Function call returned in ref cursor

We have a ref cursor that calls a function in a package. When ODP.NET reads the cursor, it can't see what the function is returning. OO4O works fine, and if I take the sql that populates the ref cursor and put it into a temporary table, then select from that temporary table to return the ref cursor to ODP, it works fine. Anyone else seen this issue? Any help would be appreciated. Thanks.

Did you set the parameter direction to be ParameterDirection.Input when you created the parameter? Post your code.

Plsql use a function which returns a ref cursor

Hi
I've been using an function which returns a ref cursor. I've been returning this into a java resultset. Fine!
Now i'm in plsql and want to use the same function. I'm not sure how to get this resultset in plsql.

It's not very practical to use a refcursor like you want to, but here you go
create or replace function test_ref
return sys_refcursor
is
v_rc sys_refcursor;
begin
open v_rc for select emp_name from emp ;
return v_rc;
end;
declare
v_rc sys_refcursor;
v_emp_name emp.emp_name%type;
begin
v_rc := test_ref ;
loop
    fetch v_rc into v_emp_name ;
    exit when v_rc%notfound ;
    dbms_output.put_line('Employee Name: '||v_emp_name );
end loop;
end;

Oracle Function returns a Ref Cursor to a ResultSet object - Performance

My program calls an Oracle PL/SQL function which returns a ref cursor to a ResultSet object. I know that the function runs to completion relatively quickly when i run it in an anonymous block but when the call is made through my Java application the resultset takes about 30 mins to return. Below is a snippet of my code:
currentConnection = ConnectionManager.getInstance().getConnection();
reportStmt = currentConnection.prepareCall("BEGIN ? := ENVISION.PKG_WMS_TO_AP.F_REPORT_CI_SC_HOLDING(?,?); END;"); reportStmt.registerOutParameter(1, OracleTypes.CURSOR);
reportStmt.setString(2, invoice.getCrewHQ());
reportStmt.setDate(3, invoice.getWrCompletionDate());
reportStmt.execute();
reportRS = ((OracleCallableStatement) reportStmt).getCursor(1);
Through a debugger I see that the second last statement (reportStmt.execute()) runs quickly. It is only when I step into the last statement that the debugger takes up to 30 minutes.
Any thoughts?

How to include an out param of a stored proc called inside a ref cursor...????

I have a stored proc that is defined as
CREATE or REPLACE
PROCEDURE ABC
(linkid IN CHAR,
Year_in IN DATE,
Method_in IN CHAR,
Date_out OUT DATE,
average_out OUT NUMBER)
is
begin
end;
another partially completed stored proc that returns a ref
cursor defined as follows:
create or replace package zzz
as
type cursorType is ref cursor;
end;
create or replace function test return zzz.cursortype
as
date_OUT date;
Average_OUT number;
l_cursor zzz.cursorType;
CURSOR temp_cur is
SELECT l.linkid, L.routenumber, ABC(l.linkid,
to_date('01/01/2000', 'mm/dd/yyyy'),
'2',
date_OUT,
average_OUT)
FROM LINK l
WHERE l.LINKID <= '010999';
begin
open temp_cur;
end;
inside test (which I need help completing), how can I refer to
the date_out and the average_out params returned by ABC() so
that these values are in turn passed to the cursortype defined
in package zzz?
Thanks in advance.

Try rewriting your abc proceudre as two functions, abc1 and
abc2, and rewriting your test function as a test procedure. See
if you can fill in the blanks prefaced by hyphens -- in the
following code:
CREATE OR REPLACE FUNCTION abc1
(linkid      IN CHAR,
   year_in     IN DATE,
   method_in   IN CHAR)
RETURN DATE
IS
date_out DATE;
BEGIN
SELECT   --
INTO     date_out
FROM     --
WHERE    --;
--or
date_out := --;
RETURN date_out;
END abc1;
CREATE OR REPLACE FUNCTION abc2
(linkid      IN CHAR,
   year_in     IN DATE,
   method_in   IN CHAR)
RETURN NUMBER
IS
average_out NUMBER;
BEGIN
SELECT   AVG (--)
INTO     average_out
FROM     --
WHERE    --
GROUP BY --;
--or
average_out := --;
RETURN average_out;
END abc2;
CREATE OR REPLACE PACKAGE zzz
AS
TYPE cursortype IS REF CURSOR;
PROCEDURE test
    (temp_cur OUT cursortype);
END zzz;
CREATE OR REPLACE PACKAGE BODY zzz
AS
PROCEDURE test
    (temp_cur OUT cursortype)
IS
BEGIN
    OPEN temp_cur
    FOR
    SELECT l.linkid,
           l.routenumber,
           abc1 (l.linkid,
                TO_DATE ('01/01/2000', 'mm/dd/yyyy'),
                '2'),
           abc2 (l.linkid,
                TO_DATE ('01/01/2000', 'mm/dd/yyyy'),

