Connection con = DriverManager.getConnection("jdbc:odbc:ge","ge","ge"); 
Statement st=con.createStatement(); 
//String sql=("select count(*) from employees where status='Present'"); 
//out.println("Number of present days"+sql); 
ResultSet rs = null; 

rs = st.executeQuery("select count(*) from employees where status='Present'");

st.executeQuery("select count(*) from employees where status='Present'"); 

con.close();

您需要打印

int rowcount = resultSet.getInt(1); 
out.println(i);
