What is the maximum number of columns allowed on a table?

What is the maximum number of columns that a table can have? I have a research team that wants to have 140,000 columns on one table and 2000 rows.
What would be the best way to input (SQL*Loader?) that data on this table and retrieve data from this table? The highest number of columns that I have implemented on a table was 500.
Any feedback would be greatly appreciated.
Thanks. ;-)

Holy cow 140,000 columns and 2000 rows!! I think you are going to have to tell someone to come up with a better design because that doesn't sound like a relational table. Besides, I found this in the Oracle 8.1.7 Reference Manual:
"The absolute maximum number of columns in a table is 1000. However, when you create an object table (or a relational table with columns of object, nested table, varray, or REF type), Oracle maps the columns of the user-defined types to relational columns, creating in effect "hidden columns" that count toward the 1000-column limit. For details on how Oracle calculates the total number of columns in such a table, please refer to Oracle8i Administrator's Guide."

  • What is the maximum number of columns that can be displayed by sqlplus?

    Hello,
    Questions:
    Is there a limit on what sqlplus can display?
    What is the maximum number of columns that can be displayed by sqlplus?
    I cannot find anything on this in my search. I checked the limits page:
    http://docs.oracle.com/cd/B19306_01/server.102/b14357/apa.htm#sthref3658
    http://docs.oracle.com/cd/E11882_01/server.112/e16604/apa.htm#i635278
    It does not specify any column limits; however, I'm thinking it is tied to LINESIZE which is system dependent.
    Please confirm if true.
    Thanks!

    Received answer directly from SQL*Plus Development:
    "sqlplus does not have a limit on the number of columns it displays."
    They created a table with more than 256 columns with data and had no problem retrieving the data.

    It appears I have plenty of free RAM 14 GB), however, in Activity Monitor I see this:
    com.apple.iLifeSlideshow.MEXPC32ExporterHelper (Not Responding).  It’s a plug in.  Could it be corrupted? I have never seen tis before.  Would a reinstall of iPhoto help?
    Do I need to boot in 32 bit mode?
    I will take your advice and try splitting then merge in iMovie.
    Will let you know how it goes.

  • What's the Maximum Number of Achievements allowed for an app?

    We are working on an app and have created 39 Achievements,  but Game Center only shows 35 available achievements for the app. Does this mean that we are only allowed 35?

    No, you should be able to create more achievements. Some games developed by larger developers such as Pocket God and Angry Birds have well over 50 possible achievements. If you continue to have trouble with this, you may want to visit the Developer site.

  • What is the maximum number of globals allowed in one global file?

    I remember there was a limit discussed in a LabVIEW class, but I can't remember it. But I know I exceeded the number on one project and VERY WEIRD things happened. Does anybody know this number?
    Thanks Much

    HI Tbob,
    You are going to earn the title of Global Enthusiast if you keep this up
    Race conditions are to Globals as Venerial deseas is to sex. If you want to avoid the former then abstain from the latter.
    Yes you can use globals.
    In fact, I ran a benchmark comparing how fast I can read a global booean vs the same coded as a LV2 global. The Global booean was 6 (or was it 16?) times as fast.
    When answering Q's that use phrases like "strange things" we bring up the race condition and point users to LV2's.
    Sure text based programmers learn how to handle global access in multi-threaded environments. These types of interaction are implemented by making the global a protected section that are protected using semaphores. This same approach can be used to protect LV globals. Just ensure all reads and writes of teh globals are only done after acquiring the semaphore that protects the global. If you did thisfor all accesses to the global you would not have race conditons with globals.
    Unfortunately this is a lot of work because now you have to deal with creating acquiring releasing the semaphores and this has to be done for each value you need to protect from simultaneous access.
    Now if there was an easier way well then....
    BUT THERE IS!
    It turns out that when a VI is not reentrant (like in a LV2) LV implements a scheme that prevents simultaneous execution of the VI. So by using a LV2 you pick-up the resource locking with ZERO EFFORT!
    So being lazy, I use the method that is imune from race conditons from the very begining. That way when my customer asks "Can I manipulate the cal values from any of the machines on the network?" I can say "YES, that was functionality is supported by the design".
    I could not say that if I implemented the cal via globals.
    So that is why I push LV2's and and discorage globals.

  • What is the maximum number of characters allowed for an e-mail account password?

    By trial and error I found that 11 characters were too many and 9 characters are OK.  I suppose the limit is probably 10 but why does the iPad just tell me that I have too many characters in stead of complaining about my User Account or Password being wrong and causing me to waste a few hours trying to chase down e-mail configuration options?
    I hope this posting will save others some pain.

    Not all email providers have the same password requirements. Without knowing who your email provider is, your information is of minimal use.

  • What is the maximum number of characters in an Oracle 10G Instance Name

    All,
    Can I know what is the maximum number of characters in an oracle 10g instance name under AIX? Is it 7 characters or 8 characters?

    One should really make the difference between db_name and instance_name: if instance_name default value is db_name it can be different
    (even on a non RAC database).
    For example with Oracle 10.2.0.4 you can create a database named DB78 with instance_name=DB12345678:
    $ uname -a
    Linux lx01.localdomain 2.6.18-92.el5 #1 SMP Fri May 23 22:17:30 EDT 2008 i686 i686 i386 GNU/Linux

  • What's the maximum number of Apple TVs that can be displayed in the AirPlay list?

    We have 50 conference rooms all on the same network and are considering equiping each one with an Apple TV for AirPlay Mirroring our iPad 2s to the rooms projector, or TV. What is the maximum number of Apple TVs that can be displayed in the AirPlay menu to select the correct Apple TV for the conference room being used?

    From what you're saying it sounds as though you wouldn't want to Airplay to all AppleTVs at once, just identify them when that specific room in use?
    This is one of those uncharted territories wheer most domestic users will not require such a set up - Apple provide no official info about this, but they'd be your best source to ask.

  • What is the maximum number of fields in oracle 9 ?

    How many fields can i put in a single oracle file ? Can i compare the fields to a column in a spreadsheet ? If so, i want to know the maximum number of columns possible in an oracle database (if i take the exemple of microsoft access, i have a limitation of 255).
    I thank you in advance for your answers.
