• Set initial value as the number of sequence/date/from the user

  Hi guys, I created a datablock and set up the user interface to allow users to insert all the data they need, however my table has a:
  
  ID - which is uniqe with each entry of the table is then gernerate by a sequence (that I created on the database), but when I put seq.nextval in the initial value on the datablock it says that I can not do that, so how can I use the sequence to insert the value in this field in the database. It's my first key in my whichobviosuly database my users cannot enter data for, on the contrary, it is generated automatically.
  
  User - in the same way in the datablock is a user field that has the user that inserted record, I know I can set the default for this field, but how to make the user automatically insert through forms on the database.
  
  Same again how put SYSDATE is automatically entered in the field date when the user submits the file?
  
  Any help on this would be GREATLY appreciated.
  
  Thanks in advance.

  The DUAL table:
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/queries009.htm#sthref3198

  With: new, you reference the column should be inserted (in a trigger to update you: old and: where new: old contains the value before and: new value after the update of the column)

  Regarding your real problem: without a few pieces of code fails and you did, it's a little difficult to say what happened here. If you could get better answers by sharing.

  Sharing also the Versions of database (4 digits) and Versions of forms is important in order to obtain a response apropriate.

  Anyway: you seem to be new to the whole forms / SQL / PL/SQL stuff, so I might suggest:
  http://Tahiti.Oracle.com is a very good starting point for SQL and PL/SQL. This isn't a RTFM but rather a Council. Once you got used to you will like it. For my part, I could not live without tahiti: D.

• How to extract specific data from the user to view?

  Hello

  I have a requirement I need to display only the Session_user-specific data in the table. Scenario is that if the user belongs to a specific region should be able to see data for that specific region only.

  I think passing the session_user view query name but don't know if it of possible or not. If possible how to do this.

  What is the best way to achieve this?

  Thank you

  Hello

  If you use the ADF for authentication security, the user name is then accessible from the context of the ADF in British Colombia ADF. You can then

  1. create a view of the criteria in British Colombia ADF to a specific view

  2. set the display criteria to use a variable binding

  3. use groovy to add the value of the bind variable

  -set the type of value of 'Expression '.

  -Add adf.context.securityContext.userName

  4. go in the Module--> Application data model

  5 Select the instance of the View object

  6. press on "change."

  7. Select the view test

  If you download the example in this article: Oracle ADF: security for everyone so you see that users have a profile page containing data for the authenticated user. Sound by using the method described above

  If you do not use ADF security you can always use this approach. Instead of providing the value of the variable bind using Groovy you can run the view object using executeWithParams operation in this case, you can read the value of the authenticated user to the side view ADF. The binding variable would not be set to the Expression in this case though.

• Write and read data from the user's local file system

  Hello

  I write my first extension for dreamweaver. My extension should backup the data on the local file system of the user. I know that I can use DWfile.read () and DWfile.write () as described in Chapter 2 of the Dreamweaver API reference. I store the data using the XML format. What is the best way to read and parse the XML data in the file? What is the best way to write the XML data in the file?

  If you recommend one format other than XML, I'm open to suggestions. The data are only a few configuration information for the extension which should be persisted.

  Thank you

  mitzy_kitty

  How will the data be used? If it is used by JavaScript, use JSON format which includes js. If you use XML, then you will need to find an XML parser to read the data.

• Inserting data from the user-defined Type

  Hi all
  
  I have the following type

  create or replace type answer_obj is object (all_employee_seq integer,questionseq varchar2(10),text_answer varchar2(4000),optionseq varchar2(10));
  
  create or replace type answer_tbl is table of answer_obj;

  I have the procedure (within a package) that pulls in the python papers.
  

  TYPE answer_tbl_type IS TABLE OF question_answer%ROWTYPE
                                 INDEX BY PLS_INTEGER;
  
  PROCEDURE submit_survey (p_answers IN OUT answer_tbl)
     IS
        l_answers_tbl   answer_tbl_type;
     BEGIN
        FOR i IN p_answers.FIRST .. p_answers.LAST
        LOOP
           l_answers_tbl (i).all_employee_seq := p_answers (i).all_employee_seq;
           l_answers_tbl (i).questionseq := p_answers (i).questionseq;
           l_answers_tbl (i).text_answer := p_answers (i).text_answer;
           l_answers_tbl (i).optionseq := p_answers (i).optionseq;
        END LOOP;
  
  
        FORALL idx IN l_answers_tbl.FIRST .. l_answers_tbl.LAST
           INSERT INTO QUESTION_ANSWER
                VALUES l_answers_tbl (idx);
     
     END;

  My question is, is it better to insert the data directly from the (record) (records) argument using for LOOP INSERT or the conversion of the argument in an associative array and a FORALL?
  As you can see, it's a FOR LOOP to set the values in the array and then by the FORALL.
  
  I think the above is even faster because of the first LOOP IS done in memory and real integration is carried out with FORALL.
  I want to get as many opinions.
  
  
  See you soon,.
  Joel

  Hello

  Because you created the SQL Types, what just to do this within your procedure?

