空路径名不合法 - DTEXEC with Powershell

Question

我尝试从本地计算机在远程服务器上使用 Powershell 运行 DTSX，但文件路径变量未到达 DTSX 执行中，因此我收到错误“空路径名不合法。”

这是我运行的命令的示例：

$server = "server name"
$credential = Get-Credential

$command = @'
"G:\Program Files\Microsoft SQL Server\160\DTS\Binn\DTExec.exe" /F "G:\insert-data.dtsx" ^
/SET \Package.Variables[User::file_data].Value;"\\servername\data.csv" ^
/SET \Package.Variables[User::file_log].Value;"G:\insert_data_log.txt" ^
/SET \Package.Variables[User::db_destination_server].Value;"servername" ^
/SET \Package.Variables[User::db_destination_name].Value;"dbname" ^
/SET \Package.Variables[User::db_destination_user].Value;"username" ^
/SET \Package.Variables[User::db_destination_password].Value;"pass" ^
/SET \Package.Variables[User::db_destination_table].Value;"tablename" ^
/SET \Package.Variables[User::days].Value;1
'@

Invoke-Command -ComputerName $server -Credential $credential -ScriptBlock {
    param($cmd)
    try {
        Start-Process -FilePath "cmd.exe" -ArgumentList "/c `"$cmd`"" -NoNewWindow -Wait -RedirectStandardOutput "C:\Temp\command_output.txt" -RedirectStandardError "C:\Temp\command_error.txt"
    } catch {
        $_ | Out-File -FilePath "C:\Temp\remote_command_error.txt"
    }
} -ArgumentList $command

file_log 变量由我的“Start LOG”任务使用，在执行进程时为空。这是我收到的错误：

我尝试将文件的路径放在双引号和单引号中，但没有任何效果。 任何建议都会受到欢迎！

Answer 1

问题是通过

cmd.exe

参数调用

/C

的 CLI 不支持传递 multiline 代码 - 第一行之后的所有内容都会被悄悄忽略。

如果您想保留多行源代码定义以提高可读性/可维护性，您可以在使用前以编程方式将其转换为单行。

也就是说，将以下语句放在

try

语句之前：

# Transform the multiline source code to a single-line form.
$cmd = $cmd -replace '\^\r?\n'

• 上面使用基于正则表达式的

  -replace

  运算符从多行源代码中删除所有行延续。
