Question

我正在尝试创建一个脚本来查看.txt文档中的服务器列表，并查找该服务器上的SQL实例以及每个实例的sql service pack版本构建。脚本运行但不返回任何信息。我认为我遇到了$ svcPack变量和找到所需数据的相应变量。任何帮助都会受到极大的关注。感谢。

嗯，从它的外观来看，这是一个小错误。在评估$ VersionBuild时，您没有任何 else 语句。所以，如果它没有通过第一次评估：

if($versionBuild -eq $vs2008r2sp2)

然后它将不会继续，并评估它是否可能是其他版本。

我要做的另一件事是在if语句中使用-eq，而不是使用-match并缩短版本字符串。这样，如果版本字符串与版本字符串不完全匹配，则更有可能匹配。例如您试图检查版本$vs2005sp4 = "9.00.5000";，但VersionString属性将返回"9.00.5000.00"，如果您使用-eq不起作用，但如果您使用-match它将工作

因此，添加else语句，缩短版本字符串，并使用-match代码块将如下所示：

# Sets the server versions
$vs2005sp4 = "9.00.5000";
$vs2008sp3 = "10.00.5500";
$vs2008r2sp2 = "10.50.4000";

#...

    # Set background color to green if service pack is 2008r2 SP2
    if($versionBuild -match $vs2008r2sp2)
    {
        $color = $greenColor           
}
else
{
        # Set background color to yellow if service pack is 2008 SP3
        if($versionBuild -match $vs2008sp3)
        {
            $color = $yellowColor
    }
    else
    {
            # Set background color to orange if service pack is 2005 SP4
            if($versionBuild -match $vs2005sp4)
            {
                $color = $orangeColor   

                # Create table data rows 
                #<td width='15%' align='center'>$instanceID</td>
                $dataRow = "
                    <tr>
                        <td width='10%'>$computer</td>                        
                        <td width='5%' align='center'>$versionBuild</td>
                        <td width='10%' align='center'>$versionName</td>
                    </tr>
                "
    }
    else
    {
                # If statement needed to remove label that were null
                If ($versionID -ne 'null') 
                {
                    Add-Content $servicePackReport $dataRow;
                    Write-Host -ForegroundColor DarkYellow "$computer $deviceID service pack build = $versionBuild";
                    $i++        
                }
            }
        }

要回答@ user1700796的问题，我认为@ user1700796遇到的真正问题是该脚本不适用于具有多个实例的SQL服务器。即当你得到Smo.Server对象时：

$svcPacks = New-Object -typeName Microsoft.SqlServer.Management.Smo.Server($computer)

其中$computer是服务器名称，并且在该服务器上有多个实例;返回单个 Smo.Server对象，该对象基本上是空的。即拉出VersionString会返回一个空字符串。

如果相反，您运行相同的命令，除了为每个实例输入完整的SQL服务器名称+实例名称，然后Smo.Server对象返回正确的信息。

这是因为Smo.Server对象使用SQL连接字符串连接到SQL服务器（请参阅ConnectionContext属性），并且它一次只能连接到单个实例，并且不会枚举通过您可能期望的实例。

因此，您需要：

，而不是在Smo.Server对象上使用foreach循环

首先使用几个命令获取计算机名称并枚举该框中SQL Server实例的名称
- 对于前。请参阅：PowerShell list all SQL instances on my system
拿那些SQL服务器实例，然后对这些名称做一个foreach循环
您使用这些SQL Server实例名称来获取Smo.Server对象
然后，您可以从Smo.Server对象中提取版本字符串。

查找SQL Server实例＆amp;使用PowerShell构建Service Pack
