Function returning cursor..

i have written a function which returns me a cursor ...
CREATE OR REPLACE function getAdvisorInfo(advID IN char)
RETURN types.ref_cursor
AS
atp_cursor types.ref_cursor;
BEGIN
OPEN atp_cursor FOR
select ad.Advisor_id, ad.Bundle_code, bd.bundle_name, ad.platform,ad.position_code,ad.advisor_first_name,ad.advisor_last_name,ad.date_bundle_changed,ad.status from advisor_details ad,bundle_details bd where ad.bundle_code = bd.bundle_code and ad.advisor_id=advID;
return atp_cursor;
end getAdvisorInfo;it reads 2 tables as of now...
1. advisor_details and values it reads from this table are ...
a. advisor_id,
b. bundle_code,
c. platofmr,
d. position_code,
e. advisor_first_name,
f. advisor_last_name,
g. date_bundle_changed,
h. status
2. bundle_details ...and values it readds from this table are ...
a. bundle_name.
it works absolutely fine...
now the value date_bundle_changed from advisor_details has to be read from a third table ...and to read that value i need a select query which is like ...
SQL> select max(date_timestamp-0) from advisor_details_history where advisor_id=advID and date_timestamp between systimestamp-30 and systimestamp and change_reason='Bundle Selection';
so in the query "select ad.Advisor_id, ad.Bundle_code, bd.bundle_name, ad.platform,ad.position_code,ad.advisor_first_name,ad.advisor_last_name,ad.date_bundle_changed,ad.status from advisor_details ad,bundle_details bd where ad.bundle_code = bd.bundle_code and ad.advisor_id=advID;" i need to replace that ad.date_bundle_changed with the above query ....which reads date_timestamp from a third table and then sets the value in this query itself...
can some1 tell me how can i do this...or i need to use union only....:(
is there any other way then union...
please let me know..
thank you..
regards,
chintan..
let me know if i am not soo clear in conveying my problem...

can some1 give me hint on how to do this..
even with union i m struggling a bit... :(
here is my function with union....but facing problems to form the query...

Custom report based on function returning cursor

Hi,
I'm trying to create a generic function that will be the basis of a custom report in Grid Control.
The idea is to pass in a database link name, then the function builds a cursor to select using that name, and returns the result to Grid control to render.
At the moment all I get is an empty table.
My function is defined as follows:
create or replace function list_databases(p_dblink varchar2) return sys_refcursor
is
db_name varchar2(40);
c_cursor sys_refcursor;
v_query varchar2(100);
begin
v_query := 'select name from rc_database@'||p_dblink;
open c_cursor for v_query;
return c_cursor;
end;
The custom report contains a 'Table from SQL' type, with the following sql statement:
select sysman.list_databases('rmancat_test') from dual
I've tried playing around with the ??EMIP_BIND_RESULTS_CURSOR?? bind variable but it only seems to work if I write the pl/sql block in the custom report, rather than going for a generic function.
Any ideas are most welcome.
Chris

Why not use a simple procedure to achieve the same thing?

Function returning cursor to be used in select statement

I have written a function which returns a cursor. I want to use this in a select statement to display rows. How to do this.
Eg : function - test_fn return sys_refcursor. (returns empno, empname, deptname)
select test_fn from dual
This should return
empno empname deptno
1 name1 dept1
2 name 2 dept2
....

Try This::
SCOTT@xe_144>variable c refcursor

Returning Cursor from Function

I have been struggling all afternoon to get a package function
to return a cursor. Following some advice from the forums, I
think I'm getting close. <vbg> But am getting a compile error
on my RETURN statement. Can someone please help or post a
working example of how to do this. Thanks!
-- IN PACKAGE HEADER
type package_cursor is ref cursor;
function testfunction (p_system_date in date)
return package_cursor;
-- IN PACKAGE BODY
function testfunction (p_system_date in date)
return package_cursor is
cursor c1 is
select columns from tables where mydate = p_system_date;
begin
open c1;
return c1;
end testfunction;

Nevermind, I figured it out by using Barbara Boehmer example in
the "function returning record or table" thread.
function testfunction (
p_system_date in date)
return package_cursor is
vret package_cursor;
begin
open vret for
select columns from tables where mydate = p_system_date;
return vret;
end testfunction;

How to get a stored function return value (which is not a cursor)?

I want to do so with ADO inside Visual Basic. I know how to call a stored procedure, but nothing I tried could help me in calling a stored function and getting its return code. Note that the function has no cursors within its argument or return code.
Your quick response would be appreciated
Eyal

Eyal,
A stored function returns a value. You need to have the first parameter (of correct data type) for the returned value. The parameter binding is pretty much the same as you would do with stored procedures.
e.g. "begin :1= proc(....); end;"

Function returning error - change notification

I have a function returning error text. When error occurs I get the message
'xx error has occurred' on the screen (in notification). Is there a way to control the message text so I can display different text?

