Temp Table

Hi All
Hi to use Global temp tables in Oracle?
-Regards
Mani

Step 1: Create a table as indicated in the documentation. Your only tricky decision here is whether to keep the data for the duration of the transaction or the session.
Step 2: Insert data into the table.
Step 3: Select data from the table.
Safe when used as directed.

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.

Temp Tables - Best Practice

Hello,
I have a customer who uses temp tables all over their application.
This customer is a novice and the app has its roots in VB6. We are converting it to .net
I would really like to know the best practice for using temp tables.
I have seen code like this in the app.
CR2.Database.Tables.Item(1).Location = "tempdb.dbo.[##Scott_xwPaySheetDtlForN]"
That seems to work, though i do not know why the full tempdb.dbo.[## is required.
However, when i use this in the new report I am doing I get runtime errors.
i also tried this
CR2.Database.Tables.Item(1).Location = "##Scott_xwPaySheetDtlForN"
I did not get errors, but I was returned data i did not expect.
Before i delve into different ways to do this, i could use some help with a good pattern to use.
thanks

Hi Scott,
Are you using the RDC still? It's not clear but looks like it.
We had an API that could piggy back the HDBC handle in the RDC ( craxdrt.dll ) but that API is no longer available in .NET. Also, the RDC is not supported in .NET since .NET uses the framework and RDC is COM.
Work around is to copy the temp data into a data set and then set location to the data set. There is no way that I know of to get to the tempdb from .NET. Reason being is there is no CR API to set the owner of the table to the user, MS SQL Server locks the tempdb to that user has exclusinve rights on it.
Thank you
Don

Difference between Temp table and Variable table and which one is better performance wise?

Hello,
Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
Which one is recommended to use for better performance?
also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
Is that Table variable using Memory or Disk space?
Thanks Shiven:) If Answer is Helpful, Please Vote

Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
But it also depends upon specific scenarios you are dealing with , can you share it?

Benefit and limitation of temp table in sql server 2008

I have a datagrid in front end of asp.net . when user select a row it shows another gridview (multiple row ) where user have to put some data. when user click CLOSE button i have to keep all data of 2nd gridview in reference with 1st gridview row id.
Same process for each row of 1st gridview. If i will keep all the record in a datatable in view state and finally save the data in database table when final save is clicked then the process may be very slow due to large data in view state. So i think to store
data in temp datable in database for each CLOSE click. For this porpose which temp table i should use
1. Local temporary tables
2. Global temporary tables
3. Normal tables.
Multiple user may do the same thing same time. Please help me.
Thanks

>1. Local temporary tables
>2. Global temporary tables
>3. Normal tables.
When used in stored procedures, local temporary tables (#table) are automatically multi-user.
For global temp (##table) & normal tables, you need to develop your own mult-user logic.

Table or Object type - like #temp table in SQL Server

Hi
I need to create a temp table to hold certain data and then validate. What is the best way to do this oracle. Something similar to #temp tables in SQL Server.
Thanks

IN Oracle, you create the temporary table once, before you start your program. Then anyone can use that definition, but the system keeps the data isolated to eachr/session.
The difference in using Oracle: all DDL, including creating temp tables, performs commits and aquires locks that you want to avoid. It creates unnecessary serialization, causes transactional consistency issues and puts Oracle's Read Consistent model at risk (of ORA-01555 errors).
So, you (or the DBA) would "CREATE GLOBAL TEMPORARY TABLE ..." with the appropriate definition you want, and indicate whether you want the data deleted on commit, or on logoff.
Then you write your procedure, similar to the way you would do it in SQL Server, but you would not bracket it with creating/dropping the temp table - no need.

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?

How to read the data file and write into the same file without a temp table

Hi,
I have a requirement as below:
We are running lockbox process for several business, but for a few businesses we have requirement where in we receive a flat file in different format other than how the transmission format is defined.
This is a 10.7 to 11.10 migration. In 10.7 the users are using a custom table into which they are first loading the raw data and writing a pl/sql validation on that and loading it into a new flat file and then running the lockbox process.
But in 11.10 we want to restrict using temp table how can we achieve this.
Can we read the file first and then do validations accordingly and then write to the same file and process the lockbox.
Any inputs are highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.

Hello Gurus,
Let me tell you about my requirement clearly with an example.
Problem:
i am receiving a dat file from bank in below format
105A371273020563007 07030415509174REF3178503 001367423860020015E129045
in this detail 1 record starting from 38th character to next 15 characters is merchant reference number
REF3178503 --- REF denotes it as Sales Order
ACC denotes it as Customer No
INV denotes it as Transaction Number
based on this 15 characters......my validation comes.
If i see REF i need to pick that complete record and then fill that record with the SO details as per my system and then submit the file for lockbox processing.
In 10.7 they created a temporary table into which they are loading the data using a control file....once the data is loaded into the temporary table then they are doing a validation and updating the record exactly as required and then creating one another file and then submitting the file for lockbox processing.
Where as in 11.10 they want to bypass these temporary tables and writing it into a different file.
Can this be handled by writing a pl/sql procedure ??
My findings:
May be i am wrong.......but i think .......if we first get the data into ar_payments_interface_all table and then do the validations and then complete the lockbox process may help.
Any suggestions from Oracle GURUS is highly appreciated.
Thanks & Regards,
Lakshmi Kalyan Vara Prasad.

