Opening cursor on pipelined functions

Hi forum,
Is it possible to open a cursor /any iteration of rows possible in pipelined functions ?
Pls see the example below :
cursor c is select * from TABLE ( generate_pipelined_rows())
and iterate through cusror variable of C?
Thaks,
Aneesh

may be something like this
FOR c IN (SELECT * from TABLE(generate_pipelined_rows()))
Loop
--process data
END LOOP;

Open Cursor using other function/procedure

Hi
I have a procedure that return a cursor to Java, but if it send a parameter or other I wanted to call a procedure or function and return cursor to java , Is possible it ?
Example
PROCEDURE XYZ ( P_ORD    IN NUMBER,
                 p_CURSOR OUT SYS_REFCURSOR)
IS
BEGIN
   IF P_ORD =1 THEN
      -- here I want to open cursor from other procedure/function
      OPEN P_CURSOR
   ELSIF P_ORD = 2 THEN
   END IF;
END XYZ;Message was edited by:

Looking at your example code, you say you want to open a cursor from another procedure.
I would suggest taking a step back and looking into the basics of procedural programming, especially in the area of variable scopes.
The scope of the cursor declared in another procedure will be that it exists within that procedure only.
In order to use another procedure's cursor you would have to call that procedure and have it return a SYS_REFCURSOR to your first procedure in the same manner you are trying to return a sys_refcursor to your Java code.

Use PipeLine function as datasource

Hi all.
Does anybody use PipeLine function as datasource for Bi EE ? Do you have any experience ?

For more discuss :
I was read article from Venkatakrishnan
http://oraclebizint.wordpress.com/2007/09/21/oracle-bi-ee-101323-ref-cursors-and-pipelined-functions/
and in that case all lok's fine and work. But in my case I was neded disable aggregate and order by functionality , becouse have some Issues. can anybody comment this situation :What's wrong in using PipeLine and BIee ?

Metrics " Current Open Cursors Count "

Hi,
I get an Alert message Metrics " Current Open Cursors Count is at 1201 '" on 10g database version 10.2.0.1.0 . Can anyone help me to solve this.
Thanks
Sree

Sree,
The Metric corresponds to the number of records in V$OPEN_CURSOR internal view.
The number of open cursors is a function of the number of concurrent users and the application code ,so 1201 may not necessaryly indicate a problem – it could be that you system is genuinely very busy.
You should start worrying if the number of open cursors consistently grows over time (while the workload is steady). In this case you may have a “cursor leak” – a piece of code that opens a cursor, but does not close it.
You can check that with
select substr(sql_text,1,30) , count(*) cnt
from v$open_cursor
group by substr(sql_text,1,30)
order by 2 desc
If the current open cursor are getting close to the max allowed(OPEN_CURSOR parameter), you may reset them using share pool flush (note that the shared pool flush may have some small performance impact on the system).
Hope that helps,

XSL Database Functions throwing "ORA-01000: maximum open cursors exceeded"

In my BPEL process, I have a large dataset requiring enrichment of the data by looking up values in a database. I'm doing this in an XSL transformation using either; orcl:lookup-table() or orcl:query-database() functions. This works ok for a number of records, but then fails with "ORA-01000: maximum open cursors exceeded".
This implies that these functions are not closing down open cursors after use. Is this a bug, or can I configure the data-sources to handle this?
Thanks.

I don't see any settings to fix this on the data-source itself.

Question about cursors in a function and how to return the results

Hi all,
Some tech info:
I'm using Oracle 11G database and APEX 4.0.2.00.06
I use three cursors in a function. My function is called in an APEX standard report, like this by example:
SELECT fnc_exp(tab.arg1, tab,arg2) FROM table_exp tab;
My question is: how can I return the values calculated from my function to a standard APEX report? Before, this function was used like this by Oracle Forms to fetch the cursors in the right table columns:
open c_a;
fetch c_a into :loc.arg1;
close c_a;
open c_b;
fetch c_b into :loc.arg2, :loc.arg3, :loc.arg4, :loc.arg5;
close c_b;
Thanks for your advices!
Maybe my solution is not right, if you have better ideas, please suggest :)
PS: If you need more details, please ask which you need.

Hi,
I don't think you can do exactly like that in APEX.
Go for a pipelined function if you want the value be returned from the function.

How do you pass parameters to a Pipelined function?

