Answer Posted / akila ramu
DB--->Transformer--->Output File
Sample data propagation through these stages:
In table->DB stage--->Tfm----->outputfile
101 0---->100 0 2 2-->100 0
100 0---->101 0 2 1-->100 0
101 1---->101 1 2 1
100 0
DB: Use the bvelow query in this stage
select emp_id, ind, count(emp_id) c1, count(emp_id ind) c2
from table_name
group by emp_id, ind
order by emp_id, ind
So similar empid-ind are grouped and the count of each
empid-ind pair is also sent in a seperate column c2. The
count of each emp_id is sent in c1.
Tfm: Output link Contraint:c1=c2
Looping contraint: @ITERATION<=c2
Looping variables: l_empid=emp_id
l_ind=ind
Pass these two looping variables as the emp_id and the ind
to the output file.
