Question

假设我有两个数据库服务器。

我有以下脚本

Function Query1($Query1) {
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection 
$SqlConnection.ConnectionString = "Server=db1.com;Initial 
Catalog=Report Server;Integrated Security=SSPI" 
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand 
$SqlCmd.Connection = $SqlConnection 
$SqlCmd.CommandText = $Query1 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
$SqlAdapter.SelectCommand = $SqlCmd 
$DataSet = New-Object System.Data.DataSet 
$a=$SqlAdapter.Fill($DataSet)
$SqlConnection.Close() 
$DataSet.Tables[0]} 

Function Query2($Query2) {
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection 
$SqlConnection.ConnectionString = "Server=db2.com;Initial 
Catalog=Report Server;Integrated Security=SSPI" 
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand 
$SqlCmd.Connection = $SqlConnection 
$SqlCmd.CommandText = $Query2 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
$SqlAdapter.SelectCommand = $SqlCmd 
$DataSet = New-Object System.Data.DataSet 
$a=$SqlAdapter.Fill($DataSet)
$SqlConnection.Close() 
$DataSet.Tables[0]}

$Result1 = Query1 "SELECT  [InstanceName]
      ,[ItemPath]
      ,ca.name as ObjectName
      ,(case
         when ca.type = 1 then 'Folder'
         when ca.type = 2 then 'Report'
         when ca.type = 3 then 'Resources'
         when ca.type = 4 then 'Linked Report'
         when ca.type = 5 then 'Data Source'
         when ca.type = 6 then 'Report Model'
         when ca.type = 7 then ' Report Part (SQL 2008 R2, unverified)'
         when ca.type = 8 then 'Shared Dataset (SQL 2008 R2)'
         when ca.type = 13 then 'PowerBI Report'
        End ) as ObjectType

$Result2 | Export-Csv -Path $file_Path\file.csv -NoTypeInformation

第二个查询将覆盖csv文件中第一个查询结果的结果。我需要两个查询都将其追加到同一文件，但是，我真的不想使用append，因为每次我运行脚本时，我都希望文件被新数据覆盖，因为每天都会运行

Answer 1

您使用的是Powershell v3还是更高版本？如果是这样，您应该能够按原样进行第一个查询，对于第二个查询，请使用“ -Append”添加到文件中。

但是，这将使您在文件中间出现第二个标题行。为避免这种情况，您可能需要添加

| Select-Object -Skip 1 |

Answer 2

现在我考虑一下...我可以在第二个查询上使用-Append ...因为第一个查询将始终重新创建文件，并且仅第二个查询需要追加到现有查询中！

$Result1 | Export-Csv -Path $file_Path\file.csv -NoTypeInformation
$Result2 | Export-Csv -Path $file_Path\file.csv -NoTypeInformation -append

如何合并2个查询结果并导出到一个csv文件？
