Sort data in ref cursor

Hello,
I would like to know if the following is possible:
I'm getting data from different sources in a ref cursor. Is it possible to sort this ref cursor on a specific column in the ref cursor? If so, how?
Thanks
Karuna

My problem is ...
I take the ref cursor, and have added some more data in there, based on a few conditions from different tables. So my ref cursor actually has more relevant data as compared to its source. I now need to find a way to sort that info. Is there a way around this?
Thanks
Karuna

Using CRUD procedures to update data and ref cursors to return data

Hi:
I am currently evaluating Apex 3.x to replace an existing app that uses lots of procedures to update and return data.
1. Is it possible to return data from a function that returns a cursor (or from a procedure that has an input/output ref cursor parameter for that matter) ? Example: Let's say I have the following function in a package:
function get_data return sys_refcursor
is
l_cursor sys_refcursor;
begin
open l_cursor for select sysdate as field from sys.dual;
return l_cursor;
end;
Can I add a page with a table that is populated based on this function? Based on my research it is not possible, but I want an APEX expert to confirm it
2. The old application uses CRUD procedures to update date, that is for each table there are 3 procedures, insert update and delete. Question: is it possible to channel all the update, inserts and deletes through these procedures? Furthermore, in lots of cases I use sequences to populate the primary keys, and the new value is returned as output parameter. Can I retrieve the output value and use it maybe in the next page I am branching to?
In the samples that I've seen the same form is used for insert and update. How do I distinguish between the two modes?
3. Can you please point me to some samples that show how to do 1 & 2. The standard samples that I've seen use the automatic row processing.
4. Could you please recommend some good books about Apex or HTML db? I found the documentation unintuitive. It is hard to picture quickly how things tie together by reading this documention. I wish the documentation was more task oriented and presented 'how to...' implement generic patterns used in web apps.
Thank you in advance

Missing data in ref cursor

I've got a procedure in PL/SQL that returns data to a .NET program using a ref cursor. If I run the procedure, all the data shows correctly. However, when I run it from .NET, it drops two records entirely (they are blank) and another one has "SYSTEM.WINDOWS.FORMS.TEXTBOX, TEXT" before the data prints. I'm passing the date as part of a string, using to_char to convert it.
The two lines that are missing are address lines (street address is one and city/state/zip is the other). The person's name (which is the first line) shows up fine. The street address starts with a number.
I'm passing all the fields as varchar2s.
On the .NET side, here's my code to populate the dataset:
Dim da As OracleDataAdapter = New OracleDataAdapter(cmd)
Dim ds As DataSet = New DataSet
Try
da.Fill(ds, "Bill")
When I look at the resulting data, the address lines are blank and the field with the date is showing the "SYSTEM" shown above.
Anyone have any ideas? This is driving me crazy.
-Joe

As a followup, I think the "SYSTEM.WINDOWS.FORMS.TEXTBOX, TEXT" problem has to do with how the parameter is passed. I'm asking the user to enter a date and then pass it as a varchar2. The parameter in my procedure is a varchar2 also. It is passed correctly and comes back correctly, but it puts the "SYSTEM.WINDOWS.FORMS.TEXTBOX, TEXT" before it prints the date. If I hard code the date in my PL/SQL procedure, it passes perfectly and prints perfectly. So it must be coming from .NET to Oracle. I've tried converting it to a date and then back to text, but with the same result.

Sorting the results returned by a Ref cursor

Hi All,
I have a scenario where i am asked to sort results returned by a ref cursor.
I have to pass the column to be sorted as the Input parameter to a stored procedure. I tried using 'order by sorting_parameter' in the ref cursor's select query, but it is not sorting the results. It is not throwing any error even.
Please help.
Many Thanks...

No. You could sort the data in the SQL statement from which the REF CURSOR was created, but once you have a REF CURSOR, you cannot do anything but fetch from it.

So, the results from a ref cursor cant be sorted?? There is no way out?
Kindly advise.

How to update data returned using REF CURSOR

Hi all,
I am trying to update updated data in a gridview but the update button seem to do nothing as i retrieve data using REF CURSOR.
Let me describe the architecture of my application first. I'm trying to implement best practice whenever possible. I am following the data access tutorial published in www.asp.net , the only difference is that i have an Oracle (10g) database. So I split my application into three layers, data access, business logic, and presentation layer. I'm also writing all queries in an Oracle package.
So I have my Oracle packages that perform CRUD operations. Then I have an xsd file that define dataTable based on the package procedure. My business logic layer then calls functions defined in the xsd file. And finally a detailsView control that uses an ObjectDataSource to call business logic functions.
In a nutshell, I am just trying to update records retrieved using REF CURSOR. Your help is very much appreciated. Please let me know if further details are required. Cheers,

In the DataSet (xsd) where your DataTable is defined, you just need to add additional methods to the TableAdapter to handle insert, update and delete, either with SQL or by mapping to stored procedures.
Alternatively in code, create an OracleDataAdapter and supply its InsertCommand, UpdateCommand and DeleteCommand.

