Pipelined functions and reports
Hi all,
please consider this test case:
create type htmldb_obj as object (
a varchar2(10),
b varchar2(10)
create type htmldb_type2 as table of htmldb_obj;
create or replace function htmldb_f2 (p number)
return htmldb_type2
pipelined
is
begin
pipe row ( htmldb_obj( to_char(p), to_char(p) ) );
return;
end htmldb_f2;
In a "pl/sql function returning SQL string" report, this works like a charm:
begin
return 'select * from table (htmldb_f2 (cast(:APP_ID as number)));';
end;
But when trying to select column "a" instead of all columns:
begin
return 'select a from table (htmldb_f2 (cast(:APP_ID as number)));';
end;
report error:
ORA-00904: "HTMLDB_F2": invalid identifier
Even if the statement is correct:
test2@ORACLE9I> variable app_id varchar2(10);
test2@ORACLE9I> exec :app_id := '3';
PL/SQL procedure successfully completed.
test2@ORACLE9I> select a from table (htmldb_f2 (cast(:APP_ID as number)));
A
3
I've tried a few variations (casting the set returned by the function, using an in-line view) but the result is always the same: legal sql statements in sqlplus always gets the 'ORA-00904: "HTMLDB_F2": invalid identifier' error.
Please note that i cannot simply hide the function in a view since i have to supply a parameter.
What's wrong ?
Thanks in advance
o This works:
begin
return 'select a from table (htmldb_f2 (cast(nv(''APP_ID'') as number)));';
end;
o This doesn't:
begin
return 'select a from table (htmldb_f2 (cast(v(''APP_ID'') as number)));';
end;
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-00904: "V": invalid identifier
O This works:
begin
return 'select a from table (htmldb_f2 (cast('|| nv('APP_ID') ||' as number)));';
end;
My preference is on the first method (better sql cache utilization).
a) Are you interested in the results I will get after applying the HTMLDB patch ?
b) out of curiosity - does HTMLDB use dbms_sql to describe the statement and get the columns info ?
Thanks Scott - I'm more than happy with the workaround!

Tabular forms based on pipelined functions - can it be done?
Hi there,
Pipelined functions are great, specially when you want to encapsulate the access to tables instead of just SELECTing from them (what I am doing a lot in my current project.)
However Apex 4 does not like them, at least not for tabular forms...
I want to handle myself the update/insert/delete process, so I don't need the MRU default functionality (all the access to the data is via APIs). But at the same time I want to just SELECT from my pipelined function and set the item types using the builder interface as with any tabular form (without having to use the apex_item API). Also I want to be able to use tabular form validation.
To start with, you can only create a tabular form based on a table or view. To overcome this issue, I created a dummy view with the fields I wanted and created my tabular form on it. Then I changed the FROM clause to FROM TABLE(myfunction). It didn't work as it seems it tries to select the ROWID for each row... Of course my pipelined function doesn't return one but I don't need one anyway as I will be doing the data manipulation myself based on the PK.
For this to work, I had to create a collection, populate it with the result of the pipelined function in a page process every time the page is loaded, create a view on that collection and base the tabular form on the view... A lot of work and overhead for something that should be very simple in principle.
Then, I found out that if I remove the default MRU process that is automatically created, the tabular form validations stop working (as I posted in another thread). So I have to leave a "dummy" MRU process there with condition = never for it to work.
The application I am working on is all based on API calls and pipelined functions so all this work has to be repeated for each tabular form that is needed.
If it was possible to base a tabular form directly on a pipelined function it would be such an elegant solution.
Is there a better way to implement this? Shouldn't Apex be more compatible with pipelined functions? (at least in regards to tabular forms, they work well with normal forms, reports, LOVs etc)
Thanks
LuisAs I mentioned before, I don't handle inserts (well, I cheat).... On my page, there is a form to set up a request - prompts for a few things, and when submitted, calls a stored procedure:
:P2_REQUEST_RESULT := Simon.Apex_Campus_Guest.Setup_Request(:P2_GROUP_NAME,
:P2_COAS_ORGN, :P2_START_DATE, :P2_END_DATE, :P2_Quantity, :P2_Generic_Names);
Which creates an APEX collection, which in turn is made visible via a pipelined function turned into a view:
create or replace view Apex_Campus_Guest_Request_va as
select seq_no,
user_name,
group_name,
comments
from table ( Apex_Campus_Guest.Request_Result )
I have a second region which is tabular form on a query - conditional on select 1 from Simon.apex_campus_guest_request_va (the view defined above).
When this submitted, I have standard MRU and MRD processes (Seq_No is the primary key). This then runs into the appropriate trigger - the update trigger is as follows:
trigger Apex_Campus_Guest_Req_Upd
instead of update on Apex_Campus_Guest_Request_va
for each row
declare
cg_rec campus_guest_maint.rec;
begin
cg_rec := Campus_Guest_Maint.Request(
name => :new.user_name,
group_name => :new.group_name,
comments => :new.comments);
end;I don't know off hand why it isn't asking for a rowid - but may be that I specified a PKEY column. The insert case fails, as it tries to add a "Returning" statement in the original select. I actually find that annoying as a function is defined to allocate the PKEY from a sequence, so it doesn't need to ask for it that way. -
Apex can't parse query on pipelined function
Hi,
I have a report based on a sql query which selects from a pipelined function. The pipeline function and the collection sql type it returns live in the parsing schema of the application.
I get the error: "Query cannot be parsed within the Builder." There is no ORA-xxxxx message.
If I check "generic columns" (parse at runtime), and run, it says "ORA-00904 <name of pipelined function>: invalid identifier".
If I qualify the name of the pipelined function with the schema name, it works.
Or, if I replace the bind variables with literals, it works.
Or, if I replace the columns with *, it works.
I'm using Apex 2.0
Does anyone have an ideas why I am seeing this behaviour?marnold,
Can you show the query you're using in your report?
I have used pipelined functions many times, you can see an example of how I've used them here -
http://jes.blogs.shellprompt.net/2006/05/25/generic-charting-in-application-express/
and I haven't encountered any significant problems. -
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?

