I want to export below things from SQL developer
1-Only schema (tables structure)
2-Only data in excel form
3-Schema with data
after exporting this i want to import the same to the another database
So what steps should i follow for export and import?
I can not use DATA PUMP as i don't have DBA privilege
As you use Oracle 11g, I'd suggest you to forget about SQL Developer and use the original EXP and IMP utilities. Doing so, you'd avoid DBA-related-problems as these utilities don't require access to the directory (an Oracle object which points to (usually database server's) filesystem directory, and - in order to be able to use it - you'd need to have read/write privileges on it).
So - if you don't already have these, install Oracle Client which contains EXP/IMP and use them.

I'm trying to export an Oracle DB using Oracle SQL Developer having tables, sequences, view, packages, etc. with dependencies on each other.
When I use Tools -> Database Export and select all DDL options, unfortunately the exported SQL file does not preserve the other that is some DB objects should be created before some other.
Is there a way to make the DB export utility preserve object dependencies/order? Or Is there any other tool do you use for this task?
Thank you
Normally expdp does a pretty good job. Problems arise when there are dependencies on objects/users that are not part of the dump. This is because the counter part, impdp, does not add grants on objects that are not created by impdp. I call that the 'not created by me syndrome' that impdp has.
If you have no external dependencies (external meaning to schema's that are not part of the dump), expdp/impdp do a good job for you. You might not be able to use it if you can not have access to the database server since expdp writes it's files on the database server.
If you happen to have access to a database server that is able to connect to the original database, you could pull the data over into your local database using a database link.
I'm one of the junior DBA working in IT company.In my company there are so many schemas is there.Now my question is How to create a dump file(some times i'm working at home.That time how to use that dump file ).Please suggest me
NOTE:I am using Oracle SQL Developer.
Expdp helps in exporting the database and impdp helps in importing the database. you can directly export one schema to another (in different database also) by using network link concept.
If network link concept is used then the creation of separate expdp file is not required.
For example If you have to export a schema called schema1 with password pwd1 from source database to target database then
first you need admin privileges of your target and source schema.
You can create a network link between source and target schema
CREATE PUBLIC DATABASE LINK example_link
CONNECT TO schema1 IDENTIFIED BY pwd1
USING 'server_name:port/service_name';--(put source database server_name,port and service name)
then create a directory in your target server :-
CREATE OR REPLACE DIRECTORY exp_dir AS 'F:/location';
grant read,write on directory exp_dir to schema1;
After this login to your target server and from command line use the below command:
impdp dba_username/dba_pwd network_link=example_link directory=exp_dir remap_tablespace=source_tbs:target_tbs remap_schema=schema1:schema1 parallel=2
You should use the Oracle Data Pump tool. The tool allows you to export your data into a .dmp file and import it into any database. Here is a video showing how to use the data pump tool in SQLDeveloper. I think this is a relatively new feature in SQLDeveloper, so make sure you have the appropriate versions..
Video Tutorial HERE
From the command line, you can use data pump with the expdp and impdp commands like so..
Set your oracle environment by running the below command and providing your oracle SID
. oraenv
Then you can run your export command..
expdp directory=/bu1/dpdump/ dumpfile=myexport.dmp logfile=mylog.log schemas=users,products,sales
The parameters are as follows..
directory - the directory where to create the dumpfile and log
dumpfile - name of the dump file (should end in .dmp)
logfile - name of the log file (should end in .log)
schemas - comma seperated list of the schemas you want to export
NOTE: you need dba privileges to use datapump. It will prompt you for the credentials
Data Pump Documentation is here
Exporting of ORACLE database objects is controlled by parameters. To get familiar with EXPORT parameters type:
exp help=y
You will get a short description and the default settings will be shown.
The EXPORT utility may be used in three ways:
Interactive dialogue
Controlled through bypassed parameters
Parameterfile controlled
Example to the 2nd option:
exp scott/tiger file=empdept.expdat tables=(EMP,DEPT) log=empdept.log

Really would appreciate any help whatsoever on this one.
How to generate DDL from Application Express... including the actual data.
I can create a DDL; but one which contains none of the necessary inserts into the database tables. :<
There is no command console in Application Express.
You could use another tool, such as SQL Developer, which can export the data as INSERT statements; alternatively, use Oracle's schema export utility (expdp) which can either export just the data or the entire schema if you like.
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 have an Oracle database on one PC. I have to migrate it to my other PC. Both use separate oracle installations. Now how can I export it from my one PC and then import it into other PC?
What are the commands for exporting and then importing it?
I want structure as well as data to be exported and then imported. I am using Oracle db.
You can export the data from your source database and import it into your new one.
A good link demonstrating the usage of these commands can be found here
It boils down to something like the following for exporting a full database:
%> exp USERID=<username>/<password> FULL=Y FILE=dbExport.dmp
%> imp USERID=<username>/<password> FILE=dbExport.dmp FULL=Y
There are a multitude of options for both commands to tailor it to your needs. For example, you can restrict the import command to only import certain tables via the TABLES parameter or you can move database object between users with TOUSER, FROMUSER parameters. There are also options on whether to export or import constraints, indexes, etc. You can find all the valid parameters for both commands by executing either:
%> exp help=Y
%> imp help=Y
You don't say which version of the database you are using. This is important information, because new features get added to Oracle with every release. For instance, in 10g Oracle introduced a new utility, DataPump, which replaces the older IMP and EXP (those utilities are still included in the install, they are just deprecated).
One of the neat things about DataPump is that we can execute from inside the database as well as from an OS command line. I recently posted an example of using DataPump from PL/SQL in this SO thread. `Oracle provide comprehensive documentation.
edit
Neither old fashioned IMP/EXP nor DataPump generate an SQL file (*). If that is really what you want (as opposed to just porting the schema and data somehow) then things get a bit trickier. Oracle has a package DBMS_METADATA which we can use to generate DDL scripts, but that won't deal with the data. To generate actual INSERT statements, your best bet is to use an IDE; Quest's TOAD will do this as will Oracle's (free) SQL Developer tool. Both IDEs will also generate DDL scripts for us.
(*) A Datapump import can derive the DDL statements from a prior Datapump export file, using the SQLFILE= parameter. But that is just the structure not the data.
