  Can I change the query1 query for plan2?

  As Juliet was mentioned in the first SQL that you generate from the ENAME list that you must pass in the IN clause when executing. But in the second SQL, it passed as a static value. So first SQL must do more work. So you see a different execution plan.

  But this is a work around to get what you are looking for. But I can't say it's a foolproof method. But anyway here you go.

  SQL > var ename_list varchar2 (100)
  SQL > exec: ename_list: = 'SMITH, ALLEN, WARD, JONES ';

  PL/SQL procedure successfully completed.

• How to extract the value of the element as an array in javascript

  Hi all
  
  I want to do some calculations on the value entered by the user in the textfield of a tabular presentation, how can I retrieve the value of the element as an array in javascript?
  
  I use as a normal, do not use in the form of apex_item.
  
  I can pass the current value of the textfield to the function using 'this' as a parameter, but how can I retrieve the value of other lines of the same column?
  
  Thank you

  If it is a page element wouldn't be better to make a calculation of point page when onload of the page? Just do a SQL as select sum (col1) of dual nationality or whatever is your table/column?

  Use Back-referencing to extract all the secondary channels of a particular model:

  Ranit>> with xx as(
    2       select '12345678978979798ZXC3ASD456FGH8TED63456789123' x from dual

  @NSK - what will happen if a 3 ^ rd ^ substring exists? You have hardcoded for 2 SUBSTRs.

• Verification of an element in one string from another string

  Hi guru,.
  
  I have 2 strings separated by commas. Say it like that.

  Kindly help me.

  Hello

  I'd probably use the Michaels, but if you want to see how you could do this using regular expressions:

  SELECT     *
  FROM     table_x
  WHERE     REGEXP_LIKE ( ',' || a || ','     || '/' ||
                  ',' || b || ','
                , '(,[^,]+,).*/.*\1'
                )
  ;
  

  where "/" is known not either a or b.

• 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.

• 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.

• How to extract string in JSON data where the value in a table

  Hello

  Structure of JSON string

  {'name': 'John', 'name': 'kumar', 'address': [{'Address1': 'value', 'place': 'value'}, {'address2': 'value', 'place': 'value'}]}

   

  
  How to extract the value of the address of the list.

  If you have control over the format of data, it is best to rename address1 and address2 to have the same name, for example "address". Then, it can be analyzed that way (I've also simplified other code a bit):

  JsonDataAccess jda;
  QVariant v = jda.loadFromBuffer(jsonString);
  QVariantMap m = v.toMap();
  QString name = m["name"].toString();
  QString surname = m["surname"].toString();
  QVariantList addresses = m["address"].toList();
  foreach (QVariant addr, addresses)
  {  QVariantMap addrMap = addr.toMap();
    QString addressValue = addrMap["address"].toString();
    QString place = addrMap["place"].toString();
  }

• How to extract files from the Windows 7 installation CD?

  I remember that on Win98, I can use SFC. EXE to extract all those files. CAB files on the installation of Win98 CD and place the files extracted into a folder I want. In addition, I don't need to know where. CAB of the target file should be some.

  The SFC. EXE in Win7 replces only system files. It does not extract and put all the files as the SFC in Win98.

  So, how to extract files from Windows 7 installation CD?

  Hello

  ·         Why you want to extract the file from the Windows 7 DVD?

  Some of the files will be locked or currently in use by the system so that you will not be able to replace their while that started in Windows 7. Therefore, SFC scan tool is used to repair any file corruption in windows 7.
