Ref cursor question
Hi,
I have stored proc that takes pl/sql table as IN parameter and returns a ref cursor.
Data from pl/sql table is separated into two table type objects ... oType1 and oType2 based on some condition.
following works fine...
If oType1.Count > 0 then
OPEN list_out FOR
select col1, col2, col3, col4 ..... col20
from TABLE(CAST(oType1 AS obj_table_t)) a,
t1,
t2
where a.colvalue = t1.colvalue
and etc....
UNION ALL
select col1, col2, col3, col4 ..... col20
from TABLE(CAST(oType1 AS obj_table_t)) a,
t3,
t4
where a.colvalue = t3.colvalue
and different conditions etc....
I have 4 UNION ALL's. Had to use this because of different where coditions.
end if..
The problem is with oType2......
If oType2.Count > 0 then
-- getting data from different database using dblink along with values from present database.
-- resultset columns will be same as above
-- Question is how to send these results in same refcursor.
end if;
Thanks for your time.
Hi,
I think that a plsql table is what you want and not a ref cursor. If you have a plsql table based on your user defined type you can keep assigning all the values you want to it and then pass it out of your procedure.

Hello, Tom.
I have one bind variable in a dynamic SQL expression.
When I open cursor for this sql, it gets me to ora-01008.
Please consider:

PL/SQL procedure successfully completed.
And if I run the same thing on 10g -- all goes conversely. The first part runs ok, and the second
part reports "ORA-01006: bind variable does not exist" (as it should be, I think). Remember, there
is ONE bind variable in sql, not two. Is it a bug in 8i?
What should we do to avoid this error running the same plsql program code on different Oracle
versions?
P.S. Thank you for your invaluable work on this site.
Followup June 9, 2005 - 6pm US/Eastern:
what is the purpose of this query really?
but it would appear to be a bug in 8i (since it should need but one). You will have to work that
via support. I changed the type to tarray to see if the reserved word was causing a problem.
variable v_refcursor refcursor;
set autoprint on;
begin
crosstab.pivot (p_max_cols => 4,
p_query =>
'SELECT job, COUNT (*) cnt, deptno, ' ||
' ROW_NUMBER () OVER ( ' ||
' PARTITION BY job ' ||
' ORDER BY deptno) rn ' ||
'FROM emp ' ||
'GROUP BY job, deptno',
p_anchor => crosstab.tarray ('JOB'),
p_pivot => crosstab.tarray ('DEPTNO', 'CNT'),
p_cursor => :v_refcursor);

/Was going to use this package as a stored procedure in forms but I not sure it's going to work now. -
Dynamic Ref Cursor report in 6i
Hello,
I apologise that this question is so similar to many in this forum, but I haven't found a solution to my problem yet.
I've created a ref cursor query because I need to include a variable p_orgs in my WHERE clause, like so:
where e.org_id in ('||p_orgs||')
I've constructed the report as mentioned on this page:
www.dulcian.com
FAQs - SQL & PL/SQL FAQs - FAQ ID# 5:
"How can you use 'dynamic' ref cursors in Oracle Reports 3.0 / 6i?"
(Thanks to Zlatko Sirotic for the information).
I get a compile error when compiling the package body that holds my ref cursor open statement:
Error 103 Encountered the symbol ''select'' when expecting one of the following:
Select
Is there any way around this problem?
If I was to upgrade to Reports 9i would it work?
Many thanks,
HazelHello,
Just a remark : you don't need to use a Ref Cursor if you just want to use a "dynamic where clause".
You can use a lexical reference :
You can find examples at :
http://www.oracle.com/webapps/online-help/reports/10.1.2/topics/htmlhelp_rwbuild_hs/rwwhthow/whatare/dmobj/sq_a_lexical_references.htm
(This page is about Reports 10.1.2 but Lexical references are identical in Reports 6i and Reports 10.1.2)