I am using Oracle 10G and the ODP .NET 32 bit client.
I am facing an issue trying to use variable binding with a pipeline function in Oracle. I am using ODP .NET for connecting to the database.
If you want to be familiar with PIPELINED functions, you can read [this blog.|http://oradim.blogspot.com/2007/10/odpnet-tip-using-pipelined-functions.html]
I have very similar code with a difference. My function takes in two parameters that I need to pass to get the table. This is working in SQLPLUS without any issues.
In my C# code, however things change. My function no longer returns a recordset (data reader), if I use the standard method of assigning the parameters.
The code will work if I concat the variables in a string.
Here is the example that doesn't work.
        static OracleDataReader fetchData(OracleConnection oc, string strPONumber)
            try
                OracleCommand od = oc.CreateCommand();

                od.CommandText = "select * from table(pkg_fetchPOInfo.getPORowsTable(:1,:2))";
                OracleParameter op1 = new OracleParameter();
                op1.ParameterName = "1";
                op1.OracleDbType = OracleDbType.Varchar2;
                op1.Direction = System.Data.ParameterDirection.Input;
                op1.Size = 7;
                op1.Value = strPONumber;
                od.Parameters.Add(op1);
                OracleParameter op2 = new OracleParameter();

                Console.WriteLine("Error " + e.ToString());
                return null;
        }Here is the example that does.

throw it into an anonymous block and it should work for you.

ORA-22905 with pipelined function

Hi,
I have a strange behaviour that I do not understand.
The code below does not work. It gives me the following errors:
ORA-22905: cannot access rows from a non-nested table item
ORA-06512: at line 10
ORA-06512: at line 19
The problem comes from the line 14 in that function
adm_usergroup.GET_GROUPIDS (userid_in)
If I replace the variable userid_in by its values then it perfectly works.
Can someone give me an explanation ?
The adm_usergroup.GET_GROUPIDS (userid_in) is a pipelined function that querry a group of tables and return IDs which are number.
A call to the function works fine as using it directly in a select statement.
Cheers,
Sebastien

Use of Pipelined Function in Forms10g(10.1.0.2)...

Hi ,
I test the routines found in http://sheikyerbouti.developpez.com/recordset/record_set.htm
I have a problem in the sample routine in Forms10g regarding pipelined function.
Whereas , the whole routine database part and client side in SQL*PLUS works fine.... the client side on Forms10g does not.......
I used two versions in when-button-pressed trigger:
1)Declare
        cur SYS_REFCURSOR ;
begin
       Open cur for SELECT * FROM TABLE(Pkg_Cur_.Get_Raws2(CURSOR(SELECT * FROM EMP WHERE DEPTNO = 10)));
end;
The error message in compilation time is..
Error 606: The subquery cursor is invalid in the client side
and the second version is:
2)Declare
      tab Pkg_Cur_.REC_EMP_;
begin
       tab:=Pkg_Cur_.GET_RAWS2('SELECT * FROM EMP WHERE DEPTNO = 10');
end;whereas the database package is defined as:
CREATE OR REPLACE PACKAGE Pkg_Cur_
IS
TYPE REC_EMP_ IS TABLE OF EMP%ROWTYPE INDEX BY BINARY_INTEGER ;
FUNCTION Get_Raws RETURN REC_EMP_ ;
FUNCTION Get_Raws2 ( cur_lig IN SYS_REFCURSOR )
    RETURN TYPE_TAB_REC_EMP_ PIPELINED ;
END Pkg_Cur_ ;and the database package body is as follows:
CREATE OR REPLACE PACKAGE BODY Pkg_Cur_
IS
FUNCTION Get_Raws RETURN REC_EMP_
IS
     TAB REC_EMP_;
BEGIN
     SELECT * BULK COLLECT INTO TAB FROM EMP ;
       RETURN TAB ;
END ;
FUNCTION Get_Raws2 ( cur_lig IN SYS_REFCURSOR )
RETURN TYPE_TAB_REC_EMP_ PIPELINED
IS
   Trec TYPE_REC_EMP_ := TYPE_REC_EMP_(NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL ) ;
   Remp EMP%ROWTYPE ;
BEGIN
   LOOP
     FETCH cur_lig INTO Remp ;
     EXIT WHEN cur_lig%NOTFOUND ;
       -- Handling datas --
       Trec.EMPNO    := Remp.EMPNO ;
       Trec.ENAME    := Remp.ENAME ;
       Trec.JOB      := Remp.JOB ;
       Trec.MGR      := Remp.MGR ;
       Trec.HIREDATE := Remp.HIREDATE ;
       Trec.SAL      := Remp.SAL * 1.1 ;
       Trec.COMM     := Remp.COMM ;
       Trec.DEPTNO   := Remp.DEPTNO ;
       -- Return value --
       PIPE ROW( Trec ) ;
   END LOOP ;
   RETURN ;
END ;
END Pkg_Cur_ ;
So , how the form trigger should be written...????
If somebody could help me i would be grateful...!!!!
Thanks a lot
Simon

In the second anonymous block you're trying to populate a record with a table. You would need to select from the function and either bulk collect into a table variable or fetch into a record variable in a loop. Bulk collect is also not supported on the client side.
I've been looking at pipelined function possibilities in another thread:
table functions
The problem you have is actually with the Cursor functions, not the Pipelined functions.