Hyperion get ref cursor data

Hi,
Is there any way to execute stored procedure via hyperion using ODBC and get back ref cursor data.
I tried to call a stored procedure that have a ref cursor out parameter but it gives me error.
My stored procedure code is below.
wrong number or types of arguments to in call to 'HYP_CURSOR'
create or replace package hyp_ref_cusrsor is
type t_cusror is ref cursor;
end;
create or replace procedure hyp_cursor(ret1 out hyp_ref_cusrsor.t_cusror) is
begin
open ret1 for select * from hyp_tmp1 m;
end;
Hyperion version is 9.3.1
Oracle version is 10.0.2

Re: OPEN cursor for large query
A ref cursor is a pointer to a compiled SQL statement, it has no rows so there is no limit to the number of rows that you can use it to fetch, just like there is no limit to the number of rows a select can return.
I am using a ref cursor to return data and testing using toad, it hangs the session. My Business Object report also hangs because of the large data volume 750,000 rows returned via a ref cursor. This is very confusing, it it hangs how do you know it returns 750,000 rows?

Ref Cursor Data Volume

Is there a limit to the volume of data a ref cursor can return via an Oracle Database Procedure call? I am using a ref cursor to return data and testing using toad, it hangs the session. My Business Object report also hangs because of the large data volume > 750,000 rows returned via a ref cursor.
The database procedure works fine when the number of rows is less than 2,000.
Has anyone had this problem before?
Many Thanks,
Georgie

Is BC4J a viabl option for database with stored procedure (ref cursor) API?

I'm about to begin a Web application development project. As foundation, we have a (Oracle) database of certain complexity that have a data access API developed with PL/SQL packages.
This API is designed to get data through stored procedures/functions that return REF CURSOR.
Personally I have been investigating about Oracle ADF/JSF, and a number of others J2EE technologies, and at this moment I am doubting if ADF BC are a viable option to my development team.
I think this because I have noticed that one of the great drawback in ADF BC is the lack of simplicity to get data through stored procedures/functions that returns REF CURSORS.
I have been looking for documentation and the only thing that I have found are two examples:
1.- One that really do not work (fails in get data from ref cursor): ADF BC StoredProcedure Sample application.
2.- And other published by Steve Muench in
http://radio.weblogs.com/0118231/stories/2003/03/03/gettingAViewObjectsResultRowsFromARefCursor.html. This sample works fine.
But, the problem with the approach of this last article is the amount (and complexity) of the code necessary to make so basic and recurrent operation as is "obtain data through a stored procedure (ref cursor)".
Below it is the code that I have constructed to call a function that returns a ref cursor (based on steve's article).
If this is the only way to make this (historically so basic and simple) task, then it is obvious that BC is not a viable technology to my (or I am in a mistake?), since we have about 50 stored procedures/functions to access the underlying data; that stored procedures/functions are key to development of the new application (and, still more, currently are used to anothers apps ).
By all this, I would like consult to Oracle's people:
1.- I really must reject BC as technology to implement this project ?
2.- It is possible to access stored procedures in a simpler way using BC?
3.- If the answer to 2 is NOT: in near future, the BC team has plans to give more support to the simple access to stored procedures?
4.- If the answer to 3 is NOT: what another technology you recommend to construct my data access/business tier and still be able to using the others characteristics of ADF?
Thank you very much for your guidelines.
Regards, RL.

To test ref cursor.

I have following package specification ,
create or replace
PACKAGE "DATA_LKUP"
IS
TYPE BILL_POL IS RECORD
(v1 NUMBER,
V2 NUMBER,
V3 VARCHAR2(30))
TYPE R_POL_RC IS REF CURSOR
RETURN BILL_POL;
PROCEDURE P_GET_BEN_POL(V_ref_coursor IN OUT R_POL_RC,
N_KEY1_IN NUMBER,
N_KEY2_DT_IN NUMBER,
               N_VAR OUT NUMBER);
END;
I have to write one general script to test procedures like P_GET_BEN_POL,
which has ref coursor as OUT parameter. I can write SQL script in following way.
DECLARE
T1 NUMBER;
T2 IS REF CURSOR;
BEGIN
DATA_LKUP.P_GET_BEN_POL(t2,1,2,t1);
dbms_output.put_line('Data 1 ==>>'||t1);
END;
But how do I test output variable T2, How do I print it? or is there any way to know structure of t2 so that I can print data of
ref cursor in following foramt?
Data:
col1 col2 col3 col4
as if I don't know package specification code.
I want to design such sql test scripts in general way, to test above procedures.

