Database procedure with IN/OUT parameters

Hi,
I have a procedure with multiple OUT parameters,
but I do not know how to get the values of these out parameters in the calling procedure.
What I mean is I can simply get the value of a function from a calling procedure as:-
declare
val1 number;
begin
val1 := func_get_num;
end;
How can I get the values of OUT parameters of a procedure in a similar way?

like
SQL> var ename_v varchar2(30);
SQL> var empno_v number;
SQL> create or replace procedure get_employee(empno out number, ename out varchar)
2 as
3 begin
4     select empno, ename into empno, ename from emp where rownum <=1;
5 end;
6 /
Procedure created.
Elapsed: 00:00:00.51
SQL> exec get_employee(:empno_v, :ename_v);
PL/SQL procedure successfully completed.
Elapsed: 00:00:00.12
SQL> print empno_v
   EMPNO_V
       666
SQL> print ename_v;
ENAME_V
fdddfdf1
SQL>

Problem with database adapter on plsql procedure with in/out parameters

running BPEL 10.1.3.1 and using the database adapter on a plsql procedure with in/out parameters I get errors
the plsql procedure:
create or replace procedure proc_with_clob_inout_parameter(
p_string in varchar2,
p_clob in out clob)
is
begin
p_clob := p_string;
end proc_with_clob_inout_parameter;
In BPEL I call this procedure. When I only assign a value to the p_string parameters (in a BPEL assign) all is well. When I also assign a value to the p_clob parameter the error occurs:

In BPEL 10.1.2.0 this isn't a problem. I tested it against a 10.2.0.1 and a 10.2.0.2 database and in both situations I get the error with BPEL 10.1.3.1 and no error with BPEL 10.1.2.0
it appears to be a problem in the database adapter...
anyone with the same problems and/or a solution?

Not of any use to you, but we had exactly the same problem on Friday when we applied AS 10.1.2.2 Patchset on top of BPEL 10.1.2.0.2.
The clob in our pl/sql proc wan't declared as in/out but for some reasons JDeveloper had created a clob on the Output Parameter type in the db partner link xsd. I removed this and it worked. This code had been untouched , and working fine, for months.
I'll be raising an SR today.

Reg:execute procedure with in out parameters

hi,
what is the code to execute a procedure with in out parameters.can anyone give me an example
thanks

thanks for the reply.
i am very much new to oracle database.i need this code to put in one of my informatica mapping.
so can you just elaborate what does 'karthick' mean?is it the name of the procedure.No, karthick is the value of the variable that is being passed into the procedure called "P" in karthicks example, then if that procedure changes the value inside, the variable will have that new value passed back out of the procedure to it.
PROCEDURE prc_mv (name VARCHAR2)

dbms_mview.refresh('mv2','C');
response := 1;
EXCEPTION
WHEN OTHERS
THEN
response := 0;
END refresh;
can you give the code for this procedure.Yes.
DECLARE
v_response NUMBER;
BEGIN
refresh(v_response);
END;Though your code is awful. There's no point in having the response parameter as an IN OUT if you're not going to pass IN a value and use that in the code anywhere. In your case it only needs to be an OUT parameter because you're just passing back OUT a value. You are also masking any exceptions that happen by using a WHEN OTHERS clause.
Better code would be something like...
FUNCTION refresh (mv_name) RETURN NUMBER IS
v_response NUMBER := 0; -- default response value
e_mv_not_exist EXCEPTION; -- exception variable
PRAGMA EXCEPTION_INIT(e_mv_not_exist, -23401); -- connect exception name to internal oracle error number
BEGIN
dbms_mview.refresh(mv_name,'C');
v_response := 1;
EXCEPTION
WHEN e_mv_not_exist THEN -- handle specific expected exception
    -- if the materialized view does not exist, handle it gracefully as we don't want to stop
    response := 0;
END refresh;
declare
v_response NUMBER;
begin
v_response := refresh('mv1');
if v_response = 0 then
    -- the materialized view did not exist
else
    -- the materialized view refreshed ok
end if;
end;where your exception handler explicity checks for expected exceptions such as :
ORA-23401: materialized view "SCOTT"."FRED" does not exist... and any other exceptions that you're not expecting will be raised for you to see.
It's also better as a function because you don't need to pass in a response value, you just want to get a response value back.
There's rarely a good need to use OUT or IN OUT parameters. (there's some cases, but it's not something to consider doing as part of your regular design)

I need an example of oci V7.3 to call stored procedure with IN/OUT parameters.

