addNullQuery() and addNotNullQuery()
Both addNullQuery() and addNotNullQuery() accept a single argument; a string, indicating which field should be checked.
When addNullQuery() is called on a GlideRecord object, it adds a condition to your query, stating that the field passed into the method call must be null (empty).
On the other hand, when the addNotNullQuery() method is called with a field name as an argument, a condition is added to your query stating just the opposite - that the field must contain a value - any value. It must be NotNull.
