Using fillnull for multiple fields?

[dannyzen]

What is the best way to use fillnull for multiple fields? What is the best way to avoid it working for only the first field?
Some examples are:
| fillnull value=NULL field1 field2 field3
| fillnull value=NULL field1 | fillnull value=NULL field2 | fillnull value=NULL field3

Thank You

Thank you
I will group the fields as field1 field2 field3

If wanted to substitute values for null values in all the fields
you can specify |fillnull

@dannyzen, I would choose the following above adding separate pipes for each fillnull. Separate pipe means entire record will be used again for the 2nd fillnull and so on. The fillnull command being a streaming command it would make sense to call in a single place.

| fillnull value=NULL field1 field2 field3

However, you can definitely test the actual performance using Job Inspector for both the compare and see the response time for yourself.
