How to purge data in a global temporary table from another session

I've got a problem with vendor-delivered web-based software (jdbc) that periodically "hangs." When that happens, I have to kill the database session before retrying the process. This "workaround" does NOT clean up the temporary tablespace. Is there anyway (outside of bouncing the database) to truncate temporary tables regardless of sessionid? Thanks.

In 8i the space used by temporary segments is not dropped in a temporary tablespace. The space is available for other queries or temporary tables. This avoids the costs of allocating and releasing space for temporary segments.

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.

Clearing out global temporary tables in a session.

I have a global temporary table that is used within one stored procedure. Another procedure calls it twice in succession and the second time the child SP is called, the temp table is retaining the values from the first call. I want to clear the contents of the temp table before the child SP completes, but am getting an "invalid table name" error when I try to truncate it or delete the contents. Any thoughts?
By the way, when I created the global temp table, I used 'on commit delete rows'
Thanks
Matt

How to get data of reti or reto table from payresult for retroactive

Hi all,
is there any of you have an experience in retrieving data for RETO or RETI (payroll retroactive accounting inflow) table in payresult?.
It is usually retrieved using pc_payresult t-code by the functional guy. RETO or RETI appears where there is a correction in the employee's wage. for instance, in January, the employee's wage is $3000 and he got a promotion so that he get $4000 monthly. but the payroll has already been posted, and the $3000 has already been transfered to his account. So that the salary raise ($1000) will be added in February and he will receive $5000 ($1000 + $4000) in February and $4000 in the next months. Using pc_payresult, in January, there will be created a RETO table which contain $1000 while in February there will also be created a RETI table which contain $1000.
In the ABAP HR code I am using PYXX_READ_PAYROLL_RESULT function mdule, but I didnt manage to find the table (RETO or RETI). If you guys have solutions regarding my problem, please have them shared with me.
Thanks before,
Irsyad

Hi Peter,
The FM HRCM_PAYROLL_RESULTS_GET works well but it still cannot show me the RETO and RETI table.
The RT table you mentioned above with betrg field is the total take home pay, which I already knew hot to get it.
My problem is when using tcode pc_payresult, if I click on each of the records I will get several tables such as:
WPBP
RT
RT_
CRT
BT
VERSION
PCL2
VERSC
TAX
INS
RETO
TAXCU
MODIF
Please notice the RETO table.
but when I use several FM, it only get me RT, WPBP, BT, CRT,... but not RETO table.
I need this RETO table because I want to get the data in it.
Do you know how to get the RETO table?
Thanks,
Irsyad

Are global temporary tables in Oracle 10.2 behaving differently?

My procedure is creating and inserting data into a Global Temporary Table (on commit data is preserved). I am running this procedure in two different environments.
The first environment is running under Oracle 10.2 and after the procedure runs successfully I can not see any data inserted in the GTT.
When I run the very same procedure in the second environment which runs under Oracle 9.2, it works fine, runs successfully and I can see all rows inserted in the GTT.
Can someone explain this? What should I do differently in the Oracle 10.2? Any thoughts?
Thank you very much.

Hi,
The following TEMPORARY table is created with the attribute, ON COMMIT DELETE ROWS. This allows an application to load registration entries into the global temporary table and manipulate that data with SQL statements. The data is deleted upon each commit with the clause ON COMMIT DELETE ROWS.
CREATE GLOBAL TEMPORARY TABLE student_reg_entries
student_name VARCHAR2(30),
reg_entries reg_entry_varray_type
) ON COMMIT DELETE ROWS;
Replace ON COMMIT DELETE ROWS with ON COMMIT PRESERVE ROWS to retain temporary table data throughout the database session, regardless of any commits made during that session.
The following illustrates a PL/SQL block that populates this temporary table with two classes each for two students. It makes no difference how many other applications are currently using this temporary global table for similar purposes. For the code below, two rows are inserted, then a COMMIT, after which a SELECT shows that the table is empty.
DECLARE
classes_to_take reg_entry_varray_type :=
reg_entry_varray_type();
BEGIN
classes_to_take := reg_entry_varray_type(
reg_entry('CS101', 'C' ),
reg_entry('HST310', 'C' ));
INSERT INTO student_reg_entries VALUES
('John', classes_to_take);
classes_to_take := reg_entry_varray_type(
reg_entry('ENG102', 'C' ),
reg_entry('BIO201', 'C' ));
INSERT INTO student_reg_entries VALUES
('Mary', classes_to_take);
END;
This next SELECT returns two rows:
SQL> SELECT * FROM student_reg_entries;
Row 1:
John
REG_ENTRY_VARRAY_TYPE
(REG_ENTRY('CS101','C'), REG_ENTRY('HST310','C'))
Row 2:
Mary
REG_ENTRY_VARRAY_TYPE
(REG_ENTRY('ENG102','C'), REG_ENTRY('BIO201','C'))
A COMMIT automatically deletes rows making the table available for the next session transaction.
SQL> COMMIT;
SQL> SELECT * from student_reg_entries;
no rows selected

Creating a Global Temporary Table on non-default TEMP tablespace.

