For Datastage:
I/p........sort stage(create key change column for empno.)........ transformer ( here take stage variables count=0,sv1. For sv1 give derivation as(if keychange=1 then sv1=ename else sv1=sv1:',':ename) for count derivation (if keychange=1then count=1 else count=count +1).........remove duplicate stage(retain last)......o/p(desired result)

Seq stg------>Sort stg--------> Trnsfrm stg-------->Tgt
1. read data in seq file stage.
2. In sort stage enable key column change as true.
3. In transformer stage define stage variable SV1 (if DSLink5.keyChange = 1 then 1 else SV1 +1) and SV2 (if DSLink5.keyChange = 1 then DSLink5.ENAME else SV2 : ',' : DSLink5.ENAME
) . In output tab link ENO, SV2 -> Ename and SV1 -> Count. Add a constraint LastRowInGroup(DSLink5.ENO) and mark the ENO as key in input column.
