Example of how group by on ODI

I already post a question on that subject but i didn't succeed to create so if anyone have a example or a tutoriel.
I explain my case :
I have a table with a field containing a bank account, another field containing the amount of an operation on this account. I want to make a sum of operations by account. The request will be something like :
Select SUM(operation),account of TableLedger group by account.
Thanks.

Hi,
If you use the SUM function on the target mapping (operation) then the query that ODI generates will automatically contain a group by.
Cheers

  • Where do I find examples of how to use formula functions? Online help only provides syntax

    Hello,
    I would like to run a formula ( for my custom field in Project 2013)  that allows me to see the Finish Time e.g. 17:15 for a task.  I am trawling through the online help to determine which one is best but I would like to read some examples
    of how a function can be used. I hoped Help may do this but no.
    Hope you can point me into the right direction.  Thanks in advance.
    Alan

    Alan,
    Yeah I agree, the on-line help is lacking in information on how to actually USE a function. However, there are some places that may help. Here are a couple, I'm sure there are many others.
    https://support.office.com/en-nz/article/Project-functions-for-custom-fields-7e525143-380f-4083-8d5a-3ecc6ba44f22
    https://msdn.microsoft.com/en-us/library/office/ee767700(v=office.14).aspx
    Since many of the custom field formulas are also used in VBA, I've found the object library reference for VBA to be very helpful in understanding and setting up custom field formulas. To get the the object library, go to Developer/Code group/Visual Basic.
    Once the Visual Basic Editor window opens, hit View/Object Browser. Hit the Help menu and select the Help for Visual Basic. Type in the function of interest.
    However, you say you want a custom formula to see the finish time for a task. You don't need any customization to see that. Simply go to File/Options/General tab and select a date format that includes the time.
    Hope this helps.

  • Looking for a simple example of how to query all the accounts

    I'm new to the web service model in oracle crm and have been trying to just get a list of the accounts in the system. I generated a .cs class from the account wsdl and added it to my asp.net project. I'm able to get a handle on the account class but not sure the right syntax to make a call out.. As a fyi - i also have been able to login thru the service and obtain a session id.. so I'm that far..
    Are they any existing code examples on how to query this? This is what I have so far but i throws an exception -
    Account act = new Account();
    act.Url = "https://"+dbcon.serverName+"/Services/Integration;jsessionid="+ sID;
    AccountWS_AccountQueryPage_Input qbe = new AccountWS_AccountQueryPage_Input();
    AccountWS_AccountQueryPage_Output qRet;
    qbe.ListOfAccount = new Account1[1];
    qbe.ListOfAccount[0] = new Account1();
    qbe.PageSize = "20";
    qbe.StartRowNum = "0";
    qbe.ListOfAccount[0].AccountId = "";
    qbe.ListOfAccount[0].Description = "";
    //act.CookieContainer = .... is this line needed?
    qRet = act.AccountQueryPage(qbe);
    return qRet.ToString();
    Thanks in advance for your help - Todd

    Hi,
    I am doing the same thing but I am not sure what is Account1 in your case. Can you show me the implementation of Account1 class?
    Account act = new Account();
    act.Url = "https://"dbcon.serverName"/Services/Integration;jsessionid="+ sID;
    AccountWS_AccountQueryPage_Input qbe = new AccountWS_AccountQueryPage_Input();
    AccountWS_AccountQueryPage_Output qRet;
    qbe.ListOfAccount = new Account1[1]; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< qbe.ListOfAccount = new ListOfAccountQuery();
    qbe.ListOfAccount[0] = new Account1(); <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    qbe.PageSize = "20";
    qbe.StartRowNum = "0";
    qbe.ListOfAccount[0].AccountId = ""; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    qbe.ListOfAccount[0].Description = ""; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    //act.CookieContainer = .... is this line needed?
    qRet = act.AccountQueryPage(qbe);
    return qRet.ToString();
    On the right is my line of code. The ListOfAccount member of AccountQueryPage_Input has datatype ListOfAccountQuery. In my case, a NULL is returned after the call.
    Did you code work in the end?
    Thanks

  • How do I fix the compatibility issue between my iPhone 4S with iOS 7 and my Pioneer car stereo? There was no problem with iOS 6, but now I get a message saying "this device is not compatible" and so I can't use Netflix for example. How do I fix it?

