if we hav 10 records in a file, can we get first record from
it by using Aggregator with out using Groupby Port in it?If
Yes..let me know the answer plz!!!
Answer Posted / jhilam roy
Simple answer: NO, provided, only the Aggregator
transformation is used.
In an Aggregator transformation, if no port is selected as
Group By, then by default, the PowerCenter Sever returns the
very last row of the input record set, definitely not the
first one.
It scans sequentially starting from the first port of the
input set and continues till the last port is hit. If it
fails to find any port designated as Group By, the default
nature is to return the last record of the input record set
to the downstream transformation or target.
Any updation is appreciated.