PL/SQL Pipelined Function to Compare *ANY* 2 tables

I am trying to create a pipelined function in 10g R1 that will take the name of two tables, compare the the tables using dynamic SQL and pipe out the resulting rows using the appropriate row type. The pipelined function will be used in a DML insert statement.
For example:
create table a (f1 number, f2, date, f3 varchar2);
create table b (f1 number, f2, date, f3 varchar2);
create table c (f1 number, f2, date, f3 varchar2);
create or replace TYPE AnyCollTyp IS TABLE OF ANYTYPE;
create or replace TYPE CRowType IS c%ROWTYPE;
create or replace TYPE CRowTabType IS table of CRowType;
CREATE OR REPLACE FUNCTION compareTables (p_source IN VARCHAR2, p_dest IN VARCHAR2)
RETURN AnyCollTyp PIPELINED
IS
CURSOR columnCur (p_tableName IN user_tab_columns.table_name%TYPE)
IS
SELECT column_name, column_id
FROM user_tab_columns
WHERE table_name = p_tableName
ORDER BY column_id;
l_cur sys_refcursor;
l_rec ANYTYPE;
l_stmt VARCHAR2 (32767);
BEGIN
l_stmt := 'select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_source;
l_stmt := l_stmt || ' minus ';
l_stmt := l_stmt || ' select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_dest;
OPEN l_cur FOR l_stmt;
LOOP
FETCH l_cur
INTO l_rec;
PIPE ROW (l_rec);
EXIT WHEN l_cur%NOTFOUND;
END LOOP;
CLOSE l_cur;
RETURN;
END compareTables;
The pipelined function gets created without error. However, the testCompare procedure gets an error:
SQL> create or replace procedure testCompare is
begin
insert into c
select *
from (TABLE(CAST(compareTables('a','b') as cRowTabType)));
dbms_output.put_line(SQL%ROWCOUNT || ' rows inserted into c.');
end;
Warning: Procedure created with compilation errors.
SQL> show errors
Errors for PROCEDURE TESTCOMPARE:
LINE/COL ERROR
3/4 PL/SQL: SQL Statement ignored
5/47 PL/SQL: ORA-22800: invalid user-defined type
Does anyone know what I am doing wrong? Is there a better way to compare any two tables and get the resulting rows?

Pipelined function with Union clause(Invalid Number(ORA-01722) error )

Hi,
I have a pipelined function.
I am fetching the data with the use of a REF cursor.
The query has two part: query1 and query2
when I am opeing the cursor with query1 UNION query2,it is giving me Invalid Number(ORA-01722) error.
but when I open the cursor separately for query1 and query2,I am getting the resultset for each of the query.
query1 and query2 are running fine with UNION in the sql editor.
But,when I put them into two variables (var1 :='query1' and var2:='query2' and try to open the cursor with var1 UNION var2 , it's giving me the error.
But when I put query2 as 'Select ..... from dual' and then try to open the cursor for query1 UNION query2,
then getting the result of query1 and one extra row for query2(dual).
The FROM table set is same for query1 and query2..
can anyone please help me , why this Invalid Number(ORA-01722) error is coming.

Pipelined function..please help

hi all...
i need a fuction which will split the data n insert into the table...
i created a fuction like this :

myCursor ref0;
out_rec SPLIT_TYPE := SPLIT_TYPE(null, null);
--CURSOR MSTFRC IS SELECT * FROM TEMP_SPLIT;
index_      NUMBER(10,0);

it created succesfully without errors but when i run this function it showing an error like cannot evaluate pipelined function..
my requirement is to split the data like 'as,af,er,yt' split this by comma n insert into the table with row id like
1 as
2 af
3 er
like...
please help friends....
thnks in advance...

