ORA 7 & temp tables?
Used migration workbench to migrate an MSS database into ORA 8i and all is well after a bit of re-jiggering. Migration Workbench modified MSS temporary table references to ORA Global Temporary Tables.
May need to implement same database structure in ORA 7 for some customers. Does ORA 7 also support temporary tables? In the same manner as 8i? Can't find any reference to them in the ORA 7 docs.
Thanks
So I just create ordinary tables and flush them out manually in ORA 7 ?
If that is correst, any techniques you can suggest when doing a "DELETE FROM" on these working tables to eliminate filling up the transaction log when these tables may be quite big? Is TRUNCATE TABLE supported within the bounds of a transaction in a Trigger or Procedure in ORA 7?

This is the error I get in the Apache log. On the page:
"The requested URL /pls/apex/wwv_flow.accept was not found on this server."
I am sure this is just a configuration issue. I installed v1.6 with the http server off the companion cd with the db (10.2.0.1). After I had it working (did not test everything) I upgraded to 3.0.1.
I get this message when I am trying to import an application that I just exported! I am testing this for pushing code up to our production environment.

There is a log file for pl/sql.... it has the following text in it that seemed pertinent: Attempting to logon with '(unknown)'
Also a log that says this and seems to have a "special character" in it that may be causing an issue:

I did go in and update the permissions to the wwv_flow_file_objects$ table to give PUBLIC full access to that table to see if that was the problem... it wasn't.
Probably information overload, but just wanted to be thorough. Anyone have any ideas?I also have another issue... probably more of a clarification....
I run the following to stop the process:
"/oracle/product/apps/opmn/bin/opmnctl stopproc ias-component=HTTP_Server"
then
"/oracle/product/apps/opmn/bin/opmnctl startproc ias-component=HTTP_Server"
But, at that point, it says that opmn is not running.
So I try:
"/oracle/product/apps/opmn/bin/opmnctl stopall"
then
"/oracle/product/apps/opmn/bin/opmnctl start"
then
"/oracle/product/apps/opmn/bin/opmnctl startproc ias-component=HTTP_Server" and it still says that opmn is not running.
Once I start running the stops and starts, it will eventually start correctly.
I think that I am trying the steps too fast and that I probably need to wait a bit between steps since that seems to work better that way. -
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.
ThanksIN 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. -
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:

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.

Physical attributes for index on temp tables (using physical model)
I need create index on temp tables.
When I generate DDL, it includes physical attributes like ‘LOGGING NOCOMPRESS NOPARALLEL’.
I get error "ORA – 14451 (unsupported feature w/temporary tables)"
I’ve to use physical model in OSDM. How do I get rid of physical attributes in DDL for index?Hi,
Thanks for reporting this problem.
You can remove the LOGGING clause by opening the Properties dialog for the Index in the Physical model and setting its Logging property to the blank option.
However it's not possible to suppress the NOCOMPRESS and NOPARALLEL at the moment.
I've logged a bug on this.
As a workaround, you could do a global edit on the DDL file to remove all instances of NOCOMPRESS and NOPARALLEL.

We are currently converting our student information system from Sybase to Oracle. My task is to convert our existing sql scripts. A number of them use temp tables and I have successfully got them to run except that I cannot drop the tables at the end of the script because they are still in use *[Error Code: 14452, SQL State: 72000] ORA-14452: attempt to create, alter or drop an index on temporary table already in use*.

Temp tables left behind by SDO_PC_PKG methods?
I have a bunch of MDPCE tables after playing with SDO_PC_PKG last week.
Are these temp tables left behind by SDO_PC_PKG methods? Is it safe to drop them?
What circumstances could have left them behind, and why were they committed when the call to the PL/SQL method crashed the client program? (copy/paste error in my OCI code).

PL/SQL to create a temp table that will be dropped after session ends
Is it possible in PL/SQL to create a temp table that will be dropped after the session ends? Please provide example if possible. I can create a global temp table in PL/SQL but I am not sure how (if possible) to have it 'drop' once the session ends.
DB: 10g
OS: Wiindoze 2003 Server
:-)As others have mentioned (but probably not clearly explained), Oracle treats temporary tables differently to SQL Server.
In SQL Server you create a temporary table and it gets dropped (automatically I assume, I dont do SQL Server) after the session finishes. This will obviously allow each session to "request" a temporary table to use, then use it, and not have to worry about cleaning up the database after the session has finished.
Oracle takes a different approach...
On the assumption that each session is likely to be creating a temporary table for the same purposes, with the same structure, Oracle let's you create a Global Temporary Table a.k.a. GTT (which you've already come across). You only have to create this table once and you leave it on the database. This then means that any code written to use that table doesn't have to be dynamic code and can be verified and checked at compile time, just like code written for any other table. The difference of a GTT from a regular table is that any data you put into that table can only be seen by that session and will not interfere with any data of other sessions and, when you either commit, or end the session (depending on the "on commit delete rows" or "on commit preserve rows" option used when creating the GTT), that data from your own session will automatically be removed and hence the table is cleaned up that way, whilst the actual table itself remains.
Some people from SQL Server backgrounds try and create and drop tables dynamically in their PL/SQL code, but this leads to problems...
SQL> ed
Wrote file afiedt.buf
1 begin
2 execute immediate 'create table my_temp (x number)';
3 insert into my_temp values (1);
4 execute immediate 'drop table my_temp';

