Question

我有一个充满来自cmdlet（来自BEMCLI模块）的数据的arraylist，并希望将数据存储在数据库中。声明每一列只是为了指定错误。

有一些关于类似错误代码的问题，但我不知道如何让解决方案适合我。

错误码：

No mapping exists from object type System.Data.Arraylist to a known managed
provider native type

Answer 1

感谢理查德提供正确的提示。收藏集会导致问题（AgentServer和AgentServerIdList）

我修复了上面的代码，在循环中添加$SqlCmd.Parameters.Clear()以清除每个循环中的参数。这就像'cannot declare @Variable twice'。

Commandline给了我另一个错误 - 所以我决定切换到.Parameters.AddWithValue - Command。

脚本现在运行正常。谢谢！

没有映射存在objecttype：Arraylist到本机类型
