Question

我正在尝试将DACPAC部署到LocalDB 2012，但它只是没有它：

堆栈跟踪如下：

==================================

Could not deploy package. (Microsoft.SqlServer.Dac)

------------------------------
Program Location:

   at Microsoft.SqlServer.Dac.DeployOperation.Microsoft.SqlServer.Dac.IOperation.Run(OperationContext context)
   at Microsoft.SqlServer.Dac.OperationExtension.Execute(IOperation operation, Action`2 reportStatus, CancellationToken cancellationToken)

===================================

Unable to connect to target server. (Microsoft.Data.Tools.Schema.Sql)

------------------------------
Program Location:

   at Microsoft.SqlServer.Dac.OperationExtension.CompositeOperation.Microsoft.SqlServer.Dac.IOperation.Run(OperationContext context)
   at Microsoft.SqlServer.Dac.DeployOperation.Microsoft.SqlServer.Dac.IOperation.Run(OperationContext context)

现在因为我试图通过SSMS部署它，我知道我可以连接到服务器。我在Visual Studio中检查了解决方案，目标版本是针对SQL Server 2012的，连接字符串似乎是正确的。

有趣的是，通过Visual Studio进行部署工作，但是我无法将数据库升级到数据层应用程序，我收到此消息：

===================================

Database source is not a supported version of SQL Server (localdb)\MYINSTANCE: . (Microsoft.SqlServer.Dac)

   at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

我错过了什么？

Answer 1

更新到最新版本的SSMS应解决此问题。它可以在这里找到：https://msdn.microsoft.com/en-us/library/mt238290.aspx

否则，请确认您使用的LocalDB版本是LocalDB 2012.为此，您可以对服务器运行此查询：

$work_list[] = $row["work" . $i];

11.0.xxxx = SQL Server 2012
12.0.xxxx = SQL Server 2014
13.0.xxxx = SQL Server 2016

处理dacpac部署的库称为数据层应用程序框架或DacFX。 SSMS 2012使用的DacFX版本安装在：

$work_list = array();
$work_names = array();
for ($i=1; $i <= 11 ; $i++) {
    $work_names[] = "work$i";
}
$work_name_string = implode(', ', $work_names);
$query_work = mysql_query("SELECT DISTINCT $work_name_string FROM Test;"); 
while ($row = mysql_fetch_array($query_work)) {
    for ($i=1; $i <= 11 ; $i++) {
        $work_list[]= $row["work$i"];
    }
}

$work_list=array_merge(array_unique($work_list));

注意路径中的“110”，表示DacFX的版本最多支持SQL Server 2012. SSMS 2014在类似路径中查找DacFX，但在120文件夹中，该版本的DacFX最多支持SQL Server 2014，等等。

当要求DacFX部署到比支持的版本更新的服务器版本时，它将给出“无法连接”错误消息。（顺便提一下，在较新版本的DacFX中，错误信息得到了改进。）

在某个时间点，Visual Studio使用了上述路径中安装的DacFX版本，但是在SQL Server工具中发布SQL Server 2014支持的时候，进行了更改，Visual Studio获得了自己的副本

下的DacFX

select @@version

因此，您可以在不同版本的Visual Studio和SSMS之间获得不同的行为。

我遇到了同样的问题，通过更改＆＃34; C：\ program files（x86）\ Microsoft Sql Server \ 110 \ DAC \ bin＆＃34;中的可执行文件夹来解决此问题。到＆＃34; C：\ program files（x86）\ Microsoft Sql Server \ 120 \ DAC \ bin＆＃34;

谢谢， Chandana

DACPAC将无法部署，因为“无法连接到服务器”？