[Solved] 27.8.4 How to Create a VO on a REF CURSOR - Missing first row
Searching the forum I found: BC4J - Get one less row from view object.
Dive into BC4J related --REF CURSOR (Resultset)
The first message did not have any answers, and the second had a follow up question - still no answers though - and I thought I would try a different title.
(This is off topic, but it would be a great help if the search results also displayed the number of replys in the thread. That way, I wouldn't have to view the messages that don't have responses.)
(This will be deployed on a server that has the ADF for JDeveloper 10.1.2 installed, so using that version of JDeveloper to develop the app.)
Okay, back to the problem ==>
I created a VO from a ref cursor, using the manual as a guide. When I run a page that displays a read only table of the view object, I am missing the first row. (Always the first row!) I don't have any order set, and if I call the ref cursor in a Java program for testing, I see all rows and the count is correct.
One other point, when I call the page, I get the following validation error:
Validation Error
You must correct the following error(s) before proceeding:
* JBO-29000: Unexpected exception caught: java.lang.ClassCastException, msg=null
* null
I still see the table, it is just missing the first row of data.
In my form I have first, previous set, next set , and last
navigation buttons. If I press last then first, the error goes away. I still don't see the missing row though.
Any guidance would be appreciated! I can post my code, but it is pretty much the same code in the AdvancedViewObjectExamples.zip in the ViewObjectOnRefCursor example. I just substituted my two package calls (getRefCursor and getRefCursorCount).
Thanks, KenWent back to a backup copy of the source. Fixed the error. Now I'm back to just not being able to see the first row of data.
Additional Note: I had removed fields in the display. Once I truncated the ps_txn table in the schema defined by the model, the data would display (Still without the first record.)
Are there any examples that are more in depth than the few pages in the developer guide?

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 advanceHi guys
Check out the last 2 posts in this thread for ideas on how to implement 1.

Problem in passing ref cursor values as parameter in where clau.Most Urgent
Problem:
1) I have used normal cursor (C_hubmsgid_set) with some select statement such as grouping and all.
After executing the query it will return some resultset to the specified cursor.
2) I am trying to use another cursor which is ref cursor but the problem is
I want to give all the resultset based on all the conditions to the ref cursor.
But the cursor will get only the last record due to overwriting .how to get all
the result set in a ref cursor like
cursor c1 is select .....
loop
open refcursor for
Select * from ....where condition
end loop
After this the refcursor( p_sysaudithistory_cur) which should have all the resultset matched by the where condition.
3. It should be java compatible one.
4. I am not able to match cursor row = IN Pameter value

Please solve this Refcursor issue PLEASE -
Dear All,
Version : '11.2.0.2.0'
I have a procedure which gets called from a screen ( on .Net) if use pushes a particular button.
The procedure takes 15 minutes to complete.
My requirement is to intimate the front end(.Net) as soon as the procedures gets called successfully without waiting for its completion as it is going to take 15 mins.
The reason being, the front end will popup a message saying that " The process is going to take long time, A mail will be sent to u after its completion" once it has been intimated that the procedure has been called successfully.
Could you please suggest can i return a cursor to front end without even manipulating the data.
i hope my question is understandable.9876564 wrote:

It seems to me that your problem is not an Oracle one, but a user interface one.
I'm assuming the slowness of the procedure is due to how long it's taking to query the data, and if you can't speed that up then, to have the procedure return a ref cursor, the connection between the front end and the procedure must be maintained (the process on Oracle must belong to a session, and the front end needs to be connected to that session).
So, you can't have Oracle go off and start a seperate process and then pass back the ref cursor when it's finished, because even though you can spawn off seperate processes such as using DBMS_JOB or DBMS_SCHEDULER, they will run in their own 'session' and the calling code won't keep a hold on any of those sessions... they're effectively stand-alone and seperate.
What you'll have to do is likely get your .net application to spawn off a child process to the main app, that presents the message saying it'll take some time, does the call to Oracle and waits for Oracle to return the resultant ref cursor, which it can then pass back to the main application etc. Due to .net allowing for multi-tasking, that is where the split processing should take place. -
I have a procedure Pr_job1 with select and followed by insert statements.
In pr_job1 I am using a ref cursor like open cursor for ‘statement’. This query takes a long time to execute ie more than 20 mins.
To check the dynamically framed query I gave a insert to a dummy_tab table just below the cursor
Like ..
Open p_cv for ‘select statement’;
Insert into dumm_tab (123,sysdate,’select statement’);
Commit;
Loop
Fetch p_cv into m_rec;
Exit when p_cv%notfound;
Rest of the statements.
End loop;
In this case finally it gave an error after 20 mins
Like
sqlerrm ORA-01652: unable to extend temp segment by 128 in tablespace
TEMP
ORA-02063: preceding line from CARSDBP1
I just checked the v$locked_objects before It gives the error. There I found a lock for the dummy_tab table. My question is will the query will execute for open cursor or while it executes the fetch statement. I ran the query alone in the sql plus window as a normal query. There also I got the table space error.
Thanks in advance…….

