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.

Getting resultset from stored procedures..

hi all,
i have got some very fundamental doubts regarding Oracle Stored Procedures and calling it from java.. i want the resultset to be returned from sp and for that i used to following sp and java code.
package
====
CREATE OR REPLACE package
curs_types as
type EmpCurType is REF CURSOR RETURN emp%ROWTYPE;
end curs_types;
procedure
======
procedure
single_cursor(curs1 IN OUT curs_types.EmpCurType)
AS
BEGIN
OPEN curs1 FOR SELECT * FROM emp;
END single_cursor;
java code for calling sp
=========
String sql = "{call single_cursor(?)}";
CallableStatement cstmt1 = con.prepareCall(sql);
cstmt1.registerOutParameter(1, OracleTypes.CURSOR);
cstmt1.execute();
rs = (ResultSet)cstmt1.getObject(1);
while(rs.next())
{ String empno=(String)rs.getString(1);
and it worked properly but the problem is i dont want all the fields from the table emp..i mean, if i change the query inside the sp from "select * from emp" to "select ename,empno from emp" then that sp is showing compilation errors.. is it possile to return a cursor from sp that contains specific fields ??
wat is the procedure to return a cursor that contain datas from multiple tables ???
can any1 help me with this ??? plz mail me on [email protected]
thanks in advance

Yes. See your Oracle docs.

How to get a resultset from Stored Procedures

How to efficiently and portably get resultsets from Oracle stored procedures? Oracle does not seem to follow JDBC standards here. A standard way in Oracle is to use a ref cursor and call getObject() on CallableStatement. However, Oracle seems to get all the data in the resultset in getObject(), which is inefficient and leads to large memory usage when the resultset is large.
Another way in Oracle is to use getCursor() on an OracleCallableStatement, which is efficient but not portable across different application servers. For example, in WebSphere, this OracleCallableStatement is not available if we want WebSphere to manager the datasource.
Any ideas will be greatly appreciated. Please email to [email protected]

Oracle JDBC did not support return a result set, if you are using Oracle 9i, you can use pipeline function, then using the TABLE() function the get the row.
Good Luck.

Returning Oracle Output Parameters from Stored Procedures

Hi,
Please forgive my ignorance of Oracle and PL/SQL. I'm trying to get a value out of a stored proc which I've written. The proc takes a username input parameter and returns a user guid through an output parameter. I'm able to print the output parameter to the DBMS Output but can't figure out how to return the thing in a record when calling the proc through a normal sql prompt!
My call is like so:
DECLARE
nGUID NVARCHAR2(255);
BEGIN
GETUSER(nGUID, 'WHY-DEV-QSYS-Tim Watson');
DBMS_OUTPUT.PUT_LINE (nGUID);
Would like to return the value here; what's the syntax?
END;
The signature of the proc is
CREATE OR REPLACE PROCEDURE GETUSER
USERGUID OUT NVARCHAR2,
UNAME IN NVARCHAR2
IS
Can anyone assist?
Thanks in advance!
Tim

The easiest way, in my opinion, is to not write a procedure, but a function for this porpose. You would not have to declare an out parameter, but a return value:
CREATE OR REPLACE FUNCTION GETUSER
UNAME IN NVARCHAR2
return nvarchar2
IS
From SQL prompt, you can then do
SQL> select getuser(<input_string>) from dual;
and get the returnvalue.

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.

Using XI - RFC table and an Oracle stored procedure that returns a cursor.

I need to create an interface using XI between an RFC table and an Oracle stored procedure that returns a cursor. We are on oarcle 9.2 and SP12.
My stored procedure looks something like this:
CREATE OR REPLACE
PROCEDURE testproc_xi2 (p_recordset1 OUT SYS_REFCURSOR,
 in_quoteid IN varchar2 )
AS
BEGIN
OPEN p_recordset1 FOR
 SELECT q.quote_id,
 q.modified_by,
 q.quote_status,
 q.total_cost
 FROM quote q
 WHERE q.quote_id = in_quoteid
 AND q.total_cost > 0 ;
END testproc_xi2 ;
My RFC has table and one import parameter .
I wanted to know how to create the data type for the ref cursor? and also for the table type in the RFC?
CAN XI handle multi rows coming from a Stored procedure? Are there any other alternative methods if this is not supported?Any pointers to this would be helpful.
I have called a Oracle SP from an RFC before, but that interface had one input parameter going to the stored procedure from the RFC and about 6 o/p parameters coming from the Stored procedure. This works fine.
Thanks for the help.
Mala

Mala,
i dont think there is anything called an rfc table...RFC stands for remote function call. That in essence would imply you need a rfc to jdbc connection.
yes XI can handle multiple rows cooming from the the stored procedure if you have them mapped appropriately.
Now as to how to create the data type within xi , you need to know what fields are going to be returned and whether they are nested and then just create them as you would for an xml
for ex
<Details>
<FirstName>
<LastName>
</Details>
that in xi would be smthing like
Details type of data occurence
FirstName type of data occurence
LastName type of data occurence.
Hope that helps.
If it does dont forget the points..:-)

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
Field1 Field2 Field3
A 1 3
B 1 5
C 2 10
Table DEF
Field1 Field2 Field3
D 10 24
E 3 16
F 8 19
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.