Procedure to RETURN a REF CURSOR

Environment:
OWB10g Client on Windows XP Professional
Repository - 9.2.0.4 on UNIX (AIX 5.2)
Target - 9.2.0.4 on UNIX (AIX 5.2)
Is it possible to create a PROCEDURE in OWB that returns a REF CURSOR?
It was not one of the TYPEs available when specifying the procedure parameters.
Is this an enhancement that's coming if it's not possible today?
Many thanks for all feedback. This is a great interactive discussion forum.
Gary

Good afternoon Gary,
Have you checked whether it's possible to use the table-function?
Don't know you specific requirements, but according to the explanation ("Table functions extend PL/SQL and are a new option in Oracle9i. This option allows a function to accept, process and return multiple rows.") it at least is capable of returning rowtypes.
Cheers, Patrick

UDPWrite in a loop. "A Windows Sockets function call returned an unexpected error."

Hello together,
i use UDP Support Library in NI CVI 9.0. When i wait for receiving a packet at the pc to send then a packet from the pc, the functions UDPRead and UDPWrite work fine. If i want to test the maximum throughput, i put the UDPWrite in a loop, but then an error occurs. It is "kUDP_UnexpectedWinsockError"
Error Popup:
"NON-FATAL RUN-TIME ERROR:   "main.c", line 53, col 22, thread id
0x00000C18:   Library function error (return value == -6822
[0xffffe55a]). A Windows Sockets function call returned an unexpected
error."
Line 53:
status = UDPWrite (channel, 60100, "192.168.1.10", pOutputBuffer, 1458);
the whole loop:
while(1)
status = UDPWrite (channel, 60100, "192.168.1.10", pOutputBuffer, 1458);
counter++;
if(counter>50)
break;
else{;}
The error occurs after 3-16 packets have been sent. If i step through the programm, no error occurs. So i guess its because the UDPWrite command is invoked too fast. pOutputBuffer has static data. I could use a delay in the loop, but then i dont know how to configure for maximal throughput.
Any ideas how to avoid this error?
Regards Florian

Hello and thank you for your answer. Sorry that i reply a month later.
I dont know what you mean by "let 'er rip approach". Do you mean something like:
status = UDPWrite (channel, 60100, "192.168.1.10", pOutputBuffer, 1458);
if(status==0)
counter++;
else
Delay(0.00005);
I did not yet try to put the packet number in the payload, but there is just a 30 cm crossover cable between the two devices, no switch, no router. So the sequence should not be interruptet. And even if they arrive in chaos, i dont mind.
I have contacted the NI support 2 weeks ago, but no response yet.
I did some tests with a delay between the execution of UDPWrite(). The code:
float time = 0.0;
for(i = 1; i < 1000; i++)
  status = UDPWrite (channel, 60100, "192.168.1.10", pOutputBuffer, 1458);
  time = 1.0 / i;
  Delay(time);
The results:
For i between 1 and 1000: no error, the speed of the last ten packets was about 6.5 MBit/s
For i between 1000 and 2000: error occured at i = 1585 (variable time in Delay was 0.0006313), the speed of the last ten packets was about 8 MBit/s
Then i put some constant values in Delay and ran 100 UDPWrite iterations:
Delay(0.0006): 7.48 MBit/s
Delay(0.0001): 10.7 MBit/s
Delay(0.00001): error occured at i=31, speed of 31 packets was 12.0 MBit/s
Delay(0.00008): 100 of 100 packets, speed 10.9 MBit/s
Delay(0.00005): error at i=41, speed of 41 packets 11.1 MBit/s

How to return a ref cursor from this dbms_sql?

