IF your SELECT returns more than one row, you won't be able to use the SELECT INTO synthax.

You will need to build a loop to navigate through the resulte set:

Adam demonstrated how you would use an explicit cursor and a bulk collect loop. I will show how you can build the simplest loop possible (implicit cursor, doesn't need a DECLARE section):

BEGIN
   FOR c_emp IN (SELECT * 
                   FROM Employee 
                  WHERE Salary > 10) LOOP
      /* do something with each row, for example:*/
      UPDATE foo SET bar = bar + c_emp.salary WHERE id = c_emp.id;
   END LOOP;
END;
