Oracle Tutorials - Error: Imported Table Already Exists

(Continued from previous topic...)

What Happens If the Imported Table Already Exists?

If the import process tries to import a table that already exists, the Data Pump Import utility will return an error and skip this table. The following exercise shows you a good example:

>cd \oraclexe\app\oracle\product\10.2.0\server\BIN
>impdp hr/fyicenter TABLES=employees 
  DIRECTORY=hr_dump DUMPFILE=tables.dmp LOGFILE=tables.log

Master table "HR"."SYS_IMPORT_TABLE_01" loaded/unloaded
Starting "HR"."SYS_IMPORT_TABLE_01":  hr/** TABLES=employees
  DIRECTORY=hr_dump DUMPFILE=tables.dmp LOGFILE=tables.log
Processing object type TABLE_EXPORT/TABLE/TABLE
ORA-39151: Table "HR"."EMPLOYEES" exists. All dependent
  metadata and data will be skipped due to table_exists_action
  of skip
Processing object type TABLE_EXPORT/TABLE/TABLE_DATA
