Having NULL as value in the attribute

Hello team,

I have an attribute which contains the data itself as NULL. Now I need to pass this value.

Can you please suggest the function

iif(column_name= NULL, false, true) – This will give the output in a perfect way for all the BLANK values, similarly I need for NULL as a value.

Best regards,

Hello Tejesh,
Could you please share the exact use case which you are having? What data source are you using? Is it a text file, database, or some other input? Where do you need to pass this value? How the expected output should look like?
Kind regards,
