Global Users Table

Good afternoon,
I wasn't sure what to enter in the subject line, so as you see I used "Global Users Table". It doesn't completely convey what my question is, so I'll try to explain better.
We perform custom authentication in our Apex apps. Currently, we have a user table for each application that stores information about the user. It contains name, email address, password hash, roles, etc. It's a pretty nice process and works very well for us.
We want to migrate to a global user table and store all of our Apex users in 1 table. (We'll also have a separate table which will contain a row for each Apex app a person has access to and what their roles are.) This will have obvious advantages. For one we won't have to create a new app specific users table each time we create a new Apex app. And, we'll be able to use the same authentication procedure for all of our Apex apps since all users and their passwords will be in 1 table.
We haven't created any of the objects yet. We're just building the spec right now. Does anyone have experience in doing what we're attempting to do? If so, will you share how you accomplished it?
Thx, Tony

Sounds like an interesting idea.. Have you looked at the article from a few years back in Oracle magazine that showed how to code a portal type application that allowed access to individual applications, this handled the user information at that level, similar to what you are doing..
See this article from Oracle magazine June 2006: http://www.oracle.com/technetwork/issue-archive/2006/06-may/o36apex-086847.html

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!

Thanks!You may want to try changing your GTT to 'ON COMMIT DELETE ROWS' and have the .Net app use a transaction object.

GLOBAL TEMPORAY TABLE with the ability for a user to see others's entries

I have a list of record available for many user at the same time for them to work on.
Every one has the tendency to chosse the first record...
I want each of the users to be able to chose a different record once the preceding record has been selected by another user.
It would have been somthing like a GLOBAL TEMPORAY TABLE but with the ability for every user to see others records
so I would do and anti-join...
Does anyon have an idea on how I could implement such a behavior?

You will not be able to use a global temporary table for such a requirement.
It sounds like you will need a permanent table, which you will need to lock certain records (prohibiting users from taking those already in use), you can look at using the DBMS_LOCK package for this.
That's just speculation based on what you've typed, if you provide more details you make get more specific help.

Global temp table and edit

Hi all,
Can someone tell me why when I create a GTT and insert the data like the followijng ,I get insert 14 rows msg. But when I do a select statement from sqlwork shop , sometimes i get the data sometimes I don't. my understanding is this data is supposed to stay during my logon session then got cleaned out when I exit session.
I am developing a screen in apex and will use this temp table for user to do some editing work. Once ithe editing is done then I save the data into a static table. Can this be done ? So far my every attempt to update the temp table always result to 0 rows updated and the temp table reversed back to 0 rows. CAn you help me ?
CREATE GLOBAL TEMPORARY TABLE "EMP_SESSION"
(     "EMPNO" NUMBER NOT NULL ENABLE,

     "JOB" VARCHAR2(9),
     "MGR" NUMBER,
     "HIREDATE" DATE,
     "SAL" NUMBER,
     "COMM" NUMBER,
     "DEPTNO" NUMBER
) ON COMMIT PRESERVE ROWS
insert into emp_session( EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO)
select * from emp
select * from emp_session
-- sometimes I get 14 rows, sometimes 0 rows
Thanks.

Tai,
To say that Apex doesn't support GTT's is not quite correct. In order to understand why it is not working for you and how they may be of use in an Apex application, you have to understand the concept of a session in Apex as opposed to a conventional database session.
In a conventional database session, as when you are connected with sqlplus then you have what is known as a dedicated session, or a synchronous connection. Temporary objects such as GTTs and packaged variables can persist across calls to the database. A session in Apex however is asynchronous by nature and a connection to the database is done through some sort of a server such as the Oracle HTTP server or the Apex Listener, which in effect maintains a pool of connections to the database and calls by your application aren't guaranteed to get the same connection for each call.
To get over this, the guys who developed Apex came up with various methods to maintain session state and global objects that are persistent within the context of an Apex session. One of these is Apex collections, which are a device for maintaining collection like (array like) data that is persistent within an Apex session. These are Apex session specific objects in that they are local to the session that creates and maintains them.
With this knowledge, you can then see why the GTT is not working for you and also how a GTT may be of use in an Apex application, provided you don't expect the data to persist across a call, as in a PL/SQL procedure. You should note though, that unless you are dealing with very large datasets, then a regular Oracle collection is preferable.
I hope this explains your issue.

