Use the Expression Transformation to Concatenate all the desired columns and map it with target.

Suppose your source data data is like below:

id val
1  A
1  B
1  C

and your desired output is like :


If I understood your problem correctly, Then use expression and aggregator transaformation. In expression transformation, concat val column with the help of using variable port like below.

id --- I/O port
val -- I/O port
v_prev_id = id  --- Variable port
v_val = iif(v_prev_id = v_curr_id, v_val || val, val)  --- Variable port
v_curr_id = id  --- Variable port
o_val = v_val -- output port

data after expression transformstion would be like below:

id o_val
1   A
1   AB
1   ABC

Take an Aggregarator after expression , and chhose id as group by. and pass id and o_val port to your target. It will give your desired output.

If your data is like (1, A, B, C) and your desired output is (1,ABC) Then what Shatark sir suggested is correct answer.

Described in the best way.
I have one column that consist of 3 rows i.e (ABC). This data splitted to 3 columns
input       output
c1           c1   c2   c3
a             a     b     c

I think Nandan has described the same.
If you still have some query please ask the separate question as this is very old thread.

I have data in table A as below

Assetid   attribute   value
    1546    Ins_date   05062011
    1546    status     active
    1546    X          10.4567
    1546    Y          27.56
    1546    size       17
    675     X          4.778
    675     Y          53.676
    675     depth      5
    675     st_date    06092010

I have data as above in table A. This table has many Assetids 1546,675,....etc. attributes might vary for assets.

I want output as below:

assetid  ins_date  status  X        Y       Size  depth  st_date
1546     05062011  active  10.4567  27.56   17    null   null
675      null      null    4.778    53.676  null  5      06092010

I have created Stored procedure, then called in Informatica to achieve this output. However, since i have large volume of data, it is taking much time to load.

Please suggest me other easy and best way to load it.
