Question

我有一个SQL脚本来获取数据库大小，我需要在50个SQL服务器上运行它，每个服务器有大约10个数据库并获取每个数据库的报告。如何使用PowerShell执行该操作。

所以我的问题是如何从poweshell远程执行sql脚本并获取每个数据库的输出

这是我试图使用的脚本，我发现它在线并更新它但它无法正常工作

$dbservers=get-content "c:\powershell\list.txt"   
$Cre = Get-Credential -Credential xxxxxxxxxxxxx

ForEach-Object ($s in $dbservers)
 {
      [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO')       | out-null
$s = New-Object ('Microsoft.SqlServer.Management.Smo.Server') $server
$dbs = $s.Databases
$dbs | SELECT Name -ExpandProperty Name | ForEach-Object{
String]$database = $_
if (($database -ne "master") -and ($database -ne "tempdb") -and ($database -ne "msdb") -and ($database -ne "model"))  {
$ServerName = $dbservers
$DatabaseName = $database
$Query = "Create Table ##temp
     (
       ServerName nvarchar(250),
       DatabaseName sysname,
       Name sysname,
       physical_name nvarchar(500),
      size decimal (18,2),
      FreeSpace decimal (18,2)
          )   
        Exec sp_msforeachdb '
      Use [?];
      Insert Into ##temp (ServerName,DatabaseName, Name, physical_name, Size, FreeSpace)
      Select @@SERVERNAME ,DB_NAME() AS [DatabaseName], Name,  physical_name,
       Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) as nvarchar) Size,

      From sys.database_files '

    Select * 
    From ##temp
     where DatabaseName not in ('master','tempdb','model','msdb')
    drop table ##temp "

#Timeout parameters
 $QueryTimeout = 120
$ConnectionTimeout = 30

 #Action of connecting to the Database and executing the query and returning        results if there were any.
$conn = New-Object System.Data.SqlClient.SQLConnection
$ConnectionString = "Server={0};Database={1};Integrated    Security=True;Connect Timeout={2}" -f $ServerName, $DatabaseName,     $ConnectionTimeout
 $conn.ConnectionString = $ConnectionString
 $conn.Open()
 $cmd = New-Object system.Data.SqlClient.SqlCommand($Query, $conn)
 $cmd.CommandTimeout = $QueryTimeout
 $ds = New-Object system.Data.DataSet
 $da = New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
 [void]$da.fill($ds)
 $conn.Close()
  $ds.Tables 
  } 
  } 
  }

我收到此错误

 The following exception was thrown when trying to enumerate the collection:    "Failed to connect to server ..".
  At C:\Powershell\datafile.ps1:10 char:1
   +  <<<< $dbs | SELECT Name -ExpandProperty Name | ForEach-Object{

我通常不会对此类任务运行查询。 powershell可以访问数据库属性。我将为您提供在特定服务器上运行的代码，您可以做的是在服务器循环内部调用它就可以了。如果不起作用只是告诉我，我会发送更多的定制方式来做到这一点。你可以管道我的功能不包括系统数据库。我现在懒得去做。

Function Get-FSqlDBFileSizes([string]$serverInstance)
{
  [void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
    try {


    $results = @()

    $server = new-object Microsoft.SqlServer.Management.Smo.Server $serverInstance

    foreach ($db in $server.Databases)
    {
        $dbname = $db.Name
        $fileGroups = $db.FileGroups
        $intRow=0
        foreach ($fg in $fileGroups) {
            If ($fg) {
                $intRow++

                $mdfInfo = $fg.Files | Select Name, FileName, size, UsedSpace
                $result = New-Object -TypeName PSObject -Property @{
                    DBName = $dbname
                    Name = $mdfInfo.Name
                    FileName = $mdfInfo.FileName
                    Size = ($mdfInfo.size / 1000)
                    UsedSpace = ($mdfInfo.UsedSpace / 1000)
                }
                $results += $result

                $logInfo = $db.LogFiles | Select Name, FileName, Size, UsedSpace
                $result = New-Object -TypeName PSObject -Property @{
                    DBName = $dbname
                    Name = $logInfo.Name
                    FileName = $logInfo.FileName
                    Size = ($logInfo.size / 1000)
                    UsedSpace = ($logInfo.UsedSpace / 1000)
                }
                $results += $result
            }
        }
    }

    Write-Output $results
}
catch [Exception] {
    Write-Error $Error[0]
    $err = $_.Exception
    while ( $err.InnerException ) {
        $err = $err.InnerException
        Write-Output $err.Message
    }
}
}
