在网上传闻SQLDMO是个好东西，当时没有注意这个传闻是什么时候了，后来才在微软的官网上看见，从SQL Server2008开始就不用SQLDMO了，取而代之的是SMO。无奈了，还写了个Helper。感觉DMO用起来比用SQLCMD少输些命令，而且如果用ADO.NET调用存储过程的话，好像还比DMO方便。
这个SQLDMO绝不是像别的dll那样直接添加引用的，它是个COM组件，要注册了才能使用，这说明了，凡是要跑带这个组件的程序，都要先注册一下组件。
在网上下一个SQLDOM的压缩包，解压后
第一步：首先将msvcr71.dll, SQLDMO.DLL, Resources\2052\sqldmo.rll,Resources\1033\sqldmo.rll 拷贝到C:\Program Files\Microsoft SQL Server\80\Tools\Binn目录。
下载SQLDMO文件
第二步：打开开始，在运行中输入 regsvr32 "C:\Program Files\Microsoft SQL Server\80\Tools\Binn\sqldmo.dll" 注册sqldmo.dll。
好了，是时候粘贴代码了
