If the object already exists, skip it and execute the next one), append (append existing table data without affecting the original row ), truncate (delete existing table rows and save all data) and replace (delete existing tables, create new tables, and save data)

impdp mia/mia directory=dmp_dir dumpfile=test.dmp table_exists_action=skip

impdp mia/mia directory=dmp_dir dumpfile=test.dmp table_exists_action=append

impdp mia/mia directory=dmp_dir dumpfile=test.dmp table_exists_action=truncate

impdp mia/mia directory=dmp_dir dumpfile=test.dmp table_exists_action=replace

Import the specified table, modify the table space, and modify the user. Parameter: remap_schema = original user: target user, remap_tablespace = (original table space: target table space). You can use ", "Split, such as (a: B, c: d)

impdp mia/mia DIRECTORY=DMP_DIR dumpfile=test.dmp  logfile=impdp_index.log remap_schema=uibs:mia  remap_tablespace=\(IBSDATA:MIADATA\)