  INSERT INTO QUESTION_ANSWER (all_employee_seq, questionseq, text_answer, optionseq)
  SELECT all_employee_seq, questionseq, text_answer, optionseq
  FROM TABLE(p_answers);
  

• The data of the user of a Flex application recovery

  Hello! I need to use an application Flex (not a form guide) in the workspace.

  I am able to make a Flex application that is activated in the workspace, but I do not know how to retrieve data from the user.

  I know that if I use a form Guide, I can use a custom renderer Service that can retrieve data from the user, but how can I do the same if I don't use form Guide, but a pure SWF (variable type is form)?

  Thank you

  Alessio

  There is a way you can get the information of the user of the Flex application. You can get the user name, e-mail address and such things.

  You can see the following blog on how to do it: http://michael.omnicypher.com/2008/12/get-current-user-for-workspace-enabled.html

  If you need other data, you may need to make a call service or remote Web access once the Flex form has loaded.

  In the next version of LiveCycle, you will be able to use the same concept as the service rendered.

• Slow response from the user interface with acquisition of data of type long time

  Hi all

  I have a question to ask more out of curiosity than necessity right now. I've built a program that acquires data from the accelerometer and the Treaty in a number of ways: filtering, FFT, FRFS, things like that, but the answer of the UI is still slow, because I need a resolution of frequency of 0.2 Hz for my data domain, which means that the sample acquisition time is 5s and all this awaits before execution.

  My question is this: is there a way to completely isolate the user interface of data acquisition so that it responds immediately?

  I tried a design model of producer consumer with queues, but found everything to be always waiting for samples to be taken. Maybe it was exactly as I did.

  Thank you

  Phil

  If you need to sample for 5 seconds in order to have enough data to analyze, so unless you can "predict the future" and "knowing" the five seconds of data, simply wait for the data that arrives.  Using parallel loops of producer-consumer will allow data acquisition to proceed (for the next 5 seconds of data) while you do the analysis, but you still have to wait for the data to be analyzed.

  Note that the previous paragraph assumes you are collecting data in 5 seconds 'chunks' and analyze each "chunk" (independent) on arrival.  You could also do something like having a "second 5 sliding window" which moves, say, a second at a time, giving your FFT a finer resolution of 'time' (at the expense of their independence).  This would be a (slight) change in your loop of producer (you want to taste in 1 second pieces, accumulate 5 these pieces) and the consumption loop (start analyzing, spewing a FFT every second, while replacing the older "chunk" with the most recent - a queue with loss can do for you).

• Read data from the text column in report

  I have a sql report with an editable column created using apex_item.text (5);
  
  I tried to read and insert the data from the column in a table, using this process
  
  because me in 1.apex_application.g_f05.count
  loop
  insert into table (col_a, col_b)
  values (apex_application.g_f05 (i), apex_application.g_f04 (i));
  commit;
  end loop;
  end;
  
  but without success.
  
  The message when I execute is ORA-01403: no data found.
  
  What is the error?

  HI lkefur,

  Try to debug it.

  The reason behind this is that your report do not have the of4, fo5 (one) as text fields at all.

  try to delete value n f04 normal text and check, even to f05.
  I think that most probably the reason whether shud.

  You can view only the source of the page and check which names are your text fields of the report to help.

  Kind regards

• Flatten to a string to send arbitrary objects by messages from the user interface?

  Hi people,

  I am trying to send arbitrary data by messages from the user interface defined by the user to my labview interface. Something funny happens then: if I send the data through the message of ui, it seems I have something strange. There is only one character or nothing in the message of the user interface that reached my reminder.

  It seems that flatten channel also creates control characters that are interpreted by NI TestStand and Labview not as members of the chain, and for this reason I only get incomplete data. within the action of testand, which creates the flattened data, I put a dialog box to display the string data, and it seems that at least up to 255 (ascii) characters are used.

  Is there something like uuencode/uudecode to avoid this problem?

  Thanks in advance

  Okidoki, found.

  His «binary"produced by «Flatten the string» string Apparently I thought, the LabVIEW data type is incompatible with the API of TestStand from LabVIEW. In conclusion I would classify this as a bug (sorry people, at least there should be documentation) API for LabVIEW TestStand 2014.

  As a solution, I use flatten it in XML, which is a printable and human readable 'normal' string.

  It was trial and error, and I'm not enjoying this.

• Unable to delete the data from the Safari Web site...

  Hello.

  I need help with my Safari browser on my Mac.

  Im trying to remove all Web site data with the following procedure:

  Safari-> Preferences-> privacy-> Remove All Data Web site...

  His does not work. Before clicking on the button I have 108 Web sites stored cookies or other data, I click the button, and nothing happens... I'm still 108 cookies.

  I also did the following:

  . - activate the Menu developer and Cache empty and tried again... nothing

  . - used CleanMyMac v3 and it says I don't have cookies.

  . - order iCloud Sync of Safari on the computer and try again... same problem

  . - removed manually com.apple. Safari. Secure

  Any help will be great. Please let me know if you need any additional info.

  Thank you.

