View BC item from the ref cursor oracle

Is there an easy way to jdev 11.1.1.4 to create a view based on a ref cursor oracle object?

It's in the docs http://docs.oracle.com/cd/E21043_01/web.1111/b31974/bcadvvo.htm#sm0341 search for 'How to create a display on a REF CURSOR object'
An example can be found here http://adfpractice-fedor.blogspot.de/2011/01/adf-bc-programmatically-populated-vo.html

  • 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

    CURSOR trae_equimani (va_cdelem VARCHAR2) IS

    SELECT cdelem, tielem, cdelempadr,

    (SELECT cdequi

    Of evm_alim

    WHERE anperi = eq.anperi

    AND meperi = eq.meperi

    AND nucomp = eq.nucomp

    AND cdalim = eq.cdalim) cdalim

    Of evm_equimani eq

    WHERE anperi = pa_anperi

    AND meperi = pa_meperi

    AND nucomp = pa_nucomp

    AND cdelem = va_cdelem

    AND cdelempadr <> cdelem

    AND tielem <> 'A ';

    equimani trae_equimani % ROWTYPE;

    va_cdalim VARCHAR2 (100);

    BEGIN

    -Loading los equipos aguas arriba

    WHILE equimani.cdelempadr IS NOT NULL LOOP

    OPEN trae_equimani (equimani.cdelempadr);

    equimani: = NULL;

    SEEK trae_equimani INTO equimani;

    CLOSE Trae_equimani;

    IF equimani.cdelem IS NOT NULL THEN

    PIPE ROW (gotyob_equi (equimani.cdelem, equimani.tielem));

    END IF;

    END LOOP;

    RETURN;

    END;

    1. 4 SQL Query with the help of the function... you can use this SQL in a display object

    SELECT

    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.

    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.

  • 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...

    Thank you

    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;

begin

      bulk collect into v_dep_id_tbl,v_dep_emp_list_tbl
      from hr.departments d;
end;

  • 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?

   o_cursor   sys_refcursor;
BEGIN

   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.

  • Automator: using a text file to set several items from the finder?

    Hello

    what I would do:

    I have a text file that contains multiple entries for files and folders, each on a separate line. I want to dragndrop this file on an automator action, he should ask me a destination folder and then copy all the files and folders in this folder.

    I have my action, automator, set up like this:

    Elements of the open Finder

    Get the content of the TextEdit Document

    Copy to the Clipboard (I have not found another way to keep my text sort file values and let it not be crushed by the following, but it works)

    Quit the Application (TextEdit)

    Ask the Finder items (this requires a destination folder)

    Set the value of the Variable (Destination)

    Get the contents of the Clipboard

    Copies the items from the Finder (at Destination)

    It all works, but only when there is 1 entry in my text file. As soon as I have 2 lines of text, I get the following error message:

    The action "copy Finder items" has not provided with the required data.

    How can I make this work with multiple entries?

    The problem is that you only pass the only element to the copy action (you have copied text), instead of an element for each line (paragraph) in the text.  The solution is to use the action filter paragraphs to break up along the borders of paragraph text, which will give you a list of items.  In addition, you do not necessarily have to use TextEdit or the Clipboard - If you already have a file somewhere, you can simply use the action to combine text files to read the text.

    With the above modifications, your workflow should look like:

    Ask the Finder items  (ask for a destination folder)

    Set the value of the Variable  (Destination)

    Ask the Finder items  (Download text files) - set the action to ignore the entry

    Combine text files  (read the text files)

    Filter paragraphs  (paragraphs which are not empty return)

    Copy the items to the Finder  (at Destination)