Hi,
Can anyone show me how to return a ref cursor from this dbms_sql based procedure? I see 11g has a dbms_sql.to_refcursor(cursor_handle). How can this be done is 10g?
Thx.
CREATE OR REPLACE PROCEDURE Sample_Get_t
p_sample_id sample.sample_id%TYPE,
p_contract_id sample.contr_id%TYPE
IS
cursor_handle INT;
sql_stmnt varchar2(500);
rows_processed NUMBER;
BEGIN
sql_stmnt :=
'SELECT
sample_id,
contr_id,
rcpt_id
FROM
sample s
WHERE
s.contr_id = :1
and s.sample_id = :2
ORDER BY
sample_id';
cursor_handle := dbms_sql.open_cursor;
dbms_sql.parse(cursor_handle, sql_stmnt, dbms_sql.native);
dbms_sql.bind_variable(cursor_handle, ':1', p_contract_id);
dbms_sql.bind_variable(cursor_handle, ':2', p_sample_id);
rows_processed := dbms_sql.execute(cursor_handle);
dbms_sql.close_cursor(cursor_handle);
END Sample_Get_t;

In 10 this cannot be done with dbms_sql (to my knowledge). There are a couple of other options.
1) open the ref cursor for the dynamic statement using bind variables (or SYS_CONTEXT variables, which i prefer since they are much easier to deal with when you are dynamically adding predicates).
declare
   wRefCursor SYS_REFCURSOR;
begin
   open wRefCursor for 'select * from all_objects where owner = :Logged_in_user' using user;
end;
/or using the context (the context will bind for you)
declare
   wRefCursor SYS_REFCURSOR;
begin
   open wRefCursor for 'select * from all_objects where owner = SYS_CONTEXT(''CONTEXT_NAME'', ''VARIABLE_NAME'') ';
end;
/Be aware that contexts ALWAYS return varchar values, so if you are comparing to a number you should wrap it in TO_NUMBER, a date, TO_DATE and so on....
2) change the DBMS_SQL to do an insert into a global temporary table and return the ref cursor which select's * from GTT;
3) upgrade to Oracle 11 :)

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.

Parallel piplelined function not parallelizing with ref cursor

RDBMS 11.2.0.3
I have a function with the following signature

f.out_213     280399
f.out_230     286834

    dbms_output.put_line(rec.file_name || chr(9) || rec.num_records );
end loop;
end;
f.out_914     1133016Is this an expected behavior or am I doing something wrong? How can I use the function when the client returns the SQL statement as a character string

Returning a Ref cursor as an OUT Parameter

Hi Guys
I have defined 2 Types and 2 Ref cursors as shown below.I have written a procedure having 2 IN and 2 OUT parameters which are of type Ref cursors and return records to the calling client.

Ref cursor to object and return to ref cursor

how i will call object type from refcursor and return value to ref cursor .

I need a help. please help me.
takes oracle object types as input/output.
PROCEDURE createserviceorder(
P_serviceorder IN serviceorder,
P_serviceid in out p_sm_type.serviceid,
P_serviceorderid out p_sm_type.serviceorderid,
Returnstatus out callstatus);
The serviceorder, callstatus are oracle object types.
The wrapper procedure for this API would be something like the example with pseudo code below
PROCEDURE createserviceorderwrapper(
P_serviceorder IN REFCURSOR,
P_serviceid in out p_sm_type.serviceid,
P_serviceorderid out p_sm_type.serviceorderid,
Returnstatus out REFCURSOR)
Map from ref cursor P_serviceorder to oracle object for serviceorder;
Map from other data types to local variables;
Call createserviceorder (pass the parameters here and get output.);
Map output callstatus to its equivalent REF CURSOR variable;
Return callstatus (and other out parameters if any )as REF CURSORS;
}

