Pipeline function
Hello Gurus,
can any one please help me with pipeline and bulk collect, I am not able to find any example on the net with both.
I'm not arguing that it is never appropriate to use both constructs together. Just that, without more information, it's relatively rare that it would be worthwhile to use both.
In 10g, implicit cursors are already doing BULK COLLECTS with a LIMIT of 100, which is adequate for 99%+ of applications out there. The benefit to doing BULK COLLECT these days (unless we're talking about 9i development) is the ability to do a FORALL and other collection operations, but I don't see how you'd do a FORALL in the context of a pipelined table function and there is relatively little utility in doing collection operations in a pipelined table function, particularly when you're dealing with too many rows to store in the collection all at once.
Now, this is not to say that it's never a good idea to use the two constructs together-- I did so myself over the weekend-- just that I would tend to suspect that someone asking for examples of using both together is either dealing with some unusual requirements or is potentially confused about what they're asking for.
Justin
I will say, though, that my choice of the term "cross purposes" was poorly chosen in this context. What I intended to convey was more along the line of what I wrote here-- that while it's possible for and potentially perfectly appropriate for the two constructs to coexist, it is relatively unusual. Thanks for calling that out ABB.

Interactive Report using a View with a Pipelined Function
Hello fellow Apex people,
I'm Using Application Express 4.1.0.00.32
I've got an interactive report that references a view (STOCK) and a pipelined function
The basic query is listed below.
SELECT S.CHANGED_TIME "Changed Time"
, S.CHANGED_BY "Changed By"
, S.ID "Id"
, STKST_DESCRS.STOCK_STATUS_CODES "Stock Status Codes"
, STKST_DESCRS.STOCK_STATUS_DESCRS "Stock Status"
, S.ORIGINAL_CONTAINER "Original Container"
FROM STOCK S
, table(LWS_StkstStatus (S.ID)) STKST_DESCRS
ORDER BY S.CO_ID,
S.SEQUENCE_NUM;
When the page is first run all the data is displayed correctly,
If I define a filter, sort or a blank search the data from the pipelined function (STKST_DESCRS.) becomes null and isn't displayed.
Does anyone know what is happening?
Many ThanksI'm curious why you find this dangerous. I want a report that looks like this:
Opportunity X:
4 - 2-apr-2008 - Closed deal
3 - 1-mar-2008 - Called Joe again
2 - 12-feb-2008 - Called Joe
1 - 14-jan-2008 - Initial call with customer.
When you enter a new note, I want it to be numbered 5. The only problem I can imagine is someone deleting a note, which will almost never happen, and if it does, it just leaves a numbering gap. I don't see how using the function in a SELECT will accomplish this. -
Hi!
I have a problem with List View Report in mobile application (theme 50 in apex) after updating to apex 4.2.2. I created Report -> List View. I used select from pipelined function in Region Source. Then when page is running and submited three times (or refreshed three times) I get an error:

I am running Application Express 4.2.2.00.11 on GlassFish 4 using Apex Listener 2.0.3.221.10.13.
Please note: this works perfectly using a classic report in my desktop application; however, no joy on the mobile side with a list view. I will use a classic report in the interim.
My region source is as follows:
SELECT description AS "DESCRIPTION", reference AS "REFERENCE" FROM TABLE(AUTOCOMPLETE_LIST_VIEW_FNC('RESULTS'))
The procedure:
FUNCTION AUTOCOMPLETE_LIST_VIEW_FNC(
p_collection_name IN VARCHAR2)

Pipelined function with lagre amount of data
We would like to use pipelined functions as source of the select statements instead of tables. Thus we can easily switch from our tables to the structures with data from external module due to the need for integration with other systems.
We know these functions are used in situations such as data warehousing to apply multiple transformations to data but what will be the performance in real time access.
Does anyone have any experience using pipelined function with large amounts of data in the interface systems?It looks like you have already determined that the datatable object will be the best way to do this. When you are creating the object, you must enter the absolute path to your spreadsheet file. Then, you have to create some type of connection (i.e. a pushbutton or timer) that will send a true to the import data member of the datatable object. After these two things have been done, you will be able to access the data using the A3 - K133 data members.