You can build upon this example:
SQL> create or replace procedure test_refcur(rc OUT sys_refcursor) is
2 begin
3    open rc for select * from scott.emp ;
4 end ;
5 /
show errors
variable rc refcursor
exec test_refcur(:rc) ;
print rc

Hello InoL,
REF Cursor is working better if it is a Navigator, Toad or SQLPlus.. but it is prompting all sort of errors when it is used within Reports 6i.. Here is what i was trying to achieve..
The purpose of "REF Cursor" is to retrieve multiple parameter values .. ( at least that is what GOOGLE results were about REF Cursor )..
At the same time, a function does not return more then one value and I'm not sure if Reports will allow to use a stored procedure. So, I started to use REF Cursor
"lstvlv_refcur(vlvno OUT v_cursor )" I'm trying to retrieve as I mentioned 9 valve records to one report and remaining valve records to 2nd report, which I'm calling it via SRW reports built-in package..
Here is the latest and greatest code on my REF Cursor..
1) created "global temporary table" one time..
2) within Reports added this package ( as a program unit )
     package vlvlst_chk is
     type vlvlst_rcd is RECORD
     ( fctly_seq_nbr number,
     vlv_nbr varchar2(6));
     type vlvno_refcur is REF CURSOR return vlvlst_rcd;
     end;
3) then added a function called QR_1RefCurDS ( as a program unit )
function QR_1RefCurDS return vlvlst_chk.vlvno_refcur is
hld_vlvlst vlvlst_chk.vlvno_refcur;
fctno INTEGER;
vno varchar2(6);
begin
delete from fct_vlv_hold;
commit;
delete from fct_vlv_hold2;
commit;
open hld_vlvlst for
select r.fclty_seq_nbr,r.vlv_nbr
from REGSTATVLVS r
where r.fclty_seq_nbr = :p_2
order by vlv_nbr;
     for i in 1..40 loop
     fetch hld_vlvlst into fctno, vno;
     exit when hld_vlvlst%notfound;
     if i <= 9 then
          insert into fct_vlv_hold
          values(fctno, vno);
          commit;
--          return hld_vlvlst;
     elsif (i>9 and i<= 40) then
          insert into fct_vlv_hold2
          values(fctno, vno);
          commit;
--      return hld_vlvlst;
     else
return hld_vlvlst;
     end if;
     end loop;
     close hld_vlvlst;
     return hld_vlvlst;
end;
Here: prompts "REP-0065/REP-0200" error, but writes records to temp tables..
Question is why is it prompting this error?

How to fetch NO DATA FOUND exception in Ref Cursor.

In my procedure ref cursor is out parameter with returns dataset. in my proceudre
its like...
OPEN pPymtCur FOR
select.....
when I call this procedure from report to get dataset it causes NO DATA FOUND exception.
How to fetch this exception in my oracle procedure so I can get some other data.
Any Idea to do this?

Correct me if I am wrong.
So if I do something as follows in my stored proc, I do not have to check for NO_DATA_FOUND?
OPEN my_CuRSR FOR
SELECT DISTINCT blah blah blahmy_cursr is what I am returning as OUT param in my SP.Correct. At the point you open the cursor, oracle has not attempted any 'fetch' against the data so it won't know if there is any data or no data. that only occurs when a fetch is attempted.
Take a read of this:

How to retrieve data from a REF CURSOR using OCI 8.0?

I found an example in Oracle docs (shown below) that discusses how to bind a REF CURSOR for later data retrieval, but it does not explain actually how to do the later data retrieval.
I hope someone can explain it to me. Thanks
The OCI provides the ability to bind and define PL/SQL REF CURSORs and nested tables. An application can use a statement handle to bind and define these types of variables. As an example, consider this PL/SQL block:
static const text plsql_block = (text )
"begin \
OPEN :cursor1 FOR SELECT empno, ename, job, mgr, sal, deptno \
FROM emp_rc WHERE job=:job ORDER BY empno; \
OPEN :cursor2 FOR SELECT * FROM dept_rc ORDER BY deptno; \
end;";
An application would allocate a statement handle for binding, by calling OCIHandleAlloc(), and then bind the :cursor1 placeholder to the statement handle, as in the following code, where :cursor1 is bound to stm2p. Note that the handle allocation code is not included here.
err = OCIStmtPrepare (stm1p, errhp, (text *) nst_tab, strlen(nst_tab),
OCI_NTV_SYNTAX, OCI_DEFAULT);
err = OCIBindByName (stm1p, (OCIBind **) bndp, errhp,
(text *)":cursor1", (sb4)strlen((char *)":cursor1"),
(dvoid *)&stm2p, (sb4) 0, SQLT_RSET, (dvoid *)0,
(ub2 *)0, (ub2 *)0, (ub4)0, (ub4 *)0, (ub4)OCI_DEFAULT);
In this code, stm1p is the statement handle for the PL/SQL block, while stm2p is the statement handle which is bound as a REF CURSOR for later data retrieval. A value of SQLT_RSET is passed for the dty parameter.

( sorry, i forgot the Link where i get this html fiLes, so i just copy-paste here )
( maybe it can heLp you a bit. -- it's heLp me, for sure )
And the following is thanks to Brett Rosen :
I noticed that you didn't have an OCI entry
on http://osi.oracle.com/~tkyte/ResultSets/index.html .
Here is OCI code to do this (Oracle 81) if you want to include it on
that page.
Some error checking and cleanup has been removed, but the below should
work. (once dbname has been replaced appropriately)
