Returning object from stored procedures

I am having a lot of trouble finding an example to demonstate how I return a Java/DB Object from a Java Stored Procedure. All the examples I have been able to find return one of the native types (VARCHAR, NUMBER, etc). As an example...
public static DataPoint getPoint() {
  return new DataPoint(
      new Timestamp(System.currentTimeMillis()),
      new BigDecimal(50.0));
Assuming DataPoint is a Java class mapped to an Oracle Data Type created via the following statement.
create or replace type data_point as object (
  p_date date,
  p_data number
After loading and publishing the procedure I get no (zero, 0) rows returned when calling. I should be getting one row returned.
Thanks,
Mike

Mike,
You said:
Assuming DataPoint is a Java class mapped to an Oracle
Data TypeI think your assumption is incorrect.
In any case, isn't this what "TopLink" is used for?
(I don't know, since I don't use "TopLink".)
Have you tried the TopLink/JPA forum?
Good Luck,
Avi.

Unable to create object from stored procedure universe

Dear All Experts,
I am facing a problem on unable to create object dimensions on a Stored procedure universe. Fyi, I have successfully insert a stored procedure ('SP_Sales') with input parameter (@date) into universe (Universe_1). But I unable create any object based on the the stored procedured ('SP_Sales') due to it show nothing from the Edit Select Statement of 'Object1', empty for Tables nd columns windows.
Thefore, i unable to drag data in WEBI when i select univese as "Universe_1", it will not sure any object. Please advise.
I am using XI4.0, MSSQL2008.

Hi ,
You wont be able to edit the object definitions.
u2022 Designer generates one table per selected stored procedure (or many
tables if multiple result sets) and one object per column returned by a
stored procedure.
u2022 The result set structure is determined when you describe the function.
Please refer chapter 7(Page 451) of below document for more details.

Ora-06550 returning data from Stored Procedure and Entity Data Model

Hi.
I'm creating an application that uses a WCF Service to return data. I also created a proyect with the EDMX design and mapped most of my DBModel to a classes context. I have added some of the procedures as well. One of them receive some parameters and return a Sys_RefCursor, that is populated according to the parameters.
I have declared the "<add >" tags in the Web.Config and imported the function of the Procedure. When I call the Asyncronous function I get different exceptions:
1. If I call the function, with all of the parameters i get:
Oracle.DataAccess.Client.OracleException: ORA-06550: línea 1, columna 8:
PLS-00306: número o tipos de argumentos erróneos al llamar a
'SP_HECHOSJURITER'
ORA-06550: línea 1, columna 8:
(wrong number or types of arguments in call to 'SP_HECHOSJURITER')
2. If i just set 1 parameter in the SP, returning the same type of data, I get:
Error al recibir la respuesta HTTP a
http://localhost/Procalculo.CGFM.SIGOC.DatosServices/ServiceDatos.svc.
(failed to receive http response. error 12152)
3. If I don't set any parameters in the procedure, it works fine, and return correct data.
It exclusively happen with one entity.
Any clue?
I appreciate any help.

When you return result sets from stored procedures to Entity Framework, you are very likely using implicit result sets. Implicit result sets don't need to be declared as a parameter in code, only in the <add> tags to define the metadata in the .NET config file.
For example, in the EF Oracle By Example, you'll see that the stored procedure in the function import has three parameters, but only two are declared in the code. The third one was defined in the config file.

Return records from Stored Procedure to Callable Statement

Hi All,
I am createing a web application to display a students score card.
I have written a stored procedure in oracle that accepts the student roll number as input and returns a set of records as output containing the students scoring back to the JSP page where it has to be put into a table format.
how do i register the output type of "records" from the stored function in oracle in the "registerOutParameter" method of the "callable" statement in the JSP page.
if not by this way is there any method using which a "stored function/procedure" returning "record(s)" to the jsp page called using "callable" statement be retrieved to be used in the page. let me know any method other that writing a query for the database in the JSP page itself.

