Use of Oracle global temp table in BI Publisher

Hi All,
I have witten a function which populates a Gobal temp table.I call the function and do a select on the global temp table.This fails to give me any result.
We are calling the function within the package in the 'beforeReport' trigger in our Data Template in BI Publisher.
I tried to check the session id and found that the sessions are different when we execute the functiona and when we do a select query.
How can I avoid this situation of changing session?
I have tried by removing commit from the function but even thta didnt help.
Please let me know if anyone has suugestion on this.
Thanks in advance!

Hi,
To check if the function is working fine , we inserted the output from temp table into a normal physical table .We queried the physical table and found the values there.
So , the function is working fine.
We dont have any statement like 'PRAGMA AUTONOMOUS_TRANSACTION ' in our function.
Do we need to add it?
Just to clarify the issue , We have populated the temp table by calling a function and after that we are trying to query the temp table.However, it appears that the session changes between teh function call and issuing of select query .This is resultin into no data being fetched as the values in Gloabal temp table persist only for a session.
Thanks!

Can a tabular form be created/used against a GLOBAL TEMP TABLE?

We are trying to simplify our apex applications. In doing so, we are examing the many collections we use to create tablular forms. These collections currently are tricky to manage and we are considering moving them to either VIEWS or GLOBAL TEMPORARY TABLES (GTT).
I have created a test app against a GLOBAL TEMP TABLE....it looks great, but when I add a row and SUBMIT I recieve a message indicating record is inserted....but where did it go? I am unable to retrieve...I cannot see it in the underlying GLOBAL TEMP TABLE (as expected)....
should I be creating an ON INSERT table on the GTT to automatically insert the data into a regular table?

Now you know why you have to use collections :) Answered here:
working with global temp table and apex
Has to do with the session management and how APEX handles it.
Create a view on your collection using the column names from the source table. Use packages to write an update, delete and insert process. This can be written automatically if there are multiple collections to handle.

Is it possible to load and read from an Oracle global temp table?

Is there a way to call an Oracle database package to pre-load global temp tables in BIP? I am an Oracle Reports user but a newbie to BIP. In Oracle Reports, I use the before-reports trigger to execute a database package that will populate a temp table with data. Then, in Oracle Reports, I read the temp table as the report data source. In BIP, I cannot find the ‘before-reports trigger’ equalivant. Since all the complicated business logic is contained in package it would be helpful to bring in the loaded temp table into BIP. Any thoughts?
Example:
Step 1. In the Oracle Reports before report trigger : exec db_package.load_temp_table_procedure (:var1, :var2, :var3);
Step 2: Select * from temp_table.

Look at Datatemplates,
It has pre and post report trigger,
You can do all these stuff over there,

How can I get rid of Global Temp Table

Hello,
I've been writing PL/SQL stored proc for creating reports on VB.NET front end. Until now, I've been using session specific global temp table to store intermediate results and at the end I pass the result set to .NET via reference cursor. The reports are created by simply binding the ref cursor result sets to .NET grids. It's been working fine, but I am kind of bothered by the temp tables. I looked on other options, but couldn't really come up with one.
Can somebody suggest me how I can get rid of those temp tables? Thanks,

Tubby, that's exactly I was trying to do. I think that table type has to be defined in database, not within PL/SQL. How can I create that table of user defined record type? I tried that, but it doesn't allow me. I think I am missing something. For example,
create type group_t is record
(A varchar2,
B number,
C number)
now inside sp, i have something like:
type my_group is table of group_t index by binary_integer
now I have sp cursor as
cursor cur_test IS 'ABC' as A, 1 as B, 5 as C
now i do something like this. My original queries are longer and much more complicated so please don't suggest you can directly open ref cursor for this query.
FETCH cur_test BULK COLLECT INTO my_group;
Then I do all the processing, calculations, totals, sub-totals, and insert into temp table and return via ref cursor.
My problem is I can't directly fetch into the above table you mentioned. How should I go about in this situation?
Maybe I should STOP thinking about this approach and just do whatever I've been doing or solve it through pure SQL. However, there are tons of problems with pure SQL approach.

