How can I export data from Oracle 8i database using command which I can run through oracle cli?
My biggest problem is, the data should be exported based in the query I use...
For ex,
select * from emp where emp_id>4
should dump the records having emp_id>4.
I don't have permission to use functions.
Please help!!
Oracle provides a set of tools that are designed for exporting data (the exp tool, for instance). These don't run via the SQL*PLUS command line (which I assume is what you mean by CLI), although they do connect via NET*8. From Oracle 8i onwards, you can use the query parameter to limit the rows exported:
exp scott/tiger tables=emp query="where deptno=10"
But you have to have the Oracle client installed and be able to connect to the database via SQL*NET.
If all you have is the ability to run queries, you're out of luck unless you can write a query that generates a CSV (tricky if you don't have the ability to call/write functions). It sounds to me like all you have access to is a web interface.

Data was sent to our company with PostgreSQL, but we are prohibited to use the tools of PostgreSQL , permitted the use of only Oracle.
How to migrate data from PostgreSQL to Oracle without using a third party application(they are also prohibited)? You can only use the tools of Oracle.
I found this article https://support.oracle.com/knowledge/Oracle%20Database%20Products/2220826_1.html but we don't have Support Identifier
We have one .sql file. It weighs 8 Gigabytes.
It looks like you have so many impediments in your company. Regarding Oracle's SQL Developer Migration Workbench, unfortunately it does not support the migration of PostgreSQL databases. However, the following 3rd-party software tools are available and may assist in migration, but I am afraid you cannot use them as you said that those products are forbidden:

Other options will only move the data from your Postgresql database to Oracle database, it means that you must have the DDLs of the tables before to run the import:
To move data only, you can generate a flat file of the the
PostgreSQL data and use Oracle SQL*Loader.
Another option to migrate data only is to use Oracle Database
Gateway for ODBC which requires an ODBC driver to connect to the
PostreSQL database, and copy each table over the network using
sqlplus "COPY" or "CREATE TABLE AS SELECT" commands via oracle
database link.
Also, Oracle has discussion forum for migrating non-oracle databases to Oracle.
http://www.oracle.com/technetwork/database/migration/third-party-093040.html
But, if you have only a sql file, you should look at it to see whether you have both DDLs ( create tables and indexes, etc ) and the data itself as insert statements. If so, you need to split it and treat the DDLs to convert the original data types to Oracle datatypes.
I have a csv file which has to be bulk imported to oracle dB. I was working on other sybase dB engine before so I had a sample script which has the environment setup for it. Right now I have to do the process in a oracle dB so what should be the first line I know about the rest other parameters but want to know the path which has to be defined when I write
path/bcp dbtable in data.txt
If anyone could help what should be the path for oracle dB
The primary tools for bulk or flat file loading are:
SQL*Loader
External Tables (and here)
GUI Tools like SQL*Developer
It is much more cumbersome, but if necessary you can roll your own solution with the UTL_FILE PL/SQL package.
I have a Oracle server which is very highly loaded. I want to Select big table with several millions rows of data and download the data using SQL Developer. How I can do this with little performance impact of the production database?
use oracle's export tool for most efficient dump of data from a table.
example
exp user/password tables=mytable query="optional where clause here"
Note you have to have oracle client installed to use it.
i am newbie to oracle and i like to export database from remote database and import it on local machine. eOn both machines i have oracle 10.2.
I need to know how to export/import schema and data from oracle 10.2 using SQLDeveloper 3.0.0.4.
To export from remote database, i have used export Tool-> Database Export -> export wizard.
and at the end i have got only sql file with DDL and DML statements but somewhere in file it is written
"Cannot render Table DDL for object XXX.TABLE_NAME with DBMS_METADATA attempting internal generator error.
I have ignored previously mentioned message and tried to run those DDL and DML statements but all this ended up with errors.
Is it possible that all this tied with read-only database user? More over, i dont find any table under tables but also tables under other users in SqlDeveloper.
Thanks in advance
As a test, can you select one object in the tree, and navigate to the script panel? SQLDEV also uses DBMS_METADATA to generate those scripts.
Also, as a work-around, try using DataPump to export and import your data. It will be much more efficient for moving around larger schemas.
Your note about not seeing tables under indicates your schema doesn't actually own any tables. You may be working with synonyms that allow you to query objects as if they are in your account. You could be running into a privilege issue, but your error message doesn't indicate that. Error messages often come in bunches, and the very first one is usually the most important.
If you could try using the EXPORT feature say against a very simple schema like SCOTT as a test, this should indicate whether there is a problem with your account settings or with the software.
I'm not sure with SQL Developer 3.0 but with version 3.1 you can follow this:
SQL Developer 3.1 Data Pump Wizards (expdp, impdp)
I need to export a number of rows (from different tables- ie, all the related information about an entity - for eg: a Customer) to another DB in Oracle. How do we do this? I am using a windows OS. Please help.
Thank you all,

While connected to database 1 you could also create a database link to database 2 (if you have rights to do so - there were no assumptions on this) and insert to your tables by selecting from your link e.g. like this
CREATE DATABASE LINK foo
CONNECT TO <user> IDENTIFIED BY <password>
USING '<connect string>';
select * from table1#foo;
Further information:
A database link is a connection
between two physical database servers
that allows a client to access them as
one logical database.
See Dabtabase links at Oracle Database Administrator's Guide.
You can use Oracle's export and import utilities
You might want to give Data Pump a try as well (depending on your version). Many options for moving around data from Oracle -> Oracle dbs
Another option is the SQL*Plus copy command. It's not very fast, but it can be very convenient in certain contexts.
Oracle's SQL developer tool has the option to export data as insert statements.
