public class EmployeeReader1 {
public static void main(String[] args) {
Connection connection = null;
try {
Class.forName
("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =
DriverManager.getConnection("jdbc:odbc:gowtham");
Statement st = con.createStatement

ResultSet rs = st.executeQuery
("select * from [Sheet1$]");

while(rs.next())
{
System.out.println
("USER ID:"+rs.getString("ID"));
}

rs.close();
st.close();
} catch (Exception ex) {
System.err.print("Exception: ");