Shruti

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...

Java and Sybase nested stored procedures.

Hi!
I have nested Sybase stored procedures, the main procedure calls a helper stored proc.
The main procedure returns 2 result sets before calling the helper store proc and helper store proc returns 1 resultset. After the helper store proc is called, the main store proc returns 2 more resultset. When I run it using SQL client tool the main procedure(and it's helper) execute well and returns rows.
I need to call this store proc in a java code and display all the resultset in screen. I am using Statement:execute(<exec sp>) to execute the store proc and then statement.getResultSet() to get each resultset. The loop is controlled by statement.getMoreResults() .
It displays the first 2 resultsets from main Store Proc. Then the control goes to helper store proc. It executes the helper store proc and displays the resultset from helper. But then it stops there and doesnot
come back to main store proc to execute the remaining resultset.
What I suspect is that, the statement object is getting overlaid when the call goes to helper proc.
Any idea as to how to code to handle multiple nested resultset ?
~ RNS.
My Sybase stored procedure code looks like -
=======================================================================
create procedure main_proc
@param1 int
as
select getdate()
select @@servername
declare @return_val int
exec proc2 @param1, @return_val out
select myCol1,
myCol2,
myCol3=@return_val
from mytable
select db_name()
===========================================================================
Sybase Code for proc2
create procedure proc2
@param1 int,
@param2 int out
as
begin
if something exists(select * from table where whereClause)
select @param2="TRUE"
else
select @param2="FALSE"
select getdate()
end
go
GRANT EXECUTE...
EXEC sp_procxmode 'dbo.proc2,'unchained'
go
====================================================================
Code snippet :-
do {
int iit=0;
rs=stmt.getResultSet();
if ( rs != null ) {
ResultSetMetaData rsd = rs.getMetaData();
int nocols = rsd.getColumnCount();
for (int i=1; i<=nocols; i++)
System.out.println(rsd.getColumnName(i)));
while (rs.next())
for (int i=1; i<=nocols; i++)
System.out.println(rs.getString(rsd.getColumnName(i));
} while (stmt.getMoreResults());

I'm not 100% sure about this, but my guess is that this is caused by the TDS protocol (used by Sybase). TDS makes no difference between the stored procedure you are calling and the "inner" stored procedure, so the driver just returns update counts and result sets as they are generated, regardless of who generated them.
Another guess (as I don't know what driver you are using) is that execute() returns the first result (update count or ResultSet), as opposed to executeQuery(), which returns the first ResultSet (probably discarding the update count). You can make sure of this by calling getMoreResults(); you should get your ResultSet at some point.

How to generate a report from stored procedure

I would like to generate a report from stored procedure.
I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure.
The resule can be displayed on the development IDE, like sql developer or consume by Java JDBC client.
is there equivalent way to do this in Oracle stored procedure?

Hi,
What type of report you are looking..for.. ??
As you said that "I used to work on sql server. this can be done as easy as put a select statement at the end of stored procedure. "
When you execute it will return the result set and you will display directly on the FrontEnd.. Is my Understanding is correct Up to here.
See, In oracle you have call some custom stored procedures as you did in SQL Sever, but you have return the Results Sets, with help of Out put paramter, Either Cursors or Varrays..
or Else you can generate the Html reports based on your requirement, HTML can be used in the stored procedures of Oracle which will generate for your, you need to code it.
I could not able get the relevant link for your reference.
I will get back to you on this.

Best method to transfer large strings (XML data) to/from stored procedure

Hi!
I'm trying to call a PL/SQL procedure from Java. The procedure inputs a string (XML) that is parsed, and returns a result string (also XML).
Typical size of the string is 5kb -> 1mb.
I can see two possible solutions:
1) String / LONG
2) CLOB (Using DMBS_LOB.createTemporary and getting a CLOB locator and passing the locator to the stored procedure)
Does anyone have other suggestions?
What is the fastest method for transferring XML structures from to and from stored procedures?
Anders

Anders,
I would say it depends on your requirement. Both the methods have some advantages and disadvantages.
Using a CLOB means that you have to use vendor specific libraries but this is more extendible and I fast too.
Using String/Long will be more portable in the long run but again you lose on speed/performance.
Just a doubt of mine... If I got it correct, you are transforming one XML to another XML based on some conditions. Why dont you use XSL and XSL StyleSheet Processor packaged with XDK for this? I think this would be the fastest way.
Hope this helps.

Return a record set from a procedure

I am building an application for my company.
Before oracle I had used MS SQL Server for a long time.
I build a procedure as following
CREATE OR REPLACE PROCEDURE YBP.ReturnSet
-- Return a record set from a procedure
IS
BEGIN
SELECT * FROM fdbase;
END;
But the complier show me a error message:
PLS-00428 an INTO clause is expected in this SELECT statement
I read the error details
"In PL/SQL, only a subquery is written without an INTO clause."
But I know that this procedure can run well in MS SQL Server .
How I can do this thing in Oracle
Any help will be appreciate!
