Pass xmltype to oracle stored procedure

I need to pass an xmltype from java to an oracle stored procedure. Does anybody have any sample code to do this? I am using jdeveloper 10.1.2
Thanks

Oracle provides several ways of passing objects to and from java to Oracle Stored Procedure.
One way is to directly create oracle.sql.STRUCT object and pass array of values to this object. Another way is to implement java.sql.SQLData or oracle.sql.ORAData interfaces in your class and pass this class to setObject function.
It is all well described in manual in chapter "Working with Oracle Object Types", there is also a lot of examples in this chapter and on the web.

Passing data from Oracle stored procedures to Java

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.

I'd appreciate any hints.If logic is already written in DB, and the only concern is of passing the result to java service side, and also from point of maintenance problem and flexibility i would suggest to use the sys_refcursor.
The reason if Down the line any thing changes then you only need to change the arguments of sys_refcursor in DB and as well as java side, and it is much easier and less efforts compare to using and changes required for Types and Objects on DB and java side.
The design and best practise keeps changing based on our requirement and exisiting design. But by looking at your current senario and design, i personally suggest to go with sys_refcursor.

Passing arrays to Oracle Stored procedure.

Have any body passed arrays to Oracle stored procedures while the app is running in Weblogic app server. I am able to pass the arrays with regular JDBC connection. If I run the same piece of code using a connection recieved from the datasource of weblogic server, its not working. I am getting serialization errors with the ArrayDescriptor class. Looks like the ArrayDescriptor is not serializable.
Does anybody know solution/workaround to pass arrays ?
Thanks in advance

you could write a wrapper class that extends ArrayDescriptor and implements serializable...
for example your class would look something like this.
public class MyArrayDescriptor extends ArrayDescriptor
implements Serializable
in your regular code use the wrapper class in place of the ArrayDescriptor (it will contain all the same methods as the real ArrayDescriptor) and you should be able to toss your wrapper class anywhere you please.

Passing parameters to oracle stored procedure in business objects universe

Hello,
Wanted to create a web intelligence usind oracle stored procedure.
Create the following SP
create or replace procedure proc_name1
    proc_freq in number,
    proc_cur1 in out sys_refcursor
as
begin
    INSERT INTO
            cc    VALUES
            ( 'Frequency Value = ' || proc_freq, SYSDATE) ;
    COMMIT ;
    --daily
        if(proc_freq = 2) then
        open proc_cur1 for SELECT
                    EVENT_DATE
                FROM rqm_mapsigng_dly_stats;
        end if;
end;
tried using the above SP in universe, it is needed to pass the parameter for proc_freq, when i pass value 2 , in oracle it is passed as 0(is being traced in rqm_checkpoint table)
Hence the table cannot be inserted in the universe.
Can anyone tell why the value is not being passed correctly

I believe when you're doing it with an insert, you're saying "execute this insert statement a bunch of times, here's all the values in advance", which is different than passing an array to a stored procedure where you want it to execute once.
Oracle's ODBC driver doesnt support Associative Arrays (aka index-by tables).

Passing array to Oracle stored procedure

Is it possible to pass an array (TYPES.Array) to an oracle stored procedure in WLI? I know it can be done in vanilla jdbc.
I have tried to do this but I'm getting this exception:
java.sql.SQLException: Fail to convert to internal representation:

Well well well......I was able to fix the same.
The implementation for writeSQL is the catch. We need to give the conversion only in that.
Anyway, thanks.

Pass array to oracle stored procedure

I have such a problem: I have to pass array to stored procedure, so I declare type:
create type tNumberArray as table of number
and create procedure:
create or replace procedure proc_1 (in_param in tNumberArray) as
.... BODY OF PROCEDURE ...
when I call this procedure from C# like this:
int []pParam = new int[3] {1,2,3};
OracleCommand cmd = new OracleCommand("proc_1", dbConn);
cmd.CommandType = CommandType.StoredProcedure;
OracleParameter param14 = new OracleParameter("param", OracleDbType.Decimal);
param14.Value = pParam;
param14.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
param14.Size = 3;
param14.Direction = ParameterDirection.Input;
cmd.Parameters.Add(param14);
cmd.ExecuteNonQuery();
an error occures. It say that there invalid number or type of parameters.
But when I declare both type and procedure in a package everything goes fine.
What is the matter? Did anybody have the same problem?

Not I got next problem:
when I cannot pass parameter to stored procedure and get array fro it. In other words returning array from procedure and passing some input parameters to it does not word!
Does anybody know why it happens?

