transformer stage problem

[harikumar]

hi my source is like

empno,sal
1,2000
2,4000
4,5000
3,6000
5,4500
6,3400

target is like

empno,sal,sequnum
1,2000,2
2,4000,4
4,5000,6
3,6000,8
5,4500,10
6,3400,12

plz tell me the clear logic for generate evennumbers and oddnumbers using transformer stage(stagevariables)

[jsuryanathan]

Include the below code in transformation stage.
svSeqNum=@inrownum*2

For 1st record it will be 2
2nd row 4
3rd row 6

This is applicable to above data. You can change little as per your requirement

[anbu]

From your input sequnum=empno*2.

I dont see any odd numbers in your sequnum. Can you pl explain your requirement?

[kumar_s]

Both even and Odd in same output?
Looks like you need continues Sequence number.
If you want it seperately. Make the data to run in two node.
Make the Partition as Entire.
Run a SequenceGenerator.
One node will give you odd number and other will give you Even number.
For the same set of data.

hi for the same table one of the case i want to genrate oddnumers like

empno,sal,sequnum
1,2000,1
2,4000,3
4,5000,5
3,6000,7
5,4500,9
6,3400,11 like this please tell me the logic

You can use a similar formula like, sequnum=(empno*2) - 1

[ETLJOB]

sequnum=(empno*2) - 1

I don't think "sequnum=(empno*2) - 1" would solve the purpose for the given sample data, considering the fact that employee number is not in sorted order.

I believe "sequnum=(@inrownum*2)-1" would do for you.

"sequnum=(empno*2) - 1" will solve the problem whereas "sequnum=(@inrownum*2)-1" needs sorting for the data provided.
