Already existing tables in oracle 10g problem

Hi, i am new to oracle and just installed oracle 10g, my porblem is that when i ran the query i got an error.
SQL> select *
2 from emp;
from emp
ERROR at line 2:
ORA-00942: table or view does not exist
As emp table already exist in database but it does not show result. please help me. Thanks.

i have heared form someone that i should copy some text (from files) or some files which resides in bin folder (i don't know the exact path) in the sql console to access existing tables. is that ture?Not sure what that means... to access existing tables, or to create new ones you have to use Sql commands (or some graphic stuff).
What about reading some documentation ?
System user is a DBA, and can possibly read any tables, but most probably is not the owner of emp table. To know it you can do
SQL> select owner from dba_tables where table_name='EMP';
then connect to that user, or, as system user, do
SQL> select * from <owner>.emp;

How to overwrite a log and bad file in external table in oracle 10g

Hi,
I have used external table in oracle 10g.whenever use select query in external table orace internally create one log file in specified directory,
but this log file is growing.How can i overwrite the log file(old to replace with new).I need overwrite a log and bad file in external table.
kindly give the solutions.

Siva

I don't believe that is possible with the LOGFILE clause, but it may be with the BADFILE clause. Here is an excerpt from the documentation :
The LOGFILE clause names the file that contains messages generated by the external tables utility while it was accessing data in the datafile. If a log file already exists by the same name, the access driver reopens that log file and appends new log information to the end. This is different from bad files and discard files, which overwrite any existing file. NOLOGFILE is used to prevent creation of a log file.
If you specify LOGFILE, you must specify a filename or you will receive an error.
If neither LOGFILE nor NOLOGFILE is specified, the default is to create a log file. The name of the file will be the table name followed by _%p and it will have an extension of .log.

Retrieve data from a large table from ORACLE 10g

I am working with a Microsoft Visual Studio Project that requires to retrieve data from a large table from Oracle 10g database and export the data into the hard drive.
The problem here is that I am not able to connect to the database directly because of license issue but I can use a third party API to retrieve data from the database. This API has sufficient previllege/license permission on to the database to perform retrieval of data. So, I am not able to use DTS/SSIS or other tool to import data from the database directly connecting to it.
Here my approach is...first retrieve the data using the API into a .net DataTable and then dump the records from it into the hard drive in a specific format (might be in Excel file/ another SQL server database).
When I try to retrieve the data from a large table having over 13 lacs records (3-4 GB) in a data table using the visual studio project, I get an Out of memory exception.
But is there any better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?
Any help on this problem will be highly appriciated.
Thanks in advance...

Girish...Thanks for your reply...But I am sorry for the confusions. Let me explain that...
1."export the data into another media into the hard drive."
What does it mean by this line i.e. another media into hard drive???
ANS: Sorry...I just want to write the data in a file or in a table in SQL server database.
2."I am not able to connect to the database directly because of license issue"
huh?? I never heard this question that a user is not able to connect the db because of license. What error / message you are getting?
ANS: My company uses a 3rd party application that uses ORACLE 10g. And my compnay is licensed to use the 3rd party application (APP+Database is a package) and did not purchased ORACLE license to use directly. So I will not connect to the database directly.
3.I am not sure which API is you are talking about, but i am running an application of the visual studio data grid or similar kind of controls; in which i can select (select query) as many rows as i needed; no issue.
ANS: This API is provided by the 3rd party application vendor. I can pass a query to it and it returns a datatable.
4."better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?"
ANS: As I get a system error (out of memory) when I select all rows in a datatable at a time, I wanted to retrieve the data in multiple phases.
E.g: 1 to 20,000 records in 1st phase
20,001 to 40,000 records in 2nd phase
40,001 to ...... records in 3nd phase
and so on...
Please let me know if this does not clarify your confusions... :)
Thanks...

New address creation for already existing customer in Oracle

Hi,
We are working on customer conversion and loading all the data into customer interface tables so that we can run the customer interface to move the data into oracle tables.
We need to create another address as per client’s requirement to already existing customer in oracle which has active primary bill_to address.
Can we do this by using customer interface tables or use the API’s for it.
Any pointers regarding this will be highly appreciated.
Thank and Regards,

Replication of table from Oracle 10g to sql server 2000

Could i replicate table from Oracle 10g to sql server online. we have tables with same configuration and if any change happen in oracle 10g or sql server in that table we need to replicate that change to other database.
What is the solution for this two way replication between sql server and Oracle 10g

But the tutorial is saying that i will have to install Oracle database on the server already having sql server, is it client or whole database, if it is then it will acquire lot of resource.
I want to find out that for Heterogenous Service ODBC, we need third party software for ODBC Driver of SQL SERVER for Linux and secondly if we use Transparent Gateway then what are the steps for its configuration.
I could not find steps of configuration of Transoparent gateway, when i am trying to install Transparent gateway from Universal installer, it is not there. where do i find it , Do i need to purchase it too.

