• Shape of the apex - how to get the primary key value manually?

  Hello
  
  Whenever I create form by using wizard Apex, he asks me to specify the trigger/sequence/pl/sql function to fill the primary key value.
  
  However, if I want to specify primary key myself (ie. undetermined generated automatically), how I can clarify that?
  
  Thanx

  Hello

  You mean by yourself: by hand or by a pl/sql?

  If you say by trigger, the system does not take on what number is sent. If you can give it "manually".

  May I ask what is the reason for this?

  See you soon,.

• How to get the primary key of the node selected in af:tree

  Hi all
  
  I use JDeveloper 11.1.1.5.0.
  
  I want to get the primary key of the node selected in the af:tree element. I wrote the code below in SelectionListener:
  

      public void drzewkoRwaSelectionListener(SelectionEvent evt) {
          RichTree tree = (RichTree)evt.getSource();
          TreeModel model = (TreeModel)tree.getValue();
          RowKeySet rowKeySet = evt.getAddedSet();
          Object key = rowKeySet.iterator().next();
          
          model.setRowKey(key);
     
          System.out.println(rowKeySet);
          System.out.println(rowKeySet.size());

  The result looks like this:

  [[oracle.jbo.Key[5 ], oracle.jbo.Key[6 ], oracle.jbo.Key[12 ],oracle.jbo.Key[14 ]]]]
  1

  I need the values of the last 2 nodes:
  1: oracle.jbo.Key [14]
  2: oracle.jbo.Key [12]
  
  How can I get?
  
  Kind regards
  Wojtek.

  Hello

  Try this code:

  {} public void drzewkoRwaSelectionListener (evt SelectionEvent)
  RichTree tree = (RichTree) evt.getSource ();
  Model TreeModel (TreeModel) = tree.getValue ();
  RowKeySet rowKeySet = evt.getAddedSet ();
  Key of the object = rowKeySet.iterator () .next ();

  model.setRowKey (key);

  System.out.println (rowKeySet);
  System.out.println (rowKeySet.Size ());

  Object [] keys = rowKeySet.toArray ();
  List (list) = keys [0];
  Keys = list.toArray ();
  * //from the table keys, you can get according to the value you want using as: [2], [3] key *.

• How to add the primary key for the table with the existing data?

  The table is already busy data. There was no primary key before, so for each column, there are some duplicate values.
  
  I want to add a new column, which should be of the integer data type and can automatically incremented, from 001. I tried with Oracle SQL Developer, but it says "ORA-01758: table must be empty to add mandatory (NOT NULL) column. How can I do? Thank you!

  Hello

  Look for the [ALTER TABLE | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3001.htm#sthref4803] command to find out how to add a column (step (1)) and a (step (3)) constraint to an existing table.

  For the step (2):

  CREATE SEQUENCE  employee_id_seq
  START WITH  1
  ;
  
  UPDATE  employee
  SET     id  = employee_id_seq.NEXTVAL;
  

  When you create a sequence, START WITH 1 is the default value, so that the line is not really necessary above... I've included just to show how you could start with any number you have chosen.

• Need urgent help! In my Vision Application, how to extract the parameters of the geometric model specified curve was generated by the template editor OR?

  I have an application of machine vision, in which the geometric pattern match technique was used to find the target in the images of type variant.

  as we know, we do a geometric model by model OR editor in the editor we can adjust the parameters of the curve specified settings to get the desired curves and we derive the custom box to ignore during the match. then we save the use of the same model in our application of vision.

  Now my question is coming. When I program my request for the geometric game. I have specified the parameters of the curve for the entrance of the IMAQ Advanced Setup learn ringtone 2, of course, I have to adjust this identical to the model, but I don't know how we extract the geometric model. I tried all the methods, for example, I can read data custom, IMAQ get characteristics of the geometric model(it's just for the basic functionality? so is there even a VI based edge?), even at anasys PNG file formats! But I can't read the info of the geometric model by myself!

  It is also illogical to adjust the CURVE SETTINGS manually again for the " IMAQ Advanced Setup Learn Pattern 2" after that I already have in the template editor OR!

  Hello

  Why do you need to specify the curve settings once again, if you have already built a model using the template editor? You don't need to use "IMAQ Advanced Setup learn geometric model 2 VI" to find games (see the attached example).

  You can wire the 'curve settings' control to 'IMAQ configuration geometrical game model 2 VI', but the values are not used if wire you a Boolean true to the node "use learning curve settings" (it's like that by default). To prove it, I enclose a small program with pre-created model (using the template editor) for a geometrical alignment. The model and the test of three images are also included.

  Try changing the settings of the curve with the 'use know curve settings' enabled, and you will see the corresponding score remains the same. Disable the Boolean control, then try to change the curve settings.

