CLIENT_OLE2.INVOKE_NUM WITH IN OUT PARAMETER

Hi all,
I'm using oracle 10g forms to call out an OCX file. I'm successful in calling the OCX but not in retrieving the output parameters from the ocx function.
Example function inside the ocx file:
function getNextNumber(PNum OUT String , statusString OUT String, statusCode OUT String) return Number
The function returns 0 if the execution is successful. I'm successflul in calling this function and hence getting the value "0" after execution but i'm not able to retrieve the OUTPUT values from the function.
SQL CODE:
DECLARE
IFAOBJ CLIENT_OLE2.OBJ_TYPE;
args CLIENT_OLE2.LIST_TYPE;
StatusVal VARCHAR2(4000) := '0';
PersonNumber VARCHAR2(4000) := '0';
StatusStr VARCHAR2(4000) := '0';
I NUMBER;
BEGIN
IFAOBJ := CLIENT_OLE2.CREATE_OBJ('IFA_API_NG.clsIFA_API_NG');
args := CLIENT_OLE2.CREATE_ARGLIST;
CLIENT_OLE2.ADD_ARG(args, PersonNumber);
CLIENT_OLE2.ADD_ARG(args, StatusStr);
CLIENT_OLE2.ADD_ARG(args, StatusVal);
I := CLIENT_OLE2.INVOKE_NUM(IFAOBJ,'IFA_GetNextPersonNumber',args);
message('I='||I);message('I='||I);
--PersonNumber := CLIENT_OLE2.GET_CHAR_PROPERTY(args,'PERSONNUMBER');

Methods of OLE-objects with IN OUT parameter

How can I invoke a method of an OLE-object with IN OUT parameter?
Trying

Performance issue with using out parameter sys_refcursor

Hello,
I'm using Oracle 10g, with ODP.Net in a C# application.
I'm using about 10 stored procedures, each having one out parameter of sys_refcursor type. when I use one function in C# and call these 10 sp's, it takes about 78ms to excute the function.
Now to improve the performance, I created one SP with 10 output parameters of sys_refcursor type. and i just call this one sp. the time taken has increased , not it takes abt 95ms.
is this the right approach or how can we improve the performance by using sys_refcursor.
please suggest, it is urgent, i'm stuck up with this issue.
thanks
shruti

With 78ms and 95ms are you talking about milliseconds or minutes? If it's milliseconds then what's the problem and does it really matter if there is a difference of 17 milliseconds as that could just be caused by network traffic or something. If you're talking minutes, then we would need more information about what you are attempting to do, what tables and processing is going on, what indexes you have etc.
Query optimisation tips can be found on this thread.. When your query takes too long ....
Without more information we can't really tell what's happening.

Syntax for APEX_PLSQL_JOB.SUBMIT_PROCESS with an OUT parameter

Hi All,
I am using APEX_PLSQL_JOB.SUBMIT_PROCESS and calling a procedure that has both an IN and an OUT parameter.
The IN parameter works fine; I am able to call my procedure from APEX and pass it the :APP_JOB item as the IN parameter. The OUT parameter I can't get working. I can call my procedure from a different block in SqlDeveloper and everything works, so I'm confident that my procedure code is correct. I just can't get the OUT parameter returned via APEX.
This is the plsql code that I'm calling from an APEX dynamic action:
DECLARE
l_sql      VARCHAR2(4000);
l_instance VARCHAR2(30);
   l_job number;
l_rows_processed number;
BEGIN
l_instance := :P9_INSTANCE;
l_sql      := 'BEGIN update_tl_tables_1(:APP_JOB, :F103_ROWS_PROCESSED); END;';
l_job      := APEX_PLSQL_JOB.SUBMIT_PROCESS( p_sql => l_sql, p_status => 'Background process submitted');
l_rows_processed := :F103_ROWS_PROCESSED;
insert into gse_lng_jobs (instance, job_id, rows_processed) values (l_instance, l_job, l_rows_processed);
COMMIT;
END; My procedure is created as:
create or replace
procedure UPDATE_TL_TABLES_1 (l_app_job IN number, l_rows_processed OUT number)
IS......Again, this works fine from SqlDeveloper. Can anyone suggest the proper plsql code? I've tried this using a page item, a system item etc. and no luck. I first tried just passing my procedure a local variable like l_rows_processed, but the procedure wouldn't even run, so I'm assuming the API needs an actual APEX item but I'm out of ideas here.
thanks in advance,
john

That's not going to work because the job hasn't run yet when you perform the insert. So :F103_ROWS_PROCESSED wont contain anything useful.
Why don't you try performing the insert as part of the job, e.g.
l_sql := 'BEGIN update_tl_tables_1(:APP_JOB, :F103_ROWS_PROCESSED); insert into gse_lng_jobs (instance, job_id, rows_processed) values ('''||l_instance||''', '||l_job||', :F103_ROWS_PROCESSED); END;';
...something like that.

How to execute a stored procedure with an out parameter ?

Guys I am struggling with executing a stored procedure from sql plus.I mean my stored procedure has 2 input parameter and 1 out put parameter (status of the execution).
MY_PROCEDURE(p_name in varchar2,p_age in number,p_status out varchar2)
end my_procedure;
When I say
EXECUTE MY_PROCEDURE('manohar','Shetty');
i get insufficient parameters errors.
please help.

