• How to start the view off of the ref cursor Oracle as input/output param

  Hello world

  We use JDev 11.1.2.3 WL 10.3.6 and Java 7.

  We are at the beginning of our transition from Oracle Forms to ADF.  We have a very large forms that uses many store procedures that have IN/OUT ref Cursor parameters and tables plsql.  I tried to find information on best practices to achieve, but only seemed to find tutorials on SEO of the Oracle ref Cursor return functions.  I hope we don't have to rewrite our code of database to work with ADF.

  This is an example of a proc currently a block on a form based on directly

  The ref cursor parameter is input/output to satisfy the way the form handles this type of paradigm.

  ADF we want I hope to reuse these procs existing (without the need to wrap/overload them) on the basis of the display objects.

  Example:

  / * my record type which houses the information I want to go back * /.

  TYPE rec_hist_vacpac_status IS RECORD)

  rec_order NUMBER (5),

  rec_rownum NUMBER (5),

  return_column SAM_VACPAC.vacpac_status%TYPE,

  rec_login_id SAM_VACPAC.ins_user%TYPE,

  status_date SAM_VACPAC.status_date%TYPE

  );

  / * Sets the ref cursor type * /.

  TYPE lcur_hist_vacpac_status IS REF CURSOR;

  / * This is a procedure that would take some info link go / return

  Return the ref cursor of this information as an in / out * /.

  PROCEDURE prc_myinfo_refcur)

  pnum_identify_seq_id in NUMBERS

  pcur_myinfo IN OUT lcur_hist_vacpac_status);

  Can anyone point me in the right direction on documentation on this?

  Thank you!

  Hi Cemerson:

  See this example:

  1. 1. create a TYPE as an object

  CREATE OR REPLACE

  TYPE GOTYOB_EQUI

  AS AN OBJECT

  (

  CDELEM VARCHAR2 (50).

  TIELEM VARCHAR2 (2)

  );

  1. 2. create a TABLE TYPE AS

  CREATE OR REPLACE

  TYPE GOTYTA_EQUI

  AS THE GOTYOB_EQUI TABLE;

  1. 3 create a function, it returns the TYPE of the TABLE

  FUNCTION fn_equiposarriba)

  pa_cdelem IN VARCHAR2,

  pa_nucomp in NUMBERS

  pa_anperi in NUMBERS

  pa_meperi in NUMBERS

  )

  Gotyta_equi RETURN PIPELINED IS

  If the function returns the ref cursor is the only point of access that you have data then Yes, it probably is. If you have direct access to the underlying database objects and the function does not have something very complicated, then you are probably better off creating your own body of the function returning SQL query data source.

  Everything about the dynamics of ref Cursor now I divided in 2 layers, with a function for generating the dynamic SQL and another for bind parameters open the ref cursor. APEX apps can then reuse the functions of SQL query in function body return SQL query data sources (if you take a bit of care to keep the bind variable names vaguely APEX-point-friendly).

  Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  See this for the technical background on why APEX is not yet support ref Cursor and this for more information of the Oracle team on the possibility of future support. Obviously, he did not he in 4.1. I suspect that data REF CURSOR region sources depended on a minimum requirement of DB of the 11.1.0.6 (where was introduced support for the conversion of the REF CURSOR in the cursors DBMS_SQL). As minimum DB for APEX 5.0 version is 11.1.0.7, it would be a possible feature for 5.0, but it is not classified as one.

• Initialize the Ref Cursor to avoid ORA-01001: Invalid cursor

  Hello
  
  I write a stored procedure that returns a REF CURSOR. However, there are times when the cursor is not open if certain conditions are not met, so I wonder if there is a way to initialize the REF CURSOR so that the appellant does not receive the "ORA-01001: Invalid cursor" error when you try to work with the cursor, if it has not been opened.
  
  Any help is greatly appreciated...

  The most appropriate way would be the caller to handle the situation. The caller must capture the exception of INVALID_CURSOR and do what is necessary.

  Other suggestions like having a separate Pavilion or a model select all will lead the appellant to act to the particular situation, that slider is not being opened. What is the case with the exception of INVALID_CURSOR raised by oracle.

  All the need for the appellant to do is manage the exception of INVALID_CURSOR and you should be good. And also INVALID_CURSOR is not a mistake, it's an exception that has a special meaning for her. In the case you sense it takes the condition when not together to return a cursor.

• help how to extract the ref cursor in the table field

  Hello.
  
  
  I have a query similar to the following:

  select department_id, cursor (select employee_id from employees where department_id = d.department_id)
    from departments d

  Expecting to get several lines, I want this select this option to be in bulk sampled in a table variable nested (of another type of nested table) which is copied to an out parameter in a procedure. I have some doubts:
  1 should. what I create the column in the inner nested table that will keep the result of the ref cursor? Ref cursor colunm? A sort of column Adrien?
  2. If the column in the nested table inside that will keep the result of the ref cursor is another array, how can I write the result of the entire query in a single volume?
  
