PowerShell - 将文件名添加到要导入 SQL Server 的列列表中

Question

我正在尝试导入包含几列的电子表格 - 但我还想获取 Excel 文件的名称，以添加到要导入 MS SQL Server 的列列表中。

现在 - 下面的代码从电子表格中选择我想要的列并将它们导入到表格中。但我想做的是获取文件名并将其包含在导入到名为BatchFileName 的列中。

最终我想修改它以遍历文件夹并加载它找到的任何电子表格，但首先我想看看这是否可行。我尝试将变量添加到 Select-Object 中，但没有奏效。而且我目前没有任何其他想法。

这可能吗？如果是这样，如何做到这一点？

$FileDirectory = "C:\QualityReport\"
$FileName = "QualityReport05142021.xlsx"    
$BatchFileName = -JOIN ($FileDirectory,$FileName)    
Write-Host $BatchFileName    
$SQLInstance = "localhost"
$Database = "GenericDB"    
$data = Import-Excel -Path $ImportFile -WorksheetName "Sorted" | Select-Object "IP","Network","DNS","NetBIOS","Tracking Method","OS","IP Status","QID","Title","Vuln Status","Type","Severity","Port","Protocol","FQDN","SSL"    
#Write-Host $data   
Write-DbaDataTable -SqlInstance $SQLInstance -Database $Database -Table "dbo.QualityReport" -InputObject $data -Truncate

PowerShell 在许多 cmdlet 上支持 Calculated Properties。

您可以更改以下行（为清楚起见，换行）：

$data = Import-Excel -Path $ImportFile -WorksheetName "Sorted" `
  | Select-Object "IP","Network","DNS","NetBIOS","Tracking Method","OS","IP Status","QID","Title","Vuln Status","Type","Severity","Port","Protocol","FQDN","SSL"    

这样的：

$data = Import-Excel -Path $ImportFile -WorksheetName "Sorted" `
  | Select-Object @{Name="BatchFileName";Expression={$ImportFile}},"IP","Network","DNS","NetBIOS","Tracking Method","OS","IP Status","QID","Title","Vuln Status","Type","Severity","Port","Protocol","FQDN","SSL"
