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

*

Of

TABLE (gopq_eventos.fn_equiposarriba (' F-SCZ-043-103', '))

1,

2013,

)

)

  • 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;
    v_dep_id_tbl sys.OdciNumberList;
begin
    select  department_id, cast(multiset(select employee_id from hr.employees where department_id = d.department_id) as sys.OdciVarchar2List)
      bulk collect into v_dep_id_tbl,v_dep_emp_list_tbl

    Hi DV63,

    Welcome to the Forums EITHER!

    If you downloaded an evaluation version of LabVIEW your 30 day trial must begin immediately after being invited to enter a serial number. You can choose not to enter a serial number and this will begin your trial period. I recommend that you install OR-DAQmx device drivers; It is a software that allows you to communicate with the hardware from National Instruments DAQ. However, this facility will be particularly useful because it allows you to simulate an Instrument with the measurement and Automation Explorer (MAX); This means that you can immediately start the signals in LabVIEW.

    Hi all
    I installed OEM 11.2.1.0. I stopped getting alerts after the 1 server node is restarted. I followed RAC database.

    Please can I know how to start the agent on the nodes and also auto how the boot process of the agent on the server restart

    Thank you.

    I assume that you have installed your agent in the directory

    / u01/app/Oracle/agent11g/bin

    If this is correct then run the following commands

    Export ORACLE_HOME = / u01/app/oracle/agent11g /.
    export LD_LIBRARY_PATH = / u01/app/oracle/agent11g/lib

    PATH = $ORACLE_HOME/bin:. : $PATH; export PATH

    As a matter of fact, you need to set the environment variables separate for the agent to execute commands
    which are related to the agent. These distinct environment must be set correctly to ensure that the
    commands can be found in the appropriate directories...

    Then, run the status command emctl agent...
