  Concerning
  Rambeau.

  I think the problem is the line:

  execute immediate l_str into l_column_value;
  

  run immediately makes does not work with the clob type. You must define the variable l_str as type varchar2.

  Another problem, it's your last line:

  return 'select l_ret_str from dual';
  

  You will always return the text "select l_ret_str from" dual I can't believe that's what you want. Probably you want:

  return l_ret_str;
  

  I suggest to also qualify the variable l_ret_str of type varchar2.

• Create Bluetooth earpiece function only works in some cases

  The function create a listener Bluetooth generates an ID of listener that lets wait for an incoming connection of Bluetooth. Because every time that you run a VI that contains this function, it must create a new listener ID, otherwise the block following that wait on the listener will crash.

  I found that for the listener to create function work properly the entry that the Service Description must be connected to a control element. If its connected to a constant run only once, then creating a new id of the listener, but she keep this id indefinitely. In this case, you will need to close all the screws and reopen to be able to run the function again.

  (See attached VI for an example.)

  Can someone tell me, why is this? Is there a difference in the compilation/execution screw using controls instead of constants?

  Thank you!

  I could reproduce the error. I presented a report to R & D. I'll let you know when I get a response from them.

  For now, you can try using a control instead of a constant and make it invisible in the façade.

  Kind regards

  the answer lies in a few cases only,

  The response illustrates the basic concept of how customers need to use cursors created using PL/SQL as a layer of abstraction - SQL and this concepts adapts to ALL cases where the customer wants to Oracle via PL/SQL cursor.

  a case is,
  If my function returns only a single value, then I can use oracle 'create function' with the return type as types predefined as a whole, varchar2 etc?
  with regard to performance.

  With regard to this performance problem? And why now suddenly change the question to want to use a function to return data type number or string? How does this relate to PL/SQL to return a cursor now?

  A function can return scalar values, not scalar. A function may return atomic values (such as a unique number, or a non-scalar list of numbers). A function can return a complex data structure consisting of scalar values, not scalar.

  However, in PL/SQL function must NOT be used to read the lines of the database to cache lines in a memory of the server PL/SQL (PGA), then back to the client.

  He does not. It does not fit. It is too bloody dangerous to the overall health of the server as such code plays silly blighters with very expensive server memory.

  A PL/SQL function can also be used as guideline, returning data via expensive PGA, but via the SQL engine instead and using its slider interface (which allows output data to be "gradual" and not to return all data with a single copy of croustilleur mass of the call stack) directly. IT IS, HOWEVER, AN EXCEPTION. There is very rarely the need to make the functions PL/SQL pipeline table - and is often victims of abuse and bad demonstrated with examples of absurd code here.

• How to record various objects used by an external C function

  I want to do my own LV component that calls a C function that uses an external API. For the first time, my function is called, it creates and defines variables and some API objects and store them. If the future my function calls do not need to define and create them again. The main problem is that this variables and objects must be different for any instance. I mean: if I have several components to call a library function, the call to my function, running at the same time, I need them to create variables and objects, instead of sharing their own API. So I need to be able to access or to allocate a memory space for each different instance of the NSI component that calls to my function.

  How can I do this with the function of library call? Is there another approach to this? How?

  Thank you very much.

  OK, I really appreciate this answer, thank you very much.

  Of course, I understand that I need to create a function which deletes, clean, free, etc., all objects and the variables created. But I don't know where exactly call to clean up at the right time. I want to have cleaned up the Labview runtime stops (do not break)... so do I call it as a reminder of the library call feature? Anywhere else? Another option?

  Thank you very much!

  Well in general, you flow "create(), read() read(2)/write(2) () / () use, close() in an application" for any resource and close() would be where you would have to call your function has.

  If you want this fact automatically, half only officially documented way is indeed the named of the dialog configuration node unaptly callback function call library. How is this registrant one or more additional function that takes a pointer as a parameter value. This pointer can be everything you want it to be, and you can configure your function to have an additional parameter which is not exposed on the diagram, but rather helps him pass this pointer.

  LabVIEW maintains such a pointer dataspace CLN instance and calls the callback function that appropriate specified events and pass this pointer to data. For example, you can check in the call to the create function if this parameter is NULL, and if yes to store a handle to your resource in there. When the reminder cancel or abort is called you could go and own up to your resource.

• ActionBar.placement changes create duplicates

  I want to create functionality that my app is purchased the action point happen OT InOverflow OnBar however the following code creates doublonnait followed when it changes.  Any suggestions how to get around this problem?

  {ActionItem}
  Title: qsTr ("Options")
  ActionBar.placement: _tiledApp.purchased! 'Bought = '? ActionBarPlacement.OnBar: ActionBarPlacement.InOverflow
  onTriggered: {}
  If (_tiledApp.purchased == 'Bought') {}
  If {(sold)

  Console.Debug ("pushing retail" + page)
  navPaneid.push (page);
  } else {}

  Console.Debug (purched);
  }
  }
  attachedObjects:]
  {SystemToast}
  ID: optionsToast
  body: 'Premium Version required.
  }
  ]
  },

  I'll post this as a bug - leaving however the actionitem in place and simply change the title, image and function is a workaround that works - as long as you are swapping onBar and inOverflow.

• 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
  Gaurav R

  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
