将内存中的sqlite数据库转换为blob / char数组 [英] Converting in-memory sqlite database to blob/char array
问题描述
我有一个内存中的sqlite数据库,我想转换成一个简单的blob,我想这样做,最好不使用任何序列化库。
I have an in-memory sqlite database which I want to convert to a simple blob, and I want to do this preferably without using any serialization library.
我也使用sqlite api备份调用将其序列化到磁盘,这也可以用于我的目的?
I also use sqlite api backup calls to serialize it to disk, can this also be used for my purpose?
还是,可以简单地将数据库从内存复制到任何其他方式的字符数组? (使用C ++完成开发)
Or, is it possible to simply copy the database from memory to a char array in any other way? (Development is done using C++)
推荐答案
SQLite不能直接访问内存数据库的内部存储。
SQLite does not give you direct access to the internal storage of an in-memory database.
您可以实现您自己的VFS 为一个blob创建一个文件接口,但只是通过一个(临时)磁盘文件听起来容易得多。
You could implement your own VFS to create a 'file' interface for a blob, but just going through a (temporary) disk file sounds much easier.
