Temp Tables conversion

Hi
Can anyone help me with the exact syntax to create temp table in
Oracle 8i in Stored Proc. Eg.
CREATE PROCEDURE MROSiteNoVendors
@IDCustomer INT
AS
SELECT DISTINCT s.IDCustomer, SiteName, Address , AddressII,
City, State, Zip, s.IDSite
INTO #TempTbl
FROM Sites s LEFT JOIN rSiteVendors rSV ON s.IDSite =
rSV.IDSite
WHERE (s.IDCustomer = @IDCustomer)
ORDER BY SiteName
Update #TempTbl Set Address = '' WHERE Address Is Null
Update #TempTbl Set City = '' WHERE City Is Null
Update #TempTbl Set State = '' WHERE State Is Null
Update #TempTbl Set Zip = '' WHERE Zip Is Null
SELECT * FROM #TempTbl
DROP TABLE #TempTbl
null

Best options to use in Temp Table

Hello,
I was just trying to figure out the best options we can choose with when we come across a scenario where we need to use a Temp Table/Table Variable/Create
a Temp Table on the fly.
However, I could not see any big difference in using those options. As per my understanding using a table variable is more convenient if the query logic is
small and the result set also will be comparatively small.Creating a temp table is also an easy option but it takes much time and we can not create any indexes on it. I am working on a query optimization task where in plenty of temp tables are used
and the query takes more than five minutes to execute. We have created few indexes and all in few tables and reduced the query execution time up to 2 mnts.Can anyone give me more suggestions on it. I have gone through various articles about it and came to
know that there is no one solution for this and I am aware of the basic criteria like use Set No count on, Order the table in which the indexes are created, Do not use Select * instead use only columns which are really required, Create Indexes
and all. Other than these I am stuck with the usage of temp tables. There are some limitations where I can convert all the Temp table logic to CTE (I am not saying its not possible, I really dont have time to spend for the conversion). Any suggestions are
welcome.

Actually, we want to avoid all of those things in a declarative/functional language. The goal is to write the solution in a single statement. What you are doing is mimicking a scratch tape in a 1950's tape file system.
Another non-declarative technique is to use UDFs, to mimic 1950's procedural code or OO style methods. Your sample code is full of COBOL-isms! In RDBMS we follow ISO-11179 rules, so we have “<something in particular>_code” rather than just “code” like
a field within a COBOL record. The hierarchical record structure provides context, but in RDBMS, data elements are global. Or better, they are universal names.
>> I am aware of the basic criteria like use SET NO COUNT ON, Order the table in which the indexes are created, Do not use SELECT * instead use only columns which are really required, CREATE INDEXes and all.<<
All good, but you missed others. Never use the same name for a data element (scalars) and a table (sets). Think about what things like “ProductionResponse.production_response” means. A set with one element is a bit weird, but that is what you said. Also, what
is this response? A code? A count? It lacks what we call an attribute property.
This was one of the flaws we inherited when ANSI standardized SQL and we should have fixed it. Oh well, too late now.
Never use NVARCHAR(MAX). Why do you need to put all of the Soto Zen sutras in Chinese Unicode? When you use over-sized data elements, you eventually get garbage data.

Yes! This is how we do declarative/functional programming! Make the effort, so the optimizer can work, so you can use parallelism and so you can port your code out of T-SQL dialect.

Data storage in temp tables

Question 1: I have created a global temporary table tt_groups(grp_ids number) on commit preserve rows; and I was wondering - if I have multiple users accessing this temp table at the same time, do I need to differenciate between the users, or will Oracle put a userid on them?
Question 2: I am attempting to enter data into these temp tables within a function that will actually use the data. This function contains and returns a cursor. So far, I have been having great difficulties with this - to the point that I am ready to write an addition function just to store the data in the temp table. Does any one have any suggestions? Here is a sample of my code in case that would help. btw - str2tbl is a home grown conversion tool that parses a string and puts the data into rows of number. We have used it in many functions and so far don't have any issues associated with it.
in_groupid IN VARCHAR2
IS
BEGIN
INSERT INTO tt_groups(grp_ids)
VALUES (
SELECT Column_Value
FROM THE (
select cast(STR2TBL(in_groupid) as mytableType)
from dual
COMMIT;
END;
I am new to the whole sp/function coding, so any advice would be appreciated.
Thanks,
Susan