Dynamic call for a ref cursor: ORA-21779

Hi,
Here is an environment:
create or replace
PACKAGE PKG_GETDATA AS
TYPE cursor_type IS REF CURSOR;
Procedure SimpleGet (cData In Out Cursor_type);
Procedure DynamicGet (cData In Out Cursor_type);
END PKG_GETDATA;
create or replace
PACKAGE BODY "PKG_GETDATA" AS
Procedure SimpleGet (cData In Out Cursor_type) As
Begin
Open cData For
Select 1 from Dual;
End SimpleGet;
Procedure DynamicGet (cData In Out Cursor_type) As
Begin
Execute Immediate 'Begin PKG_GETDATA.SIMPLEGET(:1); End;'
Using In Out cData;
End DynamicGet;
END PKG_GETDATA;
So- first simple get works fine:
Declare
cData PKG_GETDATA.Cursor_type;
aNumber Number;
Begin
PKG_GETDATA.SimpleGet (cData);
LOOP
FETCH cData INTO aNumber;
EXIT WHEN cData%ROWCOUNT > 5 OR cData%NOTFOUND;
dbms_output.put_line (aNumber);
END LOOP;
close cData;
End;
BUT dynamic call does not works at all!:
Declare
cData PKG_GETDATA.Cursor_type;
aNumber Number;
Begin
PKG_GETDATA.DynamicGet (cData);
LOOP
FETCH cData INTO aNumber;
EXIT WHEN cData%ROWCOUNT > 5 OR cData%NOTFOUND;
dbms_output.put_line (aNumber);
END LOOP;
close cData;
End;
It throws ORA-21779 exception; what is more- it does work on 10.2 db version but does not work on 11.2 version! Could anyone explain that?

Function Call returning old SQL Query

Hello All,
I have a Pipeline Function which creates a SQL within (Dynamic SQL that gets stored in a LONG variable) based on the parameter STRING passed to the function. Inside this function, once the SQL is built, I am inserting this SQL into a log table, for logging purpose.
Note: my function has only one parameter which is a string. This string accepts a name:value pairs with a delimiter which I breakdown inside the function. But this functionality is working fine.
Issue:
When I run the function with parameter with a STRING say (Age = 20, Gender = M) for the first time, it works.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:M'));
</code>
When I change the parameters to (Age = 20, Gender = F), it gives me the results of the earlier function call.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:F'));

When I open the logs, I see the SQL being built is the earlier one.
As a test I closed the session and ran (Age = 20, Gender = F) first. It works fine. When I run a different parameter string, it always mimics the earlier function call.
Is CACHING in play here. I tried both the following:
<code> dbms_result_cache.bypass(FALSE);
dbms_result_cache.flush;
</code>
I tried multiple tests, with different parameters and only the first one runs fine and second one copied the earlier. However, when I open two sessions on two different windows it doesn't happen.
Also, in the Logging table I am capturing the input string as a confirmation, which is coming correctly. But the SQL being build mimics the earlier call.
I tried to set the variable which hold the SQL Statement to empty (v_sql := '';) at the beginning and also at the end. Still no use.
Kindly help if I am over looking anything.

I have a Pipeline Function which creates a SQL within (Dynamic SQL that gets stored in a LONG variable) based on the parameter STRING passed to the function. The LONG data type has been replaced by the LOB data type. Oracle specifically recommends not using the old LONG data type.
Issue:
When I run the function with parameter with a STRING say (Age = 20, Gender = M) for the first time, it works.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:M'));
</code>
When I change the parameters to (Age = 20, Gender = F), it gives me the results of the earlier function call.
<code>SELECT * FROM TABLE (
PIPE_FUN_SEARCH_PKG.get_search_records ('EMP_AGE:20|EMP_GENDER:F'));
</code>The tag is ** - not *<code>*.
Why a pipeline function? Why dynamic SQL? Are you using +DBMS_SQL+ to create the dynamic cursor? If not, why not? Only +DBMS_SQL+ allows dynamic binding in PL/SQL. Without that, your code will burn a lot of additional CPU on hard parsing and trash and fragment Shared Pool memory.
When I open the logs, I see the SQL being built is the earlier one.
How do you record the current SQL? Are you using a static variable to capture the SQL statement generated?
From what you have described - this is yet another horribly flawed approach in all respects. To data modelling. To relational databases. To Oracle. To SQL.
Reinventing the SQL language for data retrieval as a pipeline function using a funky parameter interface - sorry, I just don't get that. It is an insane approach.