Hello ,
I am using Oracle 11g.
I have a procedure which create global temporary tables for its functionality. As the data which is going in the global temporary table , mean the data which is going in the default TEMP tablesapce is too huge ..... billions of rows..
So what i want to do is , I want to create the global temporary table in another TEMP2 tablespace ( which is not the default one) so the load of billions of rows of data will be shifted to TEMP2. The default TEMP tablespace will not be affected and it can be used for other transactions.
Is this possible. Can i shift the global temporary table from TEMP( Default temp tablespace) to TEMP2 ( the non-default temp tablespace) ????
Please guide me with proper solutions and examples ....
Thanks in advance ..

Global temporary tables are instantiated in the temporary tablespace of the schema that inserts the data - not into "the default" temporary tablespace.
Assume Schema1 creates a GTT and grants all on that table to schema2
Assume schema1 also creates a procedure (authid owner, the default) to insert data into the GTT and grants execute on the procedure to schema2
If schema2 executes: insert into schema1.gtt, the data will appear in the temporary tablespace of schema2
If schema2 executes: execute schema1.procedure, the data will appear in the temporary tablespace of schema1
So if you want to protect the "normal" temporary tablespace, you could just create a special temporary tablespace for the owner of the procedure.

Doubt with Global Temporary table

hi,
i have created a global temporary table with ON COMMIT DELETE ROWS option. in my Function in a loop i m inserting values into this Table, after that loop closes and then i m selecting some other values from DB. and in the last i am returning a ref cursor which is selecting values from temporary table i hav created.
now the thing is i m not getting any values in the cursor.
later I have created the table with ON COMMIT PRESERVE ROWS option, in this case cursor returning values,
can anyone explain me the functionality, as per my knowledge global temporary table values are session specific so why i m not getting the values in the 1st case when i used ON COMMIT DELETE ROWS (same session).
Thanks
Piyush

Ok, here's a simple example, like we'd like to see from you not working....
First create a GTT with ON COMMIT DELETE ROWS...
SQL> ed
Wrote file afiedt.buf
1* create global temporary table mytable (x number) on commit delete rows
SQL> /
Table created.Now a simple function that populates the GTT and returns a ref cursor to the data without doing any commits (hence the data should be there!)
SQL> ed
Wrote file afiedt.buf
1 create or replace function pop_table return sys_refcursor is
2    v_rc sys_refcursor;
3 begin
4    insert into mytable
5    select rownum from dual connect by rownum <= 10;
6    OPEN v_rc FOR SELECT x FROM mytable;
7    RETURN v_rc;
8* end;
SQL> /
Function created.So now we call the function and get a reference to our ref cursor...
SQL> var v_a refcursor;
SQL> exec :v_a := pop_table();
PL/SQL procedure successfully completed.So, in principle, because no commits have been issued the ref cursor should return data...
SQL> print v_a;
         X
         1
         2
         3
         4
         5
         6
         7
         8
         9
        10
10 rows selected.... which it does.
Now, what happens if we do that again...
SQL> commit;
Commit complete.
SQL> exec :v_a := pop_table();
PL/SQL procedure successfully completed.... but this time we commit before retrieving the data...
SQL> commit;
Commit complete.
SQL> print v_a;
ERROR:
ORA-00600: internal error code, arguments: [kcbz_check_objd_typ_1], [0], [0], [1], [], [], [], []
no rows selected
SQL>Oracle has (correctly) lost reference to the data because of the commit.
So show us what yours is doing.

