  If you use NOCOPY in the parameter, then the value will be applied directly to the variable of output as it get set to so it will not be lost when the exception occurs. So, of course, to capture the exception or anything to access your dbms_output statement, but it is trivial...

  My problem is that I get the value upon registration of the sequence and not the value after execution.

  How?

  Vagn,

  in order to obtain the values of the execution, you need access to execution. The following screenshot shows how to access.

  

  Please note that this VI is lying will be called by TestStand. DO NOT USE THIS VI IN A CUSTOM USER INTERFACE!

  Hello

  You must run programmatically run the method binding. If I'm not wrong then the following code will allow you to access the return value

  OperationBinding oper = bindings.get("MyPLSQLAccessMethodBinding") (OperationBinding);
  String returnValue = oper.execute ((String));

  Once you have the string in a managed bean you can add it to the stack of messages JSF exposed by the FacesContext

• How to get the return value in sqlplus to index?

  Hello
  
  I am a PL/SQL Developer, and I have a problem with an existing batch.
  
  Here's the situation:
  I have a lot of unix, calling a first script sql with sqlplus (call script0.sql )
  script0. SQL call other scripts sql with the command @ (script1.sql, script2.sql,... = > scriptx.sql )
  My version of sqlplus is 9.2.
  
  ScriptX.SQL modifies the data in table with insert or update and not commit or rollback anything (it is in charge of script0.sql ).
  If there is an error produced in a clue all changes must be rollbacked.
  Unfortunately when something fails, it returns only to script0.sql without any information on his breaks down, so continuous script0.sql and when he arrivals all changes are committed because the State of script0.sql is successful when the exit is made.
  
  Is there an equivalent of the $? UNIX in sqlplus to obtain the return of a status @scriptx.sql?
  
  -----
  Here is the general syntax of the script0.sql :
  
  WHENEVER SQLERROR EXIT 99;

  Use: 'every time THAT SQLERROR EXIT DISMANTLING', if you want to there are a whole script error
  OR "WHEN SQLERROR CONTINUE ROLLBACK", if you want to restore and continue to the next.
  You might explore other options 'whenever SQLERROR WHAT' to suit your logic and add "COMMIT / ROLLBACK" to not relevant.

• How to get the reference or the property of a member in OOP node?

  Hello world

  Is it possible to get the referral of a member in OOP?

  After you have created a class and an insert, a member of control in the cluster, I conclude that, when a right click on it, there is no element of "creat-> reference" or "create-> property node?

  So, how to get the reference or the property of a member in OOP node?

  Hello

  There are a few reasons that you can't do what you want to do:

  1 al ' LVOOP ordinary (as opposed to the DVRS in LabVIEW 2009, or some other framework / pattern design) are items of LabVIEW by value, as a cluster and therefore you can not create a reference to a class.

  2. a control of the object (this is what you get when you drop an object on a façade) is a 'black box' because you cannot look inside. This is to support the idea that the class data private. This means that you can't get a reference to all internal control when its on a façade

  3. check the references are valid only for the controls in the Panel before and therefore any class (or other piece of data of LabVIEW) on a wire / shift register / constant / anywhere other that of the façade, will have only the data portion of the available control.

  To access the items within a class, you create the accessor screws (you can create them easily by right-clicking a class (or the folder within the class) in the project tree and selecting New-> VI to access data members.) This VI would at least have a unbundle / bundle node (depending on whether its read/write) and could, if you have many more features such as range checking. You can use this VI whenever you want to read the Member your interested.

  I hope this helps.

• How to get the Subvi (the virtual path is in .exe) reference in Run Time System

  Hello world

  The problem is how to get the reference of the Sub - VI in run time system, when the Subvi is in .exe after construction.

  More details:

  Top of page vi called the Subvi dynamically, so that the Subvi is always included, and the source object is the application.exe.

  After the above configuration, the Sub - VI will be the application.exe. For example, the path of Subvi est...\application.exe\SubVI.vi

  So, how to get the reference of the Subvi in Run Time System?

  I can't do it when you use 'open reference VI' with le...\application.exe\SubVI.vi path in the run time system.

  In fact, I can create a file to include the Subvi, rather than build the Subvi in application.exe, then I can get the convenintly reference. But this isn't my favourate average.

  Thank you

  chenyin

  That is the problem. Call a Subvi dynamic means users could change, but it is also very attractive.

  The dynamic call should be used in a user control, but some parade can avoid problems.

  It depends on why you use dynamic calls...-online 2 main ways:

  -Dynamic call are used to maintain a scalable framework for the code without acting on the executable file-online a single VI distribution managed by the administrator/developer

  -Dynamic call are used to provide a collection of "external" characteristic that could be enriched by the administrator/developer. For example, you provide your customers a set of selectable custom signal filters in the executable.

  In 2 cases, you are only able to assess the skills of the users to know if there is a risk of damage, if there is a change.

  So to stay only master a parade might be to provide dynamic VI without a schema, but with the problem of maintenance, since no in-place editing and more attention to manage distribution.

  Another way is to hide the actual distribution to user-online call dynamic VI but it without name as *.vi but others (a repellent name as system of OS name ) or simply without extension in order to attract not user... but that's debatable...

  Another more difficult but more secure method is to create a consistency check before your routine (version, user, modified date,...)

• How to get a reference to the delivery of the program (not at base of LV)?

  Hello

  I need to create a LV application which will be:

  -Run external executable and not on LV. It has a window of the UI which will open

  -Open PS (no title, menus, etc.) and position it under the user interface

  -If the user moves main UI, LV app FP follows the window

  -If the user closes the main user interface, LV app closes and ends.

  App - LV does not display in the bar of tasks

  So, basically, I need to develop an application that will add-on to an existing GUI, so that together they look and behave like a single user interface.

  The main thing I am struggling with now is how to get a reference to the execution of UI that I call using the exec.vi system
