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
Sorry guys...correction...If you do not select any group by
port in an Aggregator transformation and also want the first
record of any input record set, then, simply use the FIRST
function with no group by ports selected. Because, if there
is no group by ports selected, by default, FIRST treats all
rows as one group, returning one value. However, make sure
that the first record is not NULL. If a value is NULL, FIRST
ignores the row.
