How does PL SQL handle BOOLEAN?
The Boolean data type in PL/SQL allows us to store True, False and Null values which help us in processing the logical states of a program unit. This data type is only available in PL/SQL and not in SQL, thus using Boolean values in an SQL statement has always been impossible until Oracle version 12cR1.
