Answer / prakash chandran

Row To columns

Use Normalizer Transformation

Column To Rows
--------------

SOURCE
------
ENO COL_HDR COL_VAL
------------------------
1 ENAME PRAKASH
1 ESAL 35000
2 ENAME SREE
2 ESAL 25000

OUTPUT
------
ENO ENAME ESAL
1 PRAKASH 35000
2 SREE 25000

MAPPING LOGIC
--------------

SRC -----> AGG -----> TGT

Use First Function in Aggegrator to convert the Column to
rows

In Aggegrator, Create two output columns and write the
following expression

Port Name Expression
--------- ----------
O_ENAME FIRST(COL_VAL,COL_HDR='ENAME')
O_ESAL FIRST(COL_VAL,COL_HDR='ESAL')

Answer / ramarao

Hi Friends,

I think this possible by using source Qualifier ALSO.

The Senario is

Issue_id,Question,Answer
100,1,y
100,2,n
100,3,y
100,4,n

Target is issue_id,Answer1,Answer2,Answer3,Answer4
100, y,n,y,n

This can be Achived by using source Qualifier And joiners.
There is no need to use Normaliser.
