Data massage in ODI

Question

Hi,
I need to select some data from the source table and concatenate into 1 string and insert into another table as follows:
ID SEQ VALUE
1 1 ABC
1 2 EFG
1 3 HIJ
2 1 ABC
and the result table will be:
ID VALUE
1 ABC:EFG:HIJ
2 ABC:....
I'd create a procedure with 2 cursor loop to concat. the data and insert into my target table.
I just wonder whether there is any 'ODI' way to handle this case?
Thanks a lot!!

If you know the possible max value for the sequence you can do something easy with ODI.
If your sequence max value is 3 like in your example.
In source you can put 3 times your file
for each one set a filter on sequence=1 for the first, sequence=2 for the 2nd,...
then you can join them in outer join with ID=ID
you will now have, following your example, 2 records
1,ABC,EFG,HIJ
2,ABC,NULL,NULL
In your target datastore you can easily mange the NULL value.
If you don't know how many sequence you will have for one ID or if the max value is too big I advice you to do a script and to paste it in an ODI procedure.
