display first and last record only. how it is possible in
informatica.
ans:yes we get first and last record from table using
psuedo columns rownum and row id
i.e.,
in source qualifier t/r we caen create user defined queires
their type below query
select * from <table_name> where rownum=1 union select *
from <table_name> where rowid=(select max(rowid) from
<table_name>);
note:<table_name> is the name of the from which u want to
retrieve records