    This is a typical response from the manufacturer. Did you try the fix that Lawrence mentioned. When Apple or any other phone manufacturer update phone software, they have the latest Bluetooth installed. It is usually the problem with the radio manufacturer that they devices are using the older Bluetooth protocols. You can try this support document http://support.apple.com/kb/TS3581 and see if anything there helps, but generally it requires the radio manufacturer to update their firmware.

  • Req any examples of how to use a USB midi controller​/keyboards with Labview TIA

    Req any examples of how to use a USB midi controller/keyboards with Labview TIA

    Hi,
    To access the MIDI ports you will need to call the Windows SDK. To send MIDI commands is relatively easy, here is an example that shows you how to send data to a MIDI controller or keyboard.
    As far as input goes, this is the hard part. There are a series of functions that you need to call to open up the device, set some buffers and and possibly a callback to get notifications on the incoming data.
    Reading MIDI data will not be an easy task, your best bet will be to implement this in a DLL and call that DLL in LabVIEW, there should be some code available o the web.
    = "http://msdn.microsoft.com/library/default.asp?url​=/library/en-us/multimed/htm/_win32_multimedia_... is a link to the Windows multimedia functions that you could use for MIDI input.
    Let me know if you have any further questions.

  • Need an Example for How to call a Stored Procedure using DBAdapter

    Hi
    I am trying to invoke a stored procedure in Oracle Database using DB Adapter. I have successfully invoked and when i try to run it i got the following error.
    oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException: Client received SOAP Fault from server : Exception occured when binding was invoked.
    Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'ExecuteScript' failed due to:

    Check to ensure that the API is defined in the database and that the parameters match the signature of the API.
    This exception is considered not retriable, likely due to a modelling mistake.
    To classify it as retriable instead add property nonRetriableErrorCodes with value "-917" to your deployment descriptor (i.e. weblogic-ra.xml).
    To auto retry a retriable fault set these composite.xml properties for this invoke: jca.retry.interval, jca.retry.count, and jca.retry.backoff.
    All properties are integers.
    I am trying to have a Out Parameter in my Procedure. Please provide me an example on how to invoke a Stored Procedure using Out Paramter using DB Adapter.

    Hi,
    It looks more like an Oracle error and not within the DbAdapter.
    Try to test first your procedure from PL/SQL or other developer you are using.

  • Simple HTML example on how to display a live stream?

    Hi all
    Is there anyone who has a HTML example (or can give an URL with a page) that has the Adobe Flash player displaying a live stream (and not a file)?
    There is one in the installation under "Flash Media Server Start Screen" but it was too complex for me to understand. I just need a simple example on how to display a live flash stream in Adobes own web player.
    Thank you very much :-)

    Hi,
    Here is the html code.
    <html>
    <head>
    <title>Flash Media Player</title>
    </head>
    <object width="550" height="400">

    <embed src="somefilename.swf" width="550" height="400">
    </embed>
    </object>
    </body>
    </html>
    And here is the action script code of player.swf.
    import flash.net.NetConnection;
    import flash.events.NetStatusEvent;
    import flash.net.NetStream;
    import flash.media.Video;

    Please do the following before using the actionscript code:
    Add a button called start in fla and keep its instance name startBtn.
    create an application called sample in FMS and publish a live stream called "LiveStream".

  • An example of how far ArchLinux has come

    Congratulations to the developers and packagers at Arch! I want to give a perfect example of how great this system is:
    My system hasn't been touched for seven months.  I boot the system up, and do two things:
    1) #! pacman -Sy pacman
    2) #! pacman -Syu
    3) reboot
    Everything still works just like I had it back in January, hats off to y'all

  • Example on how to use the NI "saving a front panel img to file" on a prog.

    New to the labview program - I'm trying to save the front panel of the displayed output to file. I downloaded "Panel_Image_to_File.zip" from the NI site. But I'm having problem using the code to our program so as to save the image as a jpeg.
    A simple example on how to use the code or any other code that will be able to save the front panel to a specified folder will be great.

    All you should need is an invoke node of VI class and the the method Get Panel Image. Wire the Image Data output to the Write JPEG File on the Graphics & Sound>Graphics Formats palette. The Invoke Node is on the application Control palette. When it's on the diagram, right click and select Class>VI Server>VI. Right click on it again and select Methods>Get Panel Image.
