CG/SQL Demonstration 5: "Select *" and JSON Schema Discussion
In the first part of this video we first review some of the consequences of the schema management choices we made. In particular why is it safe to use "select *" and what is the compiler doing to make it so? How do inserts work in the face of deleted columns? What about the other constructs that assume table shape?
In the second part we briefly go over the JSON output of the system and its uses. For more details see see the documentation at
