推荐答案

这取决于您为应用程序使用的数据库类型。这里有两种数据库我想注意：



1.基于文件的数据库，这很容易更新，只需复制并粘贴到正确的位置，这些示例包括Access数据库文件（* .mdb），SQLite（* .sdb或任何，扩展名不受限制），SQL Server CE（* .sdf），...



2.基于服务的数据库，这有点棘手，您必须删除旧数据库，将新数据库附加到服务器，或使用还原功能（如果更新的数据库文件是备份） ，或者如果您的应用程序支持连接到多个数据库，只需创建一个新连接以附加更新的数据库。这些示例包括MS SQL Server（* .mdf和带有* .ldf的日志文件），MySQL，Oracle，......





我想你的更新数据库与旧数据库具有相同的结构。 （这意味着更新仅包含新数据，不涉及新结构）。

That depends on what kind of database you used for your application. There are 2 kinds of database here I want to notice:

1. File-based database, this is very easy to update, just copy and paste to the correct location, examples of these are Access database file (*.mdb), SQLite (*.sdb or any, the extension is not restricted), SQL Server CE (*.sdf),...

2. Service-based database, this is a little trickier, you have to remove the old database, attach the new one to the server, or using restore function (if the updated database file is a backup), or if your application supports connecting to multi databases, just create a new connection to attach the updated database. Examples of these are MS SQL Server (*.mdf and the log file with *.ldf), MySQL, Oracle, ...


I suppose your updated database has the same structure to the old one. (it means the update inludes only new data, not involving new structure).
