Add-PSSnapin SqlServerCmdletSnapin *和SqlServerProviderSnapin *的最佳位置在哪里？

Question

我创建了一些psm1文件，并将以下行放在每个psm1文件的顶部，

Set-StrictMode -Version 2
Add-PSSnapin SqlServerCmdletSnapin*
Add-PSSnapin SqlServerProviderSnapin*

然而，它得到了警告

WARNING: The names of some imported commands from the module 'mymodule' include unapproved verbs that might make them
 less discoverable. To find the commands with unapproved verbs, run the Import-Module command again with the Verbose
parameter. For a list of approved verbs, type Get-Verb.

如果多次导入模块，会出现以下错误。

Add-PSSnapin : An item with the same key has already been added.
At line:1 char:1
+ Add-PSSnapin SqlServerCmdletSnapin*
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Add-PSSnapin], ArgumentException
    + FullyQualifiedErrorId : System.ArgumentException,Microsoft.PowerShell.Commands.AddPSSnapinCommand

或者有没有办法在系统启动时为每个用户加载这些管理单元？

警告只是说SqlServerCmdletSnapin和SqlServerProviderSnapin的作者使用了一些“未经批准”的名称来表示其功能。但是这些功能可以正常工作，不过MS认为它们可以“不易被发现”（当用户搜索命令如写“Get-”并从PS控制台按Tab-Tab-Tab ...时）。

所以你把它们放在首位是正确的，只需添加-ErrorAction SilentlyContinue即可消除警告：

Add-PSSnapin SqlServerCmdletSnapin* -ErrorAction SilentlyContinue 
Add-PSSnapin SqlServerProviderSnapin* -ErrorAction SilentlyContinue

至于为每个用户加载这些管理单元，有几个选项可以使用配置文件来完成。阅读Understanding the Six PowerShell Profiles文章。