It's something like this:
DECLARE l_code zip.code%TYPE;
got_error varchar2(1) := 'N';
l_check_fld varchar2(30000);
l_error_fld varchar2(32000);
vErrorFields varchar2(1000);
CURSOR check_zip IS
select ''
from zip
where code = l_code;
BEGIN
apex_collection.create_or_truncate_collection('ZIP');
FOR i IN 1 .. apex_application.g_f03.COUNT LOOP
vErrorFields := '';
/* Code MUST be entered */
if (apex_application.g_f03(i) is null and
(apex_application.g_f04(i) is not null or
apex_application.g_f05(i) is not null))then
got_error := 'Y';
vErrorFields := vErrorFields || ',f03';

Can Function Return more than One Values ??

Hi Experts,
I would like to ask you Can Function Return more than one values. I Used Function with Out and In out parameter and its working Fine..
1. what is harm using Out and In out parameter in function
2. if we can use Out and In out parameter in Function so what is deffernce between procedure and Function.
3. Is there any Other Way Though which we can return more the One values in Function.
Please advice me...
Thanks
Umesh Goel

Yes/No.
You can return multiple value from function. But, in PL/SQL and not in a SQL.

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

Email me diorectly and I will get you some code that might help. I fail to see the relevance of posting this type of information in the JDeveloper forum.

How to migrate sql server 2000 user defined function returns table

Hi,
How do I capture the SQL Server 200 user defined function that returns table? Is this supported in the current version of Oracle Migration Workbench? I am using the latest version - Release 9.2.0.1.0 with SQL SERVER 2000 plug-in.
I was able to capture the SQL Server 2000 user defined function that returns string and smalldatetime but not the functions return table during the migrate data source stage.
Thanks in Advance,
Susan

Susan,
This is not currently supported. The next release of the Oracle Migration Workbench (due very soon), will do a better job of catching this mad reporting an error. We are looking into a suitable mapping and have created bug # 2355073 - TABLE DEFINITIONS NOT ACCEPTED FOR TABLE FUNCTIONS to track this issue.
Once possible solution we are looking into is using the object type to emulate. Here is an example from the bug:
Original table

StoredFunctionCall fun = new StoredFunctionCall();
fun.setProcedureName("getEmpArray".toUpperCase());
Object[] arr = new Object[]{"aa", "fgfg", "bbb"};
ArrayDescriptor arrDescriptor =
ArrayDescriptor.createDescriptor("string_table".toUpperCase(),
connection);
ARRAY arrayToPass = new ARRAY(arrDescriptor, connection, arr);
fun.addUnamedArgumentValue("a");
fun.addUnamedArgumentValue("b");
fun.addUnamedArgumentValue(arrayToPass);
fun.setResult("FUNCTION_RESULT"); // for get result by this name
Vector<DatabaseRecord> list = session.executeSelectingCall(fun);
But Exception
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Error Code: 6550
Call: BEGIN ? := GETEMPARRAY(?, ?, ?); END;
bind => [=> FUNCTION_RESULT, a, b, oracle.sql.ARRAY@21fbc01]
Please help me

A few issues,
1 - JDBC does not support the PLSQL TABLE type, you must use a VARRAY type, or wrap the TABLE function call in a function that takes a VARRAY.
TopLink also has support for PLSQL types in its PLSQLStoredProcedureCall class, but no support is currently offered for StoredFunctions.
You can't pass the VARRAY type for the TABLE argument.
2 - Your function returns a VARRAY, so you need to define this type in the StoredFunctionCall result.
We don't currently expose the API to set a Array type for the result, so you would need to access the call's first parameter directly, or use a StoredProcedureCall (and convert your function to a procedure).
You may also wish to investigate returning a cursor from a stored procedure instead of the varray.
You could also access the JDBC connection directly and perform the call using JDBC code.
Feel free to log these issues in EclipseLink.

Function return single record

create or replace function etest
(dep in number)
return varchar2
is
dept number:= 0;
cursor c1 is
select deptno
into dept
from emp
where deptno = dep;
begin
open c1;
loop
fetch c1 into dept;

7782 CLARK 2450
7739 KING 5000
7934 MILLER 13000
Thanks to all

You could use a REF CURSOR:
PL/SQL 101 : Understanding Ref Cursors
http://www.oracle-base.com/articles/misc/UsingRefCursorsToReturnRecordsets.php
or maybe a pipelined function....

http://www.oracle-base.com/articles/9i/PipelinedTableFunctions9i.php
depending on what client is fetching.

