[ORACLE 9] OPEN for the variable binding USING declaration

Hello

I have a loop that retrieves only 1 sheet instead of 7:
DECLARE

 lv_into varchar2(40);
 lv_qry  varchar2(400);
 
 type curtest_ref is ref cursor;
 
 curtest          curtest_ref;
 lv_compteur number(4) := 1;
 
 lv_client_loc   varchar2(100);
 BEGIN
 dbms_output.put_line( 'Début' );
 lv_qry := 'select client_loc from tmp_jbm where client_id = :A ';
 
 open curtest for lv_qry using lv_compteur;                 
 loop
                fetch curtest into lv_client_loc ;
                exit when curtest%notfound;
                dbms_output.put_line( 'ligne: '       || to_char( lv_compteur )
                                   || ' Client Loc: ' || lv_client_loc );
                lv_compteur := lv_compteur + 1;
                exit when lv_compteur > 6;
     end loop;
EXCEPTION
    when others then
             dbms_output.put_line( 'Erreur exception: ' || sqlerrm );
END; 
[/END CODE]

It looks like the cursor only fetches 1 record and then stops.

Many thanks                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        

Bind variables are evaluated when the cursor is opened. Not when extract you the data.
I don't know why you use dynamic sql, here, you do not need.
In any case, your code is incorrect.
Assuming that the client_id is unique, Yes, your fetch fetch one line. When you loop the second time, retrieving a new record for the same statement, then you hit no_data_found.

    Hi, sorry for the unclear post, it's 11 GR 2.

    As Sybrand already mentioned, there are a lot of change that came in the implementation of the bind variable in some versions of Oracle db. Since you're on 112, it is still true with the introduction of Adaptive Cursor Sharing . Please have a read on it since the post below written by the development of Oracle optimizer group.

  • Use sessionScope as the value of the Variable binding

    Dear all,

    I have a variable in sessionScope, and I want to use it as a condition of application of a ViewObject.

    I found a thread talking about, there's only one: (Re: set the value in the global variable. )
    How to use the value in the scope of session groovy script?

    Model project:
    Set variable in the scope of the session:
    ADFContext.getCurrent () .getSessionScope () .put ("Empno", empno);

    Getting value of session scope:
    Object empno is ADFContext.getCurrent () .getSessionScope () .get ("Empno");.

    ViewProject:
    Set variable in the scope of the session:
    FacesContext.getCurrentInstance () .getExternalContext () .getSessionMap () .put ("Empno", empno);

    Getting value of session scope:
    Object empno is FacesContext.getCurrentInstance () .getExternalContext () .getSessionMap () .get ("Empno");.

    Getting value of scope jspx page session
    #{sessionScope.Empno}

    Hi Samson,.

    Here are the groovy expression to access the value of the sessionscope:

    adf.context.sessionScope.role
    

    But, as the said John instead to access the session of the model can be a method of model (whether in AMImpl or voImpl) who takes the role as a parameter value and sets the value of the variable binding of the vo, then call this AM from the bean method passing the role value by getting the scope of the session.

  • Impossible to retrieve the password for the user FUSION_APPS_WSM_APPID using ldapsearch

    Kind regards

    Vinayak K

    Can you clarify why you need recover the password? Application identities are designed for internal processing and never to be exposed outdoors or used for other purposes only lift access to the code in some scenarios within the system. So only the administrator must have access to the account and the password of access they would reset it in the store of credentials if necessary. That said I think that the admin can retrieve the password using the command listCred wlst something like:

    listCred(map="oracle.wsm.security",key="FUSION_APPS_WSM_APPID-KEY")

    Hello

    You could just add links to each box, but a better solution would be to use svg for this. Unfortunately, it is easier for me to write for someone who does not know svg to do.

    If you have Adobe Illustrator create your svg using this program, then it would be a case to add links manually to each box created in the svg code. SVG is an xml-based language and not a real image, even if this is how a browser will display the it.

  • Coloration of the code for the PHP files using CSS

    Coloration of the code for the PHP files using CSS

    The Situation:

    It is possible to mix PHP and CSS so that you create a PHP file and it is served to the user in a CSS file. It works just like writing a normal PHP file which is then processed and used in HTML. To do this, you create a PHP file and at the top of the file, you add the following line of code:

    <?php header("Content-type: text/css"); ?>

    This line tells the browser that the file is CSS instead of HTML. Fantastic.

