Expression Evaluator with TWO csv files

Hi Chad,

 

 

Do both attributes hav the same name? this can be a reason for failure.

 

Another misconception is that if you direct two data streams into the expression evaluatoer, you think you can use values form both streams.

 

You can merge both datasets into 1 stream (prefixing one of them) and input that into the expression evaluator. The uncoditional feature merger from the FME store  can help you with that.

 

 

Hope this helps.

They have different names one is col3 and one is col4. I came to the conclusion the evaluator could only use one stream and now I am trying to combine them somehow. The merger you are talking about is different than the one in desktop?

yes it will merge everything with everything, see documentation.

 

You can also just create an attribute (say myatt) with value 1, on both dataset and use that on the regular merger

Hi,

 

 

Additional information: new regular FeatureMerger of FME 2013 SP2 can be used to unconditional merge without adding new attribute to input features. That is to say, we can specify a constant value to the "Join On" parameters for both of Reaquester and Supplier.

 

New FeatureMerger has been improved in many respects :-)
