First in the pre_session command task remove the duplicates
using the following
cut -d "," -f2 filename|uniq
Now in the file you will have
3000
4000
5000
2700
4500
now after source qualifier keep a expression and generate
the sequence.
Hope it clarifies

Answer / jayachandra
One solution is use distinct key word on source qualfier as
suppose your table name is emp than on emp_sq
the query is
select emp_no,distinct sal from emp;
2nd sol is make an aggregator transformation here make a
coun()on sal port with group by then put filter
transformation with condition count(sal)=1
