Question

尝试从文件中读取IP地址，将其插入SQL语句，然后执行并输出语句。

但是，只有第一个IP地址被插入SQL语句并被执行。

这是代码

$conn.Open()

foreach ($k in $file_line){

    $SQL = "SELECT dbo.sem_computer.COMPUTER_NAME,
    [IP_ADDR1_TEXT],dbo.sem_computer.COMPUTER_DOMAIN_NAME, dbo.SEM_COMPUTER.OPERATION_SYSTEM,NAME,dbo.SEM_AGENT.AGENT_VERSION, 
    Convert(VARCHAR(12),DBO.PATTERN.PATTERNDATE,107) as Antivirus_Date
    FROM dbo.sem_computer, [dbo].[V_SEM_COMPUTER], dbo.IDENTITY_MAP, dbo.SEM_CLIENT,dbo.SEM_AGENT,dbo.PATTERN
    WHERE [dbo].[V_SEM_COMPUTER].COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID
    AND dbo.SEM_CLIENT.GROUP_ID = IDENTITY_MAP.ID
    AND dbo.SEM_CLIENT.COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID
    AND SEM_COMPUTER.COMPUTER_ID = dbo.SEM_AGENT.COMPUTER_ID
    AND dbo.PATTERN.PATTERN_IDX = dbo.SEM_AGENT.PATTERN_IDX
    AND [IP_ADDR1_TEXT] = '$k'"

    write-host $SQL

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

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

            # Read Computer Name, Computer ID and IP address 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))
                write-host $sql_output

            }
            $transactionComplete = $true

        }
        catch{
            $transactionComplete = $false
        }
    }until ($transactionComplete)

}

$conn.Close()

这是输出

SELECT dbo.sem_computer.COMPUTER_NAME,
    [IP_ADDR1_TEXT],dbo.sem_computer.COMPUTER_DOMAIN_NAME, dbo.SEM_COMPUTER.OPERATION_SYSTEM,NAME,dbo.SEM_AGENT.AGENT_VERSION, 
    Convert(VARCHAR(12),DBO.PATTERN.PATTERNDATE,107) as Antivirus_Date
    FROM dbo.sem_computer, [dbo].[V_SEM_COMPUTER], dbo.IDENTITY_MAP, dbo.SEM_CLIENT,dbo.SEM_AGENT,dbo.PATTERN
    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 = SEM_COMPUTER.COMPUTER_ID
    AND SEM_COMPUTER.COMPUTER_ID = dbo.SEM_AGENT.COMPUTER_ID
    AND dbo.PATTERN.PATTERN_IDX = dbo.SEM_AGENT.PATTERN_IDX
    AND [IP_ADDR1_TEXT] = '10.10.10.1'

    AND dbo.SEM_CLIENT.GROUP_ID = IDENTITY_MAP.ID
    AND dbo.SEM_CLIENT.COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID
    AND SEM_COMPUTER.COMPUTER_ID = dbo.SEM_AGENT.COMPUTER_ID
    AND dbo.PATTERN.PATTERN_IDX = dbo.SEM_AGENT.PATTERN_IDX
    AND [IP_ADDR1_TEXT] = '10.10.10.2'

代码看起来正确，为什么它会停止执行并使PowerShell挂起？

Answer 1

导致挂起的可能原因是，执行生成异常的SQL语句出错会在异常处理程序中将$ transactionComplete设置为false。只要该异常继续发生，循环将继续执行。

假设$ cmd.ExecuteReader（）抛出异常，那么你就不会得到任何输出。

尝试添加一些代码来输出catch块中的内容，看看是否有任何有用的东西。

每行文本执行sql命令
