Answer / murthy
I'm not expert , actually i'm a new commer on datastage
i think this problem can be achieved by using pivot stage
because it converts the multiple columns data format in to
the multiple rows format, so i think it will be useful for u
thanks

Hi,
according to my idea, take 3 different groups in the
normalizer transformation like....
1. stud_id studname
------- --------
1 Ramesh
2 Himesh
3 Mahesh
2. Sub_id Subname
------- -------
10 ENG
20 MAT
30 ART
3. sub_id stud_id marks
------ ------- -----
1 10 68
1 20 82
1 30 78
2 10 73
2 20 87
2 30 89
3 10 81
3 20 79
3 30 64
make sure that all these 3 groups have proper relationship
with each other.
finally map the appropriate fields to the target.
I'm not exactly sure about this answer but i would be
thankfull for any suggestions.
have a nice day. Kishore.
