This document describes a DataStage job design to solve a scenario problem. The design includes: 1) A job with a sort stage to sort data based on a column in descending order. 2) A transformer stage that uses two stage variables to derive output. 3) An output file that sorts the data a second time in ascending order to produce the required output.

DataStage Scenario Problem ­­> DataStage Scenario ­ Problem3
Solution Design :
a) Job Design :
Below is the design which can achieve the output as we needed. Here, we are reading seq file as a input, then data is passing through a Sort and
Transformer stage to achieve the output.
b) Sort Stage Properties
in Sort stage, we will sort the data based on column “Sq” in descending order.

c) Transformer Stage Properties
Here, we took 2 stage variable : StageVar, StageVar1
and their derivations are ­
StageVar1 = StageVar
DSLink6.No = StageVar1
d) Output File
Before capturing the data into Sequential file. We will sort the data again in ascending order to get the output as we needed.

Hi,
If i try to generate auto id no. from ROW COLUMN NUMBER, it does not work. can someone please explain me why??
In such case, output is like as given below:­
sq no Next_val Row_Number
1 1000 0 0
2 2200 3030 1
3 3030 5600 2
4 5600 0 3

ROW COLUMN NUMBER is always start from '0' so get it correct no, you need to +1 each ROW COLUMN
NUMBER
