Chapter 7: Comments




        Examples



        Single-line comments


        Single line comments are preceded by --, and go until the end of the line:


         SELECT *
         FROM Employees -- this is a comment
         WHERE FName = 'John'


        Multi-line comments


        Multi-line code comments are wrapped in /* ... */:


         /* This query
            returns all employees */
         SELECT *
         FROM Employees


        It is also possible to insert such a comment into the middle of a line:


         SELECT /* all columns: */ *
         FROM Employees
