%TYPE provides the data type of a variable or a database
column to that variable.
%ROWTYPE provides the record type that represents a entire
row of a table or view or columns selected in the cursor.
The advantages are :
I. Need not know about variable's data type.
II.If the database definition of a column in a table
changes, the data type of a variable changes accordingly.