JeevaHow about you show us an exact copy / paste from SQLPLUS of what you are running? And perhaps you can clarify your question a bit. You have exceeded the allotted amount of space defined for the tablespace in which your table is located, so you should get your local DBA to allocate more space ....
Aside from that, i'm not sure what your question is about table locking, there are many types of locks, and i have no idea what you viewed that made you suspect the table was locked.... -
Spliting SDO_JOIN in two ref cursors
Hi,
What is the best/most efficient way to return two ref cursor using a SDO_JOIN?
In other words, from this example taken from the Oracle Spatial User Guide
SELECT a.gid, b.gid FROM parks a, highways b,
TABLE(SDO_JOIN('PARKS', 'SHAPE', 'HIGHWAYS', 'SHAPE',
'mask=ANYINTERACT')) c
WHERE c.rowid1 = a.rowid AND c.rowid2 = b.rowid;
I would like to have a procedure that split the result of the above Select in two ref cursors. Something like this:
PROCEDURE "GET_PARKS_HIGHWAYS"
"P_PARKS" OUT SYS_REFCURSOR,
"P_HIGHWAYS" OUT SYS_REFCURSOR
as
BEGIN
/* Here I want every Parks that interact a highway
OPEN P_PARKS FOR
SELECT * FROM PARKS WHERE ....
/* Here I want every highway that interact a park
OPEN P_HIGHWAYS FOR
SELECT * FROM HIGHWAYS WHERE ....
END
Can I do this with a single SDO_JOIN or do I have to put one in the where clause of each select?
Hope that somebody understand! If not, let me know, I will try to be clearer.
Thanks
Frederic GouletHi Frederic,
You will get the complete set of answers for both questions when using the anyinteract mask, i.e. you will have in your result set:
All of the parks that interact with highways, and all of the highways that interact with parks.
If you want, you can order by a.gid, and for each park you would see all of the highways.
If you order by b.gid, for each highway you would see all the parks.
The result set is complete in both cases.
Hope this helps. -
Open ref cursor in a procedure
Hi
I have a procedure which has 3 input parameters and 1 REF CURSOR type OUT parameter.
In the body of the procedure a select query is dynamically being created, and just before the end of the procedure the REF CURSOR is opened for SELECT(dynamic) query
For Ex: Create or replace procedure proc_name(a in number,b in number,c in number,RETVAL OUT REF CURSOR) as
decalre
strQry varchar2(3000);
begin
-- strQry is select query built dynamically
OPEN RETVAL for strQry;
end proc_name;
This procedure is being called by a java application. My question is what the open cursor statement is doing in the procedure?
Any ideas? Thanks!
greddyHi,
As i know, for example if we want to generate a report for some particular records in our project.consider we are using java as front end and oracle as backend. ok. In that case we need to bring the data from backend to front end ,for that in backend (oracle) we can write procedure to perform this task using ref cursors.
Note: ref cursor will provide the most efficient way in bringing the records from back end to front end.
Create or replace procedure proc_name(a in number,b in number,c in number,RETVAL OUT REF CURSOR) as
decalre
strQry varchar2(3000);
begin
-- strQry is select query built dynamically
--if we are using dynamic query, we can filter out the records using id or name or date
once we did, we need to pass the values to calling enviroment, since we declared the ref cursor as out parameter, we can use the ref cursor to pass the values to calling enviroment. Since we are using ref cursor we need to open the cursor for that dynamic query.
OPEN RETVAL for strQry;
end proc_name;
hope this information is some what helpful. if you got any details regarding this please post it..
thanks. -
Ref Cursors in a stored Procedure
Can some help me with an answer to the below question.
How many ref cursors can be declared in a stored procedure in oracle?
Thanksuser533016 wrote:
You are right. Keeping so many cursors open is not good at all. But i was doing this to see where it breaks and is there something that definitely controls the number of refcursors in allowed a PL/SQL block.As Karthick already mentioned you have the OPEN_CURSORS parameter which defines how many open cursors you may have in any one session.
However, this doesn't just apply to Ref Cursors. If you open explicitly defined cursors then this will also count towards that, as well as issuing select statements as they are implicit cursors... e.g.
declare
cursor c1 is
select * from emp;
cursor c2 is
select * from dept;
v_c1 c1%ROWTYPE;
v_c2 c2%ROWTYPE;
v_cnt number;
begin
open c1; -- now we have 1 open cursors
loop
fetch c1 into v_c1;
exit when c1%notfound;
open c2; -- now we have 2 open cursors
loop
fetch c2 into v_c2;
exit when c2%notfound;
select count(*) -- this counts as opening cursor number 3.
into v_cnt
from payroll;
-- after the select statement the implicit cursor is automatically closed, so now we have 2 open again
end loop;
close c2; -- after this we just have 1 more open
end loop;
close c1; -- after this we have no open cursors
end; -
Using Ref Cursors as region source
Is it possible to use a function that returns a ref cursor as a region's source? I asked this question at the end of another thread and got no response so I made this new thread.
I created an application called 'ref cursor' on apex.oracle.com at
http://apex.oracle.com/pls/otn/f?p=4550
Workspace : wc_jason
username: dev
password: password
There is a table named TBL and a function returning a ref cursor name FNC. On the home page there are three regions, one using a sql statement, one using a pl/sql function returning a sql statement, and one that attempts to use a ref cursor. The ref cursor region's condition is set to NEVER because I couldn't get it to work and I wanted to show the page with the two working regions.
Can I even use a ref cursor in this manor?
Thanks for the help.Heres a quick example I did for you:
create or replace package pkg_refcursordemo
as
type rc_generic is ref cursor;
rec_emp emp%rowtype;
type tab_emp is table of emp%rowtype;
procedure proc_get_emp (
pi_ename in emp.ename%type
,pio_emp_rc in out rc_generic
function func_get_emp (
pi_ename in emp.ename%type
return tab_emp pipelined;
end pkg_refcursordemo;
create or replace package body pkg_refcursordemo
as
-- Procedure with in out ref cursor parameter
procedure proc_get_emp (
pi_ename in emp.ename%type
,pio_emp_rc in out rc_generic

