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)

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?
ThanksThe 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.

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 AMi 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? -
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 ?

TaiTai,
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.

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!
AnandAssuming 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 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.Hi there...

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...

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.

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 );

pipeHi,
"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! -

Update Global Temp Table in Oracle 11g
Hi Experts,
Scenario: I have stored procedure A which calls procedure B. Procedure B uses Global temp Tables(With On Commit Preserve Rows) to work with the data.
I am trying to update one of the GTT in Proc B but unable to do it .. via SQL or via PL/SQL Cursor/Collection. There is no syntax nor logical error and the PL/SQL proc completes execution successfully but the rows are not getting updated. My Db version is Oralce 11g 11203.
Update statement is something like this.
Update <GTT>
SET amount1 = amount1 *-1, amount2 = amount2 *-1
where field1 = <value>
and field2 in ( Select filed2 from <table1> );
Any idea why would this update not work? Has anyone faced this issue in Oracle 11g??
Appreciate your suggestions & thanks in Advance for your inputs.
Cheers,
MSUpdate statement is something like this.
Update <GTT>
SET amount1 = amount1 *-1, amount2 = amount2 *-1
where field1 = <value>
and field2 in ( Select filed2 from <table1> );
Any idea why would this update not work?
You already told us that it DOES work - no errors or exceptions.
It is trivial to determine if that update will do anything - just turn it into a SELECT and see if any rows are ntselected:
v_cnt INTEGER;
SELECT COUNT(*) INTO v_cnt FROM myGTT
WHERE field1 = <value>
AND field2 in (Select field2 from <tablee1>);
Then take a look at the 'count' that you get. -
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.
