try
{

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

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'");
//out.println("connection success");

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

con.close();

您需要打印它

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