alv display.
I use function: LVC_FIELDCATALOG_MERGE to build fieldcatory and I found there are 200 records in my fieldcatory internal table when I debug it.
    Can anyone give me some advise to show full culomns in my alv display?
    Thanks a lot~

Hi,
In Debug mode check check the NO_OUT field for each entry in the Field Catalog. If it has the value X for some fields then those fields will not be displayed.
Or check is there any Layout Variant is passed to the IS_VARIANT parameter.

How many transfers can I make from imported CDs to blank CD, external hard drive, via my Mac?

Hi! I was curious, because I heard from a friend that if we wanted to transfer a song on our computer we had ripped from an audio imported CD to a blank disc, or external hard drive, there was a certain number of times we could transfer that particular song or transfer that CD, before iTunes would no longer allow us to transfer it anymore. Is this accurate? Is iTunes equipped to only be allowed to transfer iTunes Store content to blank discs or other non-Apple devices, as opposed to non-iTunes Store content (i.e. songs from audio CDs that were imported into the Mac)?
If it is accurate that there is a limited number of transfers that can be done via iTunes with non-iTunes store content, is there a way around this? Possibly install another music program that allows unlimited transfers to blank discs and external hard drives, i.e. Windows Media Player?
Thank you for your time.

There is no limit for CDs you have RIP'd.
For iTunes purchases with DRM, you are limited to burning a specific playlist 7 times to an audio CD.
And the link posted above is three years old and irrelevant at this time.
Just don't "share" (illegally transfer) files with others.

At max how many columns is advisable to create in a table/view

Hi All,
I have two transaction table from which i want to create a simple view or materialized view. But the number of columns is about 200. So i want to know at max how many columns is advisable from the performance point of view.
Even though i will create 200 columns in a view , for a perticular client installation i may not use all the columns.
one more thing i will never use 200 columns in the select statement . At a time i will use only 4/5 columns.
It may happen from this four column one column will be the 1st and 2nd column will be the 200th one.
I want to know how it affects the performance and in which scenario . Please help if any body knows or already faced this kind of scenario.
I am using oracle 10g .

thanks for ur reply .
We are going to use this view in a report , so if i will create it as simple view it will affect report performance. because the view script is too long ...so every time quring to a view will decrease the performance.
Are you asking me if it will? I think it probably won't but of course you have the means to test it to be sure, right?
As u said MV should be done with minimum possible column . what can be the maximum column in MV ..??It would be defined by the limits on:
* The maximum number of columns that a table can contain
* The size of the query needed to define the select statement
* Limitations on queries needed to maintain the data

I'm a school tech coordinator. Many computers and many iPads. How many Apple IDs can I have per device, and how many devices can have the same Apple ID? To make my life easier, I'd like 200 devices to all use the same Apple ID.

I'm a school tech coordinator. I have many computers and many iPads. I apologize if there is a some place that has all the rules governing the use of Apple IDs. I looked, and I even tried to get the answers from multiple Apple rep's. I couldn't find the answers.
How many Apple IDs can I have per device?
I want to use the same computer to sync and backup many iOS devices. The iOS devices would be associated with different Apple IDs.
I may load apps under a school Apple ID and have users load their own apps under thier own ID.
How many devices can have the same Apple ID?
Can I use the same Apple ID on all the computers in a lab?
Can I use the same Apple ID on all iPads for a particular grade level?
Are the rules different for iOS devices and computers?
I know that there are limits on "authorize" and "de-authorize" and how frequently those things can be done.
Recently I heard that for the life of an iOS device, it can only be associated with five Apple IDs. That is not good for a school giving iPads to students in a 1:1
To make my life easier, I'd like 200 devices to all use the same Apple ID.

How many tasks can I have in NI-DAQmx system?

I am working out of the office this week - please send your response to [email protected] as well as my normal email [email protected].
I am designing a new test platform that will run on C# (because we like object oriented text based programming and because the IDE is free). For hardware we'll use your PXI modules (because your hardware is ultra-reliable). I'm starting with the following PXI modules 6259, 4072, 6509, 2575, and 2569, but we made add other modules later as future requirements demand. I am doing the system software architecture now. I've done some dabbling with Ni_daqmx, and I loathe "tasks" and "channels", but am determined to make them work.
The difficulty I'm having revolves around the overhead with setting up tasks and channels and with the concept of tasks and channels. Help hasn't helped much. Tasks seem to work great if you intend to always collect the same large amount of data from many sources and always will do it in exactly the same way.
We want something much more akin to random access memory. We'll have UUTs of different kinds coming on and off at random times. Sometimes a test will need a simple DC voltage, and other times another test will need 2 seconds worth of data at 1MS/s. It can cost around 150msec to make that change (stop the current task, creat another one, configure anohter channel, start up a new task, blah, blah, task this, channle that - for the life of me I can't understand what this damn taks concept does for me but make matters more complicated and bog down my system).
I can just barely glean from the help that I can have only one analog input task at once, but I can have sevferal taks of several different kinds running at the same time ( a digital output task and another task for digital input, and another task for analong input, etc.) . It does seem that I can set realys without having to put them into a channel and a task (Thank goodness for that - I just wanna turn on a relay I have no idea what a relay "channel" might be.)
In the PXI system I described above I'll have two devices that are analog input devices, the DMM and the Daq. Even with two devices, can I only have one analog input task running? Does that mean I've got to waste 150msec just to switch from the DMM to the Daq? (Do you understand my frustration with "tasks"? - I should be able to say "read DMM" and turn around and say "read Daq channel 0" without having to jump thru task and channle hoops and waste a bunch of time doing it).
I'll also have Daq digital IO and two 6509 digital io modules. Do I have to cram all of that into some "task" concept too? The Daq card has got many other kinds of wonderful capability (frequency measurement, counters, analog output). How many tasks can I have for that stuff? On the DMM card I can measure capacitance amoung other things. Will I have a capacitance task? The idea of a "capacitance task" hurts my head.
Golly I hate tasks. Please help.
I am working out of the office this week - please send your response to [email protected] as well as my normal email [email protected].

