I need a command for importing a table for the following scenario.
I have a table EMPLOYEE in server A. I am exporting the Table.
I have another table PDATA(having same structure of EMPLOYEE table) in server B.
I need to import the records from EMPLOYEE table(server A) into PDATA table(server B).
I am using Oracle 10g. Please advise.
There are a couple of options. I am going to assume that you don't have any binary data and that the tables aren't absurdly large. We also don't know what type of access you have to either server.
You could use a tool, such as TOAD, to either export to csv or create insert statements. Then execute those on the second server.
You could use PL/SQL and the UTL_FILE library to dump the contents of the table to a csv file. Then mount the csv file as an external table and select into your new table.
If you have the appropriate permissions and the machines can physically see each other you can setup a database link: http://docs.oracle.com/cd/B14117_01/server.101/b10759/statements_5005.htm Once the link is created, you can select from one table into the other.
If you are a DBA then you can use the Export utility, which will export the table into a binary format that can be imported elsewhere.

How can i transfer single table data from one Database to other database with same table name?
I have a database with data and other one has no data.
They are not exactly the same as but one table is the same
Thanks
There are many ways to export a table. Some are,
Using SELECT INTO Query
Select * into Database1.Department from Database2.Department
Using SQL Server Export / Import wizard
a. From SQL Server Management Studio, right-click on the database name in the object explorer, then choose Tasks -> Export Data
b. Choose a Data Source and Destination
c. Select the source table and follow the steps and execute the package

Edited Note:
The above methods are for Microsoft SQL Server.
I have a txt file containing a table with two columns student ID and GPA. I want to create a similar table in Oracle SQL developer. Is there some way to copy this data directly into SQL developer
If you are looking for a simple GUI method, you can connect to a db, right click on "Tables", "import data..." and use the Data Import Wizard.
Select the correct options (csv/delimited, tableName, cloumnsToImport...) and click "Finish".

You can create external table with that file, then copy the external table into a new internal table (usual table), here is a full example:
External Tables Concepts
Then go to:
Example: Creating and Loading an External Table Using ORACLE_LOADER
Using a SQL tool like SQL Developer / Toad for Oracle
Is it possible to write a SQL query that will do the following
SELECT * FROM TABLE
WHERE COLUMN1 IN CSV_FILE
The CSV file is just one column of data with no delimiters.
How can I achieve this?
Constraints
I cannot create a temp table to insert CSV file (no create permissions)
The data I am using of this column is the only index in that table so I cannot use other columns to query or else it will be really slow.
Thanks
Creating external table is the best way. If you dont have permission then the other way is to move the file to the path of any oracle directory(Oracle object - Directory). And with help of utl_file read the file, loop through it and do your operation inside a PL/SQL block which is too tedious.
See the eaxmples for using utl_file - http://psoug.org/reference/utl_file.html
But its better if you try and get create access.
Toad for Oracle data import (uses sqlldr internally)
Create a temp table and load the data using this utility and select the values
External tables
Create external table, load the data through the same and select the values.
Using SQL developer you can create a table in your schema and load this table with data from a csv file.
Notes:
You will need to create a void column per each column to import from excel
Excel export csv with ";" delimiter
If SQL developer(4.1.5) doesn't preview the fields in separated columns try moving forward/backwards with Next/back buttons
and a very graphical guide in the following page:

I want to Copy a data from One oracle database to another.
I have checked Import/Export Utility but the problem is import utility doesn't support conflicts resolution techniques between rows.
For Example if there's a table in the source database have the same row key in the destination database. if i use 'Ignore' parameter with value = y, the destination table will have a duplicate rows.
I want to ask if there's another way to import data from oracle database to another with some mechanism of detecting the conflicts and resolve them?
You might want to consider using a database link from database A to database B. You can query the data from database B to insert into your database A tables. You are free to query whatever you want using SQL or PL/SQL.

I want to create update script for BLOB column in Table which stores XSL Data in ORACLE. Can anybody help me in simple way without creating any directory. Here number of character involved is also more than 4000.
I have modified in TOAD by 'Save to File' and again from 'Load to File'. Now I want to transfer it to some other database using SQL Script.
Using the Oracle IMP and EXP utilities you can export a table into a file and import it into another database. Here is some information on how to use them:

It is not SQL but it also doesn't involve creating directories.
