用于将图像文件转换为二进制格式以存储在数据库中的C代码 [英] C code for converting an image file into binary format for storing in a database

问题描述

我想知道如何将jpg图像文件转换为二进制代码格式。它们将以这种格式存储在数据库中。

I would like to know how to convert a jpg image file into binary code format. They are to be stored in a database in this format.

推荐答案

你真的不应该这样做！您最好在应用程序中创建一些文件服务（具有唯一和原始文件名），并将文件存储在没有数据库的服务器上的某个目录中。



仅比您需要在存储时将文件复制到服务器，并在检索时将其复制回而不进行任何其他操作。它节省了大量的执行和开发时间，避免了大量的错误!!!

you really shouldnt do that! You better create some file service (with unique and the original filename) in your app and store the file in some directory on a server without the database.

Than you only need to copy the file to server on storing and copy it back on retrieving WITHOUT any additional operation. It saves a lot of execution and development time and avoids tons of errors!!!

图像已经是二进制格式，只需将它们粘贴在数据库中...我一直这样做。



你的问题太过模糊了，无论如何都不能回答....下次尝试这样的事情：



使用C风格的Windows应用程序在Oracle数据库中存储图像的好方法是什么？

Images are already in binary format, just stick them in the database ... I do it all the time.

Your question is far too vague to answer anyway .... try something like this next time:

"What would be a good way to store images in an Oracle database with a C style Windows application?"
