HERE IS Mine answer an alternative without pivot stage:
SRC-->TX1-->TX2-->RemDup-->TRG
from SRC send data to TX1 with RowNumCol
then Data :
col1 Row_Num
c1 0
c2 1
c3 2
c4 3
c4 4
c5 5
c6 6
c7 7
Now in Tx1 take stage variable sv1 and using Row_Num field
give condition as : If Row_Num >=0 And Row_Num <3 Then 1
Else If Row_Num >= 3 And Row_Num <6 Then 2 Else 3
o/p :
col1 col2
c1 1
c2 1
c3 1
c4 2
c4 2
c5 2
c6 3
c7 3
(If you don't know Vertical Pivoting then alternatively we
use another Transformer and Remove Duplicate stages to get
our result)
now at Tx2 we take Three Stage Variables sv1 sv2 sv3 all are
varchar
now we give proper conditions to concatinate input using col2.
Stage variables: Assignment
col2---sv1
If sv1 <> sv3 Then col2 Else sv2 : ',' : col2 --- sv2
col2---sv3
Now at this level u should get o/p as:
newcol1 newcol2
1 c1
1 c1,c2
1 c1,c2,c3
2 c4
2 c4,c4
2 c4,c4,c5
3 c6
3 c6,c7
Finally use Rem Duplicates by selecting
Duplicates to Retain : Last
o/p
1 c1,c2,c3
2 c4,c4,c5
3 c6,c7
(Just in case if you dont want 1st column just drop it using
modify stage or copy stage.)
Yeah i know its a lengthy way and it sucks,
out of curiosity did it mannnnn.
Better use Pivot stage -a wonderful stage