Use global temp table for DML error logging

our database is 11.2.0.4 enterprise edition on solaris 10
we are wondering if anyone has an opinion of or has done this before, to use a global temp table for DML error logging. We have a fairly busy transactional database with 2 hot tables for inserts. The regular error table created with dbms_errlog has caused many deadlocks which we don't quite understand yet. we have thought using global temp table for the purpose, and that seemed to work, but we can't read error from the GTT, the table is empty even reading from the same session as inserts. Does anyone have an idea why?
Thanks

The insert into the error logging table is done with a recursive transaction therefore it's private from your session which is doing the actual insert.

Update Global Temp Table in Oracle 11g

Hi Experts,
Scenario: I have stored procedure A which calls procedure B. Procedure B uses Global temp Tables(With On Commit Preserve Rows) to work with the data.
I am trying to update one of the GTT in Proc B but unable to do it .. via SQL or via PL/SQL Cursor/Collection. There is no syntax nor logical error and the PL/SQL proc completes execution successfully but the rows are not getting updated. My Db version is Oralce 11g 11203.
Update statement is something like this.
Update <GTT>
SET amount1 = amount1 *-1, amount2 = amount2 *-1
where field1 = <value>
and field2 in ( Select filed2 from <table1> );
Any idea why would this update not work? Has anyone faced this issue in Oracle 11g??
Appreciate your suggestions & thanks in Advance for your inputs.
Cheers,
MS

where field1 = <value>
and field2 in ( Select filed2 from <table1> );

You already told us that it DOES work - no errors or exceptions.
It is trivial to determine if that update will do anything - just turn it into a SELECT and see if any rows are ntselected:
v_cnt INTEGER;
SELECT COUNT(*) INTO v_cnt FROM myGTT
WHERE field1 = <value>
AND field2 in (Select field2 from <tablee1>);
Then take a look at the 'count' that you get.

Global temp table in Oracle EBS

hi gurus,
i have a GTT with "ON COMMIT PRESERVE ROWS".
i am populating this table through an OAF page and displaying the data.
as per the documentation it should delete the data from the table once user logs out from the Oracle EBS but it's not happening.
the user still sees the records from the previous session.
please throw some light here.
thanks,

i was wondering if there is any sysadmin level setup/profile setup which can end the session (JDBC) once user logs out?No such profile option exists.

Global Temp Table Data Deleted Before Use

Hi All,
My application sends query to Procedure as input by using which data is inserted in Global Temp Table but when want to use inserted data in Application there are no records in table.
There is no implicit or explicit Commit after data insertion. If I use ON COMMIT PRESERVE ROWS option during global table creation, still records are deleted from temp table .....Application don't gets records.
What may be other reasons.
Thanks in Advance.
Rakesh-India

bro u need to explicity use COMMIT for preserve transactions. the clause for the global temporary table states ON COMMIT; meaning if u commit ...got it now.
explicitly commiting the transactions after insert worked.
Now the global temp tab are session based, other user session cannot access the inserted rows.
If commiting the transaction doesn't work then u should retrieve the inserted rows within the procedure or at the end of the proc code the data may be truncated... but commiting the transactions should work easily.

Multiple users accessing the same data in a global temp table

I have a global temp table (GTT) defined with 'on commit preserve rows'. This table is accessed via a web page using ASP.NET. The application was designed so that every one that accessed the web page could only see their data in the GTT.
We have just realized that the GTT doesn't appear to be empty as new web users use the application. I believe it has something to do with how ASP is connecting to the database. I only see one entry in the V$SESSION view even when multiple users are using the web page. I believe this single V$SESSION entry is causing only one GTT to be available at a time. Each user is inserting into / selecting out of the same GTT and their results are wrong.
I'm the back end Oracle developer at this place and I'm having difficulty translating this issue to the front end ASP team. When this web page is accessed, I need it to start a new session, not reuse an existing session. I want to keep the same connection, but just start a new session... Now I'm losing it.. Like I said, I'm the back end guy and all this web/connection/pooling front end stuff is magic to me.
The GTT isn't going to work unless we get new sessions. How do we do this?
Thanks!

