Hello,
I have defined a sys_refcursor in my procedure. Basically i dont want to give sys_refcusor instead i have to define a type and use here. Can someone tell me how do i replace sys_refcursor and use a type here? what is the alternate changes i can do instead of using sys_refcusor.

Simple answer - not possible. Oracle does not know that these tables have the same physical structure. Oracle cannot trust you/the DBA/whoever to 100% guarantee that these tables will always have the same physical structure.
Thus Oracle does not care about a statement like "STRUCTURE OF EMPLOYEE TABLE IS SAME everywhere".
The complex answer - it is possible. One method that comes to mind is to use a single "template" for all tables. Weak cursors can then be used, but via the SELECT's projection you can ensure that the same template is used. In your code, you thus deal with this template (and its definition) and not with the table structure.
Basic example:
SQL> create or replace type TEmployee as object
2 (
3 empid number,
4 deptid number
5 );
6 /
Type created.
SQL>
SQL>
SQL> create table foo1 of TEmployee;
Table created.
SQL> create table foo2 of TEmployee;
Table created.
SQL>
SQL> insert into foo1 values( 1, 1 );
1 row created.
SQL> insert into foo1 values( 2, 1 );
1 row created.
SQL> insert into foo2 values( 3, 2 );
1 row created.
SQL> commit;
Commit complete.
SQL>
SQL>
SQL> create or replace procedure ListEmp( tablename varchar2 ) is
2 cur SYS_REFCURSOR;
3 row TEmployee;
4 begin
5 open cur for 'select VALUE(e) from '||tablename||' e';
6 loop
7 fetch cur into row;
8 exit when cur%NOTFOUND;
9 DBMS_OUTPUT.put_line( row.empid||' '||row.deptid );
10 end loop;
11 close cur;
12 end;
13 /
Procedure created.