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?

What is the role of the RETURN clause in a pipelined function?
I wrote several pipelined functions and they work just fine without the return clause. However in the oracle's documentation there are returns in the pipelined functions:
CREATE FUNCTION StockPivot(p refcur_pkg.refcur_t) RETURN TickerTypeSet
PIPELINED IS
out_rec TickerType := TickerType(NULL,NULL,NULL);
in_rec p%ROWTYPE;
BEGIN
LOOP
FETCH p INTO in_rec;
EXIT WHEN p%NOTFOUND;
-- first row
out_rec.ticker := in_rec.Ticker;
out_rec.PriceType := 'O';
out_rec.price := in_rec.OpenPrice;
PIPE ROW(out_rec);
-- second row
out_rec.PriceType := 'C';
out_rec.Price := in_rec.ClosePrice;
PIPE ROW(out_rec);
END LOOP;
CLOSE p;
RETURN;
END;
/http://docs.oracle.com/cd/E11882_01/appdev.112/e10765/pipe_paral_tbl.htm#CHDJEGHC
Moreover, at least in PL/SQL developer I recieve hints that my pipelined functions return no values, though as I said the functions work smoothly. So is there a need in the return clause in pipelined functions or it is redundant?
My oracle version is 11.2.0.2.0As already mentioned, in later versions of the database it doesn't appear to be necessary, however, it IS good programming practice (and necessary in non-pipelined functions) to always ensure a function has a RETURN statement in it. It could be a 'side effect' (read that as bug if you like) that it doesn't appear to be necessary, so you would be best to ensure you DO include a RETURN statement, as documented.