Thanks, Justin, for your reply.
I am pleased to hear that the temp table is session-specific.
I attempted to update my statement to match what you suggested, but I am still getting "invalid" whenever I try to compile the function through schema mgr. Do you see anything that I might be missing? I incorporated the BEGIN; COMMIT; and END;, but is there something else that I am supposed to have? I downloaded a couple of Oracle handbooks and I have one book, Oracle8i - the complete reference, (we are using 9i) that I am referring to all the time, but I can't seem to get it to work! Here is more of my code:
in_groupid IN VARCHAR2
RETURN Types.ref_cursor
AS
resource_cursor types.ref_cursor;
BEGIN
OPEN resource_cursor FOR
SELECT DISTINCT
CATEGORY.CATID, SUBCATEGORY.SUBCATID
FROM SUBCATEGORY, CATSUBCAT, CATEGORY, SUBRES
WHERE SUBCATEGORY.SUBCATID = CATSUBCAT.SUBCATID AND
CATSUBCAT.CATID = CATEGORY.CATID AND
(CATSUBCAT.GROUPID IN (select grp_ids from tt_groups)) AND
(SUBRES.GROUPID IN (select grp_ids from tt_groups))
I want to insert this code into the function above:
INSERT INTO dtra_tt_groups(grp_ids)
SELECT Column_Value
FROM THE (
select cast(STR2TBL(in_groupid) as mytableType)
from dual
COMMIT;
Where would I insert this statement?
Thanks,
Susan

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!

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"

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 (

-- 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));

If i reaplce the temporary table with a non-temp table of the same structure i get no problems what-so-ever. Am I doing something that I shouldnt be with global temporary tables?
Thanks.

This is on Oracle 8.1.7.2

Global Temp Table, always return zero records

I call the procedure which uses glbal temp Table, after executing the Proc which populates the Global temp table, i then run select query retrieve the result, but it alway return zero record. I am using transaction in order to avoid deletion of records in global temp table.
whereas if i do the same thing in SQL navigator, it works
Cn.ConnectionString = Constr
Cn.Open()
If FGC Is Nothing Then
Multiple = True
'Search by desc
'packaging.pkg_msds.processavfg(null, ActiveInActive, BrandCode, Desc, Itemtype)
SQL = "BEGIN packaging.pkg_msds.processavfg(null,'" & _
ActiveInActive & "','" & _
BrandCode & "','" & _
Desc & "','" & _
Itemtype & "'); end;"
'Here it will return multiple FGC
'need to combine them
Else
'search by FGC
SQL = "BEGIN packaging.pkg_msds.processavfg('" & FGC & "','" & _

'will alway return one FGC

Hi,
This forum is for Oracle's Data Provider and you're using Microsoft's, but I was curious so I went ahead and tried it. It works fine for me. Here's the complete code I used, could you point out what are you doing differently?
Cheers,
Greg
create global temporary table abc_tab(col1 varchar2(10));
create or replace procedure ins_abc_tab(v1 varchar2) as
begin
insert into abc_tab values(v1);
end;
using System;
using System.Data;
using System.Data.OracleClient;
class Program
    static void Main(string[] args)
        OracleConnection con = new OracleConnection("data source=orcl;user id=scott;password=tiger");
        con.Open();
        OracleTransaction txn = con.BeginTransaction();
        OracleCommand cmd = new OracleCommand("begin ins_abc_tab('foo');end;", con);
        cmd.Transaction = txn;
        cmd.ExecuteNonQuery();
        cmd.CommandText = "select * from abc_tab";
        OracleDataAdapter da = new OracleDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds);
        Console.WriteLine("rows found: {0}", ds.Tables[0].Rows.Count);
        // commit, cleanup, etc ommitted for clarity
