SELECT Date_Of_Birth AS DOB, Country as Country from Details where Gender='Male' and zipcode = 'XXXXXX' In microflow Execute query is implemented and the query above is getting used. Problem statement For some records the Date_of_Birth is having null/empty value, due to this reason the Execute query never getting executed. Is there any way I can use NVL function in this query to make it work. Thanks, Sudhansu
