急求cannot be resolved怎么改呀?
import java.sql.*;
public class Ss {
public static void main(String[] args) {
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");}
catch(ClassNotFoundException e){}
Connection con=DriverManager.getConnection("jdbc:odbc:ee");
try{Statement sql=con.createStatement();}
catch(SQLException e){}
ResultSet rs=sql.executeQuery("select * from cc");
}
}

嗯.这个问题很有深度,经过我代码粘贴和MyEclipse测试,终于知道什么问题了.主要是ResultSet rs=sql.executeQuery("select * from cc");中sql没有定义,因为sql在try,catch范围内,需要把这条与句改为：
try{
Connection con=DriverManager.getConnection("jdbc:odbc:ee");
Statement sql=con.createStatement();
ResultSet rs=sql.executeQuery("select * from cc");}
catch(SQLException e){
}
