Multiple constraints on the same column

Hello experts, we can use Multiple forced on the same column in oracle as creating table, I want to add a key single and forced to check on the same column is this possible? Thanks in advance,

If you want, seems to be possible

CREATE TABLE t1

(col1 VARCHAR2 (50))

CONSTRAINT ck1 CHECK (col1 IN ('A', 'B', 'C'))

CONSTRAINT PRIMARY KEY (col1) pk1

  • Multiple values for the same column in the columns of diffétent in the same row?

    Hi all
    I wonder how you can display different values for the same column in different columns on the same line. For example, using a CASE statement, I can:

    CASE WHEN CODE IN ('1 ', ' 3') THEN COUNT (ID) AS 'Y '.
    CASE WHEN CODE NOT IN ('1 ', am') THEN COUNT (ID) AS "N".

    Yes, that will produce two columns but will produce null values to empty and also two separate registers.


    Any ideas?

    Thank you

    Are you sure that this code works for you?

    Select ID
             ,CASE WHEN MODE_CODE IN ('1', '3') THEN COUNT( No) END as "Fulltime"
             ,CASE WHEN MODE_CODE NOT IN ('1', '3') THEN COUNT( No ) END  as "Other"
    From table
    group by ID
    

    I guess the code above fails because MODE_CODE is not in your group by?

    My suggestion would be to put the CASE in the COUNT:

    Select ID
             ,COUNT(CASE WHEN MODE_CODE IN ('1', '3') THEN No END) as "Fulltime"
             ,COUNT(CASE WHEN MODE_CODE NOT IN ('1', '3') THEN No END)  as "Other"
    From table
    group by ID
    

    CASE expressions return no. when the respective conditions are true and NULL otherwise.
    COUNTY will have non-null values.

  • I use Thunderbird on multiple computers to the same gmail account but I have a laptop with little memory, so I need this laptop only to download a few files

    I use Thunderbird on multiple computers to the same gmail account. I have a small laptop with very little memory and it runs out of disk space when it downloads all my folders. I would only download some of my file on the laptop, but keep all the folder on my other computers because they do not have problems with disk space. When I unsubscribe records in 'manage folder subscriptions' then he cancels his subscription on all my computers, not just the laptop. When I go to 'Properties' on the folder and sets 'retention individual police' these settings are not applied at all. What can I do?

    All of the messages in each folder will appear in your message list. But this does not mean all the bodies of messages are downloaded, if you have properly configured the parameters of the disk. If what I described above stuck in your settings then Message body should be downloaded only 'on demand' when you click on each message.

    To confirm this install the addon glodaquilla, which has a column "on the disk" that indicates if a message is on the disk. If you want, after you have installed the addon set Thunderbird to work offline, so it does not download message body when you click in the list of messages.

  • How to switch between multiple windows in the same application?

    Hello

    I use OS X Capitan version 10.11.13 and I'm trying to find an easy way to switch between multiple windows in the same application by using CTRL + alt or different keys.

    Here is what I feel...

    Let's say I have Outlook, Google Chrome, Safari, iTunes and apps 'about this Mac' open.

    I open the new message window in Outlook and another Chrome window. I have therefore 2 separate windows in Outlook and Chrome.

    With that, I'm unable to move the composition and the window main outlook which is so annoying. Let's say I want to read the emails by the prospect main window and transfer of the content of the compose window! The command + tab doesn't take me to the main window of Microsoft outlook! Even if there were the last visited / applications window. This constraint is not intuitive, unless it can be configured in the settings?

    Strangely, I can't switch to the "about this Mac" window.

    The work around is to use the function (F3) mission button and click on the window, that I want to use or click the "Outlook" application on the dock icon and choose the window in the list.

    Does anyone know how switch between different windows in the same application by using a key combination or one another method other than listed above?

    Thank you

    Avinash

    In general, an Application that can open multiple windows provides a "Windows menu" you can choose the window you want.

    an alphabet by typing in a cell gives drop down suggestions from previous hits on the same column. But how the drop down to choose the suggestions of the other columns and other sheets.

    Hi mdsavol,

    Your observations are accurate. The 'suggestions' are previous entries in the same column that correspond to what has been entered so far in the active cell. The only direct user control is to activate the function turn on or off in numbers preferences > general.

