Java: Inheritance Test

Invalid Code

Valid Code

SQL: Tests with Null

   /** Exec: https://jdoodle.com/a/1sJB */
   create table sample(id int not null, name varchar);

   insert into sample values(0, "Clark");

   insert into sample values(4, NULL);
   insert into sample values(5, "Tony");

   insert into sample values(7, "Peter");

   select * from sample where name is null;    /* 2 Lines returned - id 2 and 4 */
   select * from sample where name = "";       /* 1 Line returned  - id 2 */
   select * from sample where name = null;     /* 0 Lines returned */
