How can I identify the duplicate rows in a seq or comma delimited file?the case is...> the source has 4 values like, agent id, agent name, etc... our requirement is that the ID shouldn't be repeated. so how can i identify the duplicate rows , set a flag and send the rejects to the specified reject file? the source systems data is directly given to us. tha's why we are getting these duplicates.if it has a primary key set up already then it would have been very easy.thanks in advance.