begin
open pio_emp_rc for

where ename like pi_ename||'%';
end proc_get_emp;
-- Wrapper pipelined function
function func_get_emp (
pi_ename in emp.ename%type
return tab_emp pipelined
is
l_rc_generic rc_generic;
l_rec_emp emp%rowtype;
begin
proc_get_emp (
pi_ename => pi_ename
,pio_emp_rc => l_rc_generic
loop
fetch l_rc_generic into l_rec_emp;
exit when l_rc_generic%notfound;
pipe row ( l_rec_emp );
end loop;
close l_rc_generic;
return;
end func_get_emp;
end pkg_refcursordemo;
create or replace view vw_emp

Whats cool is you can declare the view with an APEX variable in it e.g.
create or replace view vw_emp
as
select empno
, ename
, job
, mgr
, hiredate
, sal
, comm
, deptno
from table ( pkg_refcursordemo.func_get_emp( v('P1_ENAME_PARAM' ) )

I was looking at this example given for ref cursor
CREATE TABLE employees (
empid NUMBER(5),
empname VARCHAR2(30));
INSERT INTO employees (empid, empname) VALUES (1, 'Dan Morgan');
INSERT INTO employees (empid, empname) VALUES (2, 'Hans Forbrich');
INSERT INTO employees (empid, empname) VALUES (3, 'Caleb Small');
COMMIT;
CREATE OR REPLACE PROCEDURE pass_ref_cur(p_cursor SYS_REFCURSOR) IS
TYPE array_t IS TABLE OF VARCHAR2(4000)
INDEX BY BINARY_INTEGER;
rec_array array_t;
BEGIN
FETCH p_cursor BULK COLLECT INTO rec_array;
FOR i IN rec_array.FIRST .. rec_array.LAST
LOOP
dbms_output.put_line(rec_array(i));
END LOOP;
END pass_ref_cur;
set serveroutput on
DECLARE
rec_array SYS_REFCURSOR;
BEGIN
OPEN rec_array FOR
'SELECT empname FROM employees';
pass_ref_cur(rec_array);
CLOSE rec_array;
END;
In this P_cursor is weaklytyped ref cursor. My question is
1. How does the fetch identifies which columns are there in the cursor ?
2. If I add another column (say empid) to cursor query it is throwing error message !
3. In my case; I need to use the cursor columns for futher processing in my proc. In such cases how do we define the cursor ?
TIA1. How does the fetch identifies which columns are there in the cursor ?It doesn't. It just puts the first value into the first variable, the second into the next and so on. If it doesn't fit you get an exception (as you found).
In fact a strongly typed ref cursor is the same underneath, it just makes your code declare things slightly more specifically.
2. If I add another column (say empid) to cursor query it is throwing error message !You would have to modify the target variable and the fetch to match the cursor.
3. In my case; I need to use the cursor columns for futher processing in my proc. In such cases how do we define the cursor ?You have to know what columns you are fetching so that you can do something with them. Even if you parsed it out (as SQL*Plus does when it prints a refcursor variable for example) the rest of your code would need to know what it was referring to, how many columns, their datatypes etc.
