Finding Null Values
OP: September 19, 2016, 11:00:00 PM
Having difficulty filtering on NULL values.  Inputting any numerical value in the “Months Since Last Delinquency” range fields excludes all returns without a value so trying to create a custom query.   

I know the language is not quite SQL but I cannot find the right syntax to make the query work.  I am attempting to filter only loans with a null value in the field mthsSinceLastDelinq. 

Tried several variations in the "Custom Filter - Experts Only" field including:
   mthsSinceLastDelinq isnull
   mthsSinceLastDelinq is null

PLS Version 7.904

Any suggestions appreciated.

Thanks, Mouser
