Global temp table vs. package variables

hi all,
i need to know which is a better approach to store session based values in terms of security and performance.
option one
create global temporary table my_session_tbl ( code varchar2(30), value varchar2(1000) );option two
create or replace package my_session
as
type session_tab_type is table of varchar2(1000) index by varchar2(30);
session_tab session_tab_type;
end;thanks
allen

That depends entirely on your requirements.
For example, if you are using that temp values primarily in SQL, storing it in PL requires (expensive) context switching from SQL to PL to access the values. If the temp values are primarily used in PL code, the reverse is true.
PL code requires PGA memory - private and expensive process memory. So there is a limit on just how much temporary values you can pump into a PL data segment before it becomes very expensive.
It depends on how you want to use that temp values. A GTT supports indexing, and via SQL can be filtered, sorted, aggregated, and analysed far easier that any data structure in PL code.
So you need to look at:
a) how you are going to use the data
b) from what language
c) what the data volumes are
I fail to see how security will play an issue - as a GTT and PL data structure are both local to the current process. Exposing that would in both cases be a coding flaw and not a problem or issue associated with the GTT or PL data structure itself.

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 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!

Global temp tables for GeoRaster mosaicing

Hi,
Although this question involves the GeoRaster capability contained in the Spatial package, it has more to do with global temp tables, so it's in this forum group.
The mosaicing function requires all the individual images (there is an image in each record) to be in their own table before they can be mosaiced, as there is no way to stipulate only certain images in a table should be used.
So the best idea I've had so far is to use a global temp table where the images I need can be selected and put in the temp table - then mosaiced. It is important that the temp table contain only the images needed for a given mosaic. However, I will be doing the mosaic operation many times in a given session (possibly even more than 1 mosaic at the same time) and am worried that there will be old or unrelated records in the temp table.
Does this mean I have to make a new session every time I need to mosaic an image? This doesn't sound very efficient. Can I have just one session but have a "new" temp table each time?
Thanks,
MH

I have very limited experience with Spatial, and have never done anything like a mosaic
But regarding Global Temp... If you want to make sure the GTT is empty every time, just end your transaction (commit or rollback). This will remove all data from the GTT (if you had it made with ON COMMIT DELETE ROWS - the default)

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.

Inserting data in global temp table?

Hello experts,
i have a form having base table master and detail. i can insert upadate the records.
requirement: creating the global temp table for same form. sothat data save only form session.
for this i created 2 global temp table having same structure required for same form.
i changes the property for block as base table to global temp table.
now i am trying to save the records but not going in the temp table. as i changes the block base table property to temp tables
as well as advance data block properties also .
please tell me the reason? where can be the problem.
thanks yash
Edited by: yash_08031983 on Apr 16, 2012 1:27 AM

i am trying to save the records but not going in the temp table.How do you check that? You cannot go to sqlplus and check if there are any records in the GTT. Data in a GTT is only visible in the current session (= only in the form).
What is the use of a GTT here? What are you trying to achieve?

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.

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.

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).

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.

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.

REPORT ON GLOBAL TEMP TABLE

I EXTRACT DATA FOR MY REPORT FROM A GLOBAL TEMP TABLE ( ON COMMIT PRESERVE ROWS).
BUT WHEN I RUN REPORT I GET NO DATA DISPLAYED ON MY REPORT...
WHAT MIGHT BE WRONG ?
((REPORT VERSION 10G))

Hello,
The problem is is that CR does not have permissions to read the temp table because there is no API that allows you to connect using an existing connection. There was an older API that allowed you to connect using the ODBC HDBC handle but in CR 2008 and .NET that API has been deprecated.
You'll have to code as you suggest using publicly available temp tables. Or you may want to use Record Sets. As long as the number of rows is less than 100k this should work for you.
Search here as well as sample app's on how to and which DB driver to use.
Thank you
