Hi,
I want to know how to load 2 records in to the target from single source record.
Eg.
Source columns
A B C D E
Source records
123 AAA 2354 4656 bbb
234 BBC 8762 9876 ddd
Target columns
A B C D E
Target Records
123 2354 4656 bbb
123 AAA 2354 4656 bbb
234 8762 9876 ddd
234 BBC 8762 9876 ddd

In the target I need to load two records for ever source record.
First record of the every target record for the Value A, column B value should be NULL.
Second record of the every target record for the value A is a direct pass through, ie it looks exactly same as source record.
Please help me in writing the above logic.
Thanks in advance

a transformer with 2 outputs will do the job, selecting the right metadata...

Hi All,
Thanks ucf007,

I want the out put in single target file with two records with the above logic.
for one source record i need to load two records with the above logic in the same target file.

Thanks in Advance

You got a right answer, a transformer with 2 outputs will do the job, selecting the right metadata...
Use 2 links writing to the same dataset

There are other solutions, but the Transformer stage with two outputs will be the easiest to implement, and is correct. Simply map the columns required on each output using drag and drop. You could do the same with a Copy stage with two outputs.

If you are writing to a sequential output file you can funnel both your output links back together again. They should have the same column metadata.

looking at your example, you want to:
1. read source fields: A B C D E
2. write to
A C D E
A B C D E

I'd simply read the file twice (2 output links) --> hash (to enable multiple write at the same time)

Hi,
what happens if two individual seq stages with append mode...

Nothing, except maybe an abort.

Operating system rules prohibit more than one writer to a sequential file.

Assuming you have columns A B C D E on both transformer output links where column B is null on the first link you can use the funnel stage to turn it back into a single stream and write it to a sequential file.

Hello All,
Thanks to eveybody who replied my question.

I created two output's where in one link i gave column B as null,
Using funnel stage I created the sequential file with desired output.


Thanks and Regards
