Execute SQL looking for Empty and not Empty

Hello, What's the proper format to when looking for empty and not empty information?

Here are two examples from the  FileMaker16 SQL Reference document (which should always be the first place to look): 

SELECT Sales_Data.Amount FROM Sales_Data WHERE Sales_Data.Amount IS NULL

SELECT Sales_Data.Amount FROM Sales_Data WHERE Sales_Data.Amount IS NOT NULL
