推荐答案

如果您在应用程序中使用SQL Server，然后在运行该程序时，应用程序必须可以使用SQL Server实例。您无法在开发计算机上开发本地使用SQL服务器的应用程序，然后在无法访问SQL Server安装的计算机上运行它。



话虽如此，您不应该在客户端计算机上安装SQL Server。有几个原因：

0）您只能出于版权原因分发SQL Server Express - 而不是SQL Server完整版。

1）他们可能已经拥有SQL Server安装在网络上。如果是这样，那么他们可能会想要使用该版本。

2）如果他们确实安装了SQL服务器并且你开始扩散SQL服务器Express实例，那么你将会惹恼数据库管理员...

3）SQl Server的单站点安装比用户控制下的一些分散版本更有可能被备份。

4）对于普通用户来说，安装和管理Sql服务器非常复杂 - 这不是一个好主意！

5）它将破坏使用Sql Server而不是SqlCE或SQLite的主要优势 - 多用户访问。如果每个人都安装了自己的SQL服务器副本，那么您将拥有数据库的多个副本，每个副本由一个人使用。这会引起一些混乱，并且（取决于你如何编写原始数据库）在实现问题时可能需要付出相当大的努力才能组合成单个实例。



如果您为单个用户使用数据库，则使用独立数据库（而不是SQL Server） - 或者您要求麻烦！

If you use SQL server in you application, then an instance of SQL server must be available to the application when you run the program. You cannot develop an application which uses SQL server locally on your development machine and then run it on a computer which has no access to an SQL server installation.

Having said that, you should not install SQL server on a client machine. There are a couple of reasons:
0) You can only distribute SQL Server Express for copyright reasons - not SQL Server full version.
1) They may already have SQL Server installed on the network. If so, then they will presumably want to use that version.
2) If they do have SQL server installed and you start proliferating SQL server Express instances, you are going to annoy the heck out of the database administrator...
3) A single site installation of SQl Server is a lot more likely to be backed up than a number of scattered version under user control.
4) Sql server is quite complex for a "normal" user to install and administer - it is not a good idea!
5) It will destroy the primary advantage of using Sql Server over SqlCE or SQLite - multiuser access. If everyone installs their own copy of SQL server, then you will have multiple copies of your database, each used by a single person. This will cause some confusion, and (depending on how you wrote the original database) may take some considerable effort to combine into a single instance when the problem is realized.

If you are using a databse for a single user, then use a stand alone database (not SQL Server) - or you are asking for trouble!