Function Returning Object

Function Returning Object
Hi Experts,
Here is my code,
-- DROP TYPE TYP_EMP;
-- DROP TYPE TYP_EMP_OBJ;
CREATE OR REPLACE TYPE TYP_EMP_OBJ AS OBJECT
 TOTAL NUMBER,
 ROWINDEX NUMBER,
 EMPNO NUMBER,
 ENAME VARCHAR2(50),
 LOC VARCHAR2(100)
CREATE OR REPLACE TYPE TYP_EMP AS TABLE OF TYP_EMP_OBJ;
CREATE OR REPLACE FUNCTION FUN_GETEMP_LOCATION(pmDeptno IN NUMBER) RETURN VARCHAR2
AS
 vLocation DEPT.LOC%TYPE;
BEGIN
 SELECT LOC INTO vLocation FROM DEPT WHERE DEPTNO=pmDeptno;
 RETURN vLocation;
END;
CREATE OR REPLACE FUNCTION FUN_GET_EMP_DETAILS
 pmType IN NUMBER,
 pmStartPage IN NUMBER,
 pmEndPage IN NUMBER,
 pmOrderBy IN VARCHAR2
RETURN TYP_EMP PIPELINED
AS
 vString VARCHAR2(100);
 TYPE vRefCursor IS REF CURSOR;
 Cur vRefCursor;
 Rec TYP_EMP_OBJ := TYP_EMP_OBJ(NULL,NULL,NULL,NULL,NULL);
BEGIN
 IF pmType IS NULL THEN
 SELECT 0,NULL,NULL,NULL,NULL INTO Rec.TOTAL,Rec.ROWINDEX,Rec.EMPNO,Rec.ENAME,Rec.LOC FROM DUAL;
 RETURN;
 END IF;
 IF pmType =1 THEN
 OPEN Cur FOR

 PIPE ROW(Rec);
END LOOP;
CLOSE Cur;
RETURN;
END;
SELECT * FROM TABLE(FUN_GET_EMP_DETAILS(NULL,1,10,'ORDER BY EMPNO DESC'));
SELECT * FROM TABLE(FUN_GET_EMP_DETAILS(1,1,10,'ORDER BY EMPNO DESC'));
SELECT * FROM TABLE(FUN_GET_EMP_DETAILS(2,1,10,'ORDER BY EMPNO DESC'));
Executing First Query
Actually Whats happening on Executing first Query, it does not return as specified
SELECT 0,NULL,NULL,NULL,NULL INTO Rec.TOTAL,Rec.ROWINDEX,Rec.EMPNO,Rec.ENAME,Rec.LOC FROM DUAL;
It just returning null;
Executing Second Query
It return correctly.
Executing Third Query
It return correctly.
Can anyone suggest how to work out like this?
Thanks,
Dharan V

You dint pipe the row if pmType is NULL
CREATE OR REPLACE FUNCTION FUN_GET_EMP_DETAILS
 pmType IN NUMBER,
 pmStartPage IN NUMBER,
 pmEndPage IN NUMBER,
 pmOrderBy IN VARCHAR2
RETURN TYP_EMP PIPELINED
AS
 vString VARCHAR2(100);
 TYPE vRefCursor IS REF CURSOR;
 Cur vRefCursor;
 Rec TYP_EMP_OBJ := TYP_EMP_OBJ(NULL,NULL,NULL,NULL,NULL);
BEGIN
 IF pmType IS NULL THEN
 SELECT 0,NULL,NULL,NULL,NULL INTO Rec.TOTAL,Rec.ROWINDEX,Rec.EMPNO,Rec.ENAME,Rec.LOC FROM DUAL;
 pipe row(rec); ----------------<<<<----------------- This is required
 RETURN;
 END IF;
 IF pmType =1 THEN
 OPEN Cur FOR
 'SELECT * FROM(
 SELECT
 COUNT(*) OVER(),
 ROW_NUMBER() OVER('||pmOrderBy||') ROW_INDEX,
 EMPNO,
 ENAME,
 FUN_GETEMP_LOCATION(EMP.DEPTNO) LOC
 FROM EMP)T
 WHERE T.ROW_INDEX BETWEEN '||pmStartPage||' AND '||pmEndPage;
 ELSE
 OPEN Cur FOR
 'SELECT * FROM(
 SELECT
 COUNT(*) OVER(),
 ROW_NUMBER() OVER('||pmOrderBy||') ROW_INDEX,
 2,
 ENAME,
 FUN_GETEMP_LOCATION(EMP.DEPTNO) LOC
 FROM EMP)T
 WHERE T.ROW_INDEX BETWEEN '||pmStartPage||' AND '||pmEndPage;
 END IF;
LOOP
 FETCH Cur INTO Rec.TOTAL,Rec.ROWINDEX,Rec.EMPNO,Rec.ENAME,Rec.LOC;
 EXIT WHEN Cur%NOTFOUND;
 PIPE ROW(Rec);
END LOOP;
CLOSE Cur;
RETURN;
END;Edited by: Karthick_Arp on Dec 24, 2009 2:12 AM
