Oracle Database Interview Question:

How To Export Several Tables Together?

Submitted by: Administrator

If you don't want to export the entire schema and only want to export several tables only, you can use the "expdp" command with the "TABLES" parameter as shown in the following tutorial exercise:

>cd oraclexeapporacleproduct10.2.0serverBIN

>expdp hr/globalguideline TABLES=employees,departments
DIRECTORY=hr_dump DUMPFILE=tables.dmp LOGFILE=tables.log

Starting "HR"."SYS_EXPORT_TABLE_01": hr/********
TABLES=employees,departments DIRECTORY=hr_dump
DUMPFILE=tables.dmp
LOGFILE=tables.log