  Hello DZanvettor,

  Thank you for using communities of Apple Support.

  If I understand your message that nothing happens when you try to remove the Safari Web site data. I know how it is important for you to be able to remove the Safari Web site data. I recommend that you restart your Mac into safe mode and see if you can remove the data from the Web site in secure mode.

  Here are the steps to restart your Mac in safe mode:

  Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening.

  From your Mac in safe mode does the following:

  * Check your startup disk and attempts to fix problems if necessary directory
  * Loads only required kernel extensions
  * Prevents the elements start and the login items open automatically
  * Disables installed user fonts
  * Delete font caches, hiding the kernel and other files of the system cache
  * Together, these changes can help resolve or isolate issues related to your startup disk.

  Follow these steps to start in safe mode.

  1. start or restart your Mac.
  2. as soon as you hear the startup tone, hold down the SHIFT key.
  3. release the SHIFT key when you see the Apple logo appears on the screen.

  After you delete data from the Web site in safe mode restart your Mac and allow it to start up as usual. Then test the issue again.

  Best regards.

  If I clip named firstScreen how to fill with data from the rackUSA of the table, using the presented functions iterateArray

  I tried in a movieClip

  CustomClass.iterateArray (rackUSA); but it does not work

  Any suggestions

  I want to clarify the use cases.

  1 load data into the document class

  2. display a welcome message

  3 allow users to navigate through the products.

  Q1: Do you mean by 'welcome message' a user interface that allows to start navigation?

  Q2: Products appears the same way. I mean, consider that product display will have a uniform provision?

  If the answer to Q2 is Yes, I would:

  1. create a class that features products. Call ProductDisplay

  2 transfer data (subset of XML related to a particular product - in your case, it may be an object in the position of the table) in an instance of ProductDisplay

  I would like you to consider the following.

  It is a good practice to do OBJECT oriented programming class as little as possible each. This means that a class must have a very focused functionality. For example, ProductClass you perform tasks related to laying on the presentation of the product. With this in mind, it is best to delegate, say, loading image to a separate category. Believe me, when you do – your life will be much easier if you do features as granular as possible even if sometimes it feels like an overdose.

  So here's the sketch of your classes. I wrote it just to illustrate the idea. I did not check the code during execution is definitely buggy.

  Read my comments below also.

  It is a class of product image that load the image:

  
  package
  {
       import flash.display.Loader;
       import flash.display.Sprite;
       import flash.events.Event;
       import flash.events.ProgressEvent;
       import flash.net.URLRequest;
  
       public class ProductImage extends Sprite
       {
            // image url
            private var _url:String;
            // loader
            private var _loader:Loader;
            public function ProductImage()
            {
                 if (stage) init();
                 else addEventListener(Event.ADDED_TO_STAGE, init);
            }
  
            private function init(e:Event = null):void
            {
                 removeEventListener(Event.ADDED_TO_STAGE, init);
                 _loader = new Loader();
                 _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoad);
                 _loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
                 _loader.load(new URLRequest(url));
            }
  
            private function onProgress(e:ProgressEvent):void
            {
                 // display progress if needed
            }
  
            private function onLoad(e:Event):void
            {
                 _loader.contentLoaderInfo.removeEventListener(Event.COMPLETE);
                 _loader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onProgress);
                 addChild(_loader);
  
            }
  
            public function get url():String { return _url; }
  
            public function set url(value:String):void
            {
                 _url = value;
            }
  
       }
  
  }
  

  ProdustDisplay class. Note how the product class is instantiated

  
  package
  {
       import flash.display.Sprite;
       import flash.events.Event;
  
       public class ProductDisplay extends Sprite
       {
            // hold the metadata
            private var _metaData:Object;
            // an object that holds the image
            private var _imageDisplay:ProductImage;
            public function ProductDisplay()
            {
                 if (stage) init();
                 else addEventListener(Event.ADDED_TO_STAGE, init);
            }
  
            private function init(e:Event = null):void
            {
                 removeEventListener(Event.ADDED_TO_STAGE, init);
                 // only if metadat is set - build interface
                 if (metaData) {
                      build();
                 }
  
            }
            // build interface
            private function build():void {
                 // place prduct image
                 _imageDisplay = new ProductImage();
                 _imageDisplay.url = metaData.image;
                 addChild(_imageDisplay);
                 // do the rest - like description, etc.
            }
            // function that accepts product metadata
            public function set metaData(metaObject:Object):void {
                 _metaData = metaObject;
            }
            // returns metadata
            public function get metaData():Object {
                 return _metaData;
  
            }
  
       }
  
  }
  

  Now in your document class, you can set an unlimited number of instances of ProductDisplay (as slides) and manipulate them. Again, this is just a sketch. Actual implementation of features and code will be somewhat different:

  var productDisplay:ProductDisplay = new ProductDisplay();
  productDisplay.metaData = rackUSA[2];
  
  

  Note: Your code has several inconsistencies - we need to go through them at another time. For now just digest these ideas. I understand that this will involve a refactoring on your part, but once you are done with it - things will fall in place fast.