Global Temp table with BLOB causing session crash

Hi,
i have a table as follows:
create global temporary table spg_file_import (
name varchar2 (128) constraint sfi_nam_ck not null,
mime_type varchar2 (128),
doc_size number,
dad_charset varchar2 (128),
last_updated date,
content_type varchar2 (128),
content long raw,
blob_content blob
on commit delete rows
this is my 9ias 'document' table thats used to receive uploaded files which i modified to be global temporary.
what i want to do is:
a)upload a text file (xml)
b) convert that file to clob
c) store that file in new permanent table as clob
d) commit (hence delete temp table rows as they are no longer necessary)
to test it i have:
CREATE OR REPLACE procedure daz_html
as
begin
htp.p(' <FORM enctype="multipart/form-data" action="daz_fu" method="POST">');
htp.p(' <p>');
htp.p(' File to upload: <INPUT type="file" name="p_file_in"><br>');
htp.p(' <p><INPUT type="submit">');
htp.p(' </form>');
htp.p('</body>');
htp.p('</html>');
end;
CREATE OR REPLACE procedure daz_fu (
p_file_in varchar2
as
-- BLOB Stream locator
v_raw blob;
v_clob clob;
v_blob_length number;
v_length number;
v_buffer varchar2(32767);
v_pos number := 1;
begin
-- Get xml document from transient 9iAs data store.
select blob_content
into v_raw
from spg_file_import
where name = p_file_in;
-- create temp LOB
dbms_lob.createtemporary(v_clob, false);
-- get BLOB length
v_blob_length := dbms_lob.getlength(v_raw);
loop
-- get length to read. this is set as a max length of 32767
v_length := least((v_blob_length - (v_pos-1)),32767);
-- assign BLOB to a varchar2 buffer in preparation to convert to CLOB
v_buffer := utl_raw.cast_to_varchar2(dbms_lob.substr(v_raw, v_length, v_pos));
-- now write out to the CLOB
dbms_lob.writeappend(v_clob, v_length, v_buffer);
-- increment our position.
v_pos := v_pos + v_length;
-- exit when we are done.
exit when v_pos >= v_blob_length;
end loop;
commit;
htp.p('commit done!');
end;
now if i upload a small text file (about 5kb) it works with no problem.
however if I upload a large text file (say about 1Mb) it crashes oracle with:

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 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.

Life time of data in a Global Temporary Table.

Dear Friends,
I have a global temporary table in which I insert some values via a backend package, when forms start up and accessing it via the same package when user performs some changes in it - storing the value and during exit saving it in the master table. My problem is the data is not accessible while processing. I'm using Oracle9i Enterprise Edition Release 9.2.0.1.0 database and Forms [32 Bit] Version 6.0.8.8.0. I also give you the script in using which I created the temporary table.
CREATE GLOBAL TEMPORARY TABLE GTT_PRA
A1 VARCHAR2(10 BYTE) NOT NULL,
A2 VARCHAR2(15 BYTE) NOT NULL,
A3 VARCHAR2(10 BYTE) NOT NULL
ON COMMIT DELETE ROWS;
Why is that so? Please help me.
With Regards,
Senthil .A. Perumal.

Dear Arun,
Thank you for your script. But I'm accessing a large table, so for each and every process, the table get populated and grows very large giving some space problem, that is why I'm deleting rows when commiting. I would appreciate your help.
Dear Yogesh,
From the same forms I'm calling the backend package - will that be a different session. Once I'm calling to populate the table and next time I'm calling to store the user modified data and finally calling to store the data to master table. I think all are in the same sessions. Please reply me.
Thank you dear friends fr your immediate response. I would really appreciate it.
Regards,
Senthil .A. Perumal.

