Does Global Temporary Table help in performance?

I have a large database table that is growing daily. The application I have has a page for the past day data and another for some chosen period of time. Since I'm looking at a very large amount of data for each page (~100k rows) and having charts based on time, I have performance issues. I tried collections for each of these and found out that it is making everything slower and I think because the collection is large and it is not indexed.
Since I don't need the data to be maintained for the session and in fact for each time that I submit a page I need to get the updated data at least for the past day page, I wonder if Global Temporary Table is a good solution for me.
The only reason I want to store the data in a table is to avoid running similar queries for different charts and reports. Is this a valid reason at all?
If this is a good solution, can someone give me a hint on how to do this?
Any help is appreciated.

It all depends on how efficient your query is. You can have a billion row table and still get a fraction of a second response if the data is indexed, and the number of data blocks to be visited to retrieve the data is small. It's all about reducing the number of I/Os to find and retrieve your data with the query. Many aspects of the data, stats, table/index structure etc can influence the efficiency of your query. The SQL forum would be a better place to get into the query tuning, but if this test is fast, you can probably focus elsewhere for now. It will resolve your full resultset, and then just do a count of the result (to avoid sending 100k rows back to the client). We are trying to get an idea of how long it takes to resolve your resultset. Using litterals rather than item names in your sql should be fine for this test. Avoid using V() around item names in your SQL.
select count(*) from ( <your-query-goes-here> );

Use of global temporary tables in Procedures

Hi
I am using global temporary tables in the procedures. Loading data in the same table through many procedures. I am fetching the data from the global temporary table in PRO-C by a cursor. Will this degrade performance?
Please help me..
Thanks in Advance...

Will this degrade performance?That depends... in comparison to what?
Loading data into temporary tables will generally be more efficient than loading data into permanent tables because Oracle needs to do less to protect this data since it is inherently transient. On the other hand, loading the data into a table in the first place tends to be more expensive than alternatives like using a single SQL statement, a pipelined table function, or an in memory collection.

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.

What to fill in "temp table scope" for global temporary tables?

Hi,
I'm using Data Modeler 4.0.1.836 and whatever I put in the "temp table scope" box for a global temporary table doesn't seem to affect the DDL script regarding the ON COMMIT PRESERVE/DELETE ROWS option. The script always shows ON COMMIT PRESERVE ROWS no matter what.
Yet, some of my temporary tables must be created as ON COMMIT DELETE ROWS.
The Data Modeler help says the following about this :
Temp Table Scope:
For a table classified as Temporary, you can specify a scope, such as Session or Dimension.
Not sure what "Dimension" has to do with the scope here, but it doesn't make any difference.
I tried putting "Session", "Dimension", "Transaction", but no luck. So what's the text to put for the script to generate ON COMMIT DELETE ROWS?
Thanks

Hi,
The Temporary Table Scope property (on the Classification Types page of the Table Properties dialog) is purely documentary.
To set ON COMMIT DELETE ROWS you should expand the Browser node for the Relational Model and look for the node for the relevant Oracle Physical Model. If you expand this you will find an entry there for your Table. Double-click on this to get the Physical Model properties dialog for your table, and you will find a "Temporary" property which has options YES (Preserve Rows), YES (Delete Rows) or NO.

Hi there,
You have had quite a few replies from the previous post and you should have learnt from that.
Creating a procedure to do what you are trying to do is logically not sound.
Firstly, a Global temporary table IS a database object which continous to exist like a normal table except that its data is not permanent. Therefore, there is no point in creating it dynamically in a procedure.
Secondly, as I pointed out earlier, the data is temporary and it is gone once you issue a commit. A DDL like 'Create Table' will implicitly issue a commit after it has created the table - therefore all the data inserted as part of the Create Table statement will never be there.
Hence, the subsequent SELECT COUNT(*) from the table will always return 0.

John

A view is just a stored query. It can be on global temporary tables or regular one, makes no difference.

Using Global Temporary Table in OBIEE 11

Hi,
THe requirement is to run a database function before the report runs. This Function accepts 5 parameters (Presentation Variable) and populates a GTT Global Temporary Table.
This GTT is configured in presentation Layer.
Issue:
1. Created a dummy report which returns only one row and called the fucntion using "Evaluate" in this.
2. Created 2nd report using GTT Columns.
All these 2 reports placed on dashboard and Presentation variable are set in the prompt. The first one runs correctly and populate the "Regular Table". Means when I create a regular table instead of GTT I can see the correct record. But if I change it to GTT then the data does not get populated in this table.
Any Inputs?
Regards

HI,
If you are using a GTT, you need to run the function which populates the GTT before OBI server executes the select query on that table.
In your case, the OBI server is executing the select query from the table before the data is populated in the table.
In order to force the BI server to run the query after the GTT is populated, you need to specify the condition in the connection pool settings under the connection scripts tab.
In the execute before query, enter your physical query which runs the function to populate the GTT.
Hope this helps !
Thanks,
Vineeth

Global Temporary Table not deleting Rows

why is my Global temp table not deleting the rows after commit see below,

TBE VARCHAR2(7),
ABC VARCHAR2(8),
EFDA VARCHAR2(6),
ABD VARCHAR2(9),
A_ID VARCHAR2(128),
C_DATE,

Quite a few syntax issues with your create statement. It would have helped if you had posted a SQL*Plus session showing your results. Here is mine which works just fine:
sql>create global temporary table t_chg
2 (
3 tbe varchar2(7),
4 abc varchar2(8),
5 efda varchar2(6),
6 abd varchar2(9),
7 a_id varchar2(128),
8 c_date date
9 )
10 on commit delete rows;
Table created.
sql>insert into t_chg values ('1', '2', '3', '4', '5', sysdate);
1 row created.
sql>select count(*) from t_chg;
COUNT(*)
1
1 row selected.
sql>commit;
Commit complete.
sql>select count(*) from t_chg;
COUNT(*)
0
1 row selected.