I have a question for you:
If the stored procedure is doing nothing more than generating a set of results why are you even using one?
You could create a view or write a simple query like you mentioned.
If you're intent on going the stored procedure route, then I have a suggestion. Part of the JDBC 2.0 spec allows you to basically return an object from a CallableStatement. Its a little involved but can be done. An article that I ran across a while back really helped me to figure out how to do this. There URL to it is as follows:
http://www.fawcette.com/archives/premier/mgznarch/javapro/2000/03mar00/bs0003/bs0003.asp
Pay close attention to the last section of the article: Persistence of Structured Types.
Here's some important snippets of code:
String UDT_NAME = "SCHEMA_NAME.PRODUCT_TYPE_OBJ";
cstmt.setLong(1, value1);
cstmt.setLong(2, value2);
cstmt.setLong(3, value3);
// By updating the type map in the connection object
// the Driver will be able to convert the array being returned
// into an array of LikeProductsInfo[] objects.
java.util.Map map = cstmt.getConnection().getTypeMap();
map.put(UDT_NAME, ProductTypeObject.class);
super.cstmt.registerOutParameter(4, java.sql.Types.STRUCT, UDT_NAME);
* This is the class that is being mapped to the oracle object.
* There are two methods in the SQLData interface.
public class ProductTypeObject implements java.sql.SQLData, java.io.Serializable
    * Implementation of method declared in the SQLData interface. This method
    * is called by the JDBC driver when mapping the UDT, SCHEMA_NAME.Product_Type_Obj,
    * to this class.
    * The object being returned contains a slew of objects defined as tables,
    * these are retrieved as java.sql.Array objects.
     public void readSQL(SQLInput stream, String typeName) throws SQLException
        String[] value1 = (String[])stream.readArray().getArray();
        String[] value2 = (String[])stream.readArray().getArray();
     public void writeSQL(SQLOutput stream) throws SQLException
}You'll also need to create Oracles Object. The specification for mine follows:
TYPE Detail_Type IS TABLE OF VARCHAR2(1024);
TYPE Product_Type_Obj AS OBJECT (
value1 Detail_Type,
value2 Detail_Type,
value3 Detail_Type,
value4 Detail_Type,
value5 Detail_Type,
value6 Detail_Type,
value7 Detail_Type,
value8 Detail_Type);Hope this helps,

You need to have either OUTPUT parameters or use RETURN statement to return a value in stored procedures. RETURN can only return integer values whereas OUTPUT parameters can be of any type
First modify your procedure to define return value or OUTPUT parameter based on requirement
for details see
http://www.sqlteam.com/article/stored-procedures-returning-data
Once that is done in SSIS call sp from Execute SQL Task and in parameter mapping tabe shown above add required parameters and map them to variables created in SSIS and select Direction as Output or Return Value based on what option you used in your
procedure.

OCI8: returning cursors from stored procedures

The short version of my question is:
In OCI8, how do open a cursor from the database stored procedure, return it to my C++ program and fetch from it, given that in OCI8 cursors and cursor functions are becoming obsoleted?
The long version of the same question is:
I am converting my C++ code from the Oracle 7.3 OCI driver to the Oracle8 OCI driver. One thing I did very frequently in Oracle 7.3 OCI code is open a multi-row select cursor within a stored procedure and return that cursor to my program. In the program, I would then do the fetching with the returned cursor. This was very useful, as it allows me to change the queries in the stored procedure (for example, to append information to certain columns or make some data in all uppercase) without recompiling the application due to a changed SQL string.
My 7.3 psuedocode is as follows:
stored procedure def:
TYPE refCurTyp IS REF CURSOR;
FUNCTION LoadEmployeeData RETURN refCurTyp;
stored procedure body:
FUNCTION LoadEmployeeData RETURN refCurTyp IS
aCur refCurTyp;
BEGIN
OPEN aCur FOR
SELECT emp_id, emp_name
FROM employee_table
ORDER BY emp_name;
return aCur;
END;
OCI code: // all functions are simplified, not actual parameter listing
// declare main cursor variable #1 and return cursor variable #2
Cda_Def m_CDAstmt, m_CDAfunction;
// open both cursors
oopen(m_CDAstmt, ...);
oopen(m_CDAfunction, ...);
// bind cursor variable to cursor #2
oparse(&m_CDAstmt, "BEGIN :CUR := MYPACKAGE.LoadEmployeeData; END;");
obindps(&m_CDAstmt, SQLT_CUR, ":CUR", &m_CDAfunction);
// run cursor #1
oexn(&m_CDAstmt);
// bind variables from cursor #2, and fetch
odefineps(&m_CDAfunction, 1, SQLT_INT, &m_iEmpId);
odefineps(&m_CDAfunction, 2, SQLT_CHAR, &m_pEmpName);
while (!ofen(&m_CDAfunction))
// loop: do something with fetch
// values placed in m_iEmpID and m_pEmpName
This works perfectly, and has really helped to make my code more maintainable. Problem is, in Oracle 8 OCI both cursors and the cursor functions (such as oopen()) are becoming obsoleted. Now it uses statement and environment handles. I know I can still use Cda_Def and cursors--for a while--within OCI8, but I need to know the official up-to-date method of returning a cursor from the database and fetching within my C++ code. Any code fragment, or explanation of what I need to do in OCI8 would be appreciated (perhaps I need to bind to a statement handle instead? But the stored procedure still returns a cursor.)
The Oracle8 OCI has a new SQLT_ type, SQLT_RSET, which the header file defines as "result set type". Unfortunately, it's almost completely undocumented in the official documentation. Am I supposed to use this instead of the obsolete SQLT_CUR?
Thanks,
Glen Mazza

