• How to assign the pl/sql variable to a variable of the page element?

  I want to select count (*) in the emp table.
  
  assign this count (*) total to a pl/sql variable.
  
  How can I assign this varialbe pl/sql variable of page element?
  
  : p2_test = pl_total;
  
  Thank you.

  Good afternoon

  Try this:

  1. create a process Page:
  
Declare
pl_total number;
Begin
select count(*)
into pl_total
from emp_table;
:P2_test := pl_total;
End;


  Or a simpler approach:

  
Begin
select count(1)
into :P2_test
from emp_table;
End;

  If you use count (1) rather that count (*), you do the inventory column 1 and not the entire file. Oracle then reads just column 1 instead of the whole of the record, speed up your query, if the table can have a large number of columns AND a lot of files.

  Good luck

• How to assign the next value in the sequence directly in a variable?

  How to assign the next value in the sequence directly in a variable without using a table TWICE in PL/SQL.

  BluShadow wrote:

  How about a quick test on 11g, just to see if you directly select a sequence in a variable is significantly better than the mark of DOUBLE.

  ...

  Nope... no obvious difference.

  This is because there is none: Oracle's SELECT sequence. NEXTVAL FROM DUAL under the covers. The direct assignment is just a convenient encoding for us, but it does not change the work that accomplishes Oracle.

  create sequence s;
  alter system flush shared_pool;
  declare
  l_num number;
  begin
  l_num := s.nextval;
  end;
  /
  select sql_text from v$sql where parsing_schema_name = user;
  

  SQL_TEXT
  Report the number of l_num; begin l_num: = s.nextval; end;
  Select sql_text from v$ sql where parsing_schema_name = user
  Select double S.NEXTVAL

• How can I get the contents of an object of Document (XMLDOM) in a string variable?

  Hello

  Unlike some other posts, there is a solution.

• TestStand 2012 Newbee question: How do I pass a string to a VI to TestStand to control the flow of sequence?

  I want to use a drop-down list box (or a similar control) in a VI to select from a list of strings to direct execution in TestStand.

  • How connect the channel selected in the combo box at the output of the VI Terminal so I can see it in TestStand?
  
  
  • What should I use as 'value' in the parameter module TestStand to retrieve the result of that VI?

  I tried "wiring" the result of the drop-down list box directly to a terminal of output without success.

  I tried "wiring" the exit from the drop-down list box to a wire string variable then this variable to an output without success Terminal.

  (see attached files)

  Can someone give me an example of a VI that allows you to select from a list of strings: {'Bob', 'Mary', 'Bill', 'Jennifer',...} using a

  (or similar) drop-down list box control and routing of the string selected to the output terminal?

  Also, how to reference this (result) setting within TestStand?

  It is a simple task and there can be only one solution TestStand, I'm looking for a simple direct execution sequence by the operator to select a string in a list.

  I studied this problem, but could not find instances of the digital comparisons or string canned and did not find a generic model that would return a string to a VI to TestStand result.

  Thank you for suffering through this fundamental question.

  Melbourne, Florida

  Marco beat me but here is my interpretation. TS 2010, LV 2011

  Also, look at the example of demo which comes with TestStand: C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 2010 SP1\Examples\Demo\LabVIEW\Computer Test of the motherboard

  Demonstration should be a version of what you want.

  See you soon,.

• Reading local txt file = &gt; string variable?

  Could someone please point me to an example of WebWorks showing how to load the contents of a local (= in the app folder) text file into a string variable? Thank you.

  I assume that by "in the app folder" you mean in the folder bar. If so, he must be a XHR request. I pulled the following from my application.

          var res;
          var xhr = new XMLHttpRequest();
          xhr.onreadystatechange = function() {
              if (xhr.readyState == 4 && xhr.status == 200) {
                  res = xhr.responseText;
              }
          };
          xhr.open("GET",path,0);
          xhr.send();
          // res now contains the contents.
  

• How to create a file name variable with the County and the date?

  Objective: Create a file name variable with the County and the date

  Error: get a lot of error. Do you know how to change my code?

  Question: how to create a file name variable with the County and the date?

  Mini code:

  std::string * rawfilepath;
  std::string * rawfilename;

  rawfilepath = "./shared/documents/";
  RawFileName = rawfilepath + 'rawlog -' + 0 + '-.txt ';
  QFile file (rawfilename);
  If (file.exists ()) {}
  rawfilenamecount ++;
  RawFileName = "./shared/documents/rawlog-" + rawfilenamecount + "-.txt ';
  }

  Thank you for your attention,

  Thank tzander reminding me the idea. Method of cascades is not good for me because all of the kernel code is written by Native. If I change the channel to QString, I need to change a lot of codes.

  Solution is below.

  While (access (rawfilename, F_OK)! = - 1) {}
  rawfilenamecount ++;
  sprintf (format, RawFileName, rawfilenamecount);
  fprintf (stderr, "file exists");
  }

  Rawlog = fopen (rawfilename, "w"); Save the file in a specific path.
  fprintf (rawlog, "System Time (ms)" "");

• [JS, Win/Mac] The Clipboard string variable?

  Hello

  I want to put the contents of a string variable to the system Clipboard. For Mac, it is simple via AppleScript, but how this might work for windows? I searched and read all relevant messages and did some research with google.

  Here is my potion of the code:

  // copy to clipboard
  if ( $.os.toLowerCase().indexOf('mac') >= 0 ) {  
      app.doScript ( 'set the clipboard to item 1 of arguments', ScriptLanguage.applescriptLanguage, [_stringOUT] );  // mac
  } else {
      app.doScript ( 'echo ' + _stringOUT + ' | clip', ScriptLanguage.visualBasic );  // win
  }
  

  One of my friends has tested the Windows part - I work only on a Mac-, but it does not work. Is someone can you please help me understand this?

  Thank you!

  Tobias

  After a long search, I think I finally did:

  _OUT = "Ich bin ein Copy-Paste-Test.";
  if ( $.os.toLowerCase().indexOf('mac') >= 0 ) {  // widows to clipboard
      app.doScript ( 'set the clipboard to item 1 of arguments', ScriptLanguage.applescriptLanguage, [_OUT] );  // mac
  } else {
      app.doScript ( 'Dim theObject\r Set theObject = CreateObject (\"htmlfile\")\r Call theObject.ParentWindow.ClipboardData.SetData(\"text\",\"'+_OUT+'\")', ScriptLanguage.visualBasic );  // win
  }
  

  Can someone please test this piece of code on a windows machine?

  Thank you!

• How to assign the value to the application-level element

  Hello

  I'm learning to APEX.  I use version 4.2.6.

  My question is, I set a text field called 'FINANCIAL_YEAR' in the login page.  I wanted to know how to assign this value to a text element of Application level (on page sent), so that I can get this value through at my request.

  Thank you

  Yes, I created a 'text area' under 'HTML' in the 'Home' page  Who accepts the exercise of a table through LOV.  I intend to assign this value to a global variable so that this variable can be read in any of the application to filter the result set from different tables (not yet built the rest of the application).  To do this, I was intending to use "Shared components"-> "Elements of Application".  I'm still not quite sure how it works.

  Start by reading the documentation on elements of application.

  Go to the shared components > Application parts and create your G_FINANCIAL_YEAR item. Value Session State Protection Restricted - can not be set the browser so that the value is not editable by the user, falsification of URLS or scripts.

  On the home page, if there is not already a button to submit the value of the fiscal year, add one in the HTML area, with the Action as a submit Pageclick. Otherwise, you can do without the button and using submit Page in Page Action when the changed value select the parameter in the list so he can undergo.

  Then, in the section of the Page processing, create a calculation:

  Point Type: Application-level element

  Calculate Item: Application: G_FINANCIAL_YEAR

  Point calculation: After submit

  Type of calculation: Value of the element

  Calculation:

  Run the application, select a value in the list of the fiscal year and submit the page. Review of current session state in the viewer of session state by clicking on the link of Session in the toolbar developer. Select the Elements of Application in the view list, and then click set. The element of your application and its current value must be visible. You can now reference value throughout your application by using the appropriate syntax.

  You should also consider if a default value (for example the current year) using a calculation Application from the point of calculation on the new Instance and coordinate the application point and part of the homepage using point application as the Source of value or an expression with Source page element, the value always, replacement of value that exists in the session state.
