Invoking Oracle stored procedures from within a JDBC channel for PI 7.1

Hi ,
Can anybody tell me that is it possible to invoke Oracle stored Procedure from within a JDBC sender channel for PI 7.1.
Its working in XI3.0 and XI 7.0 for Oracle DBMS versions >= 10.2.x. But I am not sure,whether it will work for PI 7.1 also.
Thanks & Regards,
Saru

HI,
refer below link,there is no much difference in PI7.1 ,executing stored procedure is same .

Error Calling Oracle Stored Procedure From Within Report

Hi,
I have a report that calls an oracle stored procedure which returns a ref cursor. The report is working ok in our development environment when called from our development website through .NET.
When the report is moved and accessed from our UAT website we get the following error :-
Failed to open a rowset. Details: ADO Error Code: 0x Source: Microsoft OLE DB Provider for Oracle Description: One or more errors occurred during processing of command. Failed to open a rowset. Details: ADO Error Code: 0x Source: Microsoft OLE DB Provider for Oracle Description: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'RHS_GET_CAND_SECTION_REFS' ORA-06550: line 1, column 7: PL/SQL: Statement ignored Native Error: Failed to open a rowset. Error in File C:\WINDOWS\TEMP\temp_d663a952-bef6-4bf7-bf1a-5e288afdb612 {9B6DFB38-A436-4940-9D80-B4C23DFFFF19}.rpt: Failed to open a rowset.
If we open the report manually we are prompted to enter database connection info. If we enter the UAT connection details the report runs ok. If we save the report and try to open it from UAT website through .NET it now opens ok.
If we then move that same report back to the development environment and open from our development website it fails with the same error above.
Both connections are using Microsoft OLE DB drivers and the Oracle databases are the same version (10.2.0.1.0).
Is the connection information being stored in actual report and somehow being used when the report is opened through .NET?
Any help appreciated

Problem in calling Oracle stored procedure from Java.

I am trying to invoke the Oracle stored procedure from Java. The procedure does not take any parameters and does not return anything. If I call it from SQL prompt it is working perfectly. I am calling it in my program as follows.
callable_stmt=con.prepareCall("{call pkg_name.proc_name()}");
callable_stmt.execute();
The problem is the control-of-flow is getting strucked in the second line I wrote. It is not giving any error also.
Please clarify me what's wrong with my code?
Seenu.

And how long does the stored procedure take to run from your client machine when running it via sqlplus?

How to limit the response rows while invoking a stored procedure from OSB 10gR3

Dear Experts,
I am trying to limit the response while invoking a stored procedure from OSB via DB adapter.
Here the stored procedure returns cursors as response. I tried using the MaxTransactionSize propertiy (which is used for polling the database option in DB adapter).
We are investigating the ways to protect the application from response containing huge number of rows.
Is there any way to restrict the number of rows returned in each and every cursor while invoking the stored procedure via DB adapter?
Thanks
Ram

Hi James ,
I want to know how to run stored procedure using jca adapter in OSB11g.
I am new to stored prcoedure,will be great if you could share some example on it as above.
Req: Single input xml will be posted on queue ,need to perform 3 DB operation (with same input):
1.Insert operation to insert master table contents.
2.select the primary key column value from master table for the last inserted record.
3.Need to insert primary key column value + other fields frm same xml file to child table.
Pls assist me on how to create a simple stored procedure and to run the same with OSB 11g.I am familiar with creation of DB adapter using Jdeveloper,we have option to perform insert and to call stored procedure here,will it be useful for this scenario?

Calling Oracle stored procedure from xMII Query Templates.

Hi All,
We have a requirement to call a Oracle stored procedure from xMII, the SP expects some inputs and then it returns multiple rows.
I tried different approches with no results, I remember some posts on the same topic but I could not get in search results.
Looking for some help in this regards
Rupesh.

Hi Rupesh Bajaj,
In oracle stored procedure we have to use Packages..if you used packages the u have to assign to some variable.
To calling Stored procedure in Query Template is CALL Testing('[Param.1]','[Param.2]',,:X)
In above line Testing is Stored procedure name and Param.1 is parameters and X is Package.
Thanks

Execute Oracle Stored Procedure from Excel

Is it possible to execute an Oracle Stored Procedure from Microsoft Excel and return the result of the Oracle Store Procedure into the excel spreadsheet.