Pipeline functions - what happens under the hood? (10g)
Hi all,
What happens when you call a pipelined function? (As opposed to a plain table-valued function.)
From what I understand, a pipelined function will return rows as they are needed. Let's say I have a really silly example of a pipelined function,
CREATE OR REPLACE PACKAGE BODY TEST_PACKAGE_1
AS
FUNCTION GET_DATA RETURN JUST_A_TABLE PIPELINED
IS
BEGIN
PIPE ROW (JUST_A_TYPE('HELLO'));
PIPE ROW (JUST_A_TYPE('WORLD'));
RETURN;
END;
END TEST_PACKAGE_1;
/Then let's say I were to SELECT * FROM TABLE(TEST_PACKAGE_1.GET_DATA) WHERE ROWNUM = 1, what happens to the second row? Does the code that returns the second row still get educated? (Obviously it's omitted from the query, but does it still get generated somewhere and just go nowhere?)
If I have a cursor on a PL/SQL block that selects from GET_DATA, will each row only be returned as the cursor references it? In that case, what happens to the rows that don't get selected? If there some resource that need to be closed out (say, just before the return statement), would it still be safe to close it out?
Thanks!
DonInteresting question, lets try a simple test and see we'll just take your example function and toss in a few dbms_output statements like so:
CREATE OR REPLACE PACKAGE BODY TEST_PACKAGE_1
AS
FUNCTION GET_DATA RETURN JUST_A_TABLE PIPELINED
IS
BEGIN
dbms_output.put_line('ONE');
PIPE ROW (JUST_A_TYPE('HELLO'));
dbms_output.put_line('TWO');
PIPE ROW (JUST_A_TYPE('WORLD'));
dbms_output.put_line('THREE');
RETURN;
END;
END TEST_PACKAGE_1;Now not forgetting to enable dbms_output call it three times like so:
SELECT * FROM TABLE(TEST_PACKAGE_1.GET_DATA) WHERE ROWNUM = 1;
SELECT * FROM TABLE(TEST_PACKAGE_1.GET_DATA) WHERE ROWNUM <= 2;
SELECT * FROM TABLE(TEST_PACKAGE_1.GET_DATA) WHERE ROWNUM <= 3;What I saw from my test was that with the first call I got 1 row of data from the pipelined function and only the first dbms_output statement was processed. For the second statement I got 2 rows of data from the function and the first two dbms_output statements were processed. For the final call I again got 2 rows of data from the function and all 3 dbms_output statements were processed.

Can anyone help me to get started writting a pipelined function to convert a table like this
Name Period start Period End
Smith 3 5
Smith 7 10
Smith 12 16
into a table tike this
Name Periods
Smith ooXXXoXXXXoXXXXXooooo
or may be there is a simpler way of doing this?
Thanks
David HillsThere's more to this problem than simple column concatenation. There is some processing reuired to fill the gaps between the start and end points of the periods.
The following code takes a blunt instrument approach: pipelined function and bit masks. Perhaps some of the brains on this forum can come up with a more elegant approach. The function does, at least, have the virtue of working:
SQL> select * from table( timelines)
2 /
NAME TIMELINE
Jones oooXXXXXooXXoooooooXXXXX
Smith ooXXXoXXXXoXXXXXoooooooo
SQL>Note that this code is very much a "coffee time" proof of concept, and contains a number of infelicitous repetitions. Improving this code is left as an exercise for the reader.

Debugging Pipelined function in SQLDeveloper
Hi All,
I have a pipelined function and I am trying to process the rows returned from the function within a cursor. The basic layout of the PROCEDURE IS
CURSOR C1 IS
SELECT * FROM TABLE(tab_function(CURSOR(SELECT * FROM MYTAB)));
BEGIN
FOR R1 IN C1 LOOP
INSERT R1 INTO MYTAB2
END LOOP;
END;
When I run this in SQL*PLUS the procedure, works for while until it hits a genuine bug.
However, if I try to debug the procedure in SQLDeveloper, it processes the first row correcly. But when it returns to the FOR..LOOP statement for the second row it falls over.
I am inserting into a table within the loop but this is outside of the table function which should (at least in this case) behave as a normal table.
Can anybody please help?

Pipelined functions with spatial data
hi,
i've been trying to use pipelined functions (using the TABLE and CAST operators to query data from them) to retrieve large amounts of spatial data.
i've followed the examples on metalink, and they work fine. my problem arises when i apply similar functions to query data using SDO_FILTER, i've been trying to pipe a mdsys.sdo_geometry datatype (ref cursor) into the function - returns null.
are spatial datatypes supported for use in pipelined functions, and using the table and cast operators?
if they are, where can i find further reading/reference on the subject?
thanks

FROM TABLE (TEST_FUNC)
We can see error ORA-01007 after refresing (or submiting) Page 1 three times or more.
How to fix it?Hi all
I'm experiencing the same issue. Predictably on every third refresh I receive:
Error
Error during rendering of region "Results".
ORA-01007: variable not in select list
Technical Info (only visible for developers)
is_internal_error: true

