we r using aggregator with out using groupby?
Answer Posted / srikanth nallapati
if we are not using group by also u get the result from agg
traceformation but u get only one one total column result
Ex:deptno sal
10 1000
20 3000
30 4000
10 5000
in aggr trance i am not use group by but i create one new
column like sum_of_sal here logic implementation is sum(sal)
this sum sal is linked with target table then u get result
as like above description.... if u try to send more then
one column from this aggre tranc means it's fail..
i think it's work....

Enlist the tasks for which source qualifier transformation is used.
Hi, I saw one mapping implemented by my seniors . In Expression transformation they implemented following logic. That is iif(is_date(in_UC_DATINV,'YYYYMMDD'),to_date(in_UC_DATINV,'Y YYYMMDD'),'Inventory Date is either invalid or null') Inventory_Date is validated only for is_date() But not validated for notisnull() . But error says “ either invalid or null “ why? Whether is_date() also check for not isnull() ? or in this logic something is different ? Please answer me . Advance thanks
