Schema name as Parameter

Question

Hi,
I have a requirement where i need to pass the schema names during run time for a cursor.
Is there any way I can do it for an existing cursor?
For example, the idea is to pass the schema name as a parameter as mentioned below.we have set of programs which are written already and the current requreiments is to change the schema name alone as a parameter.
Please advice.
Example:
CREATE OR REPLACE PROCEDURE proc_TEST (SRC_SCH VARCHAR2)
IS
CURSOR c_Account(SRC_SCH VARCHAR2) IS
SELECT *
FROM &SRC_SCH.T2ACCOUNTS;
fl_Success Boolean;
BEGIN
END proc_TEST;

You need to use dynamic SQL.
SQL> conn thomas2/thomas@ora9204
Connected.
SQL> create table test(id number);
&nbsp
Table created.
&nbsp
SQL> insert into test values(2);
&nbsp
1 row created.
&nbsp
SQL> grant select on test to scott;
&nbsp
Grant succeeded.
&nbsp
SQL> conn thomas1/thomas@ora9204
Connected.
SQL> create table test(id number);
&nbsp
Table created.
&nbsp
SQL> insert into test values(1);
&nbsp
1 row created.
&nbsp
SQL> grant select on test to scott;
&nbsp
Grant succeeded.
&nbsp
SQL> conn scott/tiger@ora9204
Connected.
SQL> create or replace procedure get_id(sch varchar2)
  2  is
  3   id number;
  4   cur sys_refcursor;
  5  begin
  6   open cur for 'select id from ' || sch || '.test';
  7   loop
  8    fetch cur into id;
  9    exit when cur%notfound;
10    dbms_output.put_line(id);
11   end loop;
12   close cur;
13  end;
14  /
&nbsp
Procedure created.
&nbsp
SQL> set serveroutput on
SQL> exec get_id('thomas1');
1
&nbsp
PL/SQL procedure successfully completed.
&nbsp
SQL> exec get_id('thomas2');
2
&nbsp
PL/SQL procedure successfully completed.
&nbspRgds.