Global Temp Table or Permanent Temp Tables

I have been doing research for a few weeks and trying to comfirm theories with bench tests concerning which is more performant... GTTs or permanent temp tables. I was curious as to what others felt on this topic.
I used FOR loops to test out the performance on inserting and at times with high number of rows the permanent temp table seemed to be much faster than the GTTs; contrary to many white papers and case studies that have read that GTTs are much faster.
All I did was FOR loops which iterated INSERT/VALUES up to 10 million records. And for 10 mil records, the permanent temp table was over 500k milliseconds faster...
Anyone have an useful tips or info that can help me determine which will be best in certain cases? The tables will be used for staging for ETL Batch processing into a Data Warehouse. Rows within my fact and detail tables can reach to the millions before being moved to archives. Thanks so much in advance.
-Tim

> Do you have any specific experiences you would like to share?
I use both - GTTs and plain normal tables. The problem dictates the tools. :-)
I do have an exception though that does not use GTTs and still support "restartability".
I need to to continuously roll up (aggregate) data. Raw data collected for an hour gets aggregated into an hourly partition. Hourly partitions gets rolled up into a daily partition. Several billion rows are processed like this monthly.
The eventual method I've implemented is a cross between materialised views and GTTs. Instead of dropping or truncating the source partition and running an insert to repopulate it with the latest aggregated data, I wrote an API that allows you to give it the name of the destination table, the name of the partition to "refresh", and a SQL (that does the aggregation - kind of like the select part of a MV).
It creates a brand new staging table using a CTAS, inspects the partitioned table, slaps the same indexes on the staging table, and then performs a partition exchange to replace the stale contents of the partition with that of the freshly build staging table.
No expensive delete. No truncate that results in an empty and query-useless partition for several minutes while the data is refreshed.
And any number of these partition refreshes can run in parallel.
Why not use a GTT? Because they cannot be used in a partition exchange. And the cost of writing data into a GTT has to be weighed against the cost of using that data by writing it (or some of it) into permanent tables. Ideally one wants to plough through a data set once.
Oracle has a fairly rich feature set - and these can be employed in all kinds of ways to get the job done.

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"

) 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.

Andre

Global Temp table Vs Regular table

Hi,
I need a temp table to store few IDs (which I select from a complex query). I would be deleting the data from the temp table at the end of the session.
From a performance perspective, I was wondering if I should be using a GLOBAL temporary table or just a regular table in which I will manually delete rows at the end.
The tkprof showed using the global temp table expensive. If yes, I just want to confirm it and know why it is the case.
Thanks!
Anand

Assuming that the cursor you open to get the transaction_id actually has a where clause, and refraining from comment on the need for dynamic column lists, I would likely do it something like:
DECLARE
   lv_query   VARCHAR2 (32767);
   l_col_list VARCHAR2(4000);
BEGIN
   l_col_list := control_module_common_pkg.get_columns('EPOS_TRANSACTION_HEADER',
                                                       FALSE);
   lv_query := 'INSERT INTO AK_TRANSACTION_HEADER ('||l_col_list||
               ' ) SELECT '||l_col_list||' FROM EPOS_TRANSACTION_HEADER
               WHERE ETH_TRANSACTION_ID IN (SELECT eth_transaction_id
                                            FROM epos_transaction_header
                                            WHERE <whatever would be in the cursor>)';
   EXECUTE IMMEDIATE lv_query;
   COMMIT;
END;If there really is no where clause ion the cursor, then it would simply be:
DECLARE
   lv_query   VARCHAR2 (32767);
   l_col_list VARCHAR2(4000);
BEGIN
   l_col_list := control_module_common_pkg.get_columns('EPOS_TRANSACTION_HEADER',
                                                       FALSE);
   lv_query := 'INSERT INTO AK_TRANSACTION_HEADER ('||l_col_list||
               ' ) SELECT '||l_col_list||' FROM EPOS_TRANSACTION_HEADER';
   EXECUTE IMMEDIATE lv_query;
   COMMIT;
END;In either case, I would also re-consider the commit in the procedure. It should perhaps be the caller of this procedure that issues the commit, not the procedure itself.

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.

Why don't you use permanent table in tempdb?

Global temp table trigger error on Oracle AS

we have a set of triggers that load a temp table in the before delete,update and process the table in an after statement trigger. the data that's loaded is a complaintid and when the complaintid is selected into a variable in the after statement, a No data found error is fired. This only happens on Oracle AS both 9i and 10g, it does not happen on jboss. All the app servers use connection pooling and they are 9i Enterprise Edition Dedicated database servers.
Is it possible that there is a bug in Oracle AS that allows multiple sessions to affect the same global variables ?
Sorry it's a long one, but I wanted to include everything I could
table creation script.

CREATE GLOBAL TEMPORARY TABLE test_glb ON COMMIT DELETE ROWS
AS SELECT * FROM test1;btw I'm assuming you are just using the SELECT statement to copy the definition of test1. Since DDL statements commit, there will be no rows in test_glb after creating it.