Passing XMLType Data into oracle stored procedure using JDBC

Hi Friends,
I have requirement where my oracle stored procedure accepts XML file as an input. This XML File is generated in runtime using java, I need to pass that xml file using JDBC to oracle stored procedure. Please let me know the fesibile solution for this problem.
Following are the environment details
JDK Version: 1.6
Oracle: 10g
Server: Tomcat 6.x
Thanks in Advance

A 'file' is a file system entity. There is no way to pass a 'file' anywhere. Not PL/SQL. Not java.
Now you can pass a file path (a string) in java and to PL/SQL.
Or you can pass xml data (a string) in java and to PL/SQL. For PL/SQL you could use eithe a varchar2, if the xml is rather small, or a blob/clob.

How to Pass parameters to Crystal report 10 based on Oracle Stored Procedur

Hi,
I use the following code to pass the parameters:
Rep.Tables[0].ConnectBuffer := Connection_Str;
Rep.Tables[0].AliasName := 'REP';
Rep.Connect.Propagate := True;
Rep.ParamFields.ByName('Lang', '').CurrentValue := IIF(BiDiMode = bdRightToLeft, '2', '1');
Rep.ParamFields.ByName('SESSION_ID', '').CurrentValue := IntToStr(Session_id);
Rep.WindowState := wsMaximized;
Rep.Show;
The 1st parameter 'Lang' which created from crystal report pass well,
but the 2nd parameter 'SESSION_ID' which created from Oracle Stored Procedures give the following Error:
Error: 202 Parameter Name could not be found u2013 ParamFields.ByName
However in MS SQL Server the above code work fine with the 2 Parameters.
Any one has solution,

Hello,
Click on the businessobjects Tab above and then select Samples and dowload the sample app you for your SDK. There are a few samples for changing/setting Parameters.
The Parameter collection has all parameters.
Thank you

Passing Arrays of User Defined Types to Oracle Stored Procedures

Hi
I am using WebLogic 8.14 & Oracle 9i with thin JDBC driver.
Our application needs to perform the same DB operation for every item in a Java Collection. I cannot acheive the required performance using the standard Prepare & Execute loop and so I am looking to push the whole collection to Oracle in a single invocation of a Stored Procedure and then loop on the database.
Summary of Approach:
In the Oracle database, we have defined a Object Type :
CREATE OR REPLACE
TYPE MYTYPE AS OBJECT
TxnId VARCHAR2(40),
Target VARCHAR2(20),
Source VARCHAR2(20),
Param1 VARCHAR2(2048),
Param2 VARCHAR2(2048),
Param3 VARCHAR2(2048),
Param4 VARCHAR2(2048),
Param5 VARCHAR2(2048),
and we have defined a collection of these as:
CREATE OR REPLACE
TYPE MYTYPE_COLLECTION AS VARRAY (100) OF MYTYPE
There is a stored procedure which takes one of these collections as an input parameter and I need to invoke these from within my code.
I am having major problems when I attempt to get the ArrayDescriptor etc to allow me to create an Array to pass to the stored procedure. I think this is because the underlying Oracle connection is wrapped by WebLogic.
Has anyone managed to pass an array to an Oracle Stored procedure on a pooled DB connection?
Thanks
Andy

AndyHi. Here's what I suggest: First please get the JDBC you want to work in a
small standalone program that uses the Oracle thin driver directly. Once
that works, show me the JDBC code, and I will see what translation if
any is needed to make it work with WLS. Will your code be running in
WebLogic, or in an external client talking to WebLogic?
Also, have you tried the executeBatch() methods to see if you can
get the performance you want via batches?

Not able to get Oracle stored procedure return value passed to Powerbuilder

I have an Oracle Stored Procedure that receives a string value and returns a string value.. When I call it from Powerbuilder, it executes but does not send the return value of a string back. I am trying to encrypt a string in Powerbuilder, pass it to a .net web page and then decrypt so I can check the security tables for permissions to view the web page. I have tried creating a simple stored procedure that takes a string and returns a string to Powerbuilder; but even that is not working. Any suggesstions?
Oracle Procedure:
CREATE OR REPLACE
PROCEDURE               TESTINOUT_VARCHAR
( P_STRING IN VARCHAR2, P_OUT OUT VARCHAR2)
IS
   BEGIN
      P_OUT := P_STRING || 'TESTING';
END TESTINOUT_VARCHAR;
Powerbuilder Call:
string p_string ='                                 '
Declare TestingString procedure for TESTINOUT_VARCHAR(:ls_group, :p_out) using SQLCA
Execute TestingString;
IF SQLCA.CODE = 0 THEN
FETCH TestingString into:p_out;
End If
p_string = p_out;

