filter tool: syntax 1 ==1

[dileepkorade]

Hello everyone,

I am understanding and monitoring Alteryx workflow.

In one of the workflows, I have seen 1==1 syntax under custom filter in filter tool. 

Can anyone please help me to understand this syntax?

is a generic filter for tests. this option will always pass to the true channel,
if you have something in the false channel for testing, just replace it with 1==0.

Hi @dileepkorade 

Actually, I write it like 1 = 1 because that's how we write equality conditions, with a single = sign, I tried two equal signs and it worked 😮  here the explanation Basic Filter Expression seems wrong 

Well back to your question, sometimes we write workflows implementing filters as per requirements, but while testing and working with stakeholders a decision is taken that that particular filter rule is no longer needed, so instead of deleting the filter, the developer write the condition 1 equal 1 (either 1 = 1 or 1 == 1). The adventage of replacing the condition with 1 = 1 is diminishing the impact of the change and avoiding rigurous testing.

Hope this helps,

Arnaldo
