• By the way Self as a parameter or by passing an object Variable to a member function, both in the approach IN OUT NOCOPY Mode which is better?

  Hi all
  Asking for help which approach is better of the two in terms of performance and why (if there is no difference) or are they an and they same and only different in terms of syntax only.

  (A) to call a function with itself in passing as IN OUT nocopy
  (B) passing the calling object, same as IN OUT NOCOPY.

  @
  (In my approach, I need to pass an object with almost 30 attributes and I must assign values to few attributes of the object in a few member functions that will impact object)

  I have an object created in the
  CREATE or REPLACE TYPE my_obj AS OBJECT
  (
  NAME VARCHAR2 (100),
  FUNCTION CONSTRUCTOR My_obj RETURNS SELF AS RESULTS,
  FUNCTION MEMBER put_name (SELF IN OUT NOCOPY my_obj) RETURN PLS_INTEGER,
  RETURN of the MEMBER FUNCTION insert_name (v_my_obj IN OUT NOCOPY my_obj)
  PLS_INTEGER,
  MEMBER get_name PROCEDURE
  );
  /
  CREATE OR REPLACE TYPE BODY MY_OBJ

  FUNCTION CONSTRUCTOR RETURN self AS RESULT My_obj IS
  BEGIN
  NULL;
  RETURN;
  END;

  FUNCTION MEMBER (SELF IN OUT NOCOPY my_obj) put_name IS BACK PLS_INTEGER
  BEGIN
  Self.Name: = "my_name_in_self";
  RETURN 1;
  END put_name;

  MEMBER FUNCTION insert_name (v_my_obj IN OUT NOCOPY my_obj)
  IS BACK PLS_INTEGER
  BEGIN
  v_my_obj. Name: = "my_name_in_Alias";
  RETURN 1;
  END insert_name;

  MEMBER get_name PROCEDURE IS
  BEGIN
  dbms_output.put_line (self. (Name)
  END;
  END;
  /

  (a) put_name heel 1 call:

  declare
  v my_obj: = my_obj();
  number of ret_val;
  Start
  ret_val: = v.put_name;
  v.get_Name;
  end;

  o/p: my_name_in_self

  (a) insert_name citing heel 2:

  declare
  v my_obj: = my_obj();
  number of ret_val;
  Start
  ret_val: = v.insert_name (v);
  v.get_Name;
  end;

  o/p: my_name_in_Alias

  What is better to use the put_name or use the function insert_name.
  I manipulate the object when it is passed to a function.

  Thanks in advance,
  Kind regards

  As Billy said above, each member method has implicitly (which can be made explicit, as with "put_name", when required, for example, to specify the "nocopy" option) parameter named 'home '. For member functions, the passage of default mode is "inside". For the procedures of members, the passage of default mode is "outside". Therefore, the actual signature of the function of your 'insert_name":

  ...
  member function insert_name(self in my_obj, v_my_obj in out nocopy my_obj) return pls_integer
  ...
  

  Since you don't self directly access this function, it is logically equivalent to a static type function (which has no implicit setting of "self"):

  ...
  static function insert_name(v_my_obj in out nocopy my_obj) return pls_integer
  ...
  

  which is basically no different than using a non-object function that takes a parameter of type of object:

  create function insert_name(v_my_obj in out nocopy my_obj) return pls_integer

• by the way the date in url parameter criteria

  Hello
  
  I want to filter a recordset before a certain date.
  Create the Recordset, if I use a value of execution of 27 November 06 # all records for this date are returned.
  However, when I try to spend the same information through the URL parameter it does not work.
  
  Is there a problem with this info by the way like this?
  
  Thank you, Mark.

  Not to be absoloutely fine. The problem is most likely to do with your SQL
  statement.

  A test are not all records. At the top of your page, try
  output from the SQL statement finished on the page to see what it looks like
  as. The problem is, you may need to add the symbols # manually. Expected
  look like

  "SELECT * FROM TableName WHERE DateField = #" & URLParameter & "#".

• By the way the record as a parameter type to function

  Hi all

  I tried the below the example query for the record type as IN parameter works and I confused when calling the function.

