Hello,

I have a table with 4 Header:
A B C D
I need to show A C D column if B is null and B C D column if A is null, how to do that?

Search:
some selection | table A B C D

Not really sure that it fits with your requirements and underlying events, but eval's coalesce function may be the thing you're looking for. It will assign the new field the first non-null value of the fields listed.

Event1: A= B=2 C=3 D=4
Event2: A=1 B= C=3 D=4

search:

... | eval First = coalesce(A,B) | table First C D 

result:

First   C   D
    2   3   4
    1   3   4

Hope this helps,

Kristian
