How to see result set form pl/sql block

I am trying to run pl/sql using ref cursor as out parameter (for result set) result set back.
I do not know How to see my result set using pl/sql block.
Does any body has any idea ?
Also can any body tell me how can I use %rowcount for check number of rows in result stat. It's select statment

Try

set serveroutput on;

I can not see using server output on. it's a multiple data

set serveroutput on on SQL prompt,

In PL/SQL Code, use package,

DBMS_OUTPUT

To see the output, U can use the function,

DBMS_OUTPUT.putline(' Your Message '||VariableName);

It is a multi raw result set. can not be stored in a variable. it is selected using opening ref cursor.
It can not been seen through dbms_output

Hi,
