Hi Suneel
You can use several methods to ensure that you do not insert duplicate rows:
u2022 Design the data flow to completely replace the target table during each
execution
This technique can be optimal when the changes to the target table are
numerous compared to the size of the table. You can use tuning
techniques such as bulk loading options to improve overall performance.
u2022 Set the auto correct load option for the target table
The auto correct load option checks the target table for existing rows
before adding new rows to the table. Using the auto correct load option,
however, can needlessly slow jobs executed in non-recovery mode.
Consider this technique when the target table is large and the changes
to the table are relatively few.
u2022 Include a SQL command to execute before the table loads
Preload SQL commands can remove partial database updates that occur
during incomplete execution of a step in a job. Typically, the preload SQL
command deletes rows based on a variable that is set before the partial
insertion step began.