Hi,
I'm developing an application to access data from Oracle V7.3 using OCI. Is there a way to get the IN, OUT and IN/OUT parameters of a stored procedure from the database ? How can I execute the stored procedures dynamically, through OCI and get the data back ? Is there any sample programs ?
Any help is appreciated.
Thanks
David Lin

Since ODP.NET does not support Oracle Object type, you can not call this stored procedure directly.
You can write a wrapper procedure over the existing procedure accepting basic types, e.g. Varchar, Number, etc. and call your stored procedure after creating a object from the basic types.

Calling Oracle procedure with two OUT parameters

Hi I am having an Oracle procedure which return ref cursor. I also want to result one more out parameter result. How Can I call the procedure in SQL. Below is the way I am calling my stored procedure with one parameter.
proc_Test (p_resultset=> My_cursor)
How can I call the procedure when I have one more OUT parameter. Second parameter returns 0 or 1.
Thanks in adv

Yes its possible to use multiple parameter as OUT type in procedure.

Calling a Procedure with IN & OUT Parameters

Hello,
I usually call my procedures using the following way
declare variable error_msg varchar2(50)
exec simple_msg('ABC,'ABC','ABC',:error_msg);
CREATE OR REPLACE PROCEDURE SIMPLE_MSG (
ID IN VARCHAR2,
URL IN VARCHAR2,
LIST IN VARCHAR2,
ERROR_MSG OUT VARCHAR2
Now my question is i am trying to call a proc which has IN OUT parameters. Can somebody guide me on how to call the proc. Thanks
CREATE OR REPLACE PROCEDURE SIMPLE_MSG (
ID IN VARCHAR2,
URL IN VARCHAR2,
LIST IN VARCHAR2,
NAME IN OUT VARCHAR,
ERROR_MSG OUT VARCHAR2

Hi,
IN OUT parameters are passed just like OUT paramenters: you must pass a variable.
If you need to set the IN OUT parameter before calling the procedure, then either
(a) use a separate EXEC command:
EXEC :name := 'Original name';
EXEC simple_msg ('ABC', 'ABC', 'ABC', :name, :error_msg);or
(b) use an anonymous PL/SQL block, like this:
BEGIN
:name := 'Original name';
simple_msg ('ABC', 'ABC', 'ABC', :name, :error_msg);
END;
/The parameter can be either a bind variable (as shown above), or a local variable (that can be used only in the block).

SQLException Calling Stored Procedure with Date OUT Parameters

oracleCallableStatement.registerIndexTableOutParameter(6, 100, OracleTypes.DATE, 0);
oracleCallableStatement.registerIndexTableOutParameter(7, 100, OracleTypes.DATE, 0);
resultSet = oracleCallableStatement.executeQuery();
When I run the code, I get a "java.sql.SQLException: Invalid PL/SQL Index Table" exception on oracleCallableStatement.executeQuery(). I tried many other variations and searched on forums but nothing worked for me. Does anyone have any idea? I'm really desparate. i use JDK 1.4.2_12 and WebLogic 8.1 SP6.

Hi Avi,
I think you are right and I was using the wrong method. With some help from our DBA the problem was resolved Here is the correct code:
connection = this.datasource.getConnection();
oracleCallableStatement = (OracleCallableStatement) connection.prepareCall("begin " + STORED_PROCEDURE_NAME

oracleCallableStatement.registerOutParameter(4, OracleTypes.ARRAY, "COLL_SEGINFO_SEGMENT_NAMES");
oracleCallableStatement.registerOutParameter(5, OracleTypes.ARRAY, "COLL_SEGINFO_STATUSS");
oracleCallableStatement.registerOutParameter(6, OracleTypes.ARRAY, "COLL_SEGINFO_START_DATES");
oracleCallableStatement.registerOutParameter(7, OracleTypes.ARRAY, "COLL_SEGINFO_END_DATES");
oracleCallableStatement.execute();
String[] segmentCodes = (String[]) oracleCallableStatement.getARRAY(3).getArray();
String[] segmentNumbers = (String[]) oracleCallableStatement.getARRAY(4).getArray();
String[] segmentStatuses = (String[]) oracleCallableStatement.getARRAY(5).getArray();
Timestamp[] startDates = (Timestamp[]) oracleCallableStatement.getARRAY(6).getArray();

for (int i = 0; i < segmentCodes.length; i++) {
System.out.println(segmentCodes[i] + ' ' + segmentNumbers[i] + ' ' + segmentStatuses[i] + ' ' + startDates[i] + ' '