Unable to create object from stored procedure

Hi,
we are trying to use a stored procedure to do data preparation.
When we add the stored procedure to a universe, the procedure is executed succesfully and a table with one column, called "1" is created. When we try to create an object from this column, Designer does not allow us to do so.
We already tried to alias the column name in the stored procedure but we still get an unusable column called "1" back.
BO version used is XI R3.0. The stored procedure is written in Cobol on DB2 mainframe.
Does somebody know what we do wrong ?

Problem solved.
First we aliased the result columns in the stored procedure, that got rid of the "1".
Then we still could not create an object based on the column in the result set.
Apparently this issue occurs when the length of the column of the result set is too long.
We decreased the length and now we can create the object

Returning recordset from stored procedures

Hi
I am trying to get a stored procedure to return multiple values (i.e. a recordset) and want to access them from JDBC. Is that possible?
Frankie =:>

You can return nested tables and varrays using JDBC. See chapter 10 of the Oracle JDBC Developer's Guide.

Design Question::Instantiating Object from Stored Procedure Output

Hi All,
I am confused with approaching this design issue. I called a Stored Procedure, and the output from the Stored Procedure is a REF CURSOR. The size of the REF CURSOR can be large.
My Question is, is it a good idea to pass the values from the REF CURSOR to a class constructor, there by instantiating an object of that type. lets say
//rset is of type ((OracleCallableStatement)callableStatement).getCursor(5);
//rset is not ResultType
while (rset.next()){
new ClassXYZ(var1, var2, var3);
/*var1, var2, var3 would be rset.getObject(1),rset.getObject(2),rset.getObject(3)
Class XYZ does some business logic
}Other things:
1) Will the JVM hold up assuming good enough JVM mem size, while creating objects for the range 100 thousands?
2) I do not know the cursor size. It can change randomly from business perspective. And, it would be in the range of 100 thousands
I was thinking, If I can "police" the call to the Class XYZ in case of large data. May be I am totally off the best solution. Any light on the best way to approach will be great.
Anyhow, this would be a standalone java application. Just in case if people are trying to suggest/recommend DAO etc.,
Thank you,
VJ

How to capture return value from stored procedure?

Hi All,
I want to capture the retun values from this procedure to a table - CALL SYS.GET_OBJECT_DEFINITION('SCHEMA_NAME', 'TABLE_NAME').
The below approach is not working -
Insert into STG.STG_DDL
Call SYS.GET_OBJECT_DEFINITION('DWG', 'DWG_SITE')
Could you please have a look on the same?
Thank you,

Returning rowcount and resultset from stored procedure

Hello,
In SQL Server you can return multiple resultsets from stored procedure by simple SELECT statement. But in Oracle, you have to use SYS_REFCURSOR.
Sample code:
CREATE OR REPLACE PROCEDURE sp_resultset_test IS
t_recordset OUT SYS_REFCURSOR
BEGIN
OPEN t_recordset FOR
SELECT * FROM EMPLOYEE;
END sp_resultset_test;
Is there any other way in Oracle 10 or 11 ?
Thank You.