function.
And that is one of the most important pieces of the puzzle - the actual error displayed. What is it? (full error, i.e. number + message)
As for the code in the function. That looks a bit like an ugly hack to me. Why the INSERT into table? Why not simply use a local collection or array?
And why a pipelined table function specifically?
The following code demonstrates a string split function:
SQL> create or replace type TStrings as table of varchar2(4000);
2 /
Type created.
SQL>
SQL> create or replace function tokenise( cString varchar2, cSeparator varchar2 DEFAULT ',' ) return TStrings AUTHID CURRENT_USER is
2 strList TStrings;
3 str varchar2(4000);
4 i integer;
5 l integer;
6
7 procedure AddString( cLine varchar2 ) is
8 begin
9 strList.Extend(1);
10 strList( strList.Count ) := cLine;
11 end;
12
13 begin
14 strList := new TStrings();
15
16 str := cString;
17 loop
18 l := LENGTH( str );
19 i := INSTR( str, cSeparator );
20
21 if i = 0 then
22 AddString( str );
23 else
24 AddString( SUBSTR( str, 1, i-1 ) );
25 str := SUBSTR( str, i+1 );
26 end if;
27
28 -- if the separator was on the last char of the line, there is
29 -- a trailing null column which we need to add manually
30 if i = l then
31 AddString( null );
32 end if;
33
34 exit when str is NULL;
35 exit when i = 0;
36 end loop;
37
38 return( strList );
39 end;
40 /
Function created.

Opening cursor to collection of records?

Hi,
I am researching an issue at work, and I wanted to see if any of you knew whether or not what I'm attempting to do is possible.
Essentially, what we have is a large number of stored procedures that return data in the form of OUT parameters. If there is more than 1 row, the procedures return a special integer, and the client code (a Java process) repeatedly calls the procedure until it gets all of the data.
We want to convert these procedures so that they return a result set (i.e., they will
return a reference cursor variable.) However, we'd rather not work directly with the procedures themselves. What we were hoping to do was develop a set of "proxy" procedures. Java calls these proxies, which call the original procedures, accumulating all the data. Then, the proxy opens a cursor to the final data set, so that in terms of network accesses, there is a single Java-side network access, and multiple local accesses on the Oracle end of things.
The problem is, I'm not sure that we can return a cursor to the data. What follows are the issues:
First, we can't open a cursor to the original function calls (AFAIK.) We have to somehow get all of the data from the function into the proxy, and open a cursor to that in the form of a SELECT on all of the data (from SYS.DUAL, or some similar method.)
So, I decided that maybe the answer was to use a collection. Logically, I thought it best to create a RECORD data type, with a pseudo-column for each of the OUT parameters in the original function call. Then, I created a nested table of these records. I call the original function from the proxy, populating this collection of records with all of the data. That works fine. However, I thought it would be relatively straightforward to open a cursor to this collection, using i.e.:
OPEN ref_cursor FOR
SELECT * FROM TABLE(CAST(my_collection_variable AS my_collection_table_type));
(Or some variant of that.) Unfortunately, it is not. This results in an Oracle error, when I actually open the
cursor:
ORA-00600: internal error code, arguments: [15419], [severe error during PL/SQL
execution], [], [], [], [], [], []
ORA-06544: PL/SQL: internal error, arguments: [pfrrun.c:pfrbnd1()], [], [], [],
ORA-06553: PLS-801: internal error [0]
ERROR:
ORA-24338: statement handle not executed
After some research, I found that I could not define the nested table at the PL/SQL level (All of these functions live in packages.) It had to be defined at the database SQL level. So I created a nested table of NUMBER variables at the SQL level (from within sqlplus), tested opening a cursor to that, and everything worked fine.
Then, I hit the next snag. I can't define the RECORD type at the SQL level, and I can't reference it from the nested table definition (which is defined at the SQL level) when it is defined at the PL/SQL level. This is the error for that:
1/29 PLS-00201: identifier 'REF_TYPES.FUND_RT' must be declared
(Where FUND_RT is a RECORD declared in package REF_TYPES.)
See below for the SQL scripts.
So, I would have to create literally hundreds of nested tables of VARCHAR2's, NUMBER's, etc., for each OUT parameter at the database level for this approach to work, which is not feasible.
Does anyone know of a work around for this situation? Is there a way to access a RECORD type defined at the package level, from within a SQL-level nested table
definition? Is there a way to accomplish what seems like a very simple task that I'm somehow missing?
Thank you,
Gabriel Weinstock
SQL to create the record type, executed first from sqlplus:
conn owner/password
CREATE OR REPLACE PACKAGE ref_types
AS
TYPE ref_cursor IS REF CURSOR;
TYPE fund_rt IS RECORD
( var1 NUMBER,
var2 VARCHAR2,
var3 DATE );
END;
grant execute on owner.ref_types to public;
** ("owner" is the owner of the table-- is that a problem? I tried "owner.REF_TYPES.fund_rt" and that didn't work either). **
Next, to create the collection, which generates an error, the following script is called from sqlplus:
conn owner/password;
CREATE OR REPLACE TYPE fund_tab_t AS TABLE OF ref_types.fund_rt;
Error, see above:
1/29 PLS-00201: identifier 'REF_TYPES.FUND_RT' must be declared

