如何在任务计划程序上执行PowerShell脚本？

我正在尝试执行我的 Powershell 脚本，每 5 分钟运行一次。我尝试使用 Windows 7 的任务计划程序来运行它，但它在记事本上打开我的脚本，并且不会在我的数据库中插入任何内容

下面是我的 Powershell V-2.0 脚本。我不确定我的代码是否有问题（我对此表示怀疑），或者是否有办法将其包含在我的脚本中以每 5 分钟运行一次，比如说从上午 9 点到晚上 9 点。

我是这样安排的：

General
--------
Run only when user is logged on

Triggers
--------
Trigger: at 8h56am every day- 
Details: After triggered, repeat every 5 minutes indefinitely
Status: Enabled

Actions
-------
Action: Start a program
Details: Path to the script

提前致谢！

计划任务的操作必须调用powershell.exe将脚本文件作为参数传递。看http://blogs.technet.com/b/heyscriptingguy/archive/2012/08/11/weekend-scripter-use-the-windows-task-scheduler-to-run-a-windows-powershell-script.aspx http://blogs.technet.com/b/heyscriptingguy/archive/2012/08/11/weekend-scripter-use-the-windows-task-scheduler-to-run-a-windows-powershell-script.aspx

powershell.exe -file c:\path_to_your_script\script.ps1

执行脚本的用户需要拥有执行脚本中所有操作所需的权限。
