2)i have number of records in my sourse, but iwant to
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

HI VENKATESH,
YOUR ABOVE ANSWER IS NOT CORRECTLY WORKING IN MY
SYSTEM. SO PLEASE EXECUTE THE ABOVE SOLUTION ONCE AGAIN LOAD
IT. AS PER MY KNOWLEDGE WE CAN CREATE A MAPPING VARIABLE AS
$$SEQ,DATA TYPE IS INTEGER AND SELECT AGGREGATION COLOUMN IS
COUNT. USING EXP TRANSFORMATION SETCOUNTVARIABLE($$SEQ). IT
WILL WORK CORRECTLY.
