Answers were Sorted based on User's Feedback



we r using aggregator with out using groupby?..

Answer / satya

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.

Answer / amedela chandra sekhar

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.
