Hi,

Whats the correct syntax to use when trying to return results where two fields DO NOT match?

Trying the following, but not within any great success;

| where NOT match(field A, field B)

Thanks.

There are lots of ways to solve this. I might go with something like:

| makeresults 
| eval fieldA="12345" 
| eval fieldB="1234" 
| eval DoTheyMatch=case(
    fieldA = fieldB,"TheyMatch",
    1==1, "TheyDoNotMatch"
    ) 
| where DoTheyMatch="TheyDoNotMatch"

To go to the docs, be aware of the following background information:
