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)

Hi Guys, I have a situation where I need to access the column values from rowtype variable. However, the column names are dynamic. below is sample code: declare Cursor c1 is select * from emp; Cursor c2 is select column_name from xyztable; v_c2 c2%rowtype; v_str varchar2 v_value varchar2(200); begin for rec in c1 loop open c2;---this cursor has column names like EMPLOYEE_ID, FIRST_NAME, LAST_NAME etc. loop fetch c2 into v_c2; exit when c2%notfound; /* now lets say i want to access value of LAST_NAME from cursor c1, so I am writing below code, however it does not work as expected */ v_str:= 'rec.'|| v_c2.column_name; -- this will give me string like "rec.EMPLOYEE_ID" v_value:=v_str; end loop; end loop; end; / Plz help ASAP.Thanks.