What is the requirement? Oracle is far more flexible than SQL-Server... with numerous features that do not exist in SQL-Server. (Fact)
One of the biggest mistakes you can make is to treat Oracle like SQL-Server... trying to match feature A1 in SQL-Server to feature B3 in Oracle.
Does not work that way.. rather then stick to SQL-Server as SQL-Server does SQL-Server specific features far better than Oracle.
So instead of trying to map what a T-SQL stored proc to do to an Oracle ref cursor (even to the extent of using that very silly sp_ prefix to name the proc), tell us the problem and requirements... That way we can tell you what Oracle features and options are best used to solve that problem - instead of competing in some unknown feature comparison event with SQL-Server.

URGENT : Return Bulk data from Stored Procedure

Hi,
Tell me, how do I return a bulk of data which
does not exist in the data base
but is concluded while the Stored Procedure is executed
from the Stored procedure
to the C++ program.
For Example:
Table ABC

SP_TESTING
Depending on the values in both the tables
for some range of conditions,
a conclusion X is derived for each range value of the
condition range.
Now I need to return this bulk of data X with the
condition they belong to
back to the C++ code calling it....
NOTE : A stored procedure is requited as there is a lot
of processing
required before we conclude the result X for each value
in the condition range.
If I execute this code from C++ instead of Stored
procedure
it is very slow and speed is a prime requirement of my
system.
Also i'm not using any MFC class to access database.
I'm using ConnectionPtr, RecordsetPtr and _CommandPtr
from msado15.dll for database access...
One solution to this could be use of Temp tables.
As this process is used by a lot of different stored
procedures having a common
temp table to all will need something like 50 NUMERIC
fields, 50 VARCHAR fields
and so on, which doesn't seem like a very good solution
to this problem.
Sounds like something I would have done while in school,
implement a dumb solution.
So, please suggest me a solution as to how do I return
bulk data in the form
of recordsets from stored procedure.

Use Out parameter mode

Conversion failed when converting the nvarchar value to data type int when returning nvarchar(max) from stored procedure

Thank you for your help!!!
I've created a stored procedure to return results as xml. I'm having trouble figuring out why I'm getting the error message "Conversion failed when converting the nvarchar value '<tr>.....'
to data type int. It seems like the system doesn't know that I'm returning a string... Or, I'm doing something that I just don't see.
ALTER PROCEDURE [dbo].[p_getTestResults]
@xml NVARCHAR(MAX) OUTPUT
AS
BEGIN
CREATE TABLE #Temp
[TestNameId] int,
[MaxTestDate] [DateTime],
[Name] [nvarchar](50),

, replace(str(Test.TotalTime/3600,len(ltrim(Test.TotalTime/3600))+abs(sign(Test.TotalTime/359999)-1)) + ':' + str((Test.TotalTime/60)%60,2)+':' + str(Test.TotalTime%60,2),' ','0') as Duration

Your dont need RETURN inside SP as you've declared @xml already as an OUTPUT parameter. Also you can RETURN only integer values using RETURN statement inside stored procedure as that's default return type of SP.
so just remove RETURN statement and it would work fine
To retrieve value outside you need to invoke it as below
DECLARE @ret nvarchar(max)
EXEC dbo.[P_gettestresults] @ret OUT
SELECT @ret

Returning SQL cursor from Stored Procedure

Hi,
I have a query regarding returning sql cursor from stored procedure to java in oracle 11g.
I want to query some data ex: my query returns A, B, C. Also, now I want to query some other data ex: D, E, F. Now I want to return this data as an sql cursor as a single row . Example: A,B,C,D,E,F. Is it possible to return/create a cursor in stored procedure?
assume both query returns equal number of rows.. however both are not related to each other..

assume both query returns equal number of rows.. however both are not related to each other..It sounds like what you need is a ref cursor.
First thing to remember though is that cursors do not hold any data (see: {thread:id=886365})
In it's simplest form you would be creating a procedure along these lines...
SQL> create or replace procedure get_data(p_sql in varchar2, p_rc out sys_refcursor) is
2 begin
3    open p_rc for p_sql;
4 end;

Now, as for getting your rows to columns and combining two queries that do that... something along these lines...