Direct Path Loading Issues with Global Temporary Tables - OCI & OCILib

I am writing some code to import data into a warehouse from a CPU grid which computes risk data. Due to the fact a computing grid is used there will be many clients which can load the data concurrently and at any point in time.
Currently the import uses Binding in OCCI and chunking with a prepared statement to import the data into a global temporary table in a staging area after which a stored procedure is called within the same session which will process the data and load the data into a star schema.
The GTT has the advantage that if any clients have issues no dirty data will be left and each client only sees their own instance of the data.
I have been looking at using direct path loading to increase the performance of the load and have written some OCI code to perform the same task. I have manged to import the data into a regular heap based table using the OCI direct path apis. However when I try and use the same code to import against a Global Temporary Table I get an OCI Error (ORA-00600: internal error code, arguments: [6979], [16], [1], [1318528], [], [], [], [], [], [], [], [])
I get error when the function OCIDirPathPrepare is executed. The same issue occurs in both OCI and OCILib.
Is it not possible to use Direct Path Loading against a Global Temporry Table ? Because you can use the /*+ APPEND */ hint and load global temporary tables this way from tools like SQL Devloper / toad which is surely informing the SQL Engine to use Direct Path ?
Looking at the table USER_OBJECTS I can see that for a Global Temporary Table the DATA_OBJECT_ID is null. Does this mean that it is impossible to us a direct path load into Global Temporary Tables ?
Any ideas / suggestions would be really appreciated. If this means redesigning the application then I would appreciate suggestions which would allow many client to quick write processes in a parallel fashion. If this means creating a new parition in a Heap Table for each writer and direct path loading into this table then so be it.
Thanks

Replying to my own message in case anyone else is interested.
I have now managed to successfully load data using direct path into a global temporary table with OCI. There appears to be no reason why this approach will not work.
I loaded data into the temporary table and then issued a select count(*) on the table from within the session and from a new session. The results were as expected.
The resaon for the ORA-006000 error was due to the fact that I had enabled table level parallel loading
ie
OCIAttrSet((dvoid *) context, (ub4) OCI_HTYPE_DIRPATH_CTX, *(ub1) 1*, (ub4)0, (ub4) OCI_ATTR_DIRPATH_PARALLEL, errhp)
When loading a Global Temporary Table the OCI_ATTR_DIRPATH_PARALLEL attribute needs to be zero
This makes sense, since the temp table does not have any partitions so it would not be possible to write in parallel to multiple paritions.

How to update one table from another

I am creating scripts in Oracle 10g. I have a table that has data corruption on three date fields.
I created a table with the following sql of all the affected rows:
CREATE TABLE LSU_INTER_FIX_DATE AS
select request_id,received_date,planned_start_date, actual_start_date
from lsu_inter2_requests_t
where received_date < to_date('01-JAN-1900')
OR planned_start_date < to_date('01-JAN-1900')
OR actual_start_date < to_date('01-JAN-1900')
I then repaired all of the rows with three data fixes
UPDATE LSU_INTER_FIX_DATE
SET received_date = TO_CHAR(received_date,'YY-MON') ||'-'||(TO_CHAR(received_date,'RRRR') + 2000)
where received_date < to_date('01-JAN-1900')
UPDATE LSU_INTER_FIX_DATE
SET planned_start_date = TO_CHAR(planned_start_date,'YY-MON') ||'-'||(TO_CHAR(planned_start_date,'RRRR') + 2000)
where planned_start_date < to_date('01-JAN-1900')
UPDATE LSU_INTER_FIX_DATE
SET actual_start_date = TO_CHAR(actual_start_date,'YY-MON') ||'-'||(TO_CHAR(actual_start_date,'RRRR') + 2000)
where actual_start_date < to_date('01-JAN-1900')
I now want to update the original base table with the corrected data so I wrote the following SQL UPDATE command:
UPDATE lsu_inter2_requests_t aaa
SET aaa.received_date = bbb.received_date
FROM LSU_INTER_FIX_DATE bbb WHERE aaa.request_id = bbb.request_id
When I run this sql Oracle returns the error “ORA-00933 SQL command not properly ended.” How do I update multiple rows in one table from another table that share the same primary key?

