To import an Oracle table from a dump file, you can use the Oracle Data Pump utility, which allows you to import data and metadata to an Oracle database from a dump file created by the Data Pump Export utility. Here is a step-by-step guide to import a table from a dump file:

  1. Ensure that you have the required privileges to perform the import operation on the Oracle database.
  2. Copy the dump file (with the .dmp extension) to the server where the Oracle database is located.
  3. Connect to the Oracle database using SQL*Plus or any other Oracle client tool.
  4. Run the following command to start the Data Pump Import utility:
1
impdp username/password@db_alias directory=directory_name dumpfile=dumpfile_name.dmp


Replace 'username' with your Oracle username, 'password' with your password, 'db_alias' with the database connection alias, 'directory_name' with the Oracle directory object where the dump file is located, and 'dumpfile_name.dmp' with the name of the dump file.

  1. Specify the tables and schemas you want to import by adding the TABLES parameter to the command. For example:
1
TABLES=table_name


Replace 'table_name' with the name of the table you want to import.

  1. Run the import command and wait for the process to complete. The Data Pump Import utility will import the specified table from the dump file into the Oracle database.
  2. Once the import is complete, you can verify that the table has been successfully imported by querying the table or checking the database schema.


Please note that the syntax and parameters may vary depending on the version of Oracle database you are using. It is recommended to refer to the Oracle documentation for more information on importing tables from dump files.
