Question

我的Transact SQL脚本有问题，我在Transact SQL中创建了一个过程，该过程必须使用函数执行powershell脚本。当我在命令提示符中执行文件和方法时，它可以工作，但是如果我将命令放在Transact SQL中，它会给我一个错误，说它不能识别命令。我希望有人可以帮助我。

命令提示符命令

powershell -command "& { . C:\Users\mslaats\Desktop\Databasescripts\Powershell\GmailLibrary.ps1; SendGmail "<email address>" "subject" "body" }"

Transact SQL脚本

PRINT 'Use the Divestar database'
USE [Divestar]
GO

PRINT 'Grant access to execute through a kind of cmd'
EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
GO
RECONFIGURE
GO

-- Delete the old procedure
PRINT 'Drop procedure'
DROP PROCEDURE IF EXISTS [dbo].[SendEmail]
GO

-- Procedure --
PRINT 'Create procedure to send an email'
GO
CREATE PROCEDURE [dbo].[SendEmail]
    @To         VARCHAR(1024),
    @Subject    VARCHAR(1024),
    @Content    VARCHAR(1024)
AS
BEGIN
    DECLARE @CMD    VARCHAR(1024)

    SET @CMD = 'powershell -command "& { . "C:\Users\mslaats\Desktop\Databasescripts\Powershell\GmailLibrary.ps1"; SendGmail "<email address>" "onderwerp" "bodytje" }"'
    PRINT @CMD

    EXEC xp_cmdshell @CMD
END
GO

遇到同样的问题后，我发现我需要检查两台机器上的ExecutionPolicy。我知道我的ExecutionPolicy在我的机器上很好，但是我通过以下方式检查了SQL服务器机器：

EXEC master..xp_cmdshell 'powershell -command "& { Get-ExecutionPolicy }" '

返回Restricted（这意味着没有Powershell脚本可以运行，因此我遇到了与您相同的错误消息）。

此外，我还确保我的脚本存储在SQL Server有权访问的位置。您可以使用如下命令检查此情况：

EXEC master..xp_cmdshell 'powershell -command "& { dir C:\Users\mslaats\Desktop\Databasescripts\Powershell }" '

该命令将告诉您SQL是否可以看到您的脚本。就我而言，我将脚本放在一个我知道SQL可以访问的共享网络位置。
