All,

I am trying to open another session using input parameters passed to the procedure. Can I open a session in a procedure and if so how do I stay in the opened session?
Is it possible at all?

I am placing the code that I used.

Appreciate any ideas or suggestions.
Radhika.

create or replace procedure open_session(userid_in in varchar2,

                                          password_in in  varchar2)

connect_string varchar2(14);
      sql_stmt varchar2(2000);
     curr_user varchar2(20);

cursor_handle integer;

feedback_v integer;
begin
connect_string := 'xxx_database'; --database connect string.

/* create a cursor to user fo the dynamic sql */
cursor_handle := DBMS_SQL.OPEN_CURSOR;

/*construct the sql statement and parse it. */
sql_stmt := 'connect
'||userid_in||'/'||password_in||'@'||connect_string||';'; dbms_output.put_line('Constructed SqlStmt is: '||sql_stmt);

/* parse the sql statment */

DBMS_SQL.PARSE
(cursor_handle, sql_stmt, DBMS_SQL.NATIVE);

/* execute the sql statement */

feedback_v := DBMS_SQL.EXECUTE(cursor_handle);

/* check to see which user is connected */
select user

into curr_user
from dual;
dbms_output.put_line(curr_user);
dbms_output.put_line('Feedback'||feedback_v);

/* close the cursor */

DBMS_SQL.CLOSE_CURSOR(cursor_handle);

EXCEPTION
  WHEN OTHERS
  THEN
   /* close cursor on failure */
   DBMS_SQL.CLOSE_CURSOR(cursor_handle);

end validate_user;
