Powershell 脚本到 SQL Server 数据库

Question

我有这个 PowerShell 脚本，它将收集我的远程服务器的系统信息。

我的问题：我不确定在运行时如何使用此脚本来填充我在 SQL Server Management Studio 中创建的新创建的数据库Hal0Test。

最终目标：我希望我的 powershell 脚本查看远程服务器中的列 QAUTILITYDB01 > ServerList（数据库）> 标记为“ServerName”取“QACGAPPSVR01, QACGAPPSVR03等"将这些值中的每一个推送到我的 powershell 脚本中，并为每台服务器生成其 FQDN 和操作系统。最后，将新值（FQDN 和 OS）推送回远程数据库。

新的 Powershell 脚本代码：

$connectionString = "Server=QAUTILITYDB01;Database=Hal0Test;Integrated Security=True;"
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$command = $connection.CreateCommand()

$ServerArray = [System.Collections.ArrayList]@()
$query = "SELECT ServerName FROM ServerList"
$command.CommandText = $query
$ServerNames = $command.ExecuteReader()

While ($ServerNames.read()){
    $ServerArray.Add($ServerNames[0])
}

foreach($Server in $ServerArray){
    # $Server returns each server name
    $os    = Get-WmiObject -Class Win32_OperatingSystem -Computer $_
    $disks = Get-WmiObject -Class Win32_LogicalDisk -Computer $_ |
             Where-Object {$_.DriveType -eq 3} |
             ForEach-Object {
                 '{0} {1:D} MB Free/{2:D} MB Used' -f $_.DeviceID,
                     [int]($_.FreeSpace/1MB), [int]($_.Size/1MB)
             }

    New-Object -Type PSCustomObject -Property @{
      'FQDN'            = $_
      'ServerName'      = $os.PSComputerName
      'OperatingSystem' = $os.Caption
      'Disks'           = $disks -join ' | '
    }
    $command.CommandText = "UPDATE ServerList SET FQDN = '$_', OS = '$os.Caption' WHERE ServerName = '$os.PSComputerName';"
    $result = $command.ExecuteNonQuery()

} Export-Csv 'C:\Desktop\HalO\output.csv' -Delimiter '|' -NoType

Powershell CSV 文件：

ServerName  FQDN    Disks   OperatingSystem
SVR01   Svr01.xxx.com   C: 17899 MB Free/51097 MB Used | E: 22277 MB Free/25597 MB Used Microsoft Windows Server 2008 R2 Enterprise 
SVR03   svr03.xxx.com   C: 18280 MB Free/61337 MB Used | E: 50079 MB Free/56317 MB Used Microsoft Windows Server 2008 R2 Enterprise 
SVR05   svr05.xxx.com   C: 8751 MB Free/40857 MB Used | E: 4987 MB Free/10237 MB Used   Microsoft Windows Server 2008 R2 Enterprise 
SVR06   svr06.xxx.com   C: 14188 MB Free/61337 MB Used | E: 34962 MB Free/56317 MB Used Microsoft Windows Server 2008 R2 Enterprise 
SVR08   Svr08.xxx.com   C: 6464 MB Free/40857 MB Used | E: 5921 MB Free/10237 MB Used   Microsoft Windows Server 2008 R2 Enterprise 

错误：

Exception calling "ExecuteNonQuery" with "0" argument(s): "There is already an open DataReader 
associated with this Command which must be closed first."

SQL Server 列表：

Answer 1

在脚本开头设置 SQL Server 连接：

$connectionString = "Server=ulidb01;Database=Hal0Test;Integrated Security=True;"
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$command = $connection.CreateCommand()

执行查询以更新服务器：

$command.CommandText = "UPDATE ServerList SET FQDN = '$_', OS = '$os.Caption' WHERE ServerName = '$os.PSComputerName';"
$result = $command.ExecuteNonQuery()

好的--现在回到顶部获取服务器名称列表：

$ServerArray = [System.Collections.ArrayList]@()
$query = "SELECT ServerName FROM ServerList"
$command.CommandText = $query
$ServerNames = $command.ExecuteReader()

While ($ServerNames.read()){
    $ServerArray.Add($ServerNames[0])
}

这将为您提供服务器名称的数组列表 ($ServerArray)。所以你在外循环中遍历这个数组列表：

foreach($Server in $ServerArray){
    # $Server returns each server name
}

...或者您可以将其保留为将其通过管道传输到 foreach-object 中。我只是不想在脚本中使用管道，因为它更容易阅读。

然后在脚本的最后你需要关闭 SQL Server 连接：

$connection.Close()
