Answer / ankit gosain

Hi All,

Create a job design like below:

SeqFile--->SortStage--->Transformer--->RemoveDup--->SeqFile

Steps:
-----
1. At sort stage, take sort key = Company and sort key mode
= Don't sort (Previously Grouped) & take a
CreateClusterKeyChange column.

2. At Transformer Stage, create two stage variables:
temp of integer type with 0 as default,
temp1 of varchar type.
now, write in their derivation:
if clusterKeyChange=1 then 1 else temp+1----temp
if clusterKeyChange=1 then Location else temp1:',':Location-
---temp1
Create one o/p column (say count).
Now derive the o/p derivation columns as:
Company--------Company
temp1----------Location
temp-----------Count

3. At remove duplicate stage, take key=Company and
Duplicate to retain = Last
now just drag and drop the i/p columns to o/p derivation
& you will get the desired result.

For further queries, mail me on ankitgosain@gmail.com

Cheers,
Ankit :)

Answer / subhash

what Ankit explained is correct. but small correction:
as per abouve explanation we get o/p location as below:
LOCATION
,chennai,hydrabad,pune,banglore
,chennai,mumbai,bangloore
,hydrabad,chennai
,pune

So, we need to do LTRIM/TRIM Function in devivation of the
column:
TRIM(temp1,',')---------->Location

then we get desired output.

Answer / raj

There are two requirements here
1. Counting
2. Converting rows to columns

Here is the design of the job
Source -> Pivot(Vertical) -> Transformer -> Destination

Pivot:
1. Use vertical pivot.
2. Mention Company as Group by column and Location as pivot. In the aggregate column choose count

Transformer:
1. Above pivoting gives locations in different columns. Use transformer to concatenate these columns using : operator