Hello John,
I'm not sure if you already found a solution using an ODBC connection.
Below the solution with an RPC call:
Create a user object (uo_trans) of type transaction with the following local external function:
subroutine TESTINOUT_VARCHAR(string P_STRING,ref string P_OUT) RPCFUNC
Execute this script
uo_trans l_transaction
string ls_outparam
l_transaction = CREATE uo_trans
// Profile ODBC_ORA
l_transaction.DBMS = "ODBC"
l_transaction.AutoCommit = False
l_transaction.DBParm = "ConnectString='DSN=ODBC_ORA;UID=system;PWD=<xxxxxx>'"
connect using l_transaction;
ls_outparam = space (30)
l_transaction.testinout_varchar( sle_1.text, ls_outparam)
messagebox("OUT parameter", ls_outparam)
disconnect using l_transaction;
DESTROY l_transaction

Passing DATE parameters to Oracle Stored Procedures using ADO

Does anyone know how can I pass a date parameter to an Oracle
Stored Procedure? The IN parameter of the procedure is of type
DATE and the ADO parameter is of type DBDate (I've tried Date
and DBTimeStamp,too). The execution freezes at "Cmd.Execute".
Can anyone suggest a solution?
Thanx for any tips

As far as I know the documentation on CR & stored procedures says that the REF CURSOR has to be a strongly bound one.
Could you go into a little more detail? Do you mean I should put a multi-valued parameter into a REF CURSOR? Can you post some code snippets here?

Passing an array of structures to an Oracle stored procedure (CFMX)

I'm looking to write a Oracle stored procedure where I would pass in an array of structures and loop over each iteration to insert the bits and pieces within the structures to the DB.,
I haven't written this type of procedure / package before. I am planning to do an sp / package similar to what is sketched out in the second reply to this thread: http://forums.oracle.com/forums/thread.jspa?threadID=1078772
Assuming I do, how can I call the procedure from ColdFusion (I'm using MX) and pass in my array? As far as I can see, none of the CF_SQL_Types make sense.

Let me know if you make any progress. I'm fighting the same battle. What I've done so far is to convert my array of struct into a delimited CLOB that looks like this:
prop1;prop2;prop3|prop1;prop2;prop3|prop1;prop2;prop3|prop1;prop2;prop3|
Then I wrote a stored proc to suck it up using a pipelined function. It's not to bad but parsing the CLOB on the ORACLE side is somewhat time consuming.
I've also converted the array to XML and used dbms_xmlstore to convert but, on large arrays, it is very slow and the CLOB gets huge fast.
I was hoping to use the cf_sql_refcursor but I can't figure out how.

Create Oracle BLOB and Pass to Oracle Stored Procedure

Hi All,
I am using Oracle 10g and am dealing with a requirement where I have to upload a file to Oracle Portal from the client's local machine using a JSP.
I am planning to convert the text file to a BLOB and pass it to an Oracle stored procedure which does the rest.
I am unable to create a BLOB object. Can anybody help me with this please.
Is there a better alternative to do it?
Thanks in advance,

u can create blob as below...
java.sql.Blob blob=new Blob();
File file=new File(fullPathTo UrFile);
FileInputStream fInSteam = new FileInputStream(file);
BufferedInputStream bInputStream = new BufferedInputStream(fInSteam);
ByteArrayOutputStream bOutputStream = new ByteArrayOutputStream();
int nextByte;
while (( nextByte = bInputStream.read() ) != - 1)
bOutputStream.write(nextByte);
byte[] byteContent = bOutputStream.toByteArray();
blob.setBytes(byte[]);
i think it should work for u...

How to pass values to Oracle store procedure in Crystal Report

Hi all,
I am newbie on passing values to stored procedure parameters. I created a Crystal Report using the Crystal Report wiward with PULL method and data come from Oracle stored procedure. In an ASP.NET page, I have stored two values in Session and need to pass them as input parameters to Oracle stored procedure to print the report. In Crystal reports 2010 once you connect to a stored-procedure as data source, it automatically creates the parameter fields with Crytal Report Viewer. Please show me how I pass values to store procedure at runtime automatically.
        'Set the parametter value
        myReport.SetParameterValue("@P_COURSE", "CoursetNo")
        myReport.SetParameterValue("@P_CLASS", "ClassNo")
    End Sub
I tried to apply above codes from Brian Bischof book but display the error from the following lines:
        myReport.SetParameterValue("@P_COURSE", "CoursetNo")
        myReport.SetParameterValue("@P_CLASS", "ClassNo")
I also enclosed my code. Any experts, please let me know anything wrongs on my code . I tried several methods that searching via google, but did not solve my issues. Thanks.
