If we use Aggregator without using group by option we will
get only one row from source. It is a default charater of
Informatica.
e.g If there are 20 rows in the source table and only
using SQ and followed by Aggregator then target table then
the target table will be populated by the last row coming
from teh source table.

If you are using groupby the integration service produces
one row for each group, if you do not use groupby the
integration service returns one row(last row) for all input
rows.

Answer / 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....

Answer / neeraj
By default aggregator does group by on each of the input
port so if 50 distinct rows are coming all will pass
through it..
