Filter Transformation

Mohamed Mohamed 66 Reputation points

Can I please post this question again!

In ADF data mapping, I have the column SensitiveRecord with the possibilities (Yes - No - Allow - Null).

I want to filter out the "Yes".

I used the expression SensitiveRecord != "Yes".

The Problem: It only retrieved the "No" rows, while i was expecting "No", "Allow" and Null!

Could you please help where I went wrong! Thanks

    I had been testing at my end - I did find the Null values were not getting filtered. I used the below expression to handle that as well and it proved working at my end.

    (isNull(SensitiveColumn) || SensitiveColumn != 'Yes')  

    Output :