    Here is a link to a more detailed article on the subject: http://www.barelyfitz.com/projects/csscolor/

    The problem:

    The problem is that when I create a PHP file in Dreamweaver code colors in the document like PHP for PHP and HTML to CSS code code because it still thinks the document is supposed to be a HTML document. Is there a way to change the style of this situation? I find that code coloring to normal CSS files is really useful and would like to be there instead of just black text.

    Other information:

    I already have this submitted a feature request to Adobe, but I never heard back. Does anyone know how to do this now?

    I would really like to see the code coloring to adapt to the content type of the file, when the file is PHP. So if no content type is specified, values by default in html format, but when it's CSS, code coloring so a coloration of the different code is used. It could also adapt to files JS, XML files, the works. But really, I just want to add the PHP/CSS code coloring.

    I'm certainly not an expert, and this is my first time looking at the file,

    but it looks like the section.

    "ID ="CSS"doctypes ="CSS"priority '50' = > ' see the style css and

    the and refer to where the design must

    be applied. If that is correct then the code you provided should style

    It all starts after the

    and ending with another php code? It should be then that a

    tag additional php to be present in the document of 'close' the

    blowdry.

    And the continuation of this line of thinking, I have just that in the (php-> css)

    file. I placed my code. Then

    After the CSS, I placed another block of php: and it works!

    The CSS is styling just like should the CSS.

    Logically, you need that, and it seems to work ok for me without it. If Yes, you can change "" to be more explicit and less impact for PHP parsing, such as ' /DW/ '.

    Haha, Unfortunantely, PHP is more the same color scheme. He

    went from normal red blends what the html code looks like

    scheme (blue with quotations from green text). Fortunantely this configuration is far

    more convenient than the previous color coding!

    All subsequent PHP Directives are coloring properly for me - it's just the first one that triggers the coloration (e.g. ) is not. What do you see?

    If, therefore, in the XML file you added in CodeColoring.xml, you can change:

    scheme = "outerTag.

    is similar to the colouring of the PHP Directive:

    scheme = "customText" id = "CodeColor_PHPScriptBlock".

    This causes the entire PHP directive is red color - not optimal, but a little better.

    Here the implicit conversion does not work, and '3.4' is considered a stgring rather 2 separate values. I have to have to use bind variable and do not want to use dbms_sql. Is it possible, '3,4' is taken as 2-digit values, rather a string value helps Pl, thanks.

    You cannot use list as a bind variable. Use:

    SQL> create or replace PROCEDURE get_data (p_data IN OUT SYS_REFCURSOR,
      2  p_id IN varchar2)
      3  is
      4  sql_str varchar2(100) := 'SELECT * FROM tab WHERE tab.X IN (' || p_id || ')';
      5  begin
      6  open p_data
      7  for sql_str;
      8  end;
      9  /
    
    Procedure created.
    
    SQL> SET SERVEROUTPUT ON
    SQL>
    SQL> VAR A REFCURSOR

             4 rr
    
    SQL> 
    

    Or, if you want to use bind variable, use the composite type. Something like:

    SQL> create or replace
      2    type NumberList
      3      as table of number
      4  /
    
    Type created.

    This is the way of declaring bind variables in SQL * more.

    In a PL/SQL block, you do not use bind variables like SQL * more. You just use normal variables. The PL/SQL engine is smart and sends SQL statements to the SQL engine containing all PL/SQL variables converted to bind variables. If it works transparent in PL/SQL and you don't have to do something more.

    How to open 2 e-mail accounts at the same time?

    Hello carroll12,

    Thank you for using communities of Apple Support.

    I see that you do not want to open two e-mail accounts at the same time using the Mail application. I understand perfectly. I have multiple e-mail accounts set up in my Mail application. I'm happy to help you with this.

    You can have more than one e-mail account set up in the Mail application. The first time you open Mail, it may prompt you to add an e-mail account (if you have not already done). Select an account type, and then enter your account information. To add another account, choose Mail > add an account, select an account type, and then enter your account information. Make sure that the Mail check box is selected for the account.

    If you have already both set in place, and I just want to be able to view both on the screen at the same time, open Mail, and then click file at the top.  From there, select the option for the new window of the observer.  This will open a new window where you can see each of the individual mailboxes on the same screen.

    Have an amazing day!
