查询列表从SQL数据库

取IP地址从IP地址的列表
将其插入到SQL查询地址
输出结果

到目前为止，该代码仅适用于包含一个IP地址的情况。如果我包含多个脚本无限期挂起

此代码似乎是正确的，应该修复哪些内容？

$file = Get-Content C:\list.txt 

$conn.Open() 

foreach ($k in $file){ 
    write-host $k 

    $sql = "SELECT dbo.sem_computer.COMPUTER_NAME,[IP_ADDR1_TEXT],(dbo.SEM_AGENT.FREE_DISK/1073741824)as 'Free Disk Space (GB)', 
    (dbo.SEM_COMPUTER.DISK_TOTAL/1073741824) as 'Total Disk Space (GB)', 
    (dbo.SEM_AGENT.FREE_MEM/1073741824) as 'Free Memory (GB)', (dbo.SEM_COMPUTER.MEMORY/1073741824) as 'Total Memory (GB)', 
    dbo.SEM_COMPUTER.OPERATION_SYSTEM,NAME, SEM_AGENT.MAJOR_VERSION 
    FROM dbo.sem_computer, [dbo].[V_SEM_COMPUTER], dbo.IDENTITY_MAP, dbo.SEM_CLIENT, dbo.SEM_AGENT 
    WHERE [dbo].[V_SEM_COMPUTER].COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID 
    AND dbo.SEM_CLIENT.GROUP_ID = IDENTITY_MAP.ID 
    AND dbo.SEM_CLIENT.COMPUTER_ID = dbo.SEM_COMPUTER.COMPUTER_ID 
    AND dbo.SEM_COMPUTER.COMPUTER_ID = dbo.SEM_AGENT.COMPUTER_ID 
    AND [IP_ADDR1_TEXT] = '$k'" 

    $cmd = New-Object System.Data.SqlClient.SqlCommand($sql,$conn) 

    do{ 
    try{ 
     $rdr = $cmd.ExecuteReader() 

     # Read Computer Name, Computer ID, IP address, Domain, and Operating System from the Database into a multidimensional array 

     while ($rdr.read()){ 
      $sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1), $rdr.GetValue(2), $rdr.GetValue(3), $rdr.GetValue(4), $rdr.GetValue(5), $rdr.GetValue(6), $rdr.GetValue(7), $rdr.GetValue(8)) 
     } 
     $transactionComplete = $true 
    } 
    catch{ 
     $transactionComplete = $false 
    } 
    }until ($transactionComplete) 
} 

Write-host $sql_output 

$conn.Close()

你有没有考虑为建设循环中的SQL连接？另外，如果写入$ sql_output时出错，您将永远运行。对于故障排除，我会写$ host来保证文本是正确的，然后花时间确保您正确使用读写器。 – websch01ar

谢谢@ websch01ar你的解决方案的作品！ – Glowie

我已将评论添加为答案。如果你不介意，是否只是SQL连接？ – websch01ar

显然，这是答案（从评论）：

通过将$ conn.Open（）移动到for循环中，我在for循环中构建了SQL连接 – Glowie

我可能只是测试，如果这个工程第一：

$file = Get-Content C:\list.txt 

$conn.Open() 

foreach ($k in $file){ 
    write-host $k 

    $sql = "SELECT dbo.sem_computer.COMPUTER_NAME,[IP_ADDR1_TEXT],(dbo.SEM_AGENT.FREE_DISK/1073741824)as 'Free Disk Space (GB)', 
    (dbo.SEM_COMPUTER.DISK_TOTAL/1073741824) as 'Total Disk Space (GB)', 
    (dbo.SEM_AGENT.FREE_MEM/1073741824) as 'Free Memory (GB)', (dbo.SEM_COMPUTER.MEMORY/1073741824) as 'Total Memory (GB)', 
    dbo.SEM_COMPUTER.OPERATION_SYSTEM,NAME, SEM_AGENT.MAJOR_VERSION 
    FROM dbo.sem_computer, [dbo].[V_SEM_COMPUTER], dbo.IDENTITY_MAP, dbo.SEM_CLIENT, dbo.SEM_AGENT 
    WHERE [dbo].[V_SEM_COMPUTER].COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID 
    AND dbo.SEM_CLIENT.GROUP_ID = IDENTITY_MAP.ID 
    AND dbo.SEM_CLIENT.COMPUTER_ID = dbo.SEM_COMPUTER.COMPUTER_ID 
    AND dbo.SEM_COMPUTER.COMPUTER_ID = dbo.SEM_AGENT.COMPUTER_ID 
    AND [IP_ADDR1_TEXT] = '$k'" 

    $command = $conn.CreateCommand() 
    $command.CommandText = $sql 
    $sql_output = $command.ExecuteReader() 
} 

Write-host $sql_output 

$conn.Close()

然后加入错误处理（try/catch语句）之后。
