表示C ++中的BLOB [英] representing BLOBs in C++

问题描述

是否有任何STL容器似乎非常适合用作数据库软件的BLOB？我会认为一个向量< char> ，但有什么更好吗？也许 std :: string ？或一些非STL容器？

Are there any STL containers that seem to be well-suited for using as BLOBs for database software? I would think a vector<char>, but is there something better? Maybe a std::string? Or some non-STL container?

推荐答案

BLOB 允许存储二进制数据，因此您需要一个有序的字节集合。最简单的选择是向量<> ，您可以选择 unsigned char 表示大多数平台上的字节

The BLOB type of databases allows storage of binary data, so you need an ordered collection of bytes. The easiest choice would be a vector<> and you could chose unsigned char to represent a byte on most platforms