  (I want to bulk collect everything in a single query, I know how to do with pl/sql do not inflate but using two nested for loops, that's what I try to avoid).
  
  
  Thanks in advance.

  It would be simpler:

  declare
      type dep_emp_list_tbl_type
        is table of sys.OdciVarchar2List;
      v_dep_emp_list_tbl dep_emp_list_tbl_type;

• With regard to the previous discussion on the recent settings of the workspace page

  With regard to the post Re: recent files page , when I went back to answer, there is no way to reply to the post.  After trying the settings using the provided screenshots, page of recent files always came every time.  So the answers you have provided are not correct for my particular case.  Finally, I tried without any control in the preferences and that my custom workspace save as I wanted.  Here is how I had to define it.

  Thank you.

  

  It is doubly strange.  I just check and that the other thread is not locked and can be answered.  Someone else has a problem, you reply to this thread.

  Secondly, I turn off the settings described works for me and Photoshop opens without MRU and start work space.

  You did _uncheck_ these settings?  I like the new workspaces, so mine are checked, but it clearly says _Show_ at the beginning of each line.

  

• With regard to the update of the locations of cards-oracle

  HII everyone,

  In my application, we using mapviewer, which was installed locally on our server, for map rendering and showing the locations of a client like pinball machines.

  Suppose that some places (address, City) is updated map... How mapviewer (which has been installed on our server locally) will update this site all in rendering...

  Thank you

  learner

  It depends on how you got the map features.  Mapfeatures are usually stored in the cache.  If a change in database may not appear in the card immediately.  If, however, given the characteristics of the map as a vectorlayer, then simple vector update updates map.  You should consider two options with regard to the update database process.  You can store the geometry as a function that is updated on the fly as change attributes of database, or you may use a database trigger to update the geometry when the attributes change.  Thus, using a combination of correct space architecture and mapviewer correct functions.

  Hi all

  If I open a cursor once can I collect the elements of a cursor n times as above? I see one of these procedures to print the details, but not both.

  Wonder why that I'm passing same ref cursor to a second procedure.

  It doesn't throw me an error indicating that the elements of the ref cursor is already read.

  Thank you.

  Your condition is not clear. Cursor is a pointer. He points to the result set of your query. At the time wherever you collect once, it advances the pointer to the next line and so on. I wonder if the pointer can return to the previous line once you recovered.

  There are several ways to achieve this. Perhaps the simplest is to simply catch Exception as std::exception const &, or one of its derivatives, then call what(). However, if you want to use the specific exception hierarchy richer consistency, you can get the equivalent of the what() result by calling getDescription()-> getCString(). With regard to the rankings largely what types of exceptions are "fatal", which would be RuntimeException and its derivatives, but the scope which it was caught in general is going to be more telling.

  Clearly the point of my question is being missed.

  Or maybe the question is not been clearly asked. ;)

  I want to set the cursor in the PACKAGE SPECIFICATION, and not in the package body. The issue of the bind variable and the string is neither here nor there because I pass parameters to the cursor.

  What you ask is to use a PL/SQL cursor (defined in the specifications of the package or elsewhere) and that convert a Ref Cursor. N ° cannot be done.
  PL/SQL cursors should be used in the PL/SQL code. REF CURSOR is primary used to pass back a reference to a cursor (and all queries are cursors) to a layer of application outside of PL/SQL for example .net, java, etc.. Once you start using the ref Cursor only really, you have the choice of opening it based on a (dynamic) or a fixed query string as in the examples given. You cannot open a cursor of a PL/SQL cursor definition Ref.

  The difference is that when you do:

    CURSOR cur_mycursor IS
      SELECT ...
  

  you declare a cursor in pl/sql definition, not actually a slider itself. The cursor itself is created when you issue an OPENING or a statement FOR etc. So a Ref Cursor (reference to a slider) cannot refer to the definition of the cursor because it is only a definition, not a cursor (i.e. it has not been sent engine sql and instantiated at that time here). Instead the Ref Cursor must reference a cursor (query), itself, and that may be presented as a string or as the query itself that is issued against the sql engine and then the ref cursor points

  Thus, slider ref and PL/SQL cursors are different concepts, both designed to manage cursors in a slightly different way of programming. You cannot mix them.

• Is it possible to combine dynamic &amp; static queries in the ref cursor?

  Hi all
  
  I was wondering if it is possible to combine dynamic & static queries in the ref-cursor?
  

  CREATE OR REPLACE FUNCTION dynamic_static_kk
     RETURN sys_refcursor
  AS
     o_cursor   sys_refcursor;
  BEGIN
    open 'select 1 fom dual'
         union
         select 2 from dual;
  
     RETURN o_cursor;
  END;

  In the existing code, the two parts of the query are static, but I need to improve & replacement of part would do the trick.
  
  So, I was wondering if it is possible to keep the static part 2. Of course, do both dynamic parts seems the only possible treatment for me.

  So, I was wondering if it is possible to keep the static part 2.