  Also take a look at the detailed help for "IMAQ configuration geometrical game model 2 VI", specifically the "learning curve parameters of use."

  I hope this helps.

  Best regards

• How to extract the signal from the waveform of my power level designated?

  Hi all

  How can I extract the signal of the waveform accroding to the power level? I read the Trigger & Gate .vi, but this vi retrieves the signal duration. I want to extract the signal depending on the power level.

  As shown in the following figures, the signal I want to deal with is between 130000 to 140000, if I Zoom, I can see the useful signal is between 135400 to 138200. The question is how to extract the signal in the area?

  I tried the sub_NoiseEst_And_Chop_Shell.vi in the example of Packet_based_link also, but this Subvi seems to be a bit slow. Can someone give me the best advice? Thanks in advance!

  

  

  I'm working on something similar, but have not had time to fully develop.

  My idea was to use an envelope detector (low pass filter) and then use a detection of energy VI on the envelope.

  Here is where I left

• How to refer to the primary key column of newly inserted rows of tabular form

  Hello

  I use APEX 4.2.0.00.27 with Oracle DB 11.2.0.3.0.

  I work with a tabular presentation wizard-created for insert and update a table using the integrated SRM process (sequence 10).  I'm trying to use a process of anonymous block of PL/SQL (sequence 30) to make another manipulation of table after the records were inserted or updated.  The manual process is associated with my tabular form and I use the variables of name of column binding in my program block.

  My (rsn_test) table has 3 columns: test_id (number), test_nbr (number), test_id2 (number).  Test_id column is identified as the primary key and the type of the source already exists a sequence rsn_test_seq.  Column test_id2 gets its default value 0 to a hidden page element.

  I would use my manual process for updating the value of the test_id2 column.  If it's 0 then I want to put the value of the column test_id.  If it is any other value, then it must remain at this value.  My logic works very well for an existing line, but I'm running into a problem with the newly added lines.  The new lines get inserted, but the test_id2 column remains the default value 0.  I can tell the debugger that the SRM process is triggered first and inserts the line, then my manual dealing with fires.  The problem seems to be that the connection variable: TEST_ID for the primary key column remains NULL after insertion.  I don't know how to get the value of the column test_id of my newly created line to use in my PL/SQL block to my update.

  Process of PL/SQL:

  DECLARE
  BEGIN
     :P7_SHOW := NULL;
     :P7_SHOW := NVL(:TEST_ID2,555) || ' and ' || NVL(:TEST_ID,787) || ' and ' || NVL(:TEST_NBR,9999);
     IF :TEST_ID2 = 0 AND :TEST_ID IS NOT NULL THEN
        UPDATE rsn_test
           SET test_id2 = :TEST_ID
         WHERE test_id = :TEST_ID;
     ELSE
        :TEST_ID2 := :TEST_ID2;
     END IF;
  END;

  Any suggestions?

  I have run tests on

  https://apex.Oracle.com/pls/apex/f?p=83488:1 demo/demo

  to see your problem.

  I have 2 solution for your problem.
  I add trial NOT tabular just usual block of PL/SQL

  	BEGIN
  	I'm IN (SELECT TEST_ID FROM RSN_TEST WHERE TEST_ID2 = 0)
  	LOOP
  	UPDATE RSN_TEST
  	SET test_id2 = TEST_ID
  	WHERE test_id = i.TEST_ID;
  	END LOOP;
  	END;

  and works very well, you can see in the sample.

  The other solution is to show new generated TEST_ID

  Adding a sequence as a default value for a column in a table field

  And to execute your procedure.

  I get how is with the good luck of time.

• G530 - how to fix the Novo key features?

  Hello guys!

  Some time ago I completely changed partitions configuration on my laptop, because I wanted to have two systems - Windows 7 (the default) and Ubuntu. Previously, I had an image of the LENOVO_PART (partition Lenovo recovery) by Paragon and burned on DVDs. Its contain images (a recovery key 7) OKR - mbr, boot partition and system (with default settings) file that contains information about the partition sizes and sectors. I deleted all the partitions and create new partitions.

  Now I want to restore the original scores, so I restored the partition recovery DVDs, and I put his ID 12 (PTEDIT32) and rebuilt the other partitions on the accuracy of a sector.

  Now, I have the following partitions: 1 - start (default is unnamed), 2 - system (default is unnamed), 3 - Lenovo, 4 - LENOVO_PART. Unfortunately the Lenovo System Restore does not start once I pressed the Novo key, so I put the active recovery partition and I can't restore the original mbr, boot, and system. Everything would be fine, but the Novo key doesn't work, then press start the normal system of Windows 7, not the recovery system.

  Could someone tell me how could fix the Novo key without the Lenovo service features?

  BTW, sorry for my bad English

  It should work properly. It seems that there is something wrong with the a key.

  at this point, I suggest you call lenovo support line and ship your laptop.