    There are other ways to include or exclude items of suggestions:

    • To remove typos in the suggestions list, the user must correct the typos in the cell above the active cell. If they are more in the list, they won't be presented as suggestions.
    • To include selections added to the list, the user must enter these suggestions in the individual cells above the active cell and column where they are wanted as suggestions.

    There was a request here a while there is a list of suggestion 'live' similar to those of some websites, which offers a descending list of possible entries as a type in an input box.

    The only way I see to reach a solution similar to what you have asked is to use as many lines at the top of the non-en-tete of the table section to list the items likely to repeat in your table, and then hide the lines. You'll need a list for each column where you want to use this feature with a list previously planted. Existing items will then require a likely hit up to three, then a click to choose from a list small enough to enter a value into a cell. News he will need to enter in full the first time, but after that it will be put on the list and answer the same thing as the terms preseeded.

    While your setting upward (or decide not to do), consider going on the menu of number (in numbers), choosing to provide feedback from numbers and writing a feature in Apple request. Describe what you want. Explain how he could help the average user numbers, and then hope for the best.

    Kind regards

  • Multiple copies of the same mail and "unresponsive".

    I have fought with Thunderbird for about a week now and have had no chance to solve my problems. Any help would be greatly appreciated! I tried all the suggestions on the FAQ page.

    Here are my symptoms:
    -Make multiple copies of the same email with the same time stamp.
    -Not pulling new e-mail messages.
    -Whenever I try to navigate upwards or downwards in the Inbox or open an email TB will does not.
    -J' got warnings from the following script:
    Script: resource://gre/modules/XPCOMUtils.jsm:323
    Script: chrome://messenger/content/mailWindow.js:179

    Here is what I tried:
    -J' completely removed and reinstalled TB (and recovered my profile).
    -J' have compressed files.
    -J' rebuilt the database world.
    -From TB in safe mode does not seem to make a big difference.

    Fortunately, I have access to webmail via my ISP and it works fine.

    Thank you!

    McAfee has released a faulty update, please contact them for support on changing the setting to something that actually works.

    I saw a poster here today who used their support chat and they 'fixed a few adjustment' and now all is good.

  • Firefox does not work for multiple instances of the SAME user account on Windows Multipoint Server 2011

    We have a PC HP of MulitSeat MS6200
    It runs Microsoft Windows MultiPoint Server 2011 (which seems to be a twisted version of Windows 7)
    It is implemented in a laboratory of computer science and students connect you using their account for shared room - IE multiple instances of the same user accounts are currently running on the PC at the same time.
    The first student to run Firefox can work with it without a problem.
    However, when another student try to start firefox they get the following message:
    Firefox is already running but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

    Cannot start Firefox using a profile that is already used by someone else.
    Each Firefox instance needs its own profile or you will get this error message.

    Use-no.-line switch remote control to open another instance of Firefox with its own profile and to different instances of Firefox running concurrently.

  • Firefox open multiple tabs of the same site at the same time, why

    some site that I visit - when I try to use yahoo or facebook, messaging - multiple tabs of the same pop up and open and bring me to this last open tab - never let me finish what I'm doing. Why is this happening?

    I had this problem (when I opened Firefox, Facebook kept several tabs open, even when I was on other sites such as Google).

    After you restart Firefox with modules disabled (via the Help menu Firefox), I enabled first of all Plugins, then the Extensions, on-to-one.

    The problem is back only when I activated Facebook Toolbar 1.7.3 and disappeared when I disabled it again.

    This extension has been updated on 3 August 2011, which is probably when the problem started to appear (worse gradually). The extension tries to integrate some utilities of Facebook with the browser, but it's something that I can easily live. If you are having similar problems, try disabling Facebook Toolbar 1.7.3

  • Multiple accounts with the same email

    I have an account I can not connect to after my daughter it has disconnected. I tried to reset the password, but I get an email on my account to other girls: S (same email)
    I guess I have 3 accounts with the same email, but only the latter can created recover!
    Not even my main Skype has a chance

    I'm not 100% sure but it is most likely that I used the same email to whoever I have to reset - what can I do?

    In fact, this morning I managed to log on to the account of an iPad without frills but the pc refuses to sign ^ ^ ^? "Skype cannot connect" - what is happening?

    I also discovered that I could connect via a browser, but not via the Skype program... So I uninstalled and installed again and it's working now...
    I've now changed the email so I have 3 accounts with the same email address as Skype seems not to be able to manage multiple accounts with the same email!