Hi,
"CREATE GLOBAL TEPORARY TABLE ..." is not a PL/SQL command; it is a SQL command only.
Create the table, using that statement, before running the PL/SQL block.
You can issue SQL statements from within PL/SQL using the EXECUTE IMMEDIATE command, but this is rarely a good idea.
I assume the PL/SQL code is meant to create the table and then populate it.
You should split those into two separate pieces of code. You'll only want to create the table once, no matter how many times you use it. I assume you'll want to populate it the same way many times. Remember, the "TEMPORARY" in "GLOBAL TEMPORARY TABLE" refers to the data, not the table. When you end a transaction (or a session, depending on whther you want "ON COMMIT DELETE ROWS" or "ON COMMIT PRESERVE ROWS"), the data disappears, but the now-empty stays, ready to be populated for the next transaction (or session).

Global Temporary table is Not working For Pdf Reports

Hi all
we are using oracle db-10g, developer suite-10g.
While generating the Report for the satisfying several conditions we are fetching the data into
Global temporary table
On commit preserve rows
from this temp tables excel is generated properly. but pdf is not generating can anybody exaplain why it is not generating and what to do for that
Thank you

query and view are not possible
here i am giving one of the requirement
my project is belongs to inventory project.
report should be generated on the different selection criteria like
1)user can select one or more product codes
2)for that product code one or more item codes can select
like this so many different selection are there more than 12 selections from different tables
For this each different selection product code into gtt_prod_cd and item_cd into gtt_item_cd. after that performed the query and in where clause we are comparing the values with gtt.
can you please suggest me what to do for PDF Reports

on commit preserve rows;So this should preserve the rows inserted into this table until the session ends.
Have a webpage in front-end where in turn, it opens another page (session is carried through) and a few rows will be inserted to this table from the webpage (through a function) on submit and the current page will be closed.
From the parent page, if I open the sub-page data inserted in the temporary table are held and displayed (another function to fetch the values in the Global Temp table).
The Problem in Oracle 10g (Production) is, this is not happening properly. When I close and open the sub-page, not every time I get the data stored i.e if I close and open the page 10 times, atelast 4 times the data is missed in the page (I am not getting values from temp table) randomly.
But this does not happen in UAT (which has Oracle 11g installed) as I get the data in the webpage consistently. After passing UAT, when we rolled out to Prod, getting this issue which we are unable to get what could be the reason.
It is very hard to debug using GTT dynamically in prod. It takes time to get Oracle 11g installed in Prod.
Can anyone suggest?

Also, I am opening the sub-page from the parent page (through a hyperlink). Then in this case, Would session will be changed from parent to subpage? (I am not aware exactly and have the impression that, as the second page is a child, I guess it would take the same session).I'm not sure what "sub-page" or "parent page" means to you. If you're just linking from one page to another, "parent" and "child" don't really make sense since page A links to page B and B links to A quite frequently.
Assuming that you have to log in to access the site, it is likely that the two pages share the same middle tier application session. It is unlikely that the middle tier would hold the database session from the first request open waiting to see if the user eventually requested the second page. It is theoretically possible that you could code your middle tier this way but it is extremely unlikely that you would want to do so for a variety of reasons. So, when you say "would [the] session ... be changed", it is likely that the application session would be the same for both calls but that the database session would be different.

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.

Global temporary table in a store procedure

Hi,
I REALLY need to create a global temporary table in a stored procedure but I don't know how .........
My solution was
create or replace procedure test(
as
begin
execute immediate 'create global temporary table t(x number,..) ;';
end;
but the table is not created. What I am doing wrong and how to resolve the problem?
Thanks.

There is NO valid reason to create a GTT on the fly (except during installation of a package). This defeats the entire logic behind it. Precreate it and use it by a million users at the same time and it won't care. For more information On GTT's see.