Executing procedure with IN OUT parameters using SQL developer

Hi, I'm trying to exceute the below procedure in SQL developer. Here the IN OUT cursor 'journal_cursor' is already defined.
PROCEDURE LIST_FORPROJECT (
          p_project_sid IN NUMBER,
          p_journal_cursor IN OUT journal_cursor,
     AS
     BEGIN
          OPEN p_journal_cursor FOR
          -- get the journal
               SELECT j.JOURNAL_KEY AS "Journal_SID",
                         j.JOURNALTEXT AS "Entry",
                         j.CREATEDATE AS "CreateDate",
                         --j.COMMENT_ AS "Comment",
                         j.PROJECTPHASETASK_KEY AS "ProjectPhaseTaskSet_SID",
                         j.person_key AS "Person_SID"
FROM vdl_JOURNAL j
               INNER JOIN vdl_PROJECTJOURNAL pj ON pj.JOURNAL_KEY = j.JOURNAL_KEY
               WHERE pj.PROJECT_KEY = p_project_sid
               ORDER BY j.CREATEDATE ASC, j.JOURNAL_KEY ASC;
END LIST_FORPROJECT;
When trying to run the above procedure through SQL developer, I get the below code generated.
DECLARE
P_PROJECT_SID NUMBER;
P_JOURNAL_CURSOR journal_cursor;
BEGIN
P_PROJECT_SID := 5974;
-- Modify the code to initialize the variable
-- P_JOURNAL_CURSOR := NULL;
-- Modify the code to initialize the variable
LIST_FORPROJECT(
P_PROJECT_SID => P_PROJECT_SID,
P_JOURNAL_CURSOR => P_JOURNAL_CURSOR,
-- Modify the code to output the variable
DBMS_OUTPUT.PUT_LINE('P_JOURNAL_CURSOR' || P_JOURNAL_CURSOR);
END;
But executing the above sql doesn't print the cursor as output but errors out saying 'wrong number or type or arguments in call to ||'. Can somebody please help me in finding a way test and view the results of such a procedure through SQL developer?
Any help is highly appreciated.

Hi,
I was able to solve the problem.. My cursor was declared like this.
TYPE journal_def IS RECORD
          journal_sid                    NUMBER(10),
          journaltext                    CLOB,
          createdate                    DATE,
          projectphasetaskset_sid     NUMBER(10),
          person_sid                    NUMBER(10)
TYPE journal_cursor                    IS REF CURSOR RETURN journal_def;
I used the journal_def type to fetch the records.
Here is how my final sql looked like.
DECLARE
P_PROJECT_SID NUMBER;
P_JOURNAL_CURSOR journal_cursor;
P_J_CURSOR journal_def;
BEGIN
P_PROJECT_SID := 11171;
-- Modify the code to initialize the variable
-- P_JOURNAL_CURSOR := NULL;
LIST_FORPROJECT(
P_PROJECT_SID => P_PROJECT_SID,
P_JOURNAL_CURSOR => P_JOURNAL_CURSOR,
-- Modify the code to output the variable
BEGIN
--open P_JOURNAL_CURSOR;
loop
fetch P_JOURNAL_CURSOR into P_J_CURSOR;
exit when P_JOURNAL_CURSOR%NOTFOUND;
DBMS_OUTPUT.put_line(P_J_CURSOR.journal_sid);
end loop;
--close P_JOURNAL_CURSOR;
END;
END;
This gave me results. Thanks a ton ALL for your help..... :)..

Procedures with sys_refcursor out parameters as apex report source

I would like to be able to just call packaged stored procedures that return ref cursors as Apex report region sources. Can anyone explain to me why Apex is not able to do this?
Cheers
The FunkyMonkey

I now have a apex report based on a pipelined table function which uses a collection based on the original select query. So the Apex report source is now a one liner with the now reusable code squirrelled away in a package...Happiness, it works a treat. :-)

Toplink support for stored procedure with 2 OUT REF CURSOR ?

