InterviewSolution

1.	What is joining a table to itself called?(a) COMPLETE(b) SELF(c) OBSOLETE(d) CROSS
Answer» Right choice is (b) SELF To explain I would say: Joining a table to itself in a database is called ‘self-join’. When a self-join is being performed, the table is being used multiple times within the query and a table name qualifier is unnecessary.
