Question

根据我的理解，我的查询结果未正确保存/转发。应该发生的是每个服务器（svr01，svr03，svr05，svr06，svr08）我应该获得他们的操作系统，完整域名等。然后这个信息用于填充我的SQL数据库（Hal0Test）。但是，该信息永远不会被发送，我不知道如何解决这个问题。

我在我的powershell脚本中添加了一个小的html输出，以便在本地查看我的结果。 html对我来说更容易打开然后运行SQL Server Management Studio并刷新该程序。但我仍然希望将所有这些变量发送到数据库。

目标：纠正重复的问题和开始将该信息发送到我的sql数据库。如果你能帮助我那将是令人惊叹的！

代码：

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

$table = new-object “System.Data.DataTable”
$table.Load($ServerNames)

$ServerArray = $table | select -Expand ServerName

您正在最外层的foreach循环中创建基于HTML的报告，但您的$_仅限于当前正在处理的服务器。相反，在主循环开始之前将包装器HTML放入$Outputreport，然后在循环内添加包含当前数据的<tr>...</tr>部分。并将第二个循环放在$ServerArray上。还在报告中添加了$result，显然所有更新查询都会生成0 row(s) updated而您不明白为什么。（一个疯狂的猜测：编码不匹配（UTF16与数据库的UTF8））可能你可能决定INSERT INTO ServerList数据并删除旧行，这样你的关键字段肯定会是一致的。

#Start of HTML Code
$Outputreport = "<HTML><TITLE> IDI Server Report </TITLE>
                <BODY background-color:peachpuff>

$ServerArray | ForEach-Object {
    # $ServerArray returns each server name
    # collection code skipped
    $command.CommandText = "UPDATE ServerList SET FQDN = '$_', OS = '$($os.Caption)' WHERE ServerName LIKE '$($os.PSComputerName)%';"
    $result = $command.ExecuteNonQuery()
    if($cpuAVG.Average -ge "2")  
      {  
        $Outputreport += "<TR bgcolor=#FF0000>"  
      }  
    else 
      { 
        $Outputreport += "<TR bgcolor=#E6E6FA>"  
      } 
    $Outputreport += @"
        <TD>$($os.PSComputerName)</TD>
        <TD align=center>$($_)</TD>
        <TD align=center>$($cpuAVG.Average)%</TD>

        <TD align=center>$($result)</TD></TR>
        "@
    # used a here-string for clarification  
} 
$Outputreport += "</Table></BODY></HTML>"

我还将where子句更改为like语句，可能您的数据库在ServerName列中包含FQDN。
