• Avoid calling the procedure in the cursor loop

  Hi all
  
  The following example of procedure the procedure written in cursor loop, is called each time until the end of the cursor loop...

  procedure proc_main is
  DECLARE
   cursor c1 is 
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
   
  BEGIN
    for i in c1 LOOP
     proc_test(i.empno,i.ename,i.dname,i.loc) ;
     end loop;
  END;
  -----------
  
  PROCEDURE proc_test (p_empno,p_ename,p_dname,p_loc) is
  ---
  ---
  begin
   select * into v1,v2,v3 ..
    from temp_tab
     where col1 =p_empno
      ----
      ----
  
  end;

  What would be the alternative methods to write the procedure above instead to call the procedure inside the cursor for loop
  My idea is to use collections... could you give me the code example using collections to meet the above criteria
  
  Thank you

  The ideal would be to collect all SQL logic and put as much of it in a single SQL statement as possible. It would be also great to determine what is the final outcome of the process and use it as a starting point for your SQL. For example, if the desired result is to upgrade the salaries of the employees where they have an entry in table x, you might find that you can avoid needing to separate the logic between multiple, i.e. instead of procedures

  procedure proc_main is
  DECLARE
   cursor c1 is
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
  
  BEGIN
    for i in c1 LOOP
     proc_test(i.empno,i.ename,i.dname,i.loc) ;
     end loop;
  END;
  -----------
  
  PROCEDURE proc_test (p_empno,p_ename,p_dname,p_loc) is
  ---
  ---
  begin
   select * into v1,v2,v3 ..
    from temp_tab
     where col1 =p_empno
      ----
      ----
  
      UPDATE
          emp e
      SET
          sal = v2
      WHERE
          e.empno = p_Empno;
  
  end;
  

  You may simply have

  procedure proc_main is
  BEGIN
  
      UPDATE
          emp e
      SET
          sal = ( SELECT
                      t.new_sal
                  FROM
                      temp_tab t
                  WHERE
                      t.empno = e.empno
                 )
      WHERE
          EXISTS
              (   SELECT
                      NULL
                  FROM
                      temp_tab t
                  WHERE
                      t.empno = e.empno
              );
  
  END;
  

  Even if your logic is more complex, you are likely to find that you can merge several of the statements that you could be running in a loop and replace that loop with a join.

  Given the particular structure of what you posted if, instead of calling the procedure in a loop, you can simply move the cursor c1 as a parameter to proc_test that is

  procedure proc_main is
  
      lc_c1   sys_refcursor;
  
  BEGIN
  
      OPEN lc_c1 FOR
      select e.empno empno
             ,e.ename ename
             ,d.dname dname
             ,d.loc   loc
      from emp e,dept d
      where e.deptno = d.deptno ;
  
     proc_test(c1) ;
  
  END;
  -----------
  
  PROCEDURE proc_test (p_Cursor sys_refcursor) is
  
  begin
  
      LOOP
          FETCH ....
  
          ...DO SOMETHING...
  
          EXIT WHEN p_Cursor%NOTFOUND;
  
      END LOOP;
  
      CLOSE p_Cursor;
  END;
  

  But I highly recommend that you consider trying to merge as much of your SQL before considering the approach of cursor.

• ORA-06508, procedure cannot call the procedure of package

  I have a large stored procedure that calls a package (procedure) that manages a number of procedures to determine whether the process can continue or not.  (It checks authorization of the student to enroll in a class).  We have a web process calling the stored procedure, and that works fine.  What does not work, is a call to the package.  Oracle returned ORA-06508: PL? SQL: could not find program unit called.

  I have included instructions for debugging, so I know that it is the specific call to a procedure in the package fails with ORA-06508.  Thinking it's perhaps something in the package, I inserted a debug statement as the first line in the procedure called in the package.    (Debugging instructions call a procedure inserts of rows in a table of debugging with independent validation).

  When I log in the user account with sqlplus and run a test, everything works fine.  But when the web process is running under the same user, the process fails to call the procedure of package and fails with ORA-06508.

  It seems as if the web process runs with the rights of the appellant, or a role is not granted.

  Can someone help me understand what the problem is?

  offered hv, I appreciate your comments.

  We solved the problem: remove the package that couldn't be cited, then re-create.   That's all!

  Apparently, something in the database was tangled upward.   The server recently had problems with disk space, then it might have been related to that.  But we'll never know for sure.

  The stored procedure and packaging (procedures) which he called were owned by the same schema, and there is no mechanism that I can find to prevent one of the other appellant.  But that was the case - Oracle threw the ORA-06508 exception when the stored procedure called the package procedure.

  I replaced the stored procedure and package several times fine-tuning debugging code, but this has not fixed the problem.

  Finally let it drop and then re-create the package, it's which solved the problem.

  Regarding requests to view the code, there is no way that I could reproduce the problem, since the error that occurred was against the permissions and rules which packages run and the procedures of the Oracle.  Thanks for all the tips and suggestions.

• Can we call the procedure inside the function?

  Can we call the procedure inside the function?

  Strange question to ask.

  Yes. This is the standard behavior in most (if not all) procedural and object oriented languages.

  A procedure, function or a method is a unit of code.

