如果 你的 代码 没有错误
如果是 SQL user 登入 失败
如果 你是 用 Sql Server 2005 ,请往下看
提示你 几点：
首先 打开 你的 Sql 服务器,用 Windows 身份 登入
1.右键 当前 Sql 服务器--> 属性 --> 选择 安全性
服务器 登入身份：SQL SERVER 和 Windows 身份登入
登入审核：无
2.展开 服务器 下面 也有一个 安全 行,展开 --> 登入名 展开 -->选择 sa 右键 属性
常规：密码 设置 sa ,这个 随意.把 “强制密码” 的 勾 去掉
状态：授予 启用
这样 就可以 用 sa 连接 了
//
如果 还是 不行?
回去 检查 你的 代码 ba !