How to migrate a table from ORACLE 10g to 8i

have table named 'liuxg_tab_01' in 10g.
This morning I exported this table using 'exp' and then tried to imp it into 8i, I failed.
After a while, I created a database link named 'ctf' in 8i which connected to 10g. I issued 'create table test as selct * from liuxg_tab_01@ctf',it returns 'ORA-01723'.
Then I extraced the DDL of 'liuxg_tab_01' from 10g with QUEST TAOD, it's:
CREATE TABLE LIUXG_TAB_01
OWNER VARCHAR2(30 BYTE),
OBJECT_NAME VARCHAR2(30 BYTE),
SUBOBJECT_NAME VARCHAR2(30 BYTE),
OBJECT_ID NUMBER,
DATA_OBJECT_ID NUMBER,
OBJECT_TYPE VARCHAR2(19 BYTE),
CREATED DATE,
LAST_DDL_TIME DATE,
TIMESTAMP VARCHAR2(19 BYTE),
STATUS VARCHAR2(7 BYTE),
TEMPORARY VARCHAR2(1 BYTE),
GENERATED VARCHAR2(1 BYTE),
SECONDARY VARCHAR2(1 BYTE)
But I can not create a table using the upper DDL in 8i if I do not wipe off those "BYTES".
After creation of the table using the upper DDL without those 'BYTES', I sucessfully executed 'insert into LIUXG_TAB_01 select * from liuxg_tab_01@ctf'.
Anyone has a better method to move a table from ORACLE 10g to 8i?

1) The particular version of 8i and 10g in use here would be useful. I'm not sure that Oracle supports database links between any version of 8i and any version of 10g, though, so you're probably lucky that it worked as well as it did.
10g 10.1.0.3.0 and 8i 8.1.7.0.0
2) What version of the export utility did you use? You would need to use the 8i version to generate the dump file to have any chance of working, not the 10g verion.
I use the 'exp' provided with 10g 10.1.0.3.0 and 'imp' with 8i 8.1.7.0.0. I have tried to export data directly from 10g 10.1.0.3.0 using 'exp' provided with 8i 8.1.7.0.0. Failed.
3) Why? Since 8i is desupported, there isn't a lot of call for tools to move data from supported releases to unsupported releases.
We have an 8i DB which is still porivding insentive services. We just wanna migrate some tales from 10g to it.
FYI, NLS_LENGTH_SEMANTICS was introduced in 9i, so it's no suprise that 8i objected to the BYTE keyword in the DDL.
What's FYI :P
Another option would be to generate a CSV file of the data from 10g and use SQL*Loader to load it into 8i. Not sure this would be any easier, though.

How add primary key constraint to already existing table with data

I want apply primary key constraint to already existing table with data
is there any command or way to do

Alternatively, assuming you want to ensure uniqueness in your primary key column you can do this:
alter table <table name> add constraint <cons name> primary key (col1,col2) exceptions into <exception_table>
If the altter table statement fails this will populate the EXCEPTIONS table with the rows that contain duplicate values for (col1,col2).
You will need to run (or get a DBA to run) a script called UTLEXCPT.SQL (which will be in the $ORACLE_HOME/rdbms/admin directory) if you don't already have an EXCEPTIONS table.

External table in Oracle 10g and Windows server 2003 problem

I'm having a problem accessing an external table in an Oracle 10g and Windows 2003 server environment. The disk is remote (mapped) to the server. It's the usual access errors, kup-04001 or kup-04063.
I have the [seemingly] exact same setup in an Oracle 9i and Windows 2000 server environment which works perfectly. Services run as local SYSTEM and SYSTEM has full permissions on the disk. Directories exist and so do the permissions to the directories.
In the Oracle 10g and Windows 2003 environment, services run as local SYSTEM and SYSTEM has full permissions on the mapped disk. Directories exist and so do the permissions to the directories.
This obviously effects mappings, deployments, etc.
Does anyone know if something changed in either the db or the os?
Thank you,
Michael

