有什么JAVA免费IDE工具比较适合连接SQL数据库的

import java.sql.*;
public class conn
{
String sDBDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String sConnStr ="jdbc:odbc:dsnname";
Connection connect = null;
ResultSet rs = null;
public conn(){
try{
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e)
{
System.err.println("加载驱动错误");
}
}
public ResultSet executeQuery(String sql){
rs = null;
try{
connect = DriverManager.getConnection(sConnStr,"user","password");
Statement stmt = connect.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex)
{
System.err.println(ex.getMessage());}
return rs;
}
}

自己写代码连啊，
加个驱动就行了
