Is this possible to implement pre & post Sql on Source table and Target table in talend with main flow.
I'm not entirely sure whether this is the response you are after, but Talend provides the tPreJob and tPosJob components for processes that need to take place before and after the main flow. The tPreJob will ensure that whatever is connected is run before the main flow. The tPostJob is a bit more special since this will always run at the end, even if there has been an error in the main flow. This can be REALLY useful.
hii yes its an alternative solution. but i want to perform presql on target table with main flow.