  Please find the code below

  create or replace package pkg_rec is

  type t_rec record is (ename, sal emp.sal%type emp.ename%type);

  end;

  create or replace function get_emp_sal (emprec pkg_rec.t_rec)

  number is back

  v_empno emp.empno%type;

  Start

  Select empno in v_empno

  WCP

  where ename = emprec.ename and sal = emprec.sal;

  Return v_empno;

  end;

  -Block to call the function

  declare

  v_rec pkg_rec.t_rec;

  v_empno emp.empno%type;

  Start

  v_rec. Ename: = 'SCOTT ';

  v_rec. SAL: = 3000;

  v_empno: = get_emp_det (v_rec); -Get the error "Expression is of the wrong type."

  DBMS_OUTPUT. Put_line (' values ' | v_empno);

  end;

  You can please me to pass the parameter to function; referring

  Thank you very much.

  Is it typo?

  Your function is called get_emp_sal, but you call get_emp_det.

• Set the string for LabView dll parameter

  Hello

  I created a simple vi LV 2010 (departure vi), which reads the identification of an oscilloscope. Then I take this vi and incorporate it into a dll of LabView. I have test the dll calling LabView (RunFrom dll). Basically, it seems to work, but len and ReadBuffer back empty. It must be in the way I'm configuration configuring the setting for Readbuffer (settings) in the configuration of the dll. I tried several different configurations, but nothing seems to work. Any help is appreciated!

  What is the parameter len?  Normally, you should only set the length of the string, but it seems that you did not do this.  Also, you're passing len by value, and not by reference, so the function is expecting her to be a starter and you will never get return a different value to any value that you provide.

  Do not use a local variable of the ReadBuffer for entry "readbuffer".  You must pass a string initialized long enough to contain the expected quantity of data.  The best way to proceed is to use the array to initialize to create a table of U8, then use the array of bytes to a string.  Set the parameter 'minimum size' to 'len' then run through the length of the string initialized (this is not mandatory but is recommended).  If you need the length obtained output, add another indicator and another parameter to this value.  There might be a way to do it with one by len parameter passing by reference, you need to experiment (it is certainly feasible in C but I don't know if allows him to LabVIEW).

• I was entering numbers in a table of existing pages and suddenly the formatting has changed and I can't type numbers the way I need too.  How to fix this?

  I was entering numbers in a chart in Pages to update the information and all of a sudden the cells do not have the formatting that I want.  It's changing the way numbers which I type them, and I don't know why or what to do?

  Hi Slf@LF,

  Numbers and pages are trying to be smart and recognize wht kind of data that you enter. If you enter something that resembles a date they will treat it as such. Some people have problems with serial numbers because programs to format their numbers and not text.

  View the data that you are trying to enter and how it's changed and we ca probably to understand what is happening to her.

• In one of my firefox browser, the header/footer margin setup parameter is inches, I need to change it to milimeter to inches. Your help is appreciated.

  In one of my firefox browser, the header/footer margin setup parameter is inches, I need to change it to milimeter to inches. Your help is appreciated.

  As far as I KNOW Firefox displays the metric or Imperial depending on the type of paper selected for printing. If you are using A4, you should get millimeters/metric.

• Am I able to configure a wireless iMac keyboard to emulate the way a Windows keyboard responds to a depression of the DELETE keys and BACKSPACE?

  Am I able to configure a wireless iMac keyboard to emulate the way a Windows keyboard responds to a depression of the DELETE keys and BACKSPACE? I want to delete either to the left right GOLD of the cursor. By pressing the DELETE key on Mac does remove one way, but I want the ability to delete in both directions. The Windows keyboard provides a delete key to remove to the right and a key to return back to remove to the left. So I can configure an iMac for this keyboard? My thought is to keep the delete key as it is and ADD a new function to one of the function keys to delete characters to the left. Thanks for your time and your help.

  Mac can go both ways, in case this is useful.  You can use fn more delete to delete to the right.  Also control more.

• my computer shuts down about 2/3 of the way after that the progress indicator starts and stops... any suggestion as it turns on again?

  Start Safe Mode removes the system caches that can help.

  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 logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

  Then try to update iTunes.

• You can change the way that you scroll up and down pages.have just installed the new update from apple and the way in which you have to scroll through the pages in firefox has c

  After you have installed the latest version of the software update apple has changed the way you scroll through the pages. I would like to consider to have a box at the top and bottom of the screen that you use for scrolling. Any help would be greatly appreciated.

  On Mac, scroll bars may be hidden and are showing them when you scroll down the page, so you can see the current scroll position.

  The idea is that a Tablet is used that does not need to be visible and therefore more screen real estate for the navigation area, scroll bars.

  You can make scroll bars always appear:

  System Preferences > General > Show Scroll Bar > Choose "Always"
