问题
对于DBA或者其他运维人员来说授权一个账户的相同权限给另一个账户是一个很普通的任务。但是随着服务器、数据库、应用、使用人员地增加就变得很枯燥乏味又耗时费力的工作。那么有什么容易的办法来实现这个任务吗？
当然，作为非DBA在测试甚至开发环境也会遇到这种问题，要求授予所有服务器数据库的某个权限给一个人的时候。我们是不是有什么其他办法提高效率？
解决方案
如果这个时候我们网上去搜索解决方案，大多数时候搜到的都是使用T-SQL解决方案，但是这又会产生下面几个小问题:
- 我们需要到目标服务器上执行这些脚本，有的甚至还需要部署后执行一遍。
- 不能生成这些T-SQL脚本到一个文件中。
- 重度使用的动态脚本代码冗长不方便阅读和维护。
本篇技巧的主要目的就是提供一个更好的基于PowerShell和SMO的解决方案来解决上述问题。
新的PS方法
- 在cmdlet函数中，可以接收一个SQLServer实例名称的列表以及登陆名（$OldLogin）,这些登陆名的权限是准备复制的。
- 对于每个实例，使用SMO Server.EnumObjectPermissions(loginName) 来获取服务对象（如登陆账号）权限并且使用Server.EnumServerPermissions(loginName) 来获取服务器级别的权限。
- 使用来查找每个存在数据库登陆账户映射$OldLogin账户关系的数据库
- 在每个映射用户的数据库中，我们可以通过 , , 和 EnumObjectPermissions 来获得用户的证书、对称以及非对称秘钥、ServiceBrokers等等来检索用户的所有权限。
- 所有检索到的权限信息将被添加到一个哈希表的数组汇总，然后通过循环数组导出权限脚本到一个文件中或者运行这个脚本用来复制一个新的账户权限。
测试环境
现在我把从网上找到的脚本进行修改完善，然后如下的脚本列出来如下：

在这个环境中，把所有不同的grant/deny 权限，来自用户[Bobby]的权限，不论是服务器登陆账户还是数据库账户的权限都获取了。总之，这就是一个权限 的grant/deny 脚本。

在我本地的电脑上，我有两个数据库实例，一个叫做[TP_W520](默认)，另一个叫做[TP_W520\SQL2014]。分别在两个实例上运行。ok，接下来就是PowerShell 脚本了。

开始测试
打开一个PowerShell ISE的窗口，复制、黏贴这个PS脚本到一个新的窗口，然后还需要取消最后一行的注释(还有修改服务器参数的名称：-Server parameter)，接着运行脚本。
你将会看到一个新生成位于c:\temp\Bobby_perm.sql 的脚本。然后在NotePad 中打开这个脚本，如下：

注意： 看到生成的脚本与我们之前总结的有一点不同，因为授权的同时默认授权的了连接权限。否则，如果连接不被许可那么第一步创建账户都不能实现。
现在我们看一下复制[Bobby]权限到新账户[Johnny]。其中为[Johnny]生成权限审计脚本。使用如下两行：
# clone [Bobby] to [Johnny]Clone-SQLLogin -Server $Env:ComputerName, "$ENV:COMPUTERNAME\sql2014" -OldLogin Bobby -NewLogin Johnny -NewPassword "P@s$w0Rd" -Execute;# generate a permission auditing script, change parameter valeus to your needs, make sure [OldLogin] and [NewLogin] are same.Clone-SQLLogin -Server $Env:ComputerName, "$ENV:COMPUTERNAME\sql2014" -OldLogin Johnny -NewLogin Johnny -FilePath "c:\temp\Johnny_perm.sql";
我们可以比较之前的c:\temp\Bobby_perm.sql与新的c:\temp\Johnny_perm.sql 然后发现他们是完全一样的除了账户名称。
总结
查找并复制用户的权限在SQLServer内是一个普遍的任务。利用这个技巧我们可以创建一个高级的PowerShell 函数来做这个工作来处理多服务器的情况，没必要去分别到目标服务器去执行代码。同时建议将这个PS脚本放到一个module中来正常使用，因此当你需要的时候只需要加在PS文件就可以自动加载该功能了。
这个脚本适合我当前的工作，但是如果想进一步升级这个功能比如属性列表和可利用群组等权限则还需要进一步完善，同时要求数据库是2012及其以后版本才能支持。由于目前我的服务器还存在大量2008r2 所有我只能暂时忽略这些了。不过目前看也是够用了。