  You can call one of the other units. Units can call themselves (recursion). Technically, this means simply by pushing the battery current (to save the stack of the current device memory), the call to the new unit and then popping up battery when control is returned to the unity of the appellant.

  There are very few exceptions to this. The only one that comes to mind programming languages I've used through the years, is natural 1 - could not call a new unit of code to replace the existing one in memory. If no call-and-return was possible.

  Exactly what did you ask this question? Some newcomers to confused Oracle SQL and PL/SQL - two different languages aside server. And then also mistaken for PL/SQL client command vocabulary of SQL * more.

  You will need to make sure that understand the basics of programming (applies to most current programming languages) and Oracle concepts.

• Call the procedure to set the context before interactive report refreshes the data

  Hi guys,.

  I have a question mind an interactive report which takes the data in a view.

  The problem is that whenever I take the data from the database I need to define a context (user name and password) before running the query so the view will be taken into account the context and return only the lines that I have access.

  Everything works fine when I'm first loading of the page: I have first to define the context, then load all the data I need on the page, including the IR. But when I try to apply IR filters, or even don't go to the next page no data is returned. I believe this happens because the context is not defined before the execution of the query to load the data and I don't seem to find a way to put it.

  I tried to add a dynamic action on some events on IR (change, clicking, etc.) that executes the procedure to set the context, but without success - even if the event is raised, the report still doesn't return any data.

  Can someone help me with this issue please?

• How to call the procedure Oracle in ODI

  Hello
  
  I use ODI 10 g.
  
  Before you run the interface in a package, I wanted to place my procedure.

  Now, before the execution of my interface, I want to run this procedure in my package. So can some please help me how to call this oracle (creation in target schema) ODI procedure and run it.
  
  Thank you.

  Hi, GRK,.

  You can create an ODI procedure, add one step, choose Oracle as technology and your target schema.
  Then just call it through a pl/sql block:

  BEGIN
   TEST_MY_NEW_PROCE;
  END;
  

  In your package, then drag this ODI procedure.

• Call the procedure this file download, but not from the URL

  Hello
  
  Oracle 11g, Apex 4.1.1.00.23.
  
  I have a procedure that generates a CSV of a query (BLOB). The query uses the apex collections.
  As it seems impossible to use collections of the apex outside Apex, I can't call this procedure from the URL to download the file (the query fails).
  
  How can I call my procedure on click of a button, without reloading the page, and without calling the URL ?
  
  I have some ideas like the creation of a new page, with a conditional header process that calls my procedure to download the file, then call it in a popup, etc... but I need a simple solution...
  
  Thank you.
  
  Yann.
  
  PS: actually, I need the same functionality when you change a process, let us say a process page, in the source attribute, you link < police = "courier" > [Download Source] < / font >, this link simply calls < police = "courier" > javascript:doSubmit('DOWNLOAD') < / font >, but it seems that the page is not reloaded. That's exactly what I need, it does not call for any procedure in the URL, and it does not reload the page.

  Use an application process. These run in the security model for APEX, including the use of the collections.

• Problems trying to call the procedure in a PL/SQL package.

  We use BI Publisher 10.1.3.4.1.
  
  I am trying to call a procedure in a package by using a data model, as I read it is the best way to do it.
  
  Here's the package. Very straightforward, just insertion of a row in a table to try this out. I tested the procedure and that it works correctly.

  CREATE OR REPLACE PACKAGE JM_PKG_OBIEE_ETL_TEST

  Yes you must change the procedure in function first. In addition, even if you do not use parameters here if passing them in you must also declare their in the package specification in the exact order you have set them up in your data source. Change your name to BeforeReportTrigger function (and note the case-sensitive characters). Here is the code that I modified.

• CALL THE PROCEDURE IN THE SQL STATEMENT

  Why we cannot call a procedure inside the SQL statement?

  Hello

  Usually when you select an item should return you data. In the case of a procedure, you cannot return any return value from the procedure directly it has to be done through some settings and to access these settings, you cannot use a simple sql statement. Where as in a function, you must return one of data that can be easily obtained accordingly.

  see you soon

  Hi Amit,

  This is a bug in the wizard of DBAdapter. Try to update BPEL for the latest available patch, and if this does not work here workaround has been tested to work on 10.1.3.1 too!

  1. modify "Main1' to"Main1 (dummy IN VARCHAR2)"in your package.
  2. use the wizard of DBAdapter as ususal to create a partner link that hits this procedure has changed.
  3. change your procedure "Main1" back to the way it was IE without any parameters.
  4. in your BPEL process file, find the file .xsd to Main1 generated by the wizard in step 2. Replace ... inside the for the "InputParameters" element with an emty tag.

  Now, go ahead and invoke this link partner as usual. It would work! ;)

  Kind regards

  ========================================

  Hello

  Welcome to the forum!

  The p_arr argument must be the type defined in the package.
  You cannot substitute your own type, even if the name and the definition are identical.

  Try this:

  create or replace function test_parse_list
  return VARCHAR2
  
  is
     array xyz.ARR_STR;
     ...
  

  where xyz is the name of the package. (I see no parse_list in the Oracle supplied packages 9 manual).
