sql-server - Powershell SQL Server 存储过程备份

Question

我正在尝试通过从 Python 程序传递参数来从 SQL Server 数据库中备份一个特定的存储过程。这是我尝试过的代码，但我不断收到错误消息。

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:\Users\fthoma15\Documents\backup_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“脚本”和参数计数找到多个模棱两可的重载：“1”。
在 line:12 char:5
+ $Scripter.Script($Objects) | Out-File "C:\Users\fthoma15\Document ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest

有人能帮我吗？

Answer 1

这就是我所做的。

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

正如 AlwaysLearning 所建议的，我将 sp 变量更改为数组列表，拆分模式和 sp 名称。