Thank you for your reply.
Your proposal is the standard solution. As a matter of fact, that's how it is on my "old" system. Server "A" Oracle services are started by SYSTEM. Server "B" Oracle services are started by SYSTEM and is where the flat files reside. SYSTEM has full permissions on a disk local to Server "B". Database directoriies defined on Server "A" point to Server "B" remote disk. External Tables on Server "A" are defined with directories that point to Server "B" remote (mapped) disk. I have no problems with this configuration.
I'm having a problem acheiving the same configuration with Oracle 10g and Windows 2003. I guess I'm baffled over the fact it isn't working the same way as my "old" environment. Why shouldn't it? Oracle (and you) want me to start services as a specific user. It shouldn't have to be that way unless something changed in the way the database makes calls to the os or if Microsoft slipped something in with one of it's numerous security patches.

Problem with global temporary table in Oracle 10g

Hi All,
I face a peculiar problem in Oracle 10g with respect to Global temporary table.
Have Oracle 10g version in Production and 11g version in UAT.
Table_
create global temporary table TT_TEMPGPSMANUAL
Col_1    VARCHAR2(50),
Col_2    VARCHAR2(500),
Col_3    VARCHAR2(50),
Col_4    VARCHAR2(50),
Col_5    VARCHAR2(15),
Col_6    VARCHAR2(20),
Col_7    VARCHAR2(250),
Col_8    VARCHAR2(20),
Col_9    VARCHAR2(15),
Col_10   VARCHAR2(20),
Flag     NUMBER,
Col_11   INTEGER,
Col_12   VARCHAR2(50)
on commit preserve rows;So this should preserve the rows inserted into this table until the session ends.
Have a webpage in front-end where in turn, it opens another page (session is carried through) and a few rows will be inserted to this table from the webpage (through a function) on submit and the current page will be closed.
From the parent page, if I open the sub-page data inserted in the temporary table are held and displayed (another function to fetch the values in the Global Temp table).
The Problem in Oracle 10g (Production) is, this is not happening properly. When I close and open the sub-page, not every time I get the data stored i.e if I close and open the page 10 times, atelast 4 times the data is missed in the page (I am not getting values from temp table) randomly.
But this does not happen in UAT (which has Oracle 11g installed) as I get the data in the webpage consistently. After passing UAT, when we rolled out to Prod, getting this issue which we are unable to get what could be the reason.
It is very hard to debug using GTT dynamically in prod. It takes time to get Oracle 11g installed in Prod.
Can anyone suggest?
Regards
Deep

(I am not aware exactly and have the impression that, as the second page is a child, I guess it would take the same session).I'm not sure what "sub-page" or "parent page" means to you. If you're just linking from one page to another, "parent" and "child" don't really make sense since page A links to page B and B links to A quite frequently.
Assuming that you have to log in to access the site, it is likely that the two pages share the same middle tier application session. It is unlikely that the middle tier would hold the database session from the first request open waiting to see if the user eventually requested the second page. It is theoretically possible that you could code your middle tier this way but it is extremely unlikely that you would want to do so for a variety of reasons. So, when you say "would [the] session ... be changed", it is likely that the application session would be the same for both calls but that the database session would be different.

Partitioning tables in Oracle 10g

Hi,
I have a table that already contains more than a million of records, I am considering partitioning it, I am new with the web based console of oracle 10g, so I am not finding the way to do it.
can any one help me?

Well, search on "Creating Partitioned Tables" in OEM help and that will tell you how to get to the partitions page for when you are creating a new table. I figured modifying an existing table would be in the Storage tab of that area but I didn't see it. For an existing table, it might be easier just to use SQL Plus.
Or you can use OEM to create a new empty table with partitions and just do a select into... on it.

Viewing Tables in Oracle 10g Enterprise Manager

Hello,
We are running Oracle 10g on a Linux Red Hat platform. We have started the dbconsole listeners to start using Enterprise Manager. The problem we are encountering is that tables that are in our schema are not showing up in Enterprise Manager. We have checked the tables using OEM and they are appearing there normally. The tables not showing were created from an object type. We are able to use DML, DDL on these tables using SQL, iSQLPlus. We appreciate any ideas. Thanks.

Please clarify how did you check the tables in 10g using EM dbconsole.
Please post some screen capture of you login using sqlplus and shown the table is there for example,
%sqlplus test/test1
