Answer / babu

Sorry Shankar,

small mistake in your logic,

Exp Trans:
ID (I/O)
NAME (I)
V_NAME=IIF(ID=V_ID,V_NAME||'+'||NAME,NAME) (V)
V_ID=ID (V)
O_NAME=V_NAME (O)

=============
remaining is same.

Answer / souvik

We need to have a Lookup with a Dynamic Cache, a Router, an Expression and then an Update Strategy..... The Lookup will be on the Target Table..... So when the ID is coming for the first time, it wont found any data on the lookup table.... This can be directed for Insertion to the Target Table via a Router.... Then when the same ID is coming for the second time, it will Lookup on the Target Table and will found that the row with the ID exists.... Hence both the columns from the source table and both the columns from the Lookup are taken forward into the Router and then to an Expression Transformation where the second port is Concatenated. Then the ID port and this port is taken to the Update Strategy transformation for Update...
