SQL命令使用Invoke-SQLCMD执行两次

Question

我正在与一个绝对让我大开眼界的问题作斗争。

我正在编写还原数据库脚本，该脚本在部署期间从PowerShell执行。

这是我的powershell脚本：

Param($RestoreDatabase, $RestoreDatabaseBackupPath, $RestoreDatabaseServer, $RestoreDatabaseUser)

Import-Module "SQLPS"                                   

$sqlcmd="C:\Program Files\Microsoft SQL Server\110\Tools\Binn\sqlcmd.exe"
$variables = ("db=$RestoreDatabase","BackupPath=$RestoreDatabaseBackupPath","user=${RestoreDatabaseUser}")
$inputFile = Join-Path (Split-Path $MyInvocation.MyCommand.Path -Parent) restore.sql

Write-Output "Executing SQLCMD: inputFile=$inputFile, Variables=$variables, ServerInstance=$RestoreDatabaseServer"

Invoke-SQLCmd -InputFile $inputFile -Variable $variables -ServerInstance $RestoreDatabaseServer -AbortOnError -Verbose -QueryTimeout 65535

Restore.sql（这不是原始文件，但仍然可以复制）

 print 'The first message is not repeating';

 use master
 GO

 print 'Setting the single user mode'
 alter database $(db) set single_user with rollback immediate
 GO

一切看起来都很简单，但powershell脚本的输出是：

 WARNING: The names of some imported commands from the module 'SQLPS' include unapproved verbs that might make them less discoverable. To find the commands with unapproved verbs, run the Import-Module command again with the Verbose 
 parameter. For a list of approved verbs, type Get-Verb.

   Invoke-SQLCmd : ALTER DATABASE failed because a lock could not be placed on database 'MY_DATABASE_STAGING'. Try again later.
   ALTER DATABASE statement failed.

正如您所说，输出中有两条相似的行

VERBOSE: Setting the single user mode

我认为该命令以某种方式调用了两次，这就是无法放置锁定的原因

我如何执行脚本：

  powershell -file Script.ps1 -RestoreDatabase MY_DB_STAGING -RestoreDatabaseBackupPath \\Storage\Backups\BACKUP.bak -RestoreDatabaseServer SERVERNAME\SQLEXPRESS -RestoreDatabaseUser "SERVERNAME\Checkee"

P.S。一切都像ssms的魅力

重复线条之谜导致我的方向错误。这只是用户权限问题。脚本在不同的帐户下运行顺畅。