Dave,
Thanks for posting to the NI Forums.
For the good of the community we like to keep conversations that start of the forums on the forums rather than moving to email. If you want to move to email support I recommend contacting NI through the email route.
I will answer your questions here. If you need more direct contact please feel free to contact us through [email protected].
For some the concept of tasks may seem daunting, however, for many applications it makes life a lot more simple. A task at a very fundamental level is simply a collection of channels with a single type (AI, DI, DO, etc.) and a single timing configuration (sampling rate, continuous vs. finite, etc.). It is a way to organize configuration data.
The concept of a task is an abstraction like OO programming. Like OO programming it may take some time to understand but can be a time saver in the end. Also like OO programming it does add some initial programming overhead. It is much more simple to simply type a printf statement in C than to have to create a bunch of classes just to output text to the screen. You can accomplish the same thing not using OO programming, but in the end OO programming is extremely useful, because it groups useful information and methods together in one place.
With very simple applications OO programming sometimes does not make sense. But as a program gets more and more complex OO programming becomes more and more useful. It takes some learning but it is worth it.
I believe the concept of a task does the same thing. It does not change the actual functionality of the device or add excessive overhead. It is just an abstraction that pulls configuration data about a specific "task" and methods the task can perform into a single logical place.
Unlike the entirely abstract concept of an Object, a Task is run on a physical device and therefore has physical limitations. You can create multiple tasks of the same type, but you can only run a one timed task of each type on a single board at a time. In other words you can have multiple AI tasks running at the same time but they need to run on different boards or only one can be timed (have a rate). You can also have multiple timed AI tasks configured for a single board but only one can actually be running at a time.
The reason you can only have a single timed task running at a time is because the M-Series boards (and many other boards as well) have a single timing engine for each type of acquisition or generation. There is a single timing engine for AI, one for AO, and so forth. You cannot have channel 1 running at 1 MS/s and another running at 50 kS/s.
However, tasks can exist even when they are not being actively run. You can create all the tasks you need at the beginning of your program and simply start and stop them as you need. After the task is stopped you do not need to clear the task until the end of your program. You can further increase performance by moving the Task into the latest state possible without actually starting the task. This can be done by calling myTask.Control(TaskAction.Action). The Task states are further explained in the NI-DAQmx Help Manual.
The concept of a task will need to be used with any device that is being programmed using NI-DAQmx. The 6259 and 6509 will need to be programmed using DAQmx. With the 2575 and 2569 you have the choice of either using the NI-DAQmx API or the NI-SWITCH API. The SWITCH API does not use the concept of tasks. For the 4072 you will need to use the NI-DMM API. This API also does not use the concept of tasks.
Hopefully this information is helpful. Let me know if you have any additional questions or concerns.

How many times can I reinstall CS4 if I inactivate it?

Hello
How many times can I reinstall CS4 if I inactivate it before I make a new installation on the same computer?
Regards
Mikael

Mikael,
Not really, because it made me go to slipstreamed installations that proved even better. It takes some time to make a slipstream, but in the end it proves even better IMO. When Win7 comes out, one of my first steps will be to make a slipstreamed version and post a guide here on how to make one tuned to your needs. This is a very old screenshot, way outdated, but it shows what a slipstream installation can do for you:
Just insert the DVD and have some coffee. When you have finished your coffee and the PC has finished it's installation, you are ready to roll/edit. All tweaks will have been performed, logon scripts executed, etcetera.

HT1977 How many times can you download an app?

I have purchased an app from itunes store, my family has alot of devices and i want that app on all of them. we upgrade alot so how many times can you upload an app? Unlimited?

Welcome to Apple Support Communities
You can download an application in all the devices with your Apple ID as many times as you want for free. You may have to pay again for it if the developer releases an update and wants to make it paid.
It's recommended to have the same Apple ID in all your family devices, but you can also use it with a different Apple ID. In that case, you will have to let your family know your Apple ID password to update the application

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

If recovery mode does not work try DFU mode.

To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:

Hi kundan,
You can create any number of variables for an infoobject but you can use only any one in a query.
Your requirement can be achieved as below.
Create a selection variable of type 'Multiple Single Values' on 0Calday.
Drag 0CALDAY to the column in the query designer. Drag you key figure below 0CALDAY. It will be placed in a new structure.
Hope this helps.