Global Temp Table or PL/SQL Table

I am trying to determine if this can be done only using PL/SQL table. If not, will the usage of the global temp table affects the performance.
Here is the situation,
I have a data block that is based on a stored procedure. This stored procedure will return table of records from different database tables with join conditions. Some of the fields within the table of records will not have data returned from database tables. They will be the fields displayed on the form and the data will be entered by user.
For example:
Records will look like:
Id          (will be populated by procedure)
Hist_avg     (will be populated by procedure)
My_avg     (will be used as field on the form so that user can enter their own avg)
Cheked     (will be populated by procedure)
My questions are:
1.     Is this doable in form using a data block based on PL/SQL table?
2.     Will users be able to manipulate (update) the data that based on the PL/SQL table in the memory as they wish and invoke the procedure to update the underlying table when clicking on a button (Update Avg)?
3.     What is the advantage of using PL/SQL table and global temp table from database and form point of views?
Any info is appreciated.

Global temp table problem w/ODP?

I'm using the current version of the ODP .NET data adapter to access a global temporary table on an Oracle
9.2.0.4.0 server created with -
CREATE GLOBAL TEMPORARY TABLE euik_dex_open_tasks_temp1
(resource_id NUMBER,
task_assignment_id NUMBER,
task_id NUMBER,
incident_id NUMBER,
customer_product_id NUMBER,
inventory_item_id NUMBER,
contract_service_id NUMBER)
ON COMMIT DELETE ROWS
(See below for what is returned from the data dictionary for this table)
If I use SQLPlus to insert a row into this table, then query the table immediately, I see the inserted row.
If I use the same exact SQL through the ODP adapter, the ExecuteNonQuery statement returns the fact the 1 row was inserted. However, doing a SELECT from the table immediately after the INSERT, no rows are returned. See the .NET test ap, below.
Also, note that if I use a global temp table made with ON COMMIT PRESERVE ROWS, the ODP adapter works fine.
What am I doing wrong? Thanks in advance...

Andrew,
As David indicated if you do not wish to have "auto commit mode" you just need to use a transaction object to manually control the transaction.
I'm just nervous at the idea of ODP.NET initiating interactions I am not aware of.I think it would be more fair to say "finishing interactions" in this case rather than "initiating interactions" but you could always just run a SQL trace from the database to see exactly what is happening if you are concerned.

Global Temp Tables

Has anyone had any luck using global temp tables within DI? I am tryng to create a process that will populate a global tmp table in one data flow and then read from that global tmp table in the next data flow within the same work flow. A template table won't work for my needs as I also need to be able to do a lookup_ext... is null from this table as well.
There is a risk in using a physical temp table as this process will be ran many times through out the day with various values.
Thanks,
Alicia

Within Oracle one can create a Global Temporary Table which is a database object; however, it clears it's contents when the session is released. It is useful when creating reusable routines as multiple processes can write different information to the table and the table maintains the information for the life of the SQL session. For instance one can populate the table with a list of codes to be used in a SQL statement for a product and run a seperate process simutaneously populating codes for a different product.
The probelm I am having right now is that DI seems to be closing it's SQL session before it goes to the Data Flow that needs the code list.
Thanks,
Alicia

Global Temp Tables in a Stored Proc

Hi All,
I'm trying to create a procedure that creates some tables and then creates global temporoay tables. This runs fine in a scrupt but when I place it in a proc, it fails with the following error
Error(172,10): PLS-00103: Encountered the symbol "TABLE" when expecting one of the following: := . ( @ % ;
I'm using the code below to create the global temp tables but I don't think you can do this in a procedure????
TRUNCATE TABLE TMP_table;
DROP TABLE TMP_table;
CREATE GLOBAL TEMPORARY TMP_table
ON COMMIT PRESERVE ROWS
AS SELECT
Thanks for any help given

Why are you trying to create a temporary table in a stored procedure?
In Oracle, you almost certainly want to create the temporary table once at compile time just like any other table. The difference is that the data in a temporary table is local to the session.
If you really wanted to execute DDL in a stored procedure, you'd need to use dynamic SQL. But it's almost always a bad idea to do so.
