Analyze Table required on a Global Temp. Table

Hi,
This is the background. We have a Windows reporting Oracle Server where we write stored procedures to access data mainly based off a warehouse residing on a unix box. DBLinks have been setup and synonym's created .
We create Global Temp. Tables to store temp. data used by our report stored procedures. I have one query that accesses 5 remote tables and one local table
The query was taking hours to run...after some research i found out that when I did an "Analyze Table" on my Global temp. table, the query came back in a few minutes.
My confusion is that this table being a GTT.. it will always be empty when we run "Analyze Table" on it. What information is oracle? Do we need to run "analyze table" on all our GTT's created for different reports?
Second question on show query plan
Also if I do a query plan on this query ORacle dooes not provide a plan on the remote tables. If i change the query by removing the reference to the local table and hardcoing some vlaues, oralce returns a query plan for the query which now only uses the remote tables. Is this correct?

Hi,
you can fake the statistics of the temporary table.
First create a real table (with indexes) that looks like the temporary table. Load the table with representative data.
Then
dbms_stats.gather_table_stats(ownname=>'schemauser',tabname=>'TEMPCOPY');
dbms_stats.create_stat_table(ownname=>'schemauser',stattab=>'TEMPSTATS');
dbms_stats.export_table_stats(ownname=>'schemauser',tabname=>'TEMPCOPY',stattab=>'TEMPSTATS'); --do that for every index
dbms_stats.export_index_stats(ownname=>'schemauser',indname=>'INDEXNAME',stattab=>'TEMPSTATS');Now we import the generated statistics:
dbms_stats.import_table_stats(ownname=>'schemauser',tabname=>'TEMPTABLE',stattab=>'TEMPSTATS');
dbms_stats.import_index_stats(ownname=>'schemauser',tabname=>'TEMPTABLE',stattab=>'TEMPSTATS'); --for every indexOf course you can create a set of statistics and load them as needed.
Dim
dbms_stats.

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 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.

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;

select blob_content
into v_raw
from spg_file_import

-- 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.

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.

A better way than a global temp table to reuse a distinct select?

I get the impression from other threads that global temp tables are frowned upon so I'm wondering if there is a better way to simplify what I need to do. I have some values scattered about a table with a relatively large number of records. I need to distinct them out and delete from 21 other tables where those values also occur. The values have a really low cardinality to the number of rows. Out of 500K+ rows there might be a dozen distinct values.
I thought that rather than 21 cases of:
DELETE FROM x1..21 WHERE value IN (SELECT DISTINCT value FROM Y)
It would be better for performance to populate a global temp table with the distinct first:
INSERT INTO gtt SELECT DISTINCT value FROM Y
DELETE FROM x1..21 WHERE value IN (SELECT value FROM GTT)
People asking questions about GTT's seem to get blasted so is this another case where there's a better way to do this? Should I just have the system bite the bullet on the DISTINCT 21 times? The big table truncates and reloads and needs to do so quickly so I was hoping not to have to index it and meddle with disable/rebuild index but if that's better than a temp table, I'll have to make do.
As far as I understand WITH ... USING can't be used to delete from multiple tables or can it?

Almost, but not quite, as efficient as using a temporary table would be to use a PL/SQL collection and FORALL statements and/or referencing the collection in your subsequent statements). Something like
DECLARE
TYPE value_nt IS TABLE OF y.value%type;
l_values value_nt;
BEGIN
SELECT distinct value
    BULK COLLECT INTO l_values
    FROM y;
FORALL i IN 1 .. l_values.count
    DELETE FROM x1
     WHERE value = l_values(i);
FORALL i IN 1 .. l_values.count
    DELETE FROM x2
     WHERE value = l_values(i);
END;or
CREATE TYPE value_nt
IS TABLE OF varchar2(100); -- Guessing at the type of y.value
DECLARE
l_values value_nt;
BEGIN
SELECT distinct value
    BULK COLLECT INTO l_values
    FROM y;
DELETE FROM x1
   WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
DELETE FROM x2
   WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
END;Justin

Error while creating Global temp table

Hi,
I am very new to PL/SQL so please excuse my question. I have the below query . I have to get a count between the source table and various target tables. I am creating a global temp table to store the counts. I am getting the below error for my following query :
Thanks for the help,
Petronas
----Query----
set serveroutput on
Declare
nm1 varchar2(200);
nm2 varchar2(200);
cnt1 number;
cnt2 number;
diff number;
totdiff number;
Begin
nm1 := null;
nm2:= null;
cnt1:= 0;
cnt2 := 0;
diff := 0;
totdiff := 0;
create GLOBAL TEMPORARY TABLE diff ( name1 varchar(200), name2 varchar2(200), diff number);
select count(*) into cnt1
from users_staging;
select count(*) into cnt2
from PROD.users;
nm1 := 'users_staging';
nm2 := 'PROD.users';
diff := cnt1 - cnt2;
insert into diff values (nm1,nm2,diff);
select count(*) into totdiff
from diff
where diff> 0 ;
dbms_output.enable(10000);
dbms_output.put_line('# of tables where difference is > 0 ' ||totdiff);
end;
Encountered the symbol "CREATE" when expecting one of the following:
begin case declare end exception exit for goto if loop mod
null pragma raise return select update while with
<an identifier> <a double-quoted delimited-identifier>
<a bind variable> << close current delete fetch lock insert
open rollback savepoint set sql execute commit forall merge
pipe

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 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!