Yes. You can use Oracle Objects for OLE to accomplish this. It comes with Excel examples and an online help file with many more examples.

Executing an Oracle Stored Procedure from Sender JDBC adapter

I could really use some help from someone who had done this before.
I've read the help about using the JDBC sender adapter, but it's not helping enough.
I found this line: "Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
The expression must correspond to the SQL variant supported by the relevant JDBC driver. It can also contain table JOINs."
That's definately what we want to do, but we can't figure out the syntax.
The procedure in oracle looks like this:
CREATE OR REPLACE PROCEDURE test_ref_cursor
( cur_generic IN OUT result_sets.cur_generic)
as
BEGIN
Open cur_generic for
select
   proposal_number,
   to_char(sequence_number),
   column_name,
   column_value,
   update_timestamp,
   update_user
   from
   coeus.sap_test;
END test_ref_cursor;
And we have tried every kind of statement we can think of, but the file adapter always gives us an "invalid sql statement" error.
Does anyone know what syntax we need to put in the "Query SQL Statement" in the JDBC sender adapter in order to call this procedure? Or is there something wrong with the procedure that is causing the error?
<i>I will absolutely return and give points, but PLEASE read my whole post before answering and do not just link me to or quote the help for configuring a sender JDBC adapter or blogs that are about the JDBC adapter in general but do not deal with the issues I am having. Thank you.</i>

Hi Vanda,
Unfortunately, the sender JDBC adapter does not support Oracle's store procedure/function. Unlike stored procedures from other database vendors, Oracle returns a cursor, not a resultset. The sender JDBC adapter must send a resultset to XI.
There are 2 possible ways you can accomplish this:
1. Use BPM and call the Oracle stored procedure using a receiver adapter via a asynch-synch bridge.
2. Develop a user-module for the adapter, which can be used with a sender adapter.
Thanks

Calling a stored procedure from within a ViewObject

Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
If not, is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.

Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
Yes. Using our expert-mode query feature this is possible.
is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
Yes. See this article about basing a view object on a REF CURSOR:
http://radio.weblogs.com/0118231/2003/03/03.html
In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
No. Not directly. What's the business requirement here so I can understand better?
We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.
REF CURSOR would work fine, or if it's just the statement that needs to be generated dynamically, you could fetch the text of the SQL statement from the stored procedure, then use createViewObjectFromQueryStmt(). Although this has runtime overhead involved with describing the query.
The REF CURSOR based approach is probably best for this.

How to invoke Oracle stored procedures in Web Intelligence Custom SQL ?

Hi,
Referring to some older posts, I see that there is a work around to invoke a stored procedure to return results for a Web Intelligence report. Its been posted for calling a MS SQL stored proc, whereas the mentioned method does not seem to work for an Oracle Stored Procedure.
Steps I followed:
a) This is the parameter I have added in the oracle.sbo file => <Parameter Name="Force SQLExecute">Procedures</Parameter>
b) My stored procedure code is as follows:
CREATE OR REPLACE PROCEDURE get_emp_details(var_first_name OUT VARCHAR) AS
BEGIN
SELECT first_name INTO var_first_name
FROM EMP_DETAILS_VIEW
WHERE EMPLOYEE_ID = 100;
END;
c) Custom SQL code I added in my Webi report:
set nocount on;
/* SELECT
EMP_DETAILS_VIEW.FIRST_NAME
FROM
EMP_DETAILS_VIEW
exec get_emp_details;
On trying to validate the SQL it gives me the following error message: "The SQL query has 0 instead of 1 columns.(WIS 10810)"
Has anyone been able to successfully call an Oracle Stored procedure using the above method ?
Version of BO: XI R3 SP2
Oracle version: 11gR2
PS: I am aware that web intelligence since XI R3.1 does allow use of a dedicated Stored Procedure Universe. I would want to know if it could
be made to run in a normal Universe(not a stored procedure Universe)
Thanks for your time and inputs.
Regards,
Jez

EXECUTE is a SQL Plus command. You can directly call SP in PL/SQL
DECLARE
    modif number;
BEGIN
select data_length into modif from user_tab_columns where table_name='CONTROL' and column_name='POSITION';
IF modif < 10 THEN
    droptable('CONTROL');
    execute immediate('CRETAE TABLE CONTROL ....';

How to invoke a stored procedure from SubmitEditForm.jsp

Instead of directly inserting or updating
the data I would like to invoked
the stored procedure.
Has anybody done this?

