昨天用SQL语句建表的时候写了一段代码，对于代码的逻辑和内容我不太肯定对不对，反正是毫不犹豫的让它执行了，过程中出现好几个错误，当时没有太在意，想着大不了出错了再重写一个，结果……玩坏了，从昨天到现在十几个小时，SQL Server毫无商量的给我罢工了

昨天用SQL语句建表的时候写了一段代码，对于代码的逻辑和内容我不太肯定对不对，反正是毫不犹豫的让它执行了，过程中出现好几个错误，当时没有太在意，想着大不了出错了再重写一个，结果……玩坏了，从昨天到现在十几个小时，SQL Server毫无商量的给我罢工了！于是乎，漫长的“寻错”之路开始了。

先看下出错信息：

1.通过以往经验我先打开了SQL Server配置工具——>配置管理器，检查里边的协议是否开启，就在这时我又犯了一个错误。因为不知道那些协议到底是什么意思，索性干脆都启用了，结果可想而知，数据库依旧打不开(不过不影响继续找错……)，在后期找错误的过程中将这里的VIA更正为了禁用

2.然后又查看了TCP/IP属性——>TCP动态端口是否为空、TCP端口是否为1433，检查过后这里基本没有问题

3.上网找了一些相关的解决办法，是通过 计算机——>管理——>服务与应用程序 解决的。在这里关于SQL的服务又不知道是什么意思，索性第二次全部开启(后来上网查询过，这些是可以都开启的)，可是在启动下图中两个服务的时候又出现了问题：无法启动。

出错信息1)是因为在1.中没有禁用VIA所致。

出错信息2)是因为它与1)是依存关系，1)没开启它就开启不了。这个逻辑关系倒是简单，主要它的错误提示信息太高大上了，再加上我也没注意过这个依存关系，直接导致我在无数的错误堆里寻寻觅觅。

至此终于打开了我的SQL Server2008，心情太激动了！在解决这个问题的时候，有同学用dos命令解决过，给我的感觉就是太cool了，可是没解决得了，那些命令也不太清楚是什么意思，所以还是从简单的界面来吧。这些解决方案也许不适合你的问题，但是可以参考下，也欢迎交流更多关于SQL的问题。

PS：在找解决方法的过程中看到很多关于“配置SQL Server身份验证方式”的问题，如果你也遇到了类似的情况，可以看下我在网易的一篇博客
