Question

我使用以下部署后脚本1部署DACPAC：

ALTER DATABASE [$(DatabaseName)] 
MODIFY FILE (NAME = [$(DatabaseName)], 
             SIZE = 100MB, MAXSIZE = UNLIMITED, FILEGROWTH = 20%)

但是，当我尝试引用此部署后脚本2时，部署失败：

ALTER DATABASE [$(DatabaseName)] 
MODIFY FILE (NAME = [$(DatabaseName)], 
             SIZE = $(size), MAXSIZE = UNLIMITED, FILEGROWTH = 20%)

所以，我的问题是传递大小的正确语法是什么？

我使用此命令启动脚本（第一个脚本1工作，脚本2不工作）

$resourceGroup = "SQL1"
$vmName = "SQL1"
$storageName = "sql1artifactsstorage111"
$ConfigurationPath = "C:\DSC\Ext\deployDB.ps1"
$ConfigurationName = "deployDB"
$configurationArchive = "deployDB.ps1.zip"
#Publish the configuration script into user storage
Publish-AzureRmVMDscConfiguration -ConfigurationPath $ConfigurationPath -ResourceGroupName $resourceGroup -StorageAccountName $storageName -force
#Set the VM to run the DSC configuration
$configurationArguments = 
@{
    Credential = Get-Credential;
    DatabaseName = 'Database1' 
    size = '100MB'
}
Set-AzureRmVmDscExtension -Version 2.22 -Name dscExtension -ResourceGroupName $resourceGroup -VMName $vmName -ArchiveStorageAccountName $storageName -ArchiveBlobName $configurationArchive -AutoUpdate:$true -ConfigurationName $ConfigurationName -ConfigurationArgument $configurationArguments

这是DSC显示的错误：

Dac Deploy Failed: 'Exception calling "Deploy" 
with "3" argument(s): "An error occurred during deployment plan generation. 
Deployment cannot continue."'

动态SQL是恶棍的最后避难所：

EXEC ('ALTER DATABASE [$(DatabaseName)] MODIFY FILE (NAME = [$(DatabaseName)],SIZE = $(size), MAXSIZE = UNLIMITED, FILEGROWTH = 20%)');
GO

为我工作，虽然是在本地部署，而不是通过Azure DSC。

这是一种通用的技术，用于做这些＆＃34; DBA-esque＆＃34;通常不支持TSQL变量替换的活动。

请注意未来的读者：这个技巧显然有效，也就是说OP已将其标记为答案。但是，由于工作站和构建服务器之间的DacFX版本不同，仅可能只需要，例如参见another SO post relating to the same error message。