EXECUTE isn't a valid PL/SQL construct. It's a SQL*Plus command. You don't want to put any SQL*Plus commands in a PL/SQL block.
You can always execute a stored procedure purely through PL/SQL
begin
my_stored_procedure( x, y, z );
end;SQL*Plus happens to give you the execute command so you can avoid the begin and end statements.

Hi,
Whenever you have an error, post the full eroor message, including the line number.
Indent your code, to show the scope of BEGIN, IF, LOOP, and other statements.
When you post code on this site, type these 6 characters
{code}
(small letters only, inside curly brackets) before and after the actual code, to preserve spacing.
If the procedure is defined as having one argument, an OUT argument, then you must call it with one argument, and it must be a variable (not a literal) of the correct type (NUMBER, in this case).
What is the point of
EXCEPTION
    WHEN OTHERS THEN
        null;
        RAISE;? Why catch the exceptions at all?

How to call a procedure with SYS_REFCURSOR OUT parameter

Hi,
Using Oracle 11g R2.
I'd like to know if it is possible to display the results of a SYS_REFCURSOR in a query. For example, if I had the following stored procedure
create or replace procedure testprocedure (result OUT sys_refcursor)
as
begin
   open result for
      select 1 from dual
      union all
      select 2 from dual;
end;
I'd like to call this procedure similar to the way a query is called and executed. Like this
select * from testprocedure
I've seen plenty of examples on the web which show how it is possible to loop through results of a sys_refcursor inside of an anonymous block and display the results using dbms_output.putline, but this isn't the method I am looking for.

I'd like to know if it is possible to display the results of a SYS_REFCURSOR in a query. For example, if I had the following stored procedure
No - you can only use schema object types (SQL) in SQL queries and only then if you call a function.
The function can return a SQL collection type or it can be a PIPELINED function whose return value is a SQL collection type. Either way your query will use the TABLE function and be of the form:
select * from TABLE(testfunction);
This is sample code for a PIPELINED function based on the SCOTT.EMP table. The function takes a department number parameter and returns the EMP rows for that department:
-- type to match emp record
create or replace type emp_scalar_type as object
(EMPNO NUMBER(4) ,
   ENAME VARCHAR2(10),
   JOB VARCHAR2(9),
   MGR NUMBER(4),
   HIREDATE DATE,
   SAL NUMBER(7, 2),
   COMM NUMBER(7, 2),
   DEPTNO NUMBER(2)
-- table of emp records
create or replace type emp_table_type as table of emp_scalar_type
-- pipelined function
create or replace function get_emp( p_deptno in number )
return emp_table_type
PIPELINED
as
   TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
    emp_cv EmpCurTyp;
    l_rec emp%rowtype;
begin
    open emp_cv for select * from emp where deptno = p_deptno;
    loop
      fetch emp_cv into l_rec;
      exit when (emp_cv%notfound);
      pipe row( emp_scalar_type( l_rec.empno, LOWER(l_rec.ename),
          l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno ) );
    end loop;
    return;
end;
select * from table(get_emp(20))

Error while calling a stored procedure with OUT parameter.

Hi,
I am trying to call a Stored Procedure(SP) with an OUT parameter(Ref Cursor) from a third party tool. It is called using OLE-DB Data provider. In one database the procedure works fine but when I change the database the procedure call is giving following error.
Distribution Object:     COM Error. COM Source: OraOLEDB. COM Error message: IDispatch error #3092. COM Description: ORA-06550: line 1, column 7:
     PLS-00306: wrong number or types of arguments in call to 'TEST1'
     ORA-06550: line 1, column 7:
     PL/SQL: Statement ignored.
I am not able to find as to why is this happening. Please let me know any clues /help to solve this problem.
Thanks in advance.

If you're using Oracle Provider for OLE DB (OraOLEDB) to execute this stored procedure, you need to set PLSQLRSet attribute. This attribute can be set in registry, connection string, or command object. Please refer to User Documentation for more information.

Call stored procedure with OUT parameter

Hello,
I have created a short-lived process. Within this process I am using the "FOUNDATION > JDBC > Call Stored Procedure" operation to call an Oracle procedure. This procedure has 3 parameters, 2 IN and 1 OUT parameter.
The procedure is being executed correctly. Both IN parameters receive the correct values but I am unable to get the OUT parameter's value in my process.
Rewriting the procedure as a function gives me an ORA-01460 since one of the parameters contains XML (>32K) so this is not option...
Has someone been able to call a stored procedure with an OUT parameter?
Regards,
Nico

Scheduled Job Call Package with OUT-Parameter

Hi,

    job_name => 'AUTOIMPORT',
    argument_position => 1,
    argument_value => ''
dbms_scheduler.enable('AUTOIMPORT');
end;After the time specified I query user_scheduler_job_log. The Status column of the table says that the job failed. I think it has to do with the out parameter but I'm not sure.
Can anybody help with this?

With JDBC, calling a stored procedure with ARRAY as out parameter

Hi,
I want to use the data type ARRAY as an out parameter in an Oracle stored procedure. I want to call the stored procedure from
my java program using JDBC.
The problem it's i use a 8.1.7 client to acces with oci to a 7.1.3 Database.
With this configuration I can get back a Cursor but not an Array.
Does it's possible ?
Thanks for your help !