          Sam,
          BEA provides examples that are shipped with the product under
          <beahome>\weblogic700\samples\server\src\examples\
          Look at the jsp directory for JSP examples that access a database and look at
          say the jdbc\oracle\storedprocs.java for an example of java code calling out to
          a stored procedure - - by combining one of the jsp database examples with this
          stored procedure example you should be 'good to go'

Physical service to invoke Oracle stored procedure taking an object type

Hello,
I have some stored procedures in Oracle that take a complex object type as parameters. Can I invoke these directly from ODSI? If so, how do I create the physical service for this?
Example:
CREATE OR REPLACE TYPE "CCSUSERDV"."TEST_TYPE" as object (
name varchar2(80),
text varchar2(1000),
some_other number
CREATE OR REPLACE PACKAGE CCSUSERDV.TEST
as
function joinText(inVal in TEST_TYPE) return varchar2;
end;
CREATE OR REPLACE PACKAGE BODY CCSUSERDV.TEST
AS
FUNCTION joinText(inVal in TEST_TYPE) return varchar2 AS
BEGIN
if (inVal.text is not null) then
return inVal.name || '-' || inVal.text;
else
return inVal.name || ':' || inVal.some_other;
end if;
END;
END;
I Want to be able to call TEST.joinText from OSDI. I know I could create a separate function that takes all the attributes of my object, but it would be considerably more convenient to implement in terms of the object instead, because there are several functions that take the same set of about 20 fields as a request.
Thank you!!
Jeff

(1) Your best bet is to create a wrapper stored procedure that takes simple arguments and constructs the object, then calls your stored procedure with the object. You call the wrapper stored procedure from ODSI. JPublisher can create wrapper stored procedures for you.
(2) If it is impossible for you to create a wrapper stored procedure in the database, you can create a physical data service from the existing stored procedure. You will notice that the function in the physical data service will have simple arguments (not the object), and if you try to execute it, it will fail. It's up to you to write an anonymous pl/sql block that wraps the existing stored procedure (basically what you would have had to write for (1)), and edit the metadata in the physical ds - where it has the name of the stored procedure, replace the name with your anonymous PL/SQL block.
Below is what the CREATE_BATCH stored procedure from Oracle Process Manufacturing would look like. (it also has CURSOR args - so it is uglier than just Objects). It also demonstrates that you need to do a conversion of boolean args.

Invoking ORACLE Stored Procedure

Hello guys,
I have an ORACLE stored procedure which I need to invoke. I'm currently unable to invoke the stored procedure since I'm always getting the same error:
com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'test.set_pickup' (structure 'STATEMENTNAME'): java.sql.SQLException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'SET_PICKUP' ORA-06550: line 1, column 7: PL/SQL: Statement
I've faced several projects where we needed to invoke stored procedures but these were located in a DB2 or Microsoft SQL Server, and these problems never occured.
The procedure is set to the minimum, and is now only with one input parameter. I had an input and output parameter but for narrowing the problem I've removed the output.
The structure for the stored procedure is the one that is referred by SAP or mentioned thousand of times in this forum:
Statement_name
StoredProcedureName (attribute ACTION)
TABLE
P_TRANSACTION_ID (Attributes isInput, isOutput, type)
For the basics I'm only filling with one statement.
I've read some threads with a similar problem but with no response, or solved but with no suggestion on how they solved it.
Could you please help out?
Kind regards,
Gonçalo Mouro Vaz

Hi,
Is the structure in Oracle side is of the following format?
<StatementName>
<storedProcedureName action=u201D EXECUTEu201D>
<table>realStoredProcedureeName</table>
<param1 [isInput=u201Dtrueu201D] [isOutput=true] type=SQLDatatype>val1</param1>
</storedProcedureName >
</StatementName>
Can you paste the structure here?