Can Toplink StoredProcedureCall be used with Oracle PLSql procedure with 2 OUT parameters. Parameter type is Ref Cursor (Oracle PLSQL resulset)
Regards

In a TopLink StoredProcedureCall using an OUT CURSOR the cursor is assumed to map to the result set for the TopLink query.
For example if you had a stored procedure READ_ALL_EMP that returned a out cursor of EMP rows, you could use that procedure in a TopLink mapped Employee class mapped to the EMP table and use the stored procedure in a ReadAllQuery for the Employee class.
If the procedure does not return data that maps to objects, you can use a DataReadQuery to access the data. The out cursor would be returned as a Vector of DatabaseRows that contain the data from the cursor rows.
If the procedures data is complex and does not map to objects, it may be better to access the procedure directly through JDBC.

Problem with IN OUT parameters whiloe calling procedure from Form 6i

Hi
Could some help please? I have the following scenario.
I am calling a stored procedure from form 6i by pressing a button on the form. Procedure has two IN OUT parameters, and I am passing these two IN OUT parameters and have declared them the way they are declared passed to the procedure. But I get an error when calling that procedure with these IN OUT parameters. the procedure works fine if parameters are IN only. The error says:
PLS:00363: Expression '1' cannot be used as an assigment target.
NO matter I pass some value or leave it blank, I get the same error message persistenetly.
Please help.
Thanks

make sure you are calling your procedure with variables as parameters,
i.e.
      l_v1 := 1 ;
      l_v2 := 'hello world' ;
      your_proc(l_v1, l_v2)
not
      your_proc(1,'hello world')

Web service with multiple out parameters

Hi Developers,
I have been playing around with som web services in the developer studio.
I can create a webservice from a normal ejb.
But i can only get one out parameter, which is the return parameter of the ejb.
I tried to make an object to use as return parameter, but then i couldn't use the method for the web service.
Can anyone tell me how to make a web service with multiple out parameters?
Br Rasmus

Hi Developers,
I have the same question, is it possible to have multiple outgoing parameters?
When not, does SAP Netweaver knows a IN-OUT parameter? Because I found on the internet that it is possible to have a IN-OUT parameter. But that was with the BEA Weblogic 8.x.
When not, is then the only solution to return a object? With in this object all the parameters you want.
Or otherwise is there a other workaround?
Thanks in advance,

StoredProcedureCall with IN OUT Parameters order in Stored Procedure

Refer to the Toplink documentID:Note 224269.1 - Using IN, OUT and INOUT parameters with StoreProcedureCall. This document can be download from OracleMetaLink:
http://www.oracle.com/support/metalink/index.html
I followed the sample code in this document to write a test case for one of complicated PL/SQL codes. The test case showed wrong results for IN/OUT and OUT parameters.
At the end of the document above, I found this paragraph
" Check the ordering of the arguments to make sure that they are in the following sequence:
All 'IN' parameters, All 'OUT' parameters and then all 'INOUT' parameters.
Your stored procedure must be set up the same way, since this is how values will be passed to it. This is the way in which TopLink stored procedure calls have been designed and implemented. "
The order of our PL/SQL codes is IN, IN/OUT and OUT. We are not allowed to change our PL/SQL codes because they are currently used in production environment. We do not want to create another versions of PL/SQL codes to comply with IN, OUT, IN/OUT parameter order mentioned above.
Do you have any work around solution?

Using procedure with multiple out variables in a query

Hi,
We have a procedure that is time-consuming, which returns 4 variables as out parameters:
procedure calc_values(id in number, val1 out number, val2 out number, val3 out number, val4 out number) isThe id uniquely identifies an product in our database.
I would like to use this in a query (or view), in the form
select s.id, val1, val2, val3, val4 from something s, product_table p
where s.id = p.idI have tried the following approach, but I am kinda stuck
* define a type
* define a table of this type
* write a wrapper function that calls this procedure and returns the results as a table
* pivot the table into columns
* join this with the product table
It feels like I am on the wrong track, i am having trouble to get the id from the product table back into the wrapper function.
Is there a better approach to this? I am on oracle 10g
Thanks!

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.

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))
