Cascading Lookups

Post by sdfasih »

Hi,
I was wondering if there is a way to do this.I would like to know if I have three Hash Files each having a single column say Col1.
Hash1 Col1 is Source to transformer stage
Hash2 Col1 is lookup to transformer stage
Hash3 Col1 is lookup to transformer stage.
I can do a lookup Hash1 Col1 with Hash2 Col1.Now can I do a lookup Hash2 Col1 with Hash3 Col1?
Thanx in advance.

I think it is possible but you will see the key in red. I would rather do it in two transformers. Test it out and let us know.

The job type was marked as server and hence I went ahead with it. O well.
