In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements.
In declare part, we declare variables and between begin and end part, we perform the operations.
Basic structure of pl/sql block
declare -- declare all the variables begin -- for start block -- make a program here end -- for end block
