powershell脚本在ISE中工作正常，但在powershell命令提示符下失败？

嗯，这个错误说得够多了。它无法识别“Get SqlInstances”函数

也许是ISE主机配置文件中的某些内容为该功能导入了适当的模块

你必须先检查一下。在ISE主机中运行时，执行以下命令：

Get-SqlInstances : The term 'Get-SqlInstances' is not recognized as the name of a cmdlet, function, script file, or
operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try
again.

我也有类似的问题。我的Powershell脚本执行快速检查以测试与SQL Server数据库的连接。它使用invokesqlcmd。它定期在命令提示符下工作。事实上，它刚刚在命令提示符下工作了3次，然后就停止了。没有任何更改，代码参考如下。但它在ISE中仍然有效我不明白它为什么停止了。欢迎提出任何建议。-

Powershell脚本的代码非常简单。 #================================================================================== #==脚本代码为：

Get-Content $($profile.CurrentUserCurrentHost)

#================================================================================== #==当我使用Powershell ISE时，脚本工作：

param(
 [Parameter(Mandatory=$true)][string]$csvFileName
,[Parameter(Mandatory=$true)][string]$SQLServer
,[Parameter(Mandatory=$true)][string]$SQLDBName
,[Parameter(Mandatory=$true)][string]$Username
,[Parameter(Mandatory=$true)][String]$Password
)
$ConnectTest = 'SELECT DBName = DB_NAME()'

Invoke-Sqlcmd -ServerInstance $SQLServer -Database $SQLDBName -Username $Username -Password $Password -Query $ConnectTest -Verbose

可能只发布两条以上的错误消息

 [Parameter(Mandatory=$true)][string]$csvFileName
,[Parameter(Mandatory=$true)][string]$SQLServer
,[Parameter(Mandatory=$true)][string]$SQLDBName

)
$ConnectTest = 'SELECT DBName = DB_NAME()'

Invoke-Sqlcmd -ServerInstance $SQLServer -Database $SQLDBName -Username $Username -Password $Password -Query $ConnectTest -Verbose
