将数据库文件包含在C ++项目中时出错

问题描述

我是C ++的新手，我试图使用SQLite3.h访问一个预填充的数据库。我将数据库文件（.db）添加到资源中，将其放置在与项目相同的文件夹中，并将sqqlite3.h添加到头文件夹。在主.cpp文件中，我只包括以下行。

I'm very new to C++ and I'm trying to use SQLite3.h to access a database that is pre-filled. I added the database file (.db) to resources, placed it in same folder as project and added "sqqlite3.h" to header file folder.In the main .cpp file, I included just the following line.

#include "MyDatabase.db"

我得到几个错误，如下所示。

I'm getting several errors such as below.

在这些错误之前，有数据库文件的位置。它似乎它试图读取.db文件和显示错误。

Before these errors there is the location for database file. It seems its trying to read the .db file and showing errors.

有一种方法可以将数据库作为资源，而不是C ++试图读取它。 （所有的.db文件中的信息都在表中。所以我很好奇C ++能够读取任何东西）。

Is there a way to include the database as a resource without C++ trying to read it. (All the information in .db file is in tables. So I'm curious about how C++ is able to read anything at all).

推荐答案

MyDatabase.db 不是库。您必须使用 include 将 .h 头文件导入到您的 .cpp 程序。

MyDatabase.db is not a library. You must use include to import .h header files to your .cpp program only.

，，和，您可以在C / C ++中找到一些使用 sqlite 数据库的方法。

Here , here , here and here you can find some methods to work with sqlite databases in C/C++.