  • IMac is not able to share multimedia files with multiple users on the same computer.

    We just bought a new IMac that we were very excited.  We have phones Apple and iPads, replacement and ten year with a new Mac old PC made since.

    Now, the trouble begins. For more than ten years Windows had several usernames on the same machine and have been able to have a shared folder only for music, pictures and video that my iTunes program and others could acsess and share from several user names. This kept all in one place for new photos families by me or my wife and our 30 gigabytes of music that comes from our CDs was available at bolt of us. Now in train to implement on IMac should be easy but is impossible.  after transferring the music to my login information, it cannot acsess all files on my login. I am not even able to share or provide his acsess. I can move the iTunes folder to my shared folder. She can get acsess now but iTunes says that the library file is locked. I worked with care from Apple on the phone for that sold, but they believe it will not be possible without creating two copies of the 30 gigabytes of music for each of us. who would take more hard drive when it failed too.  Sharing is not any help. These files were before iTunes. I'm not pay 30 dollars a month to store in icloudcor use a google reader slow to the Internet connection when everything's fine here. Apparently Applow programmers do not believe in sharing of multimedia files between two users on the same device, even if a PC does that very well. My choice here is so far have duplicates of all the photos, music and videos loaded on the disc for me and my wife, charge all the media for an external hard drive which for some reason any all Apple programs will share, or return the mac to another PC that will be able to make several connections with sharing music and photos. Apple if you are reading this you are 10 years behind on that. Not everyone is born in the last five years and bought their music on iTunes to be able to use home sharing. Home sharing cannot help this. your applications should be able to be told to use the media files shared without import copies to readers of the user. I am very disappointed. Someone else has any ideas for that?  I have pictures, not iPhoto. I have a week more to be able to return it. I'm not interested in making a fake account that is always connected to share or maintaining of me constantly connected. It should have been easy, I had to be happy to play with new software.

    Photos, iPhoto and iTunes libraries must appear on an external hard drive that is formatted as shown below to be used by multiple users on the same Mac:

    So get a properly formatted external HD and move your iPhoto/pictures of her as well as your iTunes library.  This way all your iMac users can access and use both libraries.

    An alternative to the external HD method is to partition your internal hard drive into two partitions, one for libraries.  It is formatted as shown above and be large enough to contain the libraries and allow the expansion of libraries.

  • [Q] can Vision track multiple objects in the same area - objects that might cross?

    Hello

    Sorry for this long title, but this is my question.

    Can Vision track multiple objects in the same area - objects that could cross?

    Because I'm able to do, extraction of XY, but it seems that "IMAQ County objects ' don't follow framework after but framework opposed, but extract the coordinates XY always in the same way, as for example from top and whenever he sees an object, it retrieves the XY, but if the objects pass through (then it will extract XY without worrying that the objects was the earlier but just based on"scan from top to bottom").

    That's why I open this topic in the forum of Vision no part: http://forums.ni.com/t5/LabVIEW/Sort-XY-by-closest/td-p/2440428

  • Entries are concatenated in the same column in the excel file

    Hi, I really need help in this emergency. The problem is when I open the spreadsheet file after you run the program below, all the values that I believe are concatenated in the same column. However, there are 2 different analog inputs which I want in 2 different columns. I'm getting the 2 waveforms in the same graph, but when I open the excel file, it seems that the entries are concatenated in the same column. Someone knows how to fix this? Thank you very much.

    Hi Ben 64,.

    Thanks a lot again. I did as you said and I removed the dynamic data and logged files added directly to the results. I'm still checking if the program works as I can branch only when I return to work tomorrow. Tell me if you think it might be able to work this time. Thanks a lot again!

  • Is it possible to set up for multiple users on the same computer to avoid entering the e-mail and the password

    Original title: Multi users

    Is it possible to set up for multiple users on the same computer to avoid entering the email and password every time that a new user want to check emails?

    Hello

    Welcome to the community forums of Microsoft and thanks for posting the question. According to the description, you need help in the creation of multiple user accounts. I've surely you will help find a solution on the issue.

    What is the operating system installed on the computer?

    User accounts, several people can easily share a single computer. Each person can have a separate user account with unique settings and preferences, such as a screen saver or desktop background. User accounts control files and programs users can access and what types of changes users can make to the computer. As a general rule, you'll want to create standard accounts for most computer users.

    If you use Windows Vista or Windows 7, see the article below:
