程序给的代码是用的SQL2000 我安装的是SQL2005 1433端口已经打开
从网站上下载的jar包已经导入 也修改了连接语句
SQL2000
String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=db_CityInfo";
SQL2005
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String dbURL = "jdbc:sqlserver://localhost:1433; DatabaseName=db_CityInfo";
但是运行时报错

求解释 是不是数据库连接部分还需要更改
