Answer / shekharjchandra

Please frame question correctly ...
Seems u r question is something like below

<<label>>
DECLARE
a NUMBER := 10 ;
b NUMBER := 20;
BEGIN
-- Some statement
NULL ;
DECLARE
a NUMBER := 30 ;
c NUMBER := 40 ;
BEGIN
-- Some statement
NULL ;
END ;
END ;
/


Obviously the value of a in nested block will be 30 (Check this topic in Scope and visibility in Oracle documentation)
