完整问题：使用 Invoke SQL 命令使用 Powershell 脚本，使用 snappins，我需要将它们包含在 SQL 作业中，Powershell 的 SQL Server 版本有些残缺，有人知道解决方法吗？

根据我收集到的信息，SQL Management Studio 的 powershell 版本功能不足，不允许使用 snappin，因此它无法识别我在脚本中使用的 cmdlet。我尝试在作业中将其作为命令行提示符而不是 Powershell 脚本运行，这会导致代码在一定程度上起作用，但是我检查了作业的历史记录，它说 invoke-sql 仍然不是可识别的 cmdlet。我推测，因为我在远程服务器上运行代码，使用的凭据与我的标准不同，我的预加载 snappin 的配置文件没有被加载，尽管这有点令人怀疑。

此外，由于我是一个 powershell 菜鸟，任何关于更好的编码实践/简化我的代码的建议都将不胜感激！

代码如下：

# define parameters
param
(
$file = "\\server\folder\file.ps1"
)

"invoke-sqlcmd -query """ | out-file "\\server\folder\file.ps1"

# retrieve set of table objects
$path = invoke-sqlcmd -query "select TableName from table WITH (NoLock)" -database db -server server

[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
$so = New-Object Microsoft.SqlServer.Management.Smo.ScriptingOptions

 $so.DriPrimaryKey = $false
 $so.Nocollation = $true
 $so.IncludeIfNotExists = $true
 $so.NoIdentities = $true
 $so.AnsiPadding = $false

# script each table
foreach ($table in $path)
{
#$holder = $table
$table =  get-item sqlserver:\sql\server\default\databases\database\tables\dbo.$($table.TableName)
$table.script($so) | out-file -append $file 
}


(get-content "\\server\folder\file.ps1") -notmatch "ANSI_NULLS"  | out-file "\\server\folder\file.ps1" 
(get-content "\\server\folder\file.ps1") -notmatch " AS "| out-file "\\server\folder\file.ps1" 
(get-content "\\server\folder\file.ps1") -notmatch "Quoted_" | out-file "\\server\folder\file.ps1"
(get-content "\\server\folder\file.ps1") -replace "\) ON \[PRIMARY\].*", ")" | out-file "\\server\folder\file.ps1"
(get-content "\\server\folder\file.ps1") -replace "\[text\]", "[nvarchar](max)" | out-file "\\server\folder\file.ps1"
(get-content "\\server\folder\file.ps1") -replace " SPARSE ", "" | out-file "\\server\folder\file.ps1"
(get-content "\\server\folder\file.ps1") -replace "COLUMN_SET FOR ALL_SPARSE_COLUMNS", "" | out-file "\\server\folder\file.ps1"


""" -database database -server server" | out-file "\\server\folder\file.ps1" -append

所以我想出了我自己问题的答案。使用本网站：http ://www.mssqltips.com/tip.asp?tip=1684和 http://www.mssqltips.com/tip.asp?tip=1199

I figured out that he was able to do so using a SQL Server Agent Proxy, so I followed the yellow brick road, and basically I set up a proxy to my account and was able to use the external powershell through a feature. A note, you need to create a credential under the securities tab in object explorer prior to being able to select one when creating the proxy. Basically I ended up creating a proxy named powershell, using the powershell subsystem, and use my login info to create a credential. VOILA!

您必须每次都添加管理单元。在您的编辑器中，您可能已经从另一个脚本/选项卡/会话中加载了它们。在 SQL Server 中，您需要在脚本的开头添加如下内容：

IF ( (Get-PSSnapin -Name sqlserverprovidersnapin100 -ErrorAction SilentlyContinue) -eq $null )
    {
        Add-PsSnapin sqlserverprovidersnapin100
    }
IF ( (Get-PSSnapin -Name sqlservercmdletsnapin100 -ErrorAction SilentlyContinue) -eq $null )
    {
        Add-PsSnapin sqlservercmdletsnapin100
    }

我不确定您要解决的错误-您可以发布吗？

您是否从 PowerShell 提示符尝试过这个？

添加-PSSnapin SqlServerCmdletSnapin100