Calling Oracle Stored Procedure from BC4J JSP App

I am on an extremely tight deadline and am trying to get my JSP application to use an Oracle Stored Procedure. I need to take some input from the user and send these values as parameters. Has anyone worked with Stored Procedures in JDev3.1? Please reply with some sample code if possible.
Thanks.

Hi,
Someone posted a similar request the other day. Here is my response to them:
Basically, you need to create a custom method from your JSP's ViewObject, which calls the stored procedure. You can then call the ViewObject's custom method from the JSP client.
Here is how I have done it:
1. Choose the ViewObject that your JSP is based on and choose 'Edit' from the context menu.
2. On the Java tab of the ViewObject wizard, choose Generate Java File checkbox for the View Object Class and click the Finish button. A file is created under the ViewObject node in the Navigator named 'viewobjectImpl.java'.
3. Open the viewobjectImpl.java file in the code editor and create a method to call your stored procedure (see sample code below).
4. Compile the VOImpl.java file.
5. Choose the view object again, and choose Edit again from the context menu.
6. On the Client Methods tab, you should now see your method appear in the Available field. Select it and shuttle it to the Selected field.
7. Click Finish to leave the VO wizard, and rebuild your Business Components project.
8. In your JSP, call the custom method (see sample code below).
sample code for custom method calling a stored procedure from VOImpl.java file:
public int getTotalHits(String mon, String year) {
CallableStatement stmt = null;
int total;
// the call to the PL/SQL stored proc
String totalhits = "{? = call walkthru.total_hits(?,?)}";
// use the AM conxn 2 call storedproc
stmt = getDBTransaction().createCallableStatement(totalhits, 1);
try
// Bind the Statement Parameters and //Execute this Statement
stmt.registerOutParameter(1,Types.INTEGER);
stmt.setString(2,mon); stmt.setString(3,year);
stmt.execute();
total = stmt.getInt(1);
catch (Exception ex)
throw new oracle.jbo.JboException(ex);
finally
try
stmt.close();
catch (Exception nex)
return total;
sample render code for calling custom method from JSP custom bean:
public void render() {
int totalhits;
try
Row[] rows;
// Retrieve all records by default, the qView variable is defined in the base class
qView.setRangeSize(-1);
qView.first();
rows = qView.getAllRowsInRange();
// instantiate a view object for our exported method
// and call the stored procedure to get the total
ViewObject vo = qView.getViewObject();
wtQueryView theView = (wtQueryView) vo;
totalhits = theView.getTotalHits(session.getValue("m").toString(),session.getValue("y").toString());
out.println(totalhits);
} catch(Exception ex)
throw new RuntimeException(ex.getMessage());
}

Execute oracle stored procedure from C# always returns null

Hi,
I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
Below are the SP, and the code used from .Net to call it, if that can help.
Oracle SP:
CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
v_status VARCHAR2(5) := NULL;
BEGIN
BEGIN
SELECT CHECK_NO_EXISTENCE(to_char(l_number))
INTO v_status
FROM DUAL;
EXCEPTION WHEN OTHERS THEN
v_status := NULL;
END;
DBMS_OUTPUT.PUT_LINE(v_status);
END CHECK_CONTRNO_EXISTENCE;
C# Code:
string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
OracleConnection conn = new OracleConnection(connStr);
OracleParameter param1 = new OracleParameter();
param1.ParameterName = "v_status";
param1.OracleType = OracleType.VarChar;
param1.Size = 5;
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter();
param2.ParameterName = "l_number";
param2.OracleType = OracleType.Number;
param2.Direction = ParameterDirection.Input;
param2.Value = 006550249;
OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(oraParams);
conn.Open();
object result = cmd.ExecuteScalar();
conn.Close();

Hi,
Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
See if this helps.
Cheers,
Greg

Calling Oracle Stored Procedure from Weblogic.

Hi All,
I am using Oracle 11g R2 and weblogic 10.3.5.0
Do you know if it is possible to call a stored procedure from Weblogic.
Basically, what I would like to do is to call the following procedure : EXEC DBMS_SESSION.SET_IDENTIFIER('provider_a') when my application connects to my database, "provider_a" being the user used to connect to the oracle schema.
Thanks.

Up !
Thanks.