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.CommandType = System.Data.CommandType.Text;
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();
op2.ParameterName = "2";
op2.OracleDbType = OracleDbType.Varchar2;
op2.Direction = System.Data.ParameterDirection.Input;
op2.Size = 3;
op2.Value = "US";
od.Parameters.Add(op2);
OracleDataReader or = od.ExecuteReader();
return or;
catch (Exception e)
Console.WriteLine("Error " + e.ToString());
return null;
}Here is the example that does.
static OracleDataReader fetchData(OracleConnection oc, string strPONumber)
try
OracleCommand od = oc.CreateCommand();
string formSQL = "Select * from table(pkg_fetchPOInfo.getPORowsTable('"+strPONumber+"','US'))";
od.CommandType = System.Data.CommandType.Text;
od.CommandText = formSQL;
OracleDataReader or = od.ExecuteReader();
return or;
catch (Exception e)
Console.WriteLine("Error " + e.ToString());
return null;
}throw it into an anonymous block and it should work for you.

Turning sql string (with dynamic columns) into a pipelined function
Hi guys,
I was working on an apex report the other day, and wrote the sql below (for those who don't know apex well, in an apex report you can define the columns at runtime.) When I was finished, I said to myself: "It would be great to have a pipeline function with this capability." So, the idea would be to have a sql string where the columns are created dynamically, depending on input parameters - and then be able to use this sql everywhere (oracle reports, sqlplus) through a pipelined function.
Here's the sql (simplified, of course, the data itself is actually not important - the LOOP is the key)
declare
v_sql varchar2(4000);
begin
v_sql := 'select client, ';
for i in (select employee from company_employees_view where condition = pi_parameter order by 1) loop
v_sql := v_sql || sum(decode(employee,''' || i.employee || ''', total)) "' || i.employee || '"';
end loop;
v_sql := v_sql || ', sum(total) "Total"';
v_sql := v_sql || ' from company_employees_view group by client';
end;
This sql would result in a final product like:
select client
, sum(decode(employee,'John',total) "John"
, sum(decode(employee,'Paul',total) "Paul"
, sum(decode(employee,'George',total) "George"
(and so on... this sql could have more or less columns depending on the input parameters of the function)
from company_employees_view
group by client;
I have tried feeding this sql into a ref cursor and an object, but always received an "inconsistent datatypes" message.
The object would be something like:
create or replace object rt_employee as (total number);
create or replace tt_employee as table of rt_employee;
create or replace object rt_client as (
client varchar2(100),
employee tt_employee);
create or replace tt_client as table of rt_client;
(I am not paying too much attention to syntax here.)
By the way, no hurry whatsoever, this is just for fun, take your time. I am using database XE with apex 2.1 and sql developer 1.2.
Thanks, RogerThis is the only solution I've ever seen to dynamic pipelined columns...

Pass multiple values as single input parameter into pipelined function
Hi all,
My need is to pass multiple values as single input parameter into pipelined function.
For example - "2" and "3" are values of input parameter "t":
with data as (
select 1 as t from dual union all
select 2 as t from dual union all
select 3 as t from dual union all
select 4 as t from dual union all
select 5 as t from dual
select * from data where t in (2,3)Is it possible at all?Not exactly sure, but usually 'multiple values'+'pipelined function' = some IN-LIST related approach?
See:
SQL> create table data as
2 select 1 as t from dual union all
3 select 2 as t from dual union all
4 select 3 as t from dual union all
5 select 4 as t from dual union all

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 )

END Pkg_Cur_ ;and the database package body is as follows:
CREATE OR REPLACE PACKAGE BODY Pkg_Cur_

So , how the form trigger should be written...????
If somebody could help me i would be grateful...!!!!
Thanks a lot
SimonIn 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. -

Thank you for your time in reading this post
RThank you Billy and Saubhik,
I have followed your guidelines and was able to resolve this error. Now, after successfully compiling the code, I attempted to execute it in a following way.
SELECT * FROM TABLE (cxs_generate_plsql_profiler);It gives following error: ORA-00904: "CXS_GENERATE_PLSQL_PROFILER": invalid identifier
I also tried putting in quotes like below
SELECT * FROM TABLE ('cxs_generate_plsql_profiler');Then, it gives following error:
ORA-22905: cannot access rows from a non-nested table item
Any Idea where I am doing wrong?
Thanks,

Hi,
Can any body tells when to use PIPELINE function in simple words.

