Powershell SQL Server存储过程备份

Question

我正试图通过从Python程序传递参数来从SQL Server数据库备份一个特定的存储过程。这是我尝试过的代码，但一直出现错误。

param([string]$server='dbsed0898', [string]$dbname='global_hub',[string]$sp='dbo.gs_eligibility')
[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.SMO”) | out-null
$SMOserver = 'Microsoft.SqlServer.Management.Smo' #-argumentlist $server
$srv = New-Object("$SMOserver.Server") $server
$db = $srv.databases[$dbname]
$Objects = $db.storedprocedures[$sp]
$scripter = new-object ("$SMOserver.Scripter") $srv
$Scripter.Script($Objects) | Out-File 
" C:Usersfthoma15Documentsbackup_03212020.sql"
$db = $SMOserver.databases[$dbname]
$Objects = $db.storedprocedures[$sp]
$Scripter.Script($Objects) | Out-File 

"C:\Users\fthoma15\Documents\backup_03212020.sql">

错误：

为"Script"和参数计数找到多个不明确的重载："1">
在行：12个字符：5
+$Scripter.Script($Objects(|输出文件"C:\Users\fthoma15\Document…
+

有人能帮我吗？

以下是我所做的。

param([string]$server='test', [string]$dbname='test',[string[]]$sp=('test','test'))
[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SqlServer.SMO”) | out- 
null
$SMOserver = new-object ("Microsoft.SqlServer.Management.Smo.Scripter") #-argumentlist 
$server
$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("$server")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("$dbname")
$Objects = $db.storedprocedures[$sp[1,3]]
$scripter = new-object ("$SMOserver") $srv
$Scripter.Script($Objects) | Out-File 
"C:Usersfthoma15Documentsbackup_03212020.sql"

根据AlwaysLearning的建议，我将sp变量更改为数组列表，同时拆分schema和sp名称。
