问题描述

我的电脑被重新格式化了。我有一个VS项目的备份副本。现在已经下载了新的Visual Studio 2019和SQL Server 2017 Express。尝试附加我的数据库并在打开解决方案/项目时收到此错误消息:

My PC was reformatted . I had a back up copy of my VS project. Now have downloaded the new Visual Studio 2019 and SQL Server 2017 Express. Trying to attach my databases and get this error message when opening solution/project:

"Web项目'NAMED'需要SQL Server 2012 Express LocalDB,此版本未安装在此

计算机。



要升级项目数据库以使用最新的SQL Server Express LocalDB,请按
双击数据库文件按照说明。注意:在此升级之后,使用早期版本的Visual Studio无法修改项目数据库。$


继续使用相同的版本此项目的数据库,从<
Microsoft下载中心安装"

"The Web project 'NAMED' requires SQL Server 2012 Express LocalDB which is not installed on this
computer.

To upgrade the project database to use latest SQL Server Express LocalDB,
double click the databse file and follow the intructions. Note: After this upgrade,
the project databse can't be modified using earlier version of Visual Studio.

To continue using the same database for this project, install it from the
Microsoft Download Center"

我不再是 我的计算机上有旧版本的SQL Server。我是否需要重新安装旧版本才能使用新版本?我的意思是,我下载了2017版本。那么我还可以安装2012版吗?然后是否有办法更新
旧版本以使用新版本,以便我可以卸载旧版本?

I no longer  have the older versions of SQL server on my computer. Do I need to reinstall the old version to use the new version? What I mean is, I down loaded the 2017 version. So can I also install the 2012 version? And then is there a way to update the old version to use new version so that I can then uninstall old version?

感谢您的帮助。

如果要从SQL 2012升级到2017,则版本必须是SQL Server 2012 SP2或更高版本。请参阅

Hi RaekC,

>> Do I need to reinstall the old version to use the new version?

Yes, you need.

>> What I mean is, I down loaded the 2017 version. So can I also install the 2012 version? 

Yes, you can. You can download different version of SQL server on same server.

>>And then is there a way to update the old version to use new version so that I can then uninstall old version?

If you want upgrade from SQL 2012 to 2017, the version must be SQL Server 2012 SP2 or later. Please refer to Supported Version and Edition Upgrades for SQL Server 2017.

Best regards,
Cathy Ji
