Subj:   Re: Couting duplicate rows thru multi load
 
From:   Jose Lora

You could use Fastload + INMOD (that will add a record id). This will give you the fastest loading time. Once in the database, use your SQL skills to locate / remove / etc. your duplicated records.

Now, there are some ways to avoid the INMOD, one is using an ETL tool that will allow you to read data from a file (or any other source), do transformations on the fly (calculate the new record id) and send the data directly to a Teradata Utility (streaming data to Fastload). The idea of course is avoid intermediate staging files outside Teradata and use parallelism to locate the duplicated rows.
