我正在制作一个在线应用程序,当我同步我的数据网络时,会执行不同表中的 25 到 30 个本地数据库查询。因此,大约需要 25 到 30 秒,因为所有数据库查询都以这种方式执行,首先检查本地数据库中是否存在数据(如果存在),然后更新行,否则插入。现在我想问一下,有什么方法可以同时执行这些所有查询。如果我能做到这一点,那么我可以在每次同步时节省 10 到 15 秒。所以请给出一个更好的解决方案来执行多个查询。

最佳答案

考虑使用高性能数据库管理系统,例如 cubeSQL :

SQLabs has announced the release of cubeSQL a fully featured and high performance relational database management system built on top of the sqlite database engine. It is the ideal database server for both developers who want to convert a single user database solution to a multiuser project and for companies looking for an affordable, easy to use and easy to maintain database management system. cubeSQL runs on Windows, Mac, Linux and it can be embedded into any iOS and Cocoa application.

cubeSQL is incredibly fast, has a small footprint, is highly reliable and it offers some unique features. It can be easily accessed with any JSON client, with PHP, with the native C SDK, with a Windows DLL and with an highly optimized REAL Studio plugin.