I agree with Stephen as well that given more time a rewrite of the stored procedures would be optimal.
Todd-- thanks for the answer. What had me baffled was that I don't think you can define a record at the SQL level, but an object is acceptable. Is that correct?
However, this raises more issues. I'm not sure management is going to go head over heels for all of these anonymous objects defined at the SQL level, not belonging to any package, so, as I looked further, I think I might have to use a "pipelined function". Which will mean one function calls the original stored procedure, and gathers up all the data into a collection of records. Then, it returns that collection. A second (!) function, opens a ref cursor for a SELECT that includes the returned collection from the first function.
This way, nothing has to be defined at the SQL level, and I can do everything in the package. (I'll probably eat my words on that.)
It definitely is NOT pretty, but it might be the way things turn out for an interim solution.

Maximum open cursors

Hi,
I have an application running on NT station versus Oracle 8.0.5 database on NT server.
I'm getting the ORA-01000 error while running a report. This error doesn't appear regulary while running the concerned report. it appears after calling the report several times (closing then opening).
After the error appear everytime I call the report this error appear until the user restart the PC. I did check the report and I'm closing the cursors I opened.
I had the open_cursors parameter in the INIT file set for 400 then I changed to 600 but this didn't change a thing (I restarted my database).
I'm using recursive functions but I'm always closing the cursors before calling the function recursively.
And I also want to notes that the recursive function depending on the data I have won't go more than 2 or 3 levels deeper.
Please confirm it is bug 492362: NT/95/3.1.1 - REPORTS DOES NOT RELEASE OPENED CURSORS. and how to fix it.
THANKS

Confused about Open Cursors :(

Hi all,
i need some clarification on this issue, i've read throught the documentation and i'm a bit confused.
I'm using 10.1.0.2
select sum(value)
from v$statname sn,
v$sesstat st,
v$session s
where sn.statistic# = st.statistic#
and st.sid = s.sid
and sn.name = 'session cursor cache count'
The result of the above query is 4926, meaning i have 4926 CLOSED cursors in the session cursor cache.
select count(1)
from v$open_cursor
The result of the above query is 16968, meaning i have 16968 cached cursors
So there are two distinct cursor Caches ?
now lets look at other statistic
select sum(value)
from v$statname sn,
v$sesstat st,
v$session s
where sn.statistic# = st.statistic#
and st.sid = s.sid
and sn.name = 'opened cursors current'
this one gives me 12212 , so i have 12212 opened cursors (NOT CACHED , REALLY OPENED CURSORS ...is this correct???)
I suspect that my applications are not closing resultsets (java build application, deployed in oracle application server, database connections in pooled connection) ... so i'm trying to help my developers to find the potencial bug in application.
How can i get the SQL from OPEN cursors ???
V$open_cursor gives me SQL from CLOSED cached cursors ...
Best Regards
Rui Madaleno

Hi,
>>this one gives me 12212 , so i have 12212 opened cursors (NOT CACHED , REALLY OPENED CURSORS ...is this correct???)
For your instance, yes because you use the sum(value) aggregate function. But I think that the best is get this value per session.
select count(1) from v$open_cursor
v$open_cursor shows cached cursors, not currently open cursors, by session. If you're wondering how many cursors a session has open, don't look in v$open_cursor. It shows the cursors in the session cursor cache for each session, not cursors that are actually open. To monitor open cursors, query v$sesstat where name='opened cursors current'. This will give the number of currently opened cursors, by session:
select a.value, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s
where a.statistic# = b.statistic# and s.sid=a.sid
and b.name = 'opened cursors current';
>>I suspect that my applications are not closing resultsets (java build application, deployed in oracle application server, database connections in pooled connection)
In this case, you need to monitor you application. If want, you can use the OEM Database Console and go to [Top Sessions | Session Details] link, or to use this SQL above.
By the way, do you are getting ORA-1000 errors ?
If so, set the OPEN_CURSORS parameter high enough that you never get an ORA-1000 during normal operations.
Cheers
