exporting some table table from oracle DB to Mysql DB I need to export some of the tables from Oracle DB to Mysql DB..i dont have any previous experience of export and Import. Could some please tell me how to do that ?
Oracle export tools use their own proprietary format that MySQL can not process.

Just unload your data to CSV or insert statements with SQL Developer, then load the result in MySQL