OK
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)
RETURN list_row_table_type
AS
v_tab list_row_table_type := list_row_table_type();
BEGIN
DECLARE
jsonarray json_list;
jsonobj json;
json_clob CLOB;
BEGIN
SELECT clob001
INTO json_clob
FROM apex_collections
WHERE collection_name = p_collection_name;
jsonobj := json(json_clob);
jsonarray := json_ext.get_json_list(jsonobj, 'predictions');
FOR i IN 1..jsonArray.count
LOOP
jsonobj := json(jsonArray.get(i));
v_tab.extend;
v_tab(v_tab.LAST) := list_row_type(json_ext.get_string(jsonobj, 'description'), json_ext.get_string(jsonobj, 'reference'));
END LOOP;
RETURN(v_tab);
END;
END AUTOCOMPLETE_LIST_VIEW_FNC;
Thanks!

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. -
Forms and Reports: Automated Test tools - functionality AND performance
All,
I'm looking to get a few leads on an automated test tools that may be used to validate Oracle forms and reports (see my software configuration below). I'm looking for tools that can automate both functional tests and performance. By this I mean;
Functional Testing:
* Use of shortcut keys
* Navigation between fields
* Screen organisation (filed locations)
* Exercise forms validation (bad input values)
* Provide values to forms and simulate user commit, and go and verify database state is as expected
Performance Testing:
* carry out tests for fixed user load
* carry out tests for scaled step increase in user load
* automated collection of log files and metrics during test
So far I have:

Thanks in advance for your response.

Configuration:
Red Hat Enterprise Linux x86-64 architecture v4.5 64 bit
Oracle Application Server 10.1.2.0.2 ( with patch 10.1.2.3 )
Oracle Developer Suite (Oracle Forms and Reports) V10.1.2.0.2 ( with patch 10.1.2.3 )
Oracle JInitiator 1.3.1.17 or later
Microsoft Internet Explorer 6are there any tools for doing this activity like oracle recommended tools?
Your question is unclear. As IK mentioned, the only tool you need is a new version of Oracle Forms/Reports. Open your v10 modules in a v11 Builder and select Save. You now have a v11 module. Doing a "Compile All PL/SQL" before saving is a good idea, but not required. The Builders and utilites provided with the version 11 installation are the only supported tools for upgrading your application. If you are trying to do the conversion of many Forms files in a scripted manner, you can use the Forms compiler in a script. Generating new "X" files will also update the source modules (fmb, mmb, pll). See MyOracleSupport Note 955143.1
Also included in the installation in the Forms Migration Assistant. Although it is more useful to people coming from older versions, it can also be used to move from v10 to 11. It allows you to select more than one file at a time. Documentation for this utility can be found in the Forms Upgrade Guide.

Fahad"I noticed that when I publish apk from Flash I don't have option to select path to android SDK below 2 checkboxes ( install app on device and run app on device after publishing)"
Are you saying the 2 checkbox's are missing? If so ,(or even if not), perhaps you don't have the latest extension installed in flash?
http://labs.adobe.com/technologies/flashpro_extensionforair/
I had an issue like you describe before. Everything was updated with my machine and phone, usb debugging , allow installation of non market apps... but i was not able to manually install my own apk's on my device.
If i were to put the .apk on my server or just drag it to the phone via USB i could not install it. it was "untitled" or "unknown" i forget.
The only way it would work was on export "install application on the connected android device".
However If i took anyone else's .apk made from flash, i could install it from my server or via usb drag/drop.
Even at one point someone on the forum posted an apk and the source .fla
Installed that apk? = YES
Export the same .fla myself with no changes = FAIL to install (unless launching directly from flash).
I was using windows xp, I happen to be upgrading my cpu last month so i installed windows 7 and re-installed flash, and now it works fine. I never figured it out. I was somehow producing non-viable .apks . However it works now and I have done nothing different (besides going from xp to win7 and reinstalling flash).
"other air apps (from other ppl) work both on phone and device."
I'm guessing you only installed other air4android apps from the market?
If you haven't tried yet, i could email you a .fla and .apk, see if you can install that from your ftp. Then re-export if yourself and see if it fails again?
