small modification to the above ans:
SRC---->Transformer--->TGT
we do the 'HASH' partitioning on Dept_No.
SetNull value to the Stage variable----->SV_List
In the transformer stage variables:
SV_List :',' : Employee_Name ----->SV_List (Concatenating Employee
Names)
In the Column Derivation:
TRIM(SV_list, ',' , 'L')------->Employee_Name

Answer / srinivas
By using the stage variables in transformer we can do this.
Before going to use transformer sort the data based on two columns.Order should be like below
Deptno Empname
10 A
10 B
SO ON...
After that in transformer take 3 stage varibles
stg1--->map the sorted Deptcolumn
stg2---> DSLink2.empname:',' (map the empname column and concatenate comma operator)
Stg2--->stg3:stg2 (concatenate first two staging varibles)
Then
In derivation of employee_list column (In transformer)
use below function
TRIM(stg3,',','T')---->employee_list (column derviarion)
It will gives you as expected result.
Thanks