They then try and get around this issue by making their DML statements dynamic too...
SQL> ed

ORA-01722: invalid number
ORA-06512: at "SCOTT.MY_PROC", line 4
ORA-06512: at line 1... oops the code has a bug in it. Our DML statement was invalid.
This is really something that would have been caught at compile time, if the statement had been a direct DML statement rather than dynamic. And thus we see the problem with people trying to write all their code as dynamic SQL... it's more likely to contain bugs that won't be detected at compile time and only come to light at run time... sometimes only under certain conditions and sometimes once it's got into a production environment. Bad Idea!!!! ;)
Far better to never create tables (or most other database objects) at run time. Just create them once as part of the database design/implementation and use them as required, allowing you to catch the most common coding errors up front before they get anywhere near a test environment or worse still, a production environment. -
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?

We had a similar problem and I found help in the following thread:
Re: Global temp table problem w/ODP?
All the best. -
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.
thanksHi 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

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 VoteCheck 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.

PL/SQL: ORA-00942: table or view does not exist

i wrote a function which should give me new_sno when i give it the old_sno
and i have this errors , pls help
CREATE OR REPLACE FUNCTION ORIG_SN(OSNO in Number,OTN in Number)
RETURN Number IS
NEW_SNO Number:=0;
BEGIN
SELECT new_sno AS NEW_SNO
FROM DAD.SCHOOL
WHERE ORIG_SNO = OSNO AND ORIG_TN = OTN;
RETURN NEW_SNO;
END ORIG_SN;
Warning: Function created with compilation errors.
Errors for FUNCTION ORIG_SN:
LINE/COL ERROR
5/1 PL/SQL: SQL Statement ignored
6/15 PL/SQL: ORA-00942: table or view does not exist
Thanks in advance ..Try this,
CREATE VIEW SCHOOL_VIEW AS SELECT * FROM DAD.SCHOOL;and then change your function like
CREATE OR REPLACE FUNCTION ORIG_SN(OSNO in Number,OTN in Number)
RETURN Number IS
my_new_sno Number:=0;
BEGIN
SELECT new_sno INTO my_new_sno FROM SCHOOL_VIEW WHERE ORIG_SNO = OSNO AND ORIG_TN = OTN;
RETURN my_new_sno;
END ORIG_SN;and see if it is getting created without any errors.

ORA-00604: error occurred at recursive SQL level 1 ORA-04063: table....
Hi all,
i have the following code:
DROP TYPE unit_function FORCE
DROP TYPE unit_moving_point FORCE
DROP TYPE moving_point_tab FORCE
DROP TYPE moving_point FORCE
DROP TABLE moving_object_ref
DROP TABLE moving_point_ref
CREATE OR REPLACE TYPE unit_function AS OBJECT
xi NUMBER,
yi NUMBER
CREATE OR REPLACE TYPE unit_moving_point AS OBJECT
p tau_tll.d_period_sec,
m unit_function
CREATE OR REPLACE TYPE moving_point_tab AS TABLE OF unit_moving_point;
CREATE OR REPLACE TYPE moving_point AS OBJECT
u_tab moving_point_tab
CREATE TABLE moving_point_ref OF moving_point NESTED TABLE u_tab STORE AS m_u_tab
When i execute this for the first time the drop commands fail, as expected and the types/tables are successfully created. But if i try to run again the same code i get this error:
ORA-00604: error occurred at recursive SQL level 1 ORA-04063: table "HERMESL.MOVING_POINT_REF" has errors
I have tried to first drop the tables and after the types but then I get this error:
ORA-00604: error occurred at recursive SQL level 1 ORA-22914: DROP of nested tables not supported
this error occurs when the "DROP TYPE unit_function FORCE" and "DROP TYPE unit_moving_point FORCE" commands is to be executed...
Can anyone help me?
Thanks...Works on 10.1.0.3.
What is your exact version?