Correct question - WHAT is a pipeline table function.
If you understand WHAT it is, you will be able to determine WHEN to use it.
So have you read the documentation? Tried coding your own pipeline function? Do you understand what it is and how it works? -
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

Does anyone know what I am doing wrong? Is there a better way to compare any two tables and get the resulting rows?904640 wrote:

Pipelined function ignores DML changes on subqueries
Hello all,
I have a really specific issue when using a pipelined function used in a complex subquery where the function ignores the changes made on the current transaction. The problem is the hidden hint materialize sometimes used by the Oracle optimizer. I say sometimes because it depends mostly on the execution plan and the complexity of the query.
I can repeat the problem with a dummy scenario.
Let's say we have a dummy table with a simple record :
CREATE TABLE DUMMY ("NAME" VARCHAR2(50 BYTE));
INSERT INTO DUMMY VALUES('Original name');
We then create a package which will contain our pipelined function and its record object and collection:
CREATE OR REPLACE PACKAGE PKG_DUMMY AS
TYPE DUMMY_RECORD IS RECORD (NAME VARCHAR2(50 BYTE));
TYPE DUMMY_RECORDS IS TABLE OF DUMMY_RECORD;
FUNCTION FUNC_GET_DUMMY_NAME RETURN DUMMY_RECORDS PIPELINED;
END PKG_DUMMY;
CREATE OR REPLACE
PACKAGE BODY PKG_DUMMY AS
FUNCTION FUNC_GET_DUMMY_NAME RETURN DUMMY_RECORDS PIPELINED AS
BEGIN
FOR CUR IN ( SELECT * FROM DUMMY )
LOOP
PIPE ROW (CUR);
END LOOP;
END FUNC_GET_DUMMY_NAME;
END PKG_DUMMY;
With this SQL query, we can return the value of the table by the pipelined function :
WITH DUMMY_NAME AS
SELECT "NAME"
FROM TABLE(PKG_DUMMY.FUNC_GET_DUMMY_NAME())
SELECT "NAME"
FROM DUMMY_NAME
Result
Original name
If we modify the DUMMY table with a new name without a commit, and re-execute the query, we got the same result :
UPDATE DUMMY SET "NAME" = 'New name';
Result
New name
But if we add the materialize hint in the subquery (without doing a commit or rollback), we have the original value hence my issue :
WITH DUMMY_NAME AS
SELECT /*+ materialize */ "NAME"
FROM TABLE(PKG_DUMMY.FUNC_GET_DUMMY_NAME())
SELECT "NAME"
FROM DUMMY_NAME
Result
Original name
I know I can force my subquery to use an inline hint instead of the "materialize" hint chose by the optimizer but then the query lose a lot of performance. Is there a way to force Oracle to use current DML changes with the materialize hint on a pipelined funtion in a subquery?
This thread is also for this issue : http://stackoverflow.com/questions/1597467/is-using-a-select-inside-a-pipelined-pl-sql-table-function-allowedHi Eliante, Hi Dominic,

16 rows selected.I can point out that the TABLE ACCESS FULL of the global temporary SYS_TEMP_0FD9D780C_BD7649E3 table created by Oracle in response to the -materialize hint is returning *0 rows* in operation 5.
Why?
It seems for me that the reason for that comes from the fact that the creation of this SYS_TEMP_0FD9D780C_BD7649E3 table is done via direct path read/direct path write and as far as
the insert of *'Original name'* has not been pushed yet into the disc then materializing the query will generate an empty temporary table (empty in this case).
This is why if I had committed I will not have seen such a kind of discrepancy between those two queries
What do you think?

Hello Experts,
I have created a Pipe lined function with execute immediate, due to below requirement;
1) Columns in where clause is passed dynamically.No, that's something you've introduced, and is due to poor database design. You appear to have columns on your table called FPD1, FPD2 ... FPD31. The columns do not need to be 'passed dynamically'
2) I want to know the data stored into above dynamic columns.And you can know the data without it being dynamic.
3) I want to use it in report, so I don't want to insert it into a table.That's fine, though there's no reason to use a pipelined function.
You also have an pointless exception handler, which masks any real errors.
I'm not quite sure what the point of your "connect by" is in your query as we don't have your tables or data or know for sure what the expected output is.
However, in terms of handling the 'dynamic' part that you've introduced, then you would be looking at doing something along the following lines, using a static query that requires no poor dynamic code, and no pipelined function...
