Using %TYPEThe %TYPE attribute gives the datatype of a variable or the database column. In the example below, the %TYPE gives the datatype of a variable:credit REAL(7,2);debit credit%TYPE;The Variables declared using %TYPE is treated such as those declared using a datatype specifier. For example, given the earlier declarations, the PL/SQL treats debit such as REAL (7, 2) variable. The later example shows that a %TYPE declaration can involve an initialization clause:balance NUMBER(7,2);minimum_balance balance%TYPE := 10.00;The %TYPE attribute is mainly useful when declaring a variable which refer to a database columns.

Firstly, you do not require knowing the exact datatype of dname. Secondly, when the database definition of the dname changes, the datatype of my_dname change accordingly at the run time.
