 ## * operator
 
 The special operator * projects the entire item as is. When used, it must be the only projected field. A query like `SELECT * FROM Families f` is valid, but `SELECT VALUE * FROM Families f` and  `SELECT *, f.id FROM Families f` are not valid.
 
 ## ? and ?? operators
 
-You can use the Ternary (?) and Coalesce (??) operators to build conditional expressions, as in programming languages like C# and JavaScript.

 You can use the ? operator to construct new JSON properties on the fly. For example, the following query classifies grade levels into `elementary` or `other`:
