Hi experts,
3 months back i have taken full export from my production database which is runiing IBM-AIX server 5.3 and import on windows server which is for test purpose.but my manager said he needs the updated data on my windows server, but i take the latest export from prod database and import on test database,does duplicate data will come if primary key doesn't exist, so i dont want to delete all test database users it takes long time for me to do.so please can any one have idea about having latets data on my test database from prodution database without deleting users or is there any parameter to specify while import.quick response will be higly appreciated.thanks a lot in advance.
