The standard Is Null predicate is supported to test whether or not an expression has a SQL NULL value (i.e., is undefined in a particular row). The generated SQL takes the form expression IS NULL. When dragging an Is Null operator into a variable, the following tree element is created.

Variable Creation > Input > Variables: SQL Elements pane - Logical > Is Null

Columns and/or other expressions can be moved into the (empty) branches of the tree.

There are no special properties for the Is Null operator.