When you want to produce a DATE datatype when starting with a string,
you must use TO_DATE() on the SET line!
(TO_CHAR(received_date,'RRRR') + 2000)since when do you do add characters (from TO_CHAR) with a constant number (2000)?
You should NEVER EVER rely on implicit datatype conversion

How we cn avoid the sequence in remote tables through global temporary tabl

Hi,
We have table xx_interface_qualifiers in the remote db and we are inserting the data like this and its on a loop
INSERT INTO xx_interface_qua
(interface_id,
list_line_interface_id, excluder_flag,
qualifier_context, qualifier_attribute,
qualifier_attr_value, qualifier_precedence,
comparison_operator_code, start_date_active,
end_date_active, list_header_name, list_line_no,
creation_date, created_by, last_update_date,
last_updated_by, interface_attribute1

ttt, 'Y',
xxx, xxx2,
xxx3, xxx4,
'=', SYSDATE,
NULL, xxx4, -1,
SYSDATE, '-1', SYSDATE,
'-1', 44 );
We are trying to avoid the hitting of the database every time for a sequence and try to implement the global temporary tables,i mean to say 1st we need to insert the data to TEMP table and then from temp table we cn inseert all the data to xx_interface_qual in a single shot to improve the performance.
But how we cn avoid the sequence in this case as we do not know the sequence in remote side.
Please suggest any other way to improve the performance.

You have an unknown performance problem (that you claim is due to a sequence, but failed to provide any evidence for). Now you want to create more I/O, by writing the data twice. Once into a temp table and then again into the destination table. And do that in order to increase performance?
I do not see how this can solve the underlying, and unknown, performance issue that you claim exists.
Any problem solution needs to start with correctly and comprehensively identifying the problem.
You cannot solve a problem without first knowing WHAT the problem is.

Can I use Parallel execution for Global Temporary table within SP and How

Dear Gurus,
I have Global temporary table as below
Create global temporary table Temp_Emp
empno number,
ename varchar2(20),
deptno number
) on commit preserve rows;
During processing I insert the data into this table and then fire query on Temp_Emp, get the data and pass it to front end.
The SP as shown below
Create or replace procedure get_emp_data
empid in number,
emp_detail out RefCsr -- Ref cursor
as
begin
-- some code here
open emp_detail for
select *
from Temp_Emp
where empno = empid;
end get_emp_data;
Can use Parallel Query execution on Temp_Emp table and how ?
i.e. do need to explicitly use parallel construct in query or is it default.
Because I have many SQL like above (on global temporary tables) within Stored Procedures.
Can anybody give me any suggestion.
Thanking in Advance
Sanjeev

How come you are populating a temporary table and then opening a cursor on this temporary table for the front end to use?
Couldn't you presumably just form a query out of the code you use to populate the temporary table? This is the recommended approach in Oracle.

Auditing data from global temporary table

Hi I have a process that uses a global temporary table.
What it does it serve a consolidation point to merge a lot of data.
Some the former designer decides to use a global temporary table and the row will be gone once it got commit.
However, the data is corrupted occasionally. And ideally we would like to fix the upstream source data but this is too complicated and not feasible.
So we decide to audit the data going into the global temporary table. We want to generate a report on the corrupted data.
However, whenever I commit, the data is gone from the global temporary table and we do not want to set it to commit preserve rows for the global temporary table
Even with autonomous transaction this is not working out as once it commits the data is gone.
Any idea how this can be done. Here are the prototype that I build to demo this:
drop table gt_tst1;
--this is the table its data needs to get audit
create global temporary table gt_tst1(id number); --on commit preserve rows;
drop table not_gt_tst1;
--this table is used for storign the corrupt data and generate report
create table not_gt_tst1 as select * from gt_tst1;
CREATE OR REPLACE PROCEDURE tst_gt_tst1 IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
--if there is a way to do the insert and select once. but it seems it is not working for global temporay table unless change it to on commit preserve rows
INSERT
when m2 = 0 THEN
INTO not_gt_tst1(id)values(object_id)
when m3 = 0 THEN
INTO gt_tst1(id) values (object_id)
select object_id,mod(object_id,2) m2, mod(object_id,3) m3 from dba_objects where rownum < 101;
COMMIT;
END tst_gt_tst1;
select sysdate from dual;
truncate table gt_tst1;
truncate table not_gt_tst1;
select * from gt_tst1;
select * from not_gt_tst1;
execute tst_gt_tst1;
select * from gt_tst1; -- data gone
select * from not_gt_tst1;
--commit
select sysdate from dual;
spool off

The data is poor and the code is poor and the dev and QA env is also poor..
And the business asks us to fix the data..However..we do not have an environment close enough to test it out before it got put into production that is the bottom line.
Heres the dev and QA env cannot be trust to the extent that I can sign off and say it will give the same behavior as the production env
So we would like to minimize the risk as there are other process uses these table and we are not sure if changing this would lead to UN-expected behavior.
We cannot tell some other process rely on the fact that these table got empty out after commit.
